Safety Precautions:
• You must follow the guidelines to install this system. Check with your Province/State and local public works department for
plumbing and sanitation codes.
• If house water line pressure is over the maximum 100 psi (pounds per square inch), install a pressure regulator in the water
supply line before this system.
• System is for cold water use only and must be protected against freezing, which can damage the unit and cause water leakage.
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the
system. System certified for cyst reduction may be used on disinfected water that may contain filterable cysts.
• Make sure the water supply conforms to the specification guidelines. If the water supply conditions are unknown, consult your
local municipal water company or health department about the quality and the list of contaminants in your local water supply.
• When using the system for the first time, or after prolonged non-use (such as a vacation longer than one week), the system
should be flushed thoroughly.
• This system contains replaceable filter cartridges with a limited service life.

CAUTION: Do not drill through a countertop that is more than 1” thick.
CAUTION: Do not attempt to drill through a tiled, marble, granite or
similar countertop. Consult a plumber or the countertop manufacturer
for advice or assistance
CAUTION: When drilling through a countertop make sure the area
below the drilling area is free of wiring and piping. Make certain that
you have ample room to make the proper connection to the bottom of
the Faucet.
CAUTION: Do not attempt to drill through an all-porcelain or
porcelain-coated sink. For applications on these types of sinks we
recommend using the sprayer hole or mounting the Faucet through the
countertop. Otherwise consult a plumber or manufacturer for advice or
assistance.
1. Line the bottom of the sink with newspaper to prevent shavings, parts, or
tools from falling down the drain.
2. Place masking tape over the area to be drilled to help prevent scratches if
drill bit slips.
3. Mark point with a center punch. Use a 1/4” drill bit to drill a pilot hole.
4. Use a 1-1/4” hole saw to enlarge the hole. Smooth rough edges with a file.
Installation Instructions (continued):
1. Turn off the cold water supply by turning off the shut-off valve under the
sink. If the cold water line does not have a shut-off valve under the sink,
turn off the main water line in the house. Place a tray or towel under the cold
water line to catch any excess water.
2. Turn on the cold water faucet and allow all the water to drain from the line.
On a single handle faucet, the hot water may have to be turned off to prevent
any hot water cross over.
3. Loosen nut and separate cold water braided flex line from the kitchen cold
water faucet shank. Attach Inlet Valve to the faucet shank using the Rubber
Washer. Reinstall the flex line onto the Inlet Valve and tighten with an
adjustable wrench.
4. Insert 1/4” Tubing over the Guide Tube of the Inlet Valve. Tighten the
Compression Nut with an adjustable wrench.
CAUTION: The water supply to your unit MUST be from the
COLD WATER LINE. Hot water will damage your filtration system.
The Drinking Water Faucet should be positioned with function, convenience and
appearance in mind. An adequate flat area is required to allow the Faucet to rest
securely. Check the underside of the location for interference. Most sinks have
a pre-drilled 1-1/4" diameter hole designed for spray hoses. The Drinking Water
Faucet may be installed using this hole. If the pre-drilled hole cannot be used,
or is in an inconvenient location, it will be necessary to drill a 1-1/4” hole in the
sink or through the countertop next to the sink for the Faucet.

Installation Instructions (continued):
CAUTION: The use of an Air Gap Faucet is generally required by
plumbing code in US and Canada. Ensure installation meets all
necessary plumbing codes in your location. The Air Gap Faucet
will prevent waste water from contaminating the RO filters if there
is a blockage in the drain line.
1. Remove Stem Nut on the Faucet.
2. Slide the Chrome Plate and Black Rubber Washer onto the Faucet Stem.
3. Connect the 1/4” Black Drain Tube up to the 1/4” fitting on the Air Gap
Faucet.
4. Then connect the 3/8” Black Tubing to the 3/8” fitting on the Air Gap
Faucet.
5. The Chrome Plate, Rubber Washer and Faucet Body are installed above the
sink or countertop.
6. Feed the 3/8” and 1/4” Black Tubing through the pre-drilled hole in the
sink/counter.
7. Place the Faucet through the drilled faucet hole, then add Spacer,
Securing Plate, Star Lock Washer and Stem Nut.
8. Tighten Stem Nut firmly while aligning the Faucet in the desired location.
9. Gently slide Faucet Compression Nut down over the 1/4” Blue Tubing,
followed with the Ferrule. Then push the Insert into the end of the Tubing.
10. Firmly push the Tubing into the stem of Faucet until it stops. Hand-screw
the Compression Nut onto the threads of the stem. Tighten with a wrench.
NOTE: Make sure the tubing is pushed all the way to the end of the
fitting
NOTE: The 3/8” Black Drain Tube goes by gravity feed to the
Saddle Drain Clamp connection. Make sure there are no kinks,
loops, or sharp bends in the 3/8” black tubing. Failure to make a
straight line to the drain may result in reject water leaking through
the air gap in the faucet onto the countertop or below the faucet.

