Familiarization With Alpha
The Alpha machine consists of several separate items which
must be installed.
■The most obvious component is a stainless steel separa-
tor tank which is the heart of the Alpha. Take a minute
to become familiar with this machine.
■Additional items furnished with the Alpha include:
• Perforated sump pump protection/installation
container.
• Sump pump level on/o oat control for pump.
• 1-1/2" x 16' (3.81 cm x 4.89 m) recycle hose.
• 1-1/2" (3.81 cm) ball valve for recycle system.
• 1-1/2" x 25' (3.81 cm x 7.62 m) inlet hose with quick
connect (cut to length as needed).
• Drain valve manifold
Leveling Alpha Machine
The Alpha Machine must be set level both side to side and
end to end. This is important to assure the machine will
give you optimum performance.
Sump Pump/Level Control
■Your Alpha comes with a prepackaged perforated pro-
tection container for the sump pump. This container is
designed to protect the pump from clogging and dam-
age from debris.There is a level on/o control attached
to the pump which plugs into the Alpha and then the
pump plugs into the oat control on the Alpha only
installation.
• Insert the Level Control Float Tree into the strain
relief provided on top of the sump pump container
provided.
• Float tether length must be a minimum of
2" (5.08 cm ) long.
• The turno point for the oat level control must be
2" (5.08 cm) above the pump container.
If you have the optional Auto Discharge Kit, refer to
page 20 for proper oat location.
• The oat must travel its complete arc without:
- Water going over top of pit
- Float touching side walls or bottom
- Float interfering with electrical wiring, plumbing,
bottom or side walls of pit, or any other object.
■Lower the sump pump container, with pump and oat
attached, into the sump. Check to assure the oat can
operate freely.
■Connect the pump hose to the inlet of the Alpha. This
is a quick connect camlock tting; be sure it is secured.
■Plug the oat into the electrical outlet on the Alpha and
then plug the power cord for the pump into the back
of the oat.
■Secure the electrical cords of the pump and the oat to
1-1/2" (3.81 cm) water hose with nylon tie wraps.
Discharge
Connect the 1-1/2" (3.81 cm) discharge line to the male
camlock with the other end into the proper sewer discharge
(see Figure 4).
For discharge, close the recycle ball valve. During the night
or on weekends and holidays, open the recycle ball valve.
Add water to the collection pit until the pump starts.
Connect 1-1/2" (3.81 cm) hose to the recycle port on the
Alpha (see Figure 4). The recycle line should be plumbed
back to the collection pit so when the Alpha is in the re-
cycle mode, the water in all the pits is circulated to control
bacteria.
ORP/pH Controller Option
Install pH/ORP injectors and sensors per drawing on page
28. Install sensor into pipe so sensor tip is half way into pipe,
touching uid, but not touching bottom of pipe. Follow
instructions on page 14 to 15 and instructions that come
with controller.
Auto Discharge Option
Tie wrap the N/C and N/O oats to discharge pipe coming o
sump pump. Position both oats at the same level towards
the upper part of the pit.
Run oat wires to electrical box on Alpha and wire according
to wire diagrams.
When the water level rises and lifts the oats in the pit, the
electric auto discharge valve rotates to discharge water.
When the water level drops and oats fall, the electric ball
valve rotates and directs water back to the pits.
Electrical
The machine, when installed, must be electrically grounded
in accordance with local and/or national codes. Check for
proper electrical supply. Plug the cord into a 120V 15 amp
electrical outlet. It is recommended that a Ground Fault
Circuit Interrupter be installed in the circuit breaker for all
Wash-Water equipment.
NOTE: Always test all electrical outlets for proper voltage
before plugging in any equipment.

Start-Up:
Add water to the sump to activate the oat switch.
Turn the sump pump switch on the Alpha to“ON” (see
Figure 1).
Adjust the length of the Float Level Control to the de-
sired level.
Add additional water to the sump (or Alpha directly)
until the Alpha is full of water (water is exiting the out-
let).
Adjust the height of the gate inside the Alpha that
controls the ow into the oil skimmer. Skim o the oil
with a small amount of water. The oil will stay in the oil
skimmer while the water returns to the pit through the
return line.
Check the machine for leaks (the machine was hy-
drostatically tested at the factory but may have been
damaged in shipment).
Check that the machine is level side to side by observ-
ing the ow over the baes. Shut o the inlet valve and
gradually reopen it. At low ow rates when the machine
is level, ow will be even across the complete top of the
bae.
