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.
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.

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.
