2.1 SYSTEM ITEM DESCRIPTIONS (See Figure 1)
PRE-FILTER (#1): Consists of a 20” filter housing that contains a 10 micron sediment cartridge for
removal of particulate matter. The filter cap includes the feed water ¾” FPT inlet port.
PRESSURE VESSEL/MEMBRANE ASSEMBLY(s) (#2): This is where dissolved solids are sepa-
rated from the feed water. This assembly consists of 3 (6000) or 4 (8000) PVC pressure vessel(s)
that house the reverse osmosis (RO) membrane(s). PVC pressure vessels are standard on both
models. For optional pressure vessel construction, see 2.2 SYSTEM OPTIONS.
PUMP/MOTOR (#3): The multi-stage centrifugal pump boosts water pressure in the pressure
vessel/membrane assembly(s) to about 150 psig (10.3 bar) to ensure high solids rejection and high
flow rates. The motor is sized for the specific pump configuration and supply voltage requirement.
SOLENOID VALVE (#4): Electrically operated valve that prevents feed water from flowing through
the system when it is not in operation. The coil and body are separate replaceable units.
BRINE CONTROL VALVE (#5): A needle valve in the brine flowmeter that controls both the amount of
water flowing across the membrane(s) that goes to drain and membrane pressure.
RE-CIRCULATION VALVE (#6): A needle valve in the recirculation flow meter that controls the
amount of concentrate from the membrane to be re-circulated back into the feed stream. This
feature allows for higher recovery rates, see 3.2.2 OPERATING PARAMETERS for guidance. This
valve affects system operating pressure, brine flow rate and TDS.
PRE-FILTER IN/OUT GAUGES (#7): These gauges display the feed water pressure before and
after the sediment pre-filter. The operator can use this to observe pressure drop through the filter
as a means of detecting filter clogging to know when it is time to replace the element (See Section
7.4). For additional gauge options, see 2.2 SYSTEM OPTIONS.
VESSEL-IN/OUT GAUGES (#8): These gauges display the operating pressures at the inlet and
outlet of the membrane(s)/vessel(s). These pressures are used in the setup of the unit and as an
early warning of membrane fouling or degradation. For additional gauge options, see 2.2 SYSTEM
OPTIONS.
LOW PRESSURE SWITCH (#9): A pressure switch that shuts off the unit in the event of low feed
pressure (filter outlet). This is used as a pump protection device. It is factory set to cut off if the
pressure drops to 12 psi (0.8 bar). A minimum of 22 psi (1.5 bar) is required to originally start the
RO. The unit does not automatically restart if the loss of water pressure was temporary due to
some other water usage. It is necessary to evaluate the pressure loss situation, make the neces-
sary corrections and then restart the unit with the start switch (see #15 below).
MICROPROCESSOR CONTROLLER (#15) The PLC controls all functions of the RO System
including product conductivity monitoring. The PLC controls the RO system on/off from product
tank level, pre-treatment systems with auto backwash and from feed water pressure fault. This on/
off function controls the feed water solenoid valve and the main pump. An optional fast flush on
startup, tank full or at both times is also available. If the unit shuts down after turning the POWER
ON/OFF switch to ON it will be necessary to take corrective action. This condition may be due to
the feed water pressure momentarily dropping below the cutoff level and not recovering within the 2
second delay allowed by the controller. In this case it will be necessary to provide a higher capacity
feed to the RO system or to lower the low pressure cutoff switch setting. To adjust the low pressure
cutoff switch setting, see 7.1 LOW PRESSURE SWITCH ADJUSTMENT.
6

CONTROL PANEL (#16): The panel is white ABS. This panel is standard on all units. It provides
mounting for the main POWER switch, microprocessor controller, gauges and flow meters with
valve(s).
FRAME (#17): The frame is formed and welded of stainless steel. The pump mounting plate is mild
steel, powder coated and bolted in place on the SS frame. The SS frame provides a mounting for all
the RO system components.
LEVELING FEET (#19): These allow for a stable mounting on an uneven surface. After adjustment
of the feet, snug the looking nuts against the under side of the frame.
