PUSH IN/QUICK CONNECT FITTINGS:
Push tube firmly into the fitting, all the way to tube stop. The collet (gripper) has stainless
steel teeth which hold the pipe firmly in position whilst the O-Ring provides a permanent leak
proof seal. Pull tubing to check for security. If some tube pulls out then push all the way in
again until it stops.
Ensure system is depressurized by turning off source water before removing fittings. Push
in the collet evenly toward the fitting. With the collet held in this position the tube can be
removed by simply pulling the tubing. You can use a collet release tool (available from your
dealer) or small crescent wrench. The fitting can then be re-used. If the tube has been
removed several times you may see score marks on the ends. This can lead to leaks so cut
the end off the tubing totally square with a sharp blade using care.

CONTROLLER
The Hydroid microprocessor controller includes
numerous standard features such as pressure switch
controls, TDS/conductivity monitor, pre-treatment lock
out, float switch controls, and flush valve control. The
controller displays system status, fault sensors, and
input TDS status on an easy-to-read 3-digit LED display.
PRE-FILTRATION
Hydroid systems come standard with a carbon pre-filter.
Change the pre-filter when 75,000 gallons of purified
water has been produced. Or, a 15 or more psi drop
occurs on feed gauge, when compared to the initial
startup reading. For example, if the FEED Pressure
Gauge reads 60 psi (you will need to log initial pressure
after step 10 on page 15 has been performed) the pre-
filter should be changed when the FEED Pressure
Gauge is 45 psi or below.
BE SURE TO LOG ALL DATA UPON STARTUP (PG 25)
THE SYSTEM MUST BE OPERATED ON PRE-FILTERED WATER ONLY
FEED PRESSURE GAUGE
This gauge measures the water pressure when it exits the pre-filter.
LOW PRESSURE SWITCH
The low pressure switch shuts off the system when the FEED water pressure drops below 15
psi, preventing damage to the pump. The system restarts automatically when there is a
constant pressure of 40 psi or more.
IF THE SYSTEM PRESSURE IS FLUCTUATING, AND THE SYSTEM CYCLES
OFF AND ON, TURN THE SYSTEM OFF AND ENSURE THAT PROPER FEED
WATER FLOW AND PRESSURE ARE BEING SUPPLIED TO THE SYSTEM.

Hydroid –Series User Manual
10 04/19
PUMP
The Hydroid system uses a multi-stage centrifugal stainless-steel pump. If any damage occurs
to your system’s pump, a rebuild kit is available. Contact HydroLogic for parts and warranty.
PUMP PRESSURE GAUGE
The pump pressure gauge measures the pressure of the water as it enters the first membrane
in the system.
MEMBRANES
The Hydroid system comes with USA made, Commercial-Grade Hi-Flow Membrane Elements.
Membranes separate impurities from water through the reverse osmosis process.
CONCENTRATE PRESSURE GAUGE (DRAIN)
The CONCENTRATE pressure gauge (drain) measures the pressure of the CONCENTRATE
(drain water) as it exits the last Membrane of the system. Subtracting the CONCENTRATE
pressure from the pump pressure will give the pressure drop across the Membranes.
CONCENTRATE FLOW METER (DRAIN)
The CONCENTRATE flow meter (drain) measures the amount of wastewater the system is
sending to drain as gallons/liters per minute.
PRODUCT FLOW METER (PURIFIED WATER)
The PRODUCT flow meter (purified water) measures the amount of PRODUCT water (purified
water) the system is producing as gallons/liters per minute.
BLEND VALVE
Allows for a mixture of post-carbon treated water into the RO’s PRODUCT water (purified
water) to achieve desirable PRODUCT (purified water) TDS and higher flow rates.
IF THE SYSTEM HAS AN ANTI-SCALANT FILTER, THE BLEND VALVE MUST
REMAIN CLOSED. THIS IS TO AVOID INGESTION OF ANY CHEMICALS AND
CAN BE TOXIC FOR AGRICULTURAL USE. HL 11595

