Frequency of Starts and Stops
Check pump cycling frequency and make sure that the
pump is not starting more than:
Frost Protection
1. If you do not use your pump during seasons of
frost, drain it and add a glycol based antifreeze
(50/50 mixture) to avoid damage.
Risk of flooding. Can cause personal injury
and/or property damage. Watch the direction of the
priming plug and make sure that liquid escaping from
it does not injure persons nearby or damage the motor
or other components. In hot water installations, pay
particular attention to the risk of injury from scalding
hot water.
2. Upon restart dispose of spent antifreeze properly.
3. Do not replace the drain plug or tighten the priming
plug until you put the pump back in service again.
Regular Maintenance Checks
The following checks should be made at regular intervals:
1. The pump meets required performance and is
operating smoothly and quietly.
2. There are no leaks.
3. The motor is not overheating.
4. Remove and clean all strainers and filters in the
system.
5. Verify amp draw – check motor amperage.
6. Pump wear rings and shaft require no regular
maintenance.