MAIN POWER ON/OFF SWITCH (#20): The RO system is completely unpowered when this switch
is in the off position.
2.2 SYSTEM OPTION DESCRIPTIONS (See Figure 1)
PRESSURE VESSEL/MEMBRANE ASSEMBLIES (#2): PVC pressure vessels are available.
TANK PRESSURE SWITCH (not shown): An electrical switch used with a pressurized storage tank
that controls the system operation based on the storage tank pressure. This is factory set to shut
the system off when the tank pressure is 60 psi (4.2 bar) and turn the system on when the tank
pressure is below 40 psi (2.8 bar). The option includes a check valve for the product water line to
prevent back flow to the membranes when the system is not running.
PRODUCT WATER CHECK VALVE (not shown, part of the tank pressure switch option): A one-way
valve that prevents pressurized product water from flowing back into the desalinator (and possibly
damaging the membrane) when the system is off. The product water check valve is only required
when using a pressurized storage tank. However, presence of this valve will not affect operation
with a non-pressurized storage tank.
TANK FLOAT SWITCH (not shown): Installed in an atmospheric storage tank to control system
operation from tank low and tank full. (See #15 in 2.1 SYSTEM ITEM DESCRIPTIONS)
BLENDING VALVE (not shown): The blending valve allows the addition of filtered feed water to the
product of the RO system. This is done when the product of the RO system is a lower TDS than is
necessary or desired.
AUTO FLUSH SYSTEM (not shown): The auto flush system flushes the concentrated brine from
the RO membrane(s) with filtered feed water, at a high flow rate. The high flow rate provides a
scrubbing action on the membrane feed surface. The flush is automaticall performed for a preset
period of time on each automatic shutdown of the RO system (on storage tank full condition). The
flush time is set at 5 minutes. This option is generally incorporated with high fouling feed water as
an aid to extending membrane life.

2.4 SYSTEM CONTROLLER
This system is equipped with a microprocessor controller which monitors several functional condi-
tions and regulates operation of the high pressure pump and control valves. The controller is con-
nected to sensors which, depending on their state, allow the cyclic production of purified water or
prevent operation due to abnormal conditions.
Standard Configuration
In the standard configuration the following parameters are monitored and affect system operation:
Feed Water Supply Pressure.
The feed water pressure sensor must detect a pressure of at least 22 psi (1.5 kpa) at the outlet of
the system prefilter before the controller will allow the system to start. If the feed water pressure
drops below 12 psi (0.8 kpa) during system operation the controller will shut down product water
production. After a one minute delay the controller will restart if the feed pressure has risen to 22 psi
(1.5 kpa) or higher. If the restart fails for three attempts the controller will cease trying and remain in
the standby state and display the ALA message. The OFF-POWER-ON switch must then be turned
to OFF and then ON to reset the controller
Product Water Storage Tank Level.
The controller should be connected to a “normally closed” or “pump up” type of tank float switch.
The contacts in this switch will be in the closed state whenever the tank water level is below the full
level. When the full level is reached, the contacts should switch to open state. The controller will
turn the system on to produce water as long as this switch indicates that the product water tank is
not full and as long as the other sensor inputs are in a normal state.
Product Water Conductivity.
The controller is connected to a product water conductivity sensor located near the product water
outlet connector. The conductivity measurement value will be shown in the controller display during
normal operation. If the conductivity value exceeds a preset maximum level the HIGH indicator will
light red on the front panel.
Optional Configurations
The system controller may also be monitoring the following optional parameters depending on the
options included in the specific system.
Low Feed Water Tank Level
In certain configurations, feed water to the system is supplied by a boost pump drawing from a feed
water storage tank. If the proper float switch is installed in this tank the system controller will monitor
this switch and if the feed tank level drops below the minimum level the controller will shut down the
R.O. system including the boost pump.
High Vessel In Pressure
In certain configurations, particularly with sea water systems which employ a high pressure positive
displacement pump, a pressure switch is installed on the high pressure pump outlet. If the pump
output pressure exceeds the trip setting of the pressure switch the controller will shut down the R.O.
system and display the ALA alarm indication.