Check level, end to end, by observing the water level
in relation to the coalescing pack.
Check the overow shuto switch by manually lifting
the liquid level switch (see Figure 3).
Check the recycle line to make sure the water is owing

OPERATION
After start-up, the only operational adjustment on the Al-
pha is the inlet ow control valve (see Figure 1). Your sump
pump owrate may exceed the Alpha’s oil/water separation
capacity. Throttle the valve on the Alpha until the incom-
ing water is the same ow as the recycle water through the
recycle line going back to the collection pit.
This will give adequate ow through the ozone injector
to meter the ozone generator properly (see Figure 8). If at
anytime the incoming ow is adjusted, the ozone generator
must be metered again.
GENERAL MAINTENANCE
AND SERVICE
Periodic Maintenance
Oil Skimmer Collection Tank
Monitor the level of oil in the oil skimmer. Empty
as needed.
Solids Removal
Settled solids are collected in the inlet solids collection
chamber. The solids must be removed periodically as
dictated by the dirt load coming into the machine. The
procedure for removal is as follows.
• Disconnect the machine from the electrical power
source.
• Before opening the drain valve, be sure the ow
of solids is directed to the collection pit. Open each
drain valve individually and remove the solids.
• Remove the vertical coalescing pack (see Figure 3
for location).To remove, lift with the nylon strap that
surrounds the coalescing pack.
• After removal of the vertical coalescing pack, hose
out the remaining solids in the bottom of the
chamber.
• Replace the vertical coalescing pack and close valve.
NOTE: The vertical coalescing pack can be cleaned, if
desired, by washing it with a garden hose or a pres-
sure washer.
• If the solids chamber cannot be drained back to the
collection pit, you can use a shop vac for the Alpha
1500.
Service
Check the electrical cords to assure they are safe, with
no damage or cracking.
Check the inlet and outlet hoses for leaks or damage.

CHEMICAL MAINTENANCE
PROGRAM
Owner Chemical Maintenance Program to
Maintain Water Quality:
Daily monitoring and adjustment of WATER MAZE water
chemistry is essential. If not monitored and controlled, the
recycled water becomes chemically unbalanced, resulting
in a host of problems such as algae and bacteria growth,
obnoxious odors, iron discoloration and ultimately is unt
for reuse or sewer discharge.
The daily monitoring and adjustment maintenance pro-
gram, if followed, will provide suitable water. The proper
maintenance of the water is not complicated and depends
upon a few basic principles:
1. PHYSICAL - eective ltration and recirculation of
the water
Eective recirculation of the water through the collection
pit, and the Alpha system is achieved only if the system is
utilized often (daily 6-8 hours or more) or if the system is set
to recirculate the water throughout the total system. WATER
MAZE has provided controls and procedures to achieve
continuous eective water recirculation throughout the
process. The Alpha, when operated properly, achieves ef-
fective ltration and recirculation.
2. CHEMICAL - proper adjustment of alkalinity and pH
The most important factor to control and maintain is the
pH of the water (i.e. the acidity or alkalinity). If the water is
acidic (low pH) it will dissolve iron into solution. The pres-
ence of iron of more than 0.2 ppm will result in rusty stain-
ing of virtually anything the water comes in contact with.
Alkaline water can cause cloudiness and greatly reduces the
eectiveness of chlorination. Many cleaning detergents are
alkaline and will make the water too alkaline. The proper pH
range to maintain is 6.8 - 7.2.
Alkalinity refers to the soluble salts in the water. These
include bicarbonates, carbonates, hydroxides and other
alkali compounds. The water's total alkalinity controls its re-
sistance (buering ability) to large uctuations in pH levels.
Another factor which should be monitored for proper water
chemistry balancing is calcium hardness. The presence of
too much calcium can lead to the formulation of scale.
3. BIOLOGICAL - adequate disinfection, bacteria, and
odor control
Chlorination and ozonization are used to control bacteria,
and odor formation. For chlorine to be eective, it must be
available as free chlorine. If the proper pH and alkalinity is
not maintained, or if the water contains dirt particles, the
chlorine will be combined chlorine and not be eective in
the control of algae and bacteria growth. Combined chlorine
has only 1/15th the strength of free chlorine.
Inadequate or improper addition of chlorine could result in
bacteria growth. Once bacterial growth starts, the system
must be shock treated. It is best to minimize the chances
of bacteria problems.