Installation Instructions (continued):
1. Attach the Saddle Drain Clamp to the vertical section of the drain pipe,
about 2 inches above the drain trap.
2. Using the fittings hole of the Saddle Drain Clamp as a guide, drill a 1/4”
hole through one side of the drainpipe.
CAUTION: Do not penetrate through the opposite side of the pipe.
3. Remove the Drain Clamp from the drainpipe and enlarge the hole with a
3/8” drill bit. Use a file to remove rough edges from the drilled hole.
4. Squarely cut the end of the 3/8" Black Tube. Insert the Tube through the
Saddle Drain Clamp quick-connect fitting about 1” past the inside wall of
the Saddle Drain Clamp.
5. Make sure the Black Rubber Gasket is adhered to the inside wall of the
Saddle Drain Clamp and place the Saddle Drain Clamp assembly over the
drainpipe. Insert 3/8” black tube into the drilled hole. Tighten the Clamp.
1. Position the RO unit on the back or right walls under the sink. Make sure to allow ample space for the installation and
plumbing connections. To change the filter cartridges, 2” of clearance is required underneath the filter housings.
2. Install mounting screws at least 15-3/4” from cabinet floor. Leave 1/4” space between the head of the screw and the wall
to slip bracket onto the screws. Then tighten the screws to secure the system.
Installing the Saddle Drain Clamp (See Figure 9 and 10):
Mounting the RO Unit Under the Sink:
CAUTION: Do not overtighten the screws, it may crack the Clamp.
CAUTION: The 3/8” Black Drain Tube must be as SHORT and
STRAIGHT as possible to the Saddle Drain Clamp, making a
downward slope from the faucet to the Saddle Drain Clamp to
allow for proper drainage. This is a gravity fed line and if there is
any bend or dip in the Tubing, the rinse water will not flow into the
drain properly. Water may back up and come out the Air Gap Hole
in the Faucet.

Installation Instructions (continued):
Periodic System Maintenance:
Start-up Instructions:
Install 1/4” polypropylene plastic tubing if your refrigerator is within 25 ft. of your RO unit. Do not use copper tubing for RO product
water. If the refrigerator is over 25 ft from the RO Unit it is recommended to use 3/8” tubing. Install a tee in the blue tubing
between the outlet of the system and the faucet. It is recommended to install a ball valve in the line to your ice maker to allow
pressure to increase sufficiently in the storage tank for the ice maker solenoid valve to operate properly. Leave the ball valve in the
closed position until the tank is full after the start-up procedure is completed.
Depending on which model was purchased the chart below will assist with replacement of filters. The replacement filter can be
obtained online at www.ghpgroupinc.com or at the retail store where the system was purchased.
NOTE: If you have connected your RO system to a refrigerator/ice maker, make sure the ice maker is off. Do not
allow water to flow to the ice maker until flush is complete and the tank has been allowed to fill completely.
Connection from the RO to the icemaker system should have an inline valve installed before the icemaker so it
can easily be closed to prevent water flowing to the ice maker during start-up and periodic maintenance.
Your RO tank must be allowed to fill up fully for the ice maker system to work properly.
NOTE: You will not have filtered water immediately. It will take 2 hours to
completely fill the Storage Tank to create liberal flow from the RO Faucet.
1. Turn Inlet Valve and Storage Tank Ball Valve both in open position.
2. Ensure the RO Faucet is closed.
3. Slowly open the cold water supply valve that you closed at the beginning
of the installation process.
4. Water pressure will start to build up in the RO system in about 2 hours as
pressure builds in the Storage Tank. Carefully inspect all Fittings and
Connections. Check for leaks and fix if any are found.
5. You must fill and purge a minimum of 2 tanks of RO water before it is ready
for consumption.
6. After purging, your RO system is ready for use.

Reverse Osmosis Drinking Water System
Model: PQC3RO, PQC4RO and PQC5RO
The system must be installed and operated in accordance with manufacturer’s recommended procedures and guidelines.
Failure to follow the instructions may result in leakage, malfunction and will void warranty.
Read the performance data (on page 16) and compare the capability of the system with your actual water treatment needs. It
is recommended that, before installing the system, you have your water supply tested to determine your actual water treatment
needs.
Arsenic Fact Sheet
This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V), As(+5) or Arsenate)
at concentration of 0.30 mg/L or less. The systems reduce pentavalent arsenic, but may not reduce other forms of arsenic. These
systems are also to be used on the water supplies containing a detectable free chlorine residual or own water supplies that have
been demonstrated to contain only pentavalent arsenic. Treatment with Chloramine (combined chlorine) is not sufficient to ensure
complete conversion of trivalent arsenic to pentavalent arsenic.
Arsenic is a naturally occurring contaminant found in many ground waters. There are two forms of arsenic: Pentavalent Arsenic
[also called as As(V), As(+5) or Arsenate] and Trivalent Arsenic [As (III), As (+3) and Arsenite]. Although both forms are potentially
harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic.
Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must have their water tested
for arsenic. You can get the results from your water utility. If you have your own well, you can have the water tested. The local
health department or state environmental health agency can provide a list of certified labs.
RO systems do not remove trivalent arsenic from water very well. RO systems are very effective at reducing pentavalent arsenic. If
you have free chlorine residual in contact with your water supply for at least one minute, the trivalent arsenic will be converted to
pentavalent arsenic and reduced by RO systems. Other water treatment chemicals, such as ozone and potassium permanganate,
will also change trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called chloramine) may not convert
all the trivalent arsenic. If you get your water from a public water utility, contact the utility to find out if free chlorine or combined
chlorine is used in the water system.
The system requires regular replacement of all filters to maintain proper operation. Depending on usage and influent water quality,
the sediment and carbon filters should be changed at least annually and the RO Membrane should be replaced every 2 years.
Variation of chlorine, sediment or TDS levels may affect replacement frequency.