Membrane Flush
If the membrane flush option is installed the controller will execute either a feed water fast flush or a
product water flush, depending on the selected configuration. The flush mode can be selected for
occurrence at either startup or shutdown, or at both startup and shutdown. Refer to the Flush Mode
setting instructions later in this manual in paragraph 3.2.3.

3.0 PRE-INSTALLATION PROCEDURES
PLEASE READ CAREFULLY. FAILURE TO FOLLOW THESE PROCEDURES CAN RESULT IN
DAMAGE TO YOUR SYSTEM AND VOID YOUR WARRANTY.
3.1 PACKAGING
Upon delivery, inspect for external signs of damage and report any damage to your delivery carrier at
that time. After unpacking the system, inspect it carefully for signs of damage. All damage claims
should be made to the delivery carrier.
3.2 RO SYSTEM OPERATION
3.2.1 FEED WATER CONSIDERATIONS
Tomar TV-Series are to be used on microbiologically safe water that conforms to operating param-
eters per 3.2.3 only. The user must be sure that water, to be treated, is both microbiologically safe
and non-toxic. Ensure that the operating parameters outlined in 3.2.3 are met at the installation site.
Items of most importance are TDS, supply water pressure, flow rate, chlorine level and temperature
range.
A water analysis is helpful in determining if any pre-treatment is needed. If your water analysis
shows levels of substances in excess of the maximums stated in 3.2.3 or has TDS greater than
500, contact your dealer or Tomar for any pretreatment that may be required, and/or the maximum
allowable recovery without pretreatment.
3.2.2 OPERATING PARAMETER SETTINGS
The TV-Series operates according to the following parameters, where:
Qs=Feed water flow rate
Qb=Brine flow rate
Qr=Recirculation flow rate
Qp=Product flow rate
Qro=Flow rate to the RO vessels (pump output)
Qs=Qb+Qp Qro=Qs+Qr Recovery=Qp/Qs
The system RO pump is a multi-stage centrifugal type pumps running at 3450 rpm for 60 Hz opera-
tion and 2875 rpm for 50 Hz operation. This type of pump runs essentially at full motor horsepower
through the normal pressure and flow operating range of the pump. Pump flow and pressure are
controlled by adjusting the brine flow rate (Qb). Do not close the brine valve any further than is
necessary to develop 100 to 150 psi for the low energy membranes and 200 psi for high rejection
membranes. In any case, never increase pressure to the extent that the combined brine and
recirculation flow is less than 6 gpm for the TV-8000 or 3 gpm for the TV-6000.Concentrate water
(brine) flows to the drain. This waste can be reduced by recirculating some of the concentrate flow
back to the pump. The amount of recirculation (Qr) reduces the amount of feed water (Qs) by the
same amount, which increases the rate of recovery. However, recovery should not be greater than
70%. Higher recovery reduces the rejection of salts, which will be observed on a TDS Monitor. Set
the recirculation flow rate (Qr) to the maximum level with the system still producing RO water with
an acceptable TDS level. However, for high TDS feed water it is advisable to keep the recovery low
to avoid possible fouling of the membranes. Tomar can provide a projection from your water analy-
sis to determine safe operating parameters for your system.

3.2.3 CONTROLLER OPERATION
Following are the controller panel indications possible under various system conditions:
SLP = Standby Mode
XXX = Product water conductivity (press C/T button to read cond.)
XX.X = Product water temperature in degrees C (press C/T button to read temp.)
FULL = Product water tank full
ALA + HIGH PRESS LED RED = High pressure pump output over limit (optional feature)
ALA + LOW PRESS LED RED = Feed water pressure under limit
ALA + LOW FEED PRESS LED RED = Feed water storage tank level low (optional feature)
ALA + HIGH LED RED = Product water conductivity over limit
Green LED displays on the controller panel indicate that the parameter is within normal limits or that
the element (pump or valve) is active. Flush mode settings may need to be set initially and after any
power interuption to the controller. To change settings on the controller proceed as follows:
1. Press the SET button. The conductivity calibration factor will appear. This value has been
factory set and should not be changed.
