Storage; Preparing For Storage; Removing From Storage - North Star 157145 Owner's Manual

When not in use, store the pump indoors.
For long term or winter storage, prepare the pump by running RV antifreeze (DO NOT use
automotive antifreeze) through the system. This will keep internal parts lubricated, protect against
corrosion, and keep the unit from freezing.
The pump will be damaged if it freezes.
Protect the pump from freezing during storage by following the instructions below.

Preparing for storage:

1. Flush with
water
2. Add antifreeze
3. Spray briefly

Removing from storage:

1. Drain
2. Flush with
water
3. Disposal
CAUTION
Fill the pump system with fresh water and run through the system. Operate
the pump system until the system is completely flushed.
DO NOT add antifreeze before flushing the system as bleach can react
with antifreeze.
Pour RV antifreeze (DO NOT use automotive antifreeze) into the pump
system.
Note: RV antifreeze is non-toxic and biodegradable and generally safer for
the environment than automotive antifreeze.
Turn on the pump and run the pump system briefly until fluid sprays.
Drain the antifreeze left in the pump system into a suitable container.
Fill the pump system with fresh water and run through the system. Operate
the pump system until the system is completely flushed. Be sure to set up
containers to capture the antifreeze flush water.
Dispose of the antifreeze and flush water properly.
