REPAIR KITS (Repair Kit Parts)
What to look for if:
• The flow of water is less than desired.
a. Stop valves or supply to Hydroguard not fully open.
b. Clogged checkstop strainer screens.
c. Accumulation of lime deposits around valve seats.
d. Low supply pressures or unusual supply temperatures.
• The flow of water is completely shut off.
a. Stop valves or supply valves are completely closed.
b. Valves downstream from Hydroguard fully closed.
c. Loss of either hot or cold water supply pressure.
• Discharge temperature varies:
a. Very large restriction in outlet flow.
b. Very large drop in inlet pressure.
c. Very large fluctuation of hot water supply temperature.
d. Worn valve seats.
e. Minimum flow requirement not achieved.
MAINTENANCE AND TROUBLESHOOTING
1. IMPORTANT: Flush all piping thoroughly before installing.
2. Valve should be installed close to the hot water supply and
should easily be adjusted and repaired.
3. Remove body screws to turn outlet to any of four positions.
The Hydroguard body can be rotated to any position due to
the union inlets. Note: Make certain the body screws and
unions are tightened securely to prevent leakage.
4. CAUTION: When the Hydroguard supplies tempered water
to self-closing and/or solenoid valves, provide a shock
absorber (Powers Part No. 460-353) on the discharge line.
This protects the Hydroguard thermostatic motor from dam-
age by water shock waves generated by the quick closing
valves.
5. Before use, check maximum discharge temperature.
Reset if necessary.
OPERATION CHECK:
After Hydroguard is installed, make certain the supply stop
valves and strainers are free and clean and ready for operation
by disassembling checkstops as shown in "Servicing", steps 1,
2, and 3.