2. Press the SET button a second time. The value displayed is the high limit for product water
conductivity (in microseimens). Readings above this value will result in an audIble alarm as well as
an ALA display and red HIGH LED indication. To change the limit value use the arrow buttons to go
up or down. When the value is as desired press the C/T button to save the new value.
2. Press SET a third time. The display will now indicate the duration of flush that will occur when-
ever the system starts as “aXXX”. The range is from 000 to 249 seconds (4 minutes). If no startup
flush is desired or if the flush option is not installed set the value to 001 otherwise set the time to the
desired duration. When done, press the C/T button to save the value.
3. Press SET a fourth time. The display will now indicate the duration of flush that will occur
whenever the system shuts down as “bXXX”. The range is from 000 to 249 seconds (4 minutes). If
no shut down flush is desired or if the flush option is not installed set the value to 001 otherwise set
the time to the desired duration. When done, press the C/T button to save the value.
4. Press the SET button a fifth time. The number now displayed as “C-XX” indicates the interval in
continuous running that the system will stop and automatically go into a shut down flush, and then
resume running after the flush is complete. The value range is 00 to 99 hours. If no automatic flush
is desired, set the value to 99 hours otherwise set to the desired interval. Again, this feature is only
active if the flush option is installed. If not, set the value to 99. Press the C/T button to save the
value. Pressing the SET button one last time will return the display to normal indication.

3.3 PRE-TREATMENT
For the TV-6000 and TV-8000 systems a 2.5” x 20” carbon block filter in the system frame filter
housing will not be practical for proper de-chlorination of the feed water supply. The high rate of feed
flow will deplete the 20” cartridge in a very short time. To properly de-chlorinate the water supply
feeding the TF membranes; an adequate capacity granular activated carbon (GAC) back-washing
filter should be used. Similarly, if the feed water contains any appreciable level of turbidity or par-
ticulate fines, a separate backwashing media (typically sand) filter should be installed ahead of the
TV system.
4.0 INSTALLATION
PLEASE READ CAREFULLY. FAILURE TO FOLLOW THESE PROCEDURES CAN RESULT IN
DAMAGE TO YOUR SYSTEM AND VOID YOUR WARRANTY.
4.1 LOCATION
It is recommended that systems be located where they are protected from harsh environments such
as rain, snow and extreme temperatures (both hot and cold). The TV-Series is intended for indoor
installation. TV-Series systems can be located just about anywhere inside where there are water
and electrical supplies and a drain for the brine discharge. Keep in mind, however, that they should
be out of normal traffic patterns but easily accessed for daily monitoring and service. The hazards
of flooding in the event of system failure should also be considered in the location selection.
4.2 PLUMBING (see Figure 2)
Always adhere to local plumbing codes when installing the system. When installation procedures
conflict with your local plumbing codes, STOP and contact your dealer or Tomar.
Connect a feed water supply line to the pre-filter inlet (the filter is 3/4” fnpt on the left side).
The product and drain line connections are ½” tube QC fittings at the lower rear of the unit and they
are so marked. Connect 1/2” OD tubing at these ports.
4.2.1 WATER SUPPLY CONNECTION
If the supply water is being drawn from a non-pressurized tank, a boost pump will be required to
overcome filter backpressure and maintain about 25 psi (1.7 bar) to the pump. When the RO starts
there will be a momentary drop in feed water pressure. During this start-up, if the source feed
water system can not maintain a pressure above the cutout pressure of the low pressure switch (12
psi), the following options are possible:
1) If the pressure drop is not more than, say, 6 psi below the 12 psi factory setting, the low
pressure switch setting can be lowered. (See 7.1 LOW PRESSURE SWITCH ADJUSTMENT)
2) A 10-gallon bladder tank can be added at the feed filter inlet to help hold the pressure from
dropping below the cutout setting of the LP switch. The bladder tank also reduces recovery time. If
the feed pressure drops below the cutout point and can not recover to at least 22 psi quickly the use
of the tank will not help.