The killing of bacteria by chlorine exists in two phases:
1. The penetration of the active germicidal principal (hy-
pochlorous acid) into the bacterial cell and
2. The chemical combination of this ingredient with the
protoplasm (the complex composition which forms the
essential part of plant and animal cells). This combina-
tion is directly responsible for the death of the organism.
The activity of this germicidal eect is reduced in alkaline
solutions (those with a pH greater than 7.5) and expressed
as follows:
pH % of Eectiveness
4.0 100.0
5.0 99.6
6.0 95.8
7.0 69.7
8.0 18.7
9.0 2.2
10.0 0.2
Hypochlorite when added to solutions with a pH lower
than 6.0 can produce oxide which is toxic. In vehicle wash-
ing, almost all cleaning compounds are alkaline in nature.
Hypochlorite will still control bacterial growth and thus
smell at higher alkaline ranges, but as the table indicates,
its eectiveness is reduced.
To compensate for this inhibited activity, a larger quantity
of hypochlorite is used. This controls bacterial growth, but
also increases operational costs.
Typical hypochlorite has a pH of approximately 11.6. This
high pH increases the pH of holding tank water, making
pH adjustment more dicult.
Trichloro-S-Triazine Trione is a chlorine compound which has
a pH of 3.0 and when added to holding tanks aids in the
reduction of tank pH levels.
Unlike hypochlorite, which is usually 15 percent chlorine and
will produce sodium or calcium salts in holding tanks, these
new products are 99 percent chlorine which means that if
a solid “puck” of chlorine is used, the total eectiveness of
the puck is superior to that of hypochlorite and no negative
by-products are produced.

ALPHA 1500 • #8.913-964.0-F
OPTIONAL ORP/PH DIGITAL
CONTROLLER  MODEL 250
The Oxidation Reduction Potential (ORP) and pH of the water
stream are controlled automatically by the digital control-
ler. The controller receives input from the ORP sensor on
the activity of the sanitizer and input from the pH sensor
on the pH level of the waste stream. The level of ORP and
pH being sensed and the requested levels programmed in
the controller will determine if outputs from the controller
are sent to the feed pumps. If sanitizer or pH adjustments
are needed, the output will turn the corresponding feed
pump on. This will inject the required sanitizer or pH until
programmed levels are reached and the feed pump will stop.
Acid/Base Jumper
Because most systems are dealing with a high pH situaton,
the controller is factory set for acid feed. If you require a
base feed, turn power o to entire system. Open plastic
door on the controller, remove the four screws on display
board, carefully pull back board and turn over. Reposition
the JP14 jumper to the base position. Return board and
door to original position.
Start-Up
Turn switch on right side of controller to the "ON" position.
Upon power-up the controller will display "109" and then
"ACD" for acid feed or "BSE" for base feed, depending on
your requirements.
Feed Mode
The feed mode for the pH and sanitizer can be set to "OFF",
MANUAL or AUTOMATIC. Set to Automatic. To select the
desired feed mode, press [ORP] or [pH] until the correspond-
ing LED indicator light is illuminated. There is a short delay
before activation. NOTE: Holding the switch for more than
5 seconds resets the setpoint and calibration for [ORP] or
[pH] to original factory values.
ORP Control Setpoint
The ORP setpoint is factory set at 550mV, which is recom-
mended to maintain water quality by killing germs and
bacteria. There is no need for ORP calibration.
The sanitizing concentration required to generate a de-
sired ORP value varies with pH and overall water quality,
particularily Total Dissolved Solids (TDS) concentration and
organic load.
To change the ORP control setpoint:
Press [SETPOINT].
Press [ORP]; the display ashes
Use [UP] and [DOWN] arrows to adjust the ORP value
Press [SETPOINT} again to save the new value.
DAILY CHEMICAL MAINTENANCE
Step 1. Collect a water sample from the outlet of the Alpha.
NOTE: Be sure that the water is circulating from the pit
through the Alpha and back to pit.
Step 2. Using the test strips supplied, measure:
A. The pH.
B. The residual chlorine (systems with chlorine).
C. The alkalinity.
D. The calcium hardness.
Step 3. If the pH is 6.8-7.2 go to Step 4. If not, adjust the pH
of the water that is recycled between the Alpha and the pit
to pH 6.8-7.2. Muriatic acid or Alum can be used to lower the
pH. Soda ash (sodium carbonate) or caustic soda (sodium
hydroxide) can be used to raise the pH.
