Water Isolation Valves and Flush Ports -
Water isolation
valves provide isolation to the unit for maintenance and
cleaning of load and source heat exchangers. Optional
motorized valves includes ¾” fill and flush valves.
Motorized source water valve provide head pressure
regulation for low entering condenser water temperature
applications (less than 60°F), in cooling. This is required
for units intended for both heating and cooling, optional
for other applications. Motorized Load water valve is
optional, would be required for variable speed pumping.
FIELD INSTALLED OPTIONS
Strainer Installation Instructions
1. Ensure all machined surfaces are free of defects and
that the inside of the strainer is free of foreign objects.
2. The strainer should be installed so that the drain
connection is pointed downwards.
3.
For flanged end strainers the flange bolting should
be tightened gradually in a back and forth clockwise
motion. Threaded end strainers should use an
appropriate sealant.
4. Once installed increase line pressure gradually and
check for leakage around joints.
5. If the strainer is supplied with a start-up screen
monitor pressure drop carefully.
6. Isolation valves should be installed for ease of
maintenance of strainers.
IMPORTANT: Ultimate responsibility for strainer and
material selection rest with the end-user or facility
manager, as only the end-user or facility manager
knows the particular application and operating
parameters to which the strainer will be subjected.
ClimateMaster recommends basket type for Source side.

CAUTION!
⚠
CAUTION!
Prior to dismantling the strainer for cleaning,
it is imperative that the strainer assembly is isolated and
completely de-pressurized.
CAUTION!
Caution should be taken due to possible emission
of process material from piping. Always ensure no line
pressure exists when opening cover
Strainer Removal Instructions
Y Type Strainers:
1. Drain piping.
2. Vent line to relieve pressure.
3. Loosen flange bolts (flanged ends).
4. Secure necessary lifting equipment to strainer assembly.
5. Remove inlet/outlet flange bolts (flanged end), or
unthread (threaded ends) and carefully remove strainer.
6. Tighten cover. The strainer is ready for line start-up.
Basket Type Strainers
1. Drain Piping.
2. Vent line to relieve pressure.
3. Loosen cover and open to access basket.
4. Remove, clean and replace basket in original position.
(Note: In some instances a high pressure water jet or
steam may be required for effective cleaning).
5. Inspect cover gasket for damage. If necessary replace.
(Note: If spiral wound gaskets have been used, they
must be replaced and cannot be used again).
6. Tighten cover. The strainer is ready for line start-up.
Maintenance Instructions -
For maximum efficiency
determine the length of time it takes for the pressure drop
to double that in the clean condition. Once the pressure
drop reaches an unacceptable value, shut down line and
follow the Strainer Removal Instructions above.
A pressure gauge installed before and after the strainer
in-line will indicate pressure loss due to clogging and may
be used to determine when cleaning is required.
Troubleshooting Guides and Diagnostic Techniques
-
After pressurizing inspect cover and other joints for
leakage. Gasket replacement or cover tightening is
necessary if leakage occurs. If the required filtration is not
taking place, ensure the screen is installed in the correct
position, and that the screen is mounted flush to the
upper and lower seating surfaces.