3) The following should only be used as a last resort since it results in added cycling on and off
of the RO system. Usage is indicated when the unit is able to start normally; then during operation
13

another usage in the building drops the pressure below the low pressure switch cutout point (a
flushing toilet for example). Remove the controller enclosure cover and at the top right of the board
(on the cover), move jumper J5 to position A. With this jumper setting the controller will automati-
cally restart in 30 seconds providing that the feed pressure has returned to normal. (See Micropro-
cessor Controller Attachment Sheet)
4.2.2 DRAIN CONNECTION
Connect 1/2” OD tubing to the DRAIN QC fitting (1/2” ID to barb fitting for the TV-8000 system)
located on the lower rear of the system frame and run to a convenient drain. Be sure to check your
local plumbing codes to see if an air gap between the system and the drain is required. If the flush
option is installed in the system there is a 1/2” OD tubing line to be run to the same drain as the
brine tubing.
4.2.3 PRODUCT CONNECTION
The PRODUCT 1/2” FNPT fitting is at the lower rear of the system frame. Make this connection to
an atmospheric storage system, or if your TV was ordered with the pressure tank switch option you
may connect a pressure tank sized per your requirements and the TV system production rate. The
product water connection to storage tanks should not be made until the system is flushed and tested
as outlined in 5.0.
4.3 ELECTRICAL (See Figure 3)
WARNING!
DO NOT CONNECT POWER UNTIL THE SYSTEM IS COMPLETELY INSTALLED AND
READY TO RUN. ALL ELECTRICAL WORK SHOULD BE DONE BY A QUALIFIED
ELECTRICIAN IN CONFORMANCE WITH ALL APPLICABLE ELECTRICAL CODES.
TV-Series systems come standard with bare power leads for either hard wiring to a disconnect box
or for installation of the proper power plug. Be sure the receptacle you use is on a circuit that has a
Ground Fault Interrupter (GFI) and has sufficient capacity for the operating current as listed in 1.0
SYSTEMS SPECIFICATIONS. It is recommended that the unit be installed on a dedicated circuit
panel with the correct circuit breaker or fuse sizes installed (see Figure 3). The power cord is so
labeled and extends from the front left side of the TV system.
Wire leads are provided for TV-Series control from pretreatment equipment and your product stor-
age system. Do not connect electrical power to these leads in any way. The wires are red and
black. These leads are wire nutted together at the factory. All external switches must be closed for
normal operation. These wire leads are marked “pre-treat” and “tank level” and are stowed at the
bottom of the PLC enclosure.
The Electrical Schematic is all-inclusive. Your unit may not include all the components shown.
RO units requiring 460 volts (575 volts in Canada) require an additional transformer. This trans-
former will generally be rated at 100 VA and is single phase. It can be set-up for 110 or 220 volt
output or both depending on the equipment it will operate. The basic need is to drop the voltage to
the RO system control circuit. If 110 or 220 single-phase power is available, the control circuit can
be wired for this power as an alternate to the transformer.
4.3.1 EXTERNAL FLOAT SWITCH WIRING
Remove the wire nut from the two (2) leads. Strip approximately ½” of insulation from both wires on
14

the float switch and splice to the TV leads. The float switch must be of the normally closed (NC)
type, i.e. when the switch is hanging down the contacts are closed. Remove the wire nut from the
leads on the wire marked “Tank Level” and connect to the float switch wires. Wires can be con-
nected either way, there is no polarity.
4.3.2 EXTERNAL PRESSURE TANK SWITCH WIRING
If the pressure tank switch option is ordered, the tank switch will be mounted at the tank and the wire
leads for “pre-treat are to be wired into one set of contacts in the switch. The product water check
valve will also be installed. You need only connect the product water fitting to your distribution
system and the pressure tank. If you are providing the pressure tank, check valve and tank switch,
the switch must be a normally closed (NC) type. Remove the wire nut from the leads on the wire
marked “tank level” and connect to one set of contacts in the tank switch.