Adjust the pH gradually, allowing complete mixing after
adding a chemical. Take a new sample, read the pH and
continue to adjust gradually until the desired pH is achieved.
Step 4.The total alkalinity should be between 50-150 ppm.
If the total alkalinity is too low, add sodium bicarbonate to
raise it. If total alkalinity is too high, add muriatic acid to
bring it within acceptable range. This will also decrease the
pH. If the pH goes below 6.8, add sodium bicarbonate to
increase the pH. This procedure may have to be repeated
several times to get the pH and a total alkalinity into the
proper range.
Step 5. The calcium hardness should not exceed 25 grains.
If it is too high, some water must be removed from the sys-
tem and fresh makeup water added. Alternatively, an ion
exchange water softener may have to be added to the sys-
tem to reduce and maintain lower calcium hardness levels.
Step 6. (Systems using a chlorinator) Free chlorine levels
should be 1-2 ppm and must be maintained by adjusting
the ow through the automatic chlorinator, or the regular
addition of liquid chlorine. A 10-50% concentrated liquid
chlorine is available. Household bleach can be used, but
contains only 5% chlorine. Chlorine continually dissipates
and becomes used up and the chlorine level must be ad-
justed daily. Remember, chlorine is most eective when the
pH level is correct (7.0).
Initially, extra time is needed to achieve proper water
chemistry balance. However, once achieved, it can be eas-
ily maintained in a minimum amount of time with daily
monitoring and adjustment.

ALPHA SERIES OPERATOR’S MANUAL 15
ALPHA 1500 • #8.913-964.0-F
pH Calibration
To calibrate the pH, use a reliable, fresh test kit (Phenol Red).
Note the value of the pH and compare it to the display value.
To change the pH calibration:
Press [CALIBRATION]
Press [pH]; the display ashes
Use the [UP] and [DOWN] arrows to adjust the pH value
Press the [CALIBRATION] again to save the new value.
Out-of-Range Alarms
The out-of-range alarms are factory set at 450 and 650mV for
ORP and 6.5 to 7.5 for pH. If the ORP is below the low limit,
the red LED alarm ashes but the sanitizer feed continues.
If the pH limits are exceeded, the red LED alarm ashes and
the pH feeder continues.
To change an alarm limit:
Press [LOW LIMIT] or [HIGH LIMIT]
Use the [UP] and [DOWN] arrows to adjust the value
Press [LOW LIMIT] or [HIGH LIMIT] again.
CAUTION: Increasing the out-of-range limits may casue
overfeeding of chemicals.
ORP AND PH SENSOR
MAINTENANCE
The controller is virtually maintenance free. The
enclosure and front panel can be cleaned with a soft cloth
moistened with a mild soap and water solution or a glass
cleaner. Do not use abrasives or harsh chemicals.
Sensor Cleaning/Testing
The sensor tips must be kept clean and free from chemical
deposits and contamination to function properly. After
saturation in the waste stream, the sensors may need to be
cleaned on a weekly or monthly basis depending on the wa-
ter quality and other facility-
specic characteristics. Slow
response and inconsistent
readings are indications that
the sensors are in need of
cleaning.

To clean a sensor, carefully remove it from the compression
tting or holding bracket. Clean the tip of the sensor with
a mild liquid detergent (Joy, etc) solution. Rinse with fresh
water and soak the sensor in a mild acid solution for ve
minutes. Rinse with fresh water and reinstall the sensor.
To check sensor for proper operation place a small amount
of white vinegar, muriatic or hydrochloric acid into a cup
and place sensor probe into solution. For the pH sensor,
the needle should drop. For the ORP sensor, the needle
should rise.
NOTE: Only clean one sensor at a time. Sensors must stay
in some kind of liquid at all times.
Sensor Replacement
For preventative maintenance it is also recommended to
replace the sensors on an annual basis or as performance
diminishes.
Sensor Storage
Extended exposure to atmospheric conditions will cause the
sensor tips to dry out. Always remove and properly store the
sensors if they are to be winterized or inactive.
Store the sensors with the original cap provided, making
sure that each cap is lled with clean water. If the storage
containers have been misplaced, store the sensors indi-
vidually in small glass or plastic containers with clean water
covering the sensor tips.

receptacle. It is recommended that
a Ground Fault Circuit Interrupter be installed in the
circuit breaker for all Wash Water equipment.
11. All wiring must be performed by a qualied
electrician.