SYSTEM INSTALLATION OVERVIEW
Refer to page 15-20 for detailed instructions.
CHOOSING A LOCATION
When choosing a location to install the system, select an area with enough room to remove
the membranes and easily access components and connections. Make sure there is enough
room for service to be performed on the system. Take into consideration where your electrical
power supply is located and where the nearest drain is located. Do not install system in direct
sunlight, high intensity lights or subject the system to temperature extremes (see operating
limits chart) and/or excess humidity. The Hydroid system should be secured in compliance with
state and local regulations.
INLET 1/2" QC FITTING (FEED)
Locate the ½” QC fitting on the right side of the system labeled “FEED”.
Attach the inlet tubing to the system.
FEED LINE MUST BE AT LEAST ½”(PROVIDED).
SYSTEM REQUIRES A CONTINUOUS FLOW OF WATER
WITH A MINIMUM FEED PRESSURE OF 40 PSI, NOT TO EXCEED
85 PSI.
PRODUCT 1/2" QC FITTING (PURIFIED WATER)
Locate the 1/2” QC fitting on the right side of the system labeled
“PRODUCT”. Attach product tubing to system.
ENSURE THAT THE PRODUCT (PURIFIED WATER) CAN FLOW FREELY WITH
NO BACK PRESSURE. BACK PRESSURE CAN CAUSE IRREVERSIBLE
DAMAGE TO THE MEMBRANES.
THE PH OF THE REVERSE OSMOSIS PRODUCT WATER (PURIFIED WATER)
WILL TYPICALLY BE 1 OR 2 PH UNITS LOWER THAN THE FEEDWATER PH.

Hydroid –Series User Manual
12 04/19
CONCENTRATE 1/2" QC FITTING (DRAIN)
Locate the 1/2” port on the right side of the system labeled
“CONCENTRATE”. Run the concentrate line to an open drain in a free
and unrestricted manner (no back pressure).
ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE
CAN CAUSE BACK PRESSURE, WHICH WILL INCREASE
THE SYSTEM’S OPERATING PRESSURE. THIS CAN
RESULT IN DAMAGE TO THE SYSTEM’S
MEMBRANES AND COMPONENTS.
ELECTRICAL
The Hydroid system is 110V, 60 Hertz Single Phase, 10.6 amps, and is equipped with an eight–
foot electrical cord.
Ensure that the electrical circuit supplying the system is compatible with the requirements of
the Hydroid.
TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE INCOMING POWER
SUPPLY MUST BE A GFI OUTLET.
IT’S RECOMMENDED THAT THE SYSTEM HAVE A DEDICATED POWER
SOURCE.
TANK
Hydroid systems may be connected to a bladder tank or a storage tank with a float valve. The
float valve shuts off the system when the tank is full and opens when the water level in the tank
drops. Bladder tanks and storage tanks with float valves can be obtained by your local dealer
or distributor. If a storage tank with float valve is to be used, install it at this time.

1. Remove dust caps and short tubes from all ports: PRODUCT (purified water - blue tubing),
CONCENTRATE (drain - black tubing), and FEED (inlet - white tubing). Install the provided
white tubing to FEED port for inlet water. Install a red clip (included in system parts bag) on
FEED port to lock tubing in place. Install other end of white FEED line to tap/source water,
or use included garden hose connector (included in system parts bag).
Refer to page 4 for quick-release port instructions.
2. The open end of the pre-installed ½” black tubing labeled “Flush” (B) goes to a drain.
Now you can begin to slowly turn on the water supply and flush the dust from the carbon
pre-filter, until water stream is clear (approx. 5 min).
3. Turn OFF the water supply and immediately turn it ON again, to create an aggitated flush
effect in the carbon cartridge. Repeat this process 3 –4 times or until there are no carbon
fines in the water stream.
4. Install System Tubing for Normal Operation: Remove red clip (A), disconnect ½” black
Flush tubing (B) and then push system tubing (C) into carbon pre-filter port. Replace the
red clip to lock system tubing to carbon pre-filter, shown in the picture below. For filter
replacements, reverse this step.
IMPORTANT: Keep black Flush tubing for future carbon pre-filter flush procedures.