4.3.3 PRE-TREAT LOCKOUT SWITCH WIRING
The pre-treat lockout switch must be wired through the normally closed set of contacts in the pre-
treatment system(s). If there is more than one equipment that must control the TV system on/off,
such as a GAC auto back wash filter and, say, a multi-media auto back wash filter, the switches in
the auto valves would be wired through the Common and NC terminals, in series,to the RO system
controller wires marked “pre-treat”. Since these contact inputs to the controller are dry contacts
there is no wire preference or polarity for making the connections.
5.0 STARTUP, FLUSH AND PERFORMANCE VERIFICATION
Although TV-Series systems are fully tested at the factory prior to shipping, it is strongly recom-
mended to flush and verify your system’s performance on-site, particularly if the unit was not in-
stalled soon after delivery.
NOTE
FOR 3 PHASE POWER DO NOT ATTEMPT TO RUN THE SYSTEM BEFORE THE PUMP
ROTATION HAS BEEN VERIFIED AS INSTRUCTED BELOW.
5.1 PUMP ROTATION DIRECTION (3-Phase models only)
Every TV-Series is thoroughly tested at the factory prior to shipment with factory 3-phase power
connected for proper pump motor rotation. Your 3-phase power connection must also be configured
for proper pump rotation. With the water supply on, turn the power switch on, then the controller
power on momentarily, and check the direction of rotation of the pump. There is a direction of
rotation arrow on the body of the pump. Observe rotation of the motor at the top end. If rotation is in
the wrong direction, reverse any two of the 3-phase power leads at your fused disconnect.
5.2 INITIAL STARTUP AND FLUSHING
New membranes have a preservative on them that should be flushed before use. Although the
system was run at the factory, additional flushing is recommended. Run the product line to a drain
and run the system as follows until the product TDS has stabilized.
Fully close the RECIRC valve by turning the knob full CW.
Fully open the brine control valve by turning the knob full CCW.
Turn on the water supply to the unit and check for leaks up to the solenoid valve.
Turn the OFF-POWER-ON power to ON.

After the system has run for a few minutes turn the BRINE valve clockwise until the system pres-
sure gauge reads 150 psi (10.3 bar) or a product flow rate of 4 GPM (15 l/min) for the TV-6000 or 5.5
GPM (21 l/min) for the TV-8000. At this point the RECIRC vallve can be opened and the BRINE valve
closed in coordination so that the VESSEL IN pressure stays close to the 150 psi point.. The
BRINE flow should not be allowed to drop below 2 GPM for the TV-6000 and 3 GPM for the TV-8000.
If the feed water mineral content is very high the BRINE flow rates may need to be increased some-
what to minimize membrane fouling. For very high feed water TDS an antiscalant injection system
is recomended. Fully open the concentrate recirculation valve (if system is equipped) by turning the
knob CCW.
Allow the system to flush with all water discharged to drain. Periodically check for leaks and check
the system vessel-in pressure gauge. It is likely that the pressure will drift from 150 psi (10.3 bar)
during the flushing; if it does, adjust the concentrate valve to correct the pressure back to the original
setting. DO NOT LET SYSTEM PRESSURE RISE ABOVE 200 PSI (13.8 bar). When pressure,
flows and TDS have stabilized turn the unit off, connect the product line and re-start the unit.
5.3 PERFORMANCE VERIFICATION
Factory test data is supplied with the system at the end of this manual. This data reflects unit
performance with municipal water available at the factory. To ensure optimum performance, on-site
data should be taken and compared to the factory test data. This data should be taken after the
system has been flushed for one hour. Some deviations may be seen due to differences in feed
water TDS and temperature between the site and factory. If you have already connected the product
line to the tank, you will need to disconnect it ahead of the post carbon filter (if one is installed) to
take product samples.
5.3.1 FLOW TESTS
This testing is needed only if the unit is not equipped with the full flow meter complement. Deter-
mine the flow rates for both product and concentrate (brine). Put the product line into a graduated
container and measure the volume of water that flows into it in one minute. Repeat the process with
the concentrate (labeled BRINE) line. These values should be in either gpm or ml/min.
