NOTICE

Filter cartridges should be changed at end of filter life, due to lack of
filtering performance, or whenever a 15 psi pressure drop or greater
is experienced during normal operation, whichever comes first.

For all replacement filters and components contact your authorized
Hydro-Safe Foodservice representative.

*The QTCM15S, QTCM20S and QTCMX20S are the same filters as the
QTCM15, QTCM20 and QTCMX20 respectively. Only the label position has
been changed so that the label faces forward on single cartridge systems.

Notice to Installer

• Do not discard this manual after installation. This manual contains

important operation, maintenance and precautionary information.
Please present this manual to the user/owner/operator after
installation.

• It is strongly suggested that you read this manual before installing

system to ensure the best possible installation.

• Installation must comply with all local and state plumbing codes

and regulations.

• Connect the system to cold water supply only. Water Temperature

cannot exceed 100°F (38°C).

2

• System must be installed in a vertical, upright and level position.

• Do not use with water that is microbiologically unsafe or of

unknown water quality.

Installation Precautions

• Do not install system on line pressure above the rated pressure as

noted in System Specications above.

• Do not install the system on a hot water line. Failure to limit the

water temperature to 100°F (38°C) can result in housing failure and
property damage.

• Do not connect the system backwards with the feed water line

connected to the outlet.

• Do not use liquid pipe thread compounds for threaded
connections. Use Teon

• Do not solder plumbing connections that are attached to the
housings or inlet/outlet ttings. System damage may occur due to
high temperature.

• Do not allow the system to freeze. Turn off water supply and drain

the system if temperature falls below 32°F (0°C).

• Do not install system in direct sunlight or where the system will be

exposed to harsh chemicals or may be subjected to being hit by
moving equipment, carts, mops, or any other item that may cause
damage.

• Allow 3" (76mm) minimum clearance under the housings for lter

replacement.

• If water hammer is evident, install water hammer arrestors before

the system.

• Do not over tighten tting connections.

• Always back up valves and ttings with a wrench when installing

ttings to avoid over tightening or loosening existing ttings.

• Do not install the unit behind equipment where it may be difcult to

access the system for future lter replacements.

Position the system in a suitable location. The direction of ow
through the system is left to right. Keep this in mind when determin­ing installation locations. Do not mount the system near any source
of heat. Also do not mount this system over anything that may be
adversely affected by water.

®

tape only.

Operation

With sufcient pressure, operation of this system is completely auto­matic. Dependable operation involves only monitoring system pres­sure differential, periodic lter changes, and service documentation.

Installation

NOTICE

There is some light eld assembly required for this system.
Before beginning the installation of this system, please make
sure all components are present. Compare the contents of this
box to the system drawings located at the end of this manual.
As illustrated by the drawings, not all systems utilize pressure
gauges. These drawings will be referenced in the installation
instruction steps.

1. Turn off all equipment to be fed by the system, locate the water

supply shutoff valve and turn it off.

2. Apply Teflon tape to the threads of the inlet and outlet valve assemblies
and pressure gauges (if supplied for your model). DO NOT USE PASTE
TYPE THREAD SEALANT. Thread the inlet and outlet valve assemblies
into the inlet and outlet ports of the system as shown on the system
drawings in this manual. Install the pressure gauges, if applicable, into
the gauge ports as indicated by the system drawings in this manual.

NOTICE

DO NOT OVER TIGHTEN THESE FITTINGS INTO THE FILTER HEADS.

When installing fittings onto this system, back any existing receiving fittings
with a wrench to prevent fitting movement. Use a wrench to tighten gauges
into their connection ports. Do not twist on gauge case.

3.

Install the filters into the filter manifold. Make sure all plastic wrapping
and protective plastic caps have been removed from the filters prior to
their installation. Insert the prefilter into its blue canister. Make sure the
blue canister's oring is properly inserted into its oring groove. Thread the
housing onto the head with standard clockwise rotation (when viewed
from below). Hand tighten the blue housing (Not all systems will have
a blue prefilter. See the system drawings in this manual for proper filter
placement). Then install the QT style filter cartridges. To install these
filters, push them into the heads and give them a quarter twist (clockwise
when viewed from below). When the filter is completely inserted, the
cartridge label will be front centered.

4. Anchor the system on a wall stud or suitable mounting material
spanning wall studs. System must be vertical, upright and
level. The mounting hardware used must be selected and
installed so that the system is rmly pressed against the
mounting surface. The system mounting hardware must keep
the system from moving during routine service and operation.

5. Run a suitable line from the tap water source to the inlet ball
valve on the left side of the system. Brace the inlet ball valve on
the system with a wrench when connecting the feed water line.

NOTICE

DO NOT OVERTIGHTEN CONNECTION FITTING INTO
BALL VALVE.

6. Select the appropriate size tubing for the equipment being fed,

and connect it to the outlet ball valve of the system.

NOTICE

DO NOT OVERTIGHTEN CONNECTION FITTING INTO BALL
VALVE.

7. Install the ¼" (8mm) tubing into the Quick-Connect tting on the
outlet of the system and hold it over a drain. Open the
drain valve.

8. Once all inlet and outlet piping has been completed, check and
make sure all lter housing(s) are tight, slowly open the inlet valve
and allow all air to purge from the system through the 1/4"
tubing. Slowly close the
to reach operating pressure, and check for leaks.

9. If no leaks are present, open the
allow it to run to drain for 5 minutes to ush the system. Then
close the valve.

10. Open the outlet water valve and check for leaks.

11. Record the start up date and pressure gauge values in system
maintenance log.

NOTICE

Overtightening components can damage the system causing
water damage and/or system failure.

Maintenance

Routine maintenance of this system involves periodic lter changes.

Filter cartridges should be changed at end of lter life, due to lack of
ltering performance, or whenever a 15 psi pressure drop or greater
is experienced during normal operation, whichever comes rst.

Filter Cartridge Replacement Procedure

!

WARNING

Determine whether all equipment connected to the system must
be turned off prior to shutting off water supply from lters.

1. If required, turn off downstream equipment.

2. Turn OFF water to the system by closing the inlet and outlet ball
valves.

3. Open the ¼" drain valve on the outlet of the system to relieve
pressure in the housings.

Remove all filters. The blue prefilter housing unscrews to the left when

4.
viewed from underneath. It has a standard right hand thread. The QT
style filters are removed by rotating them 1/4 turn to the left and then
gently pulling down.

3

5. Clean inside of blue housing sump with warm water. If desired,
disinfect housing using a teaspoon of household bleach. Add
to lter bowl and ll with water. Let stand 5 minutes and then
discard and rinse.

6. Insert new QT style lters into the manifold assembly. Push up
and twist each QT cartridge 1/4 turn to the right to properly
install it into the manifold assembly. When making the 1/4 turn,
the cartridge label should come to a stop facing you.

Insert a new prefilter cartridge into the blue prefilter housing. Check

7.
O-ring for damage and replace if damaged or distorted. Make certain
the O-ring is properly positioned and reinstall the filter housing. Tighten
housings hand tight.

Do not overtighten lter housing, overtightening may damage
O-ring(s), cause water leaks, or affect system performance.

8. Slightly open the inlet ball valve and fully open the ¼" drain
valve. Once full ow of water ows from the drain port, slowly
open the inlet valve to the full open position. Allow water to ush
to drain for 5 minutes.

9. Slowly close the drain valve and check the system for leaks.

10. Slowly open the outlet valve to restore water ow to downstream
equipment.

11. Record lter change date in system maintenance log.
