INSTALLATION AND OPERATION MANUAL
PAC HEAT RECOVERY WATER HEATER
Maintenance
In order to achieve the maximum life from your PAC Fre-Heaters the following
should be done annually:
1.
Remove and check at least one of the two anode rods. Both anode
rods should be replaced
2.
Check the operation of the pressure/temperature relief valve by
manually operating it to see that it will freely flow water should it be
required to do so. If there is any doubt that it will not function
properly, replace it.
3.
Check all water fittings, valves, etc. to be sure there are no water
leaks. Repair as necessary.
4.
Check the operation of all controls such as the hot gas bypass valve
aquastat, electric element controls, refrigeration head pressure
controls, or any other controls necessary for the proper operation of
the Fre-Heater and the refrigeration and/or air conditioning systems it
is connected to.