5.3.2 RECOVERY
Compute the recovery according to the following formulas: Recovery = Qp/Qs where Qs=Qb+Qp,
as discussed in 3.2.2 OPERATING PARAMETERS.
5.3.3 REJECTION
This testing is needed only if the unit is not equipped with the standard TDS meter. Using a conduc-
tivity meter (TDS meter) measure the TDS in both the feed water and the product water. Calculate
percent rejection using the formula below:
(Feed TDS-Product TDS) / (Feed TDS)* 100 = % Rejection
Rejection should be 96% or better. For example, where the feed TDS is 600 and the product TDS is
24, the percent rejection is:
(600-24)/ 600*100 = 96%.

5.3.4 LOW PRESSURE SWITCH TEST
While the system is running, slowly shut off the water supply to the system. The system should
shut off at about 12 psi on the filter out gauge. If the system does not shut off by at least 7 psi,
reestablish the water supply. DO NOT LET THE SYSTEM RUN WITHOUT AN ADEQUATE
WATER SUPPLY TURNED ON. PUMP DAMAGE WILL OCCUR. Turn the system off and refer to
7.1 for low-pressure switch adjustment.
5.3.5 OPTIONAL TANK PRESSURE SWITCH TEST
Generally, the TV-6000 and 8000 would be used with large atmospheric product water storage tanks.
However, if a pressurized tank is indicated perform the following check. With the product line con-
nected to the tank and usage demand on, and with the TV system running, slowly close the usage
demand. The tank pressure gauge should start to rise as the tank fills. The system should shut off
when the gauge reads about 60 psi (4.2 bar). Now, by opening the usage demand the tank pressure
should begin to drop, and the system should turn on when the pressure drops below about 40 psi. If
the system fails to shut off at 60 psi, watch the gauge and be sure that it does not rise above 70 psi.
If it reaches 70 psi, turn the main POWER switch to OFF. Refer to 7.2 for tank switch adjustment.
5.3.6 FLOAT SWITCH TEST
The system should run when the float switch in the atmospheric product storage tank is hanging
down by the cord (not in contact with water). Slowly tilt the float switch up to its highest position so
the cord is at the bottom of the float. The unit should shut off. If the unit does not shut off, re-check
installation as outlined in 4.3.1. Improper float installation could result in an overflow of the tank or
too frequent start and stop of the pump.
5.3.7 OPTIONAL BLENDING SYSTEM
Start the RO with the valve closed. The TDS meter is reading the product water quality as produced
by the RO system. Allow the TDS to stabilize, then gradually open the blending valve allowing time
for the new TDS reading to stabilize. Adjust the valve to product the desired product TDS.
5.3.8 OPTIONAL AUTO FLUSH SYSTEM
The auto flush is normally set at 5 minutes. Check operation by simulating a tank full condition
(example, tilting the float switch up in an atmospheric tank). Maintain the switch in the tank full
position and observe that the flush function starts. Check the elapsed flush time to verify the timing
setting. When the switch is returned to a tank low condition the system will restart.
6.0 MAINTENANCE
Tomar TV-Series systems are designed for simple operation with periodic monitoring of critical
functions. Tomar recommends keeping accurate performance records and following a regular
preventive maintenance schedule to maximize the life of your system. A performance record sheet
is provided at the back of this manual for you to copy and keep near your system. This record sheet
will be important for warranty verification and trouble shooting, as well as possibly suggesting more
or different pre-treatment.
6.1 DAILY SYSTEM CHECKS
Your water supply pressure can vary from time to time. This can also affect your system operating
pressure. Therefore, it is recommended to check and adjust your system pressure daily to ensure
maximum water production rates and quality. Check both the water supply pressure gauge (Filter In
gauge) and the Filter Out gauge. Under normal conditions, there should be a 3-5 psi difference
between the two gauges. When the difference reaches 10 psi or if the Filter Out gauge reading is
close to the 12 psi cutout point of the low pressure switch, a pre-filter change is recommended. See
7.4 for further discussion on cartridge replacement.