12. Make certain that the power source conforms to the
requirements of your equipment.
13. Protect the electrical cord from sharp objects, hot sur-
faces, oil, and chemicals. Avoid kinking the cord. Replace
or repair damaged or worn cords immediately.
14. Use wire of adequate size to minimize the voltage drop
at the motor.
15. Disconnect power before servicing a motor or its load.
If the power disconnected is out-of-sight, lock it in the
open position and tag it to prevent unexpected applica-
tion of power.
16. Do not touch an operating motor. Modern motors are
designed to operate at high temperatures.
17. Do not handle a pump or pump motor with wet hands
or when standing on a wet or damp surface, or in water.
18. The pump motor is equipped with an automatic reset-
ting thermal protector and may restart unexpectedly.
Protector tripping is an indication of motor overloading
as a result of operating the pump at low heads (low
discharge restriction), excessively high or low voltage,
inadequate wiring, incorrect motor connections, or a
defective motor or pump.
19. DO NOT run the pump without water. This will
damage the pump.

PUMP OPERATION
WARNING: Do not touch sump pump, pump motor, water
or discharge piping when the pump is connected to electri-
cal power. Do not handle pump or pump motor with wet
hands or when standing on wet or damp surface, or in
water. Never touch the sump pump or discharge piping
when machine is operating or fails to operate. Always
disconnect the pump cord (power) before handling.
1. The shaft seal depends on water for lubrication. Do
not operate the pump unless it is submerged in water.
Dry running (pump not pumping water) will cause seal
damage and eventual pump failure.
2. The motor is equipped with an automatic reset thermal
protector. This means if the temperature in the motor
should rise unduly, the switch will cut o all power
before damage can be done to the motor. When the
motor has cooled suciently, the switch will reset au-
tomatically and restart the motor. If the protector trips
repeatedly (cycling on protector) the pump should be
removed and checked for the cause of diculty. Low
voltage, long extension cords, clogged impeller, very
low head or lift, etc., can cause cycling. Cycling on the
protector eventually causes motor burnout.
PUMP MAINTENANCE
WARNING: Before attempting to service, disconnect power
from machine. Do not handle pump with wet hands or
when standing on wet or damp surfaces or when in water.
Failure to follow precaution can result in personal injury
and/or property damage.
NOTE: This is a dicult pump to repair, therefore only quali-
ed electricians or servicemen should attempt to repair this
machine. Improper repair and/or assembly can cause an
electrical shock hazard.
Follow recommendation from your pump manufacturer.
PREINSTALLATION
SUMP PIT INFORMATION
(For Sump Pit Installation Only)
The sump pump can be installed in a sump pit with a mini-
mum diameter of 18" (45.72 cm) and a depth of 24" (60.96
cm). (Pit dimensions less than these will cause rapid cycling
and shortened pump life). It is recommended that the sump
pit be no smaller than 2' x 2' x 3' (.61 m x .61 m .91 m). The
sump pit may be constructed of tile, concrete, steel, ber-
glass or plastic. Check local codes for approved materials.
Make sure there are no small stones, gravel, sand, dirt silt,
etc. that may clog or damage the pump and/or pump seal,
and cause pump failure. If there are stones or gravel, clean
these out before installing the pump. Test pump for proper
operation (see Operation) before installing sump pit cover.
A sump pit cover will prevent debris from possibly clogging
or damaging the pump. It will also prevent persons from
falling in and causing injury to themselves. If an existing
pit is being used, it must be thoroughly cleaned before
installation.
SUMP PUMP INSTALLATION
WARNING: This sump pump is not designed for use in septic
tanks or underground vaults to handle raw sewage or ef-
uents. It should never be used in hazardous or explosive
locations. Do not use power cord to lift motor. Always use
the handle.
1. The sump pump should not be suspended by means of
the discharge pipe or power cord. Instead it should be
resting on a solid foundation in the bottom of the pit.
Clean the sump pit of small stones, gravel, sand, dirt,
silt, etc., which could clog or damage pump, pump seal,
and cause pump failure.
2. The sump pump is designed for 115 V, 60 HZ operation
and requires a circuit of 15 amperes. It is supplied with
a 3-wire cord set with a grounding-type plug for use in
a 3-wire, grounded outlet. For safety, the pump should
always be electrically grounded to a suitable electrical
ground such as a grounded water pipe or a properly
grounded metallic raceway, or ground wire system.
3. After all piping and controls have been installed, the
machine is ready for operation.
