Winterizing - STA-RITE S7MD60 Owner's Manual

NOTICE
The filter outlet piping will not empty
through the filter drain. Make sure that
the outlet piping has a separate drain for

winterizing.

WINTERIZING
Explosion hazard. Purging the system with compressed air can
cause components to explode, with risk of severe injury or death to anyone
nearby. Use only a low pressure (below 5 PSI), high volume blower when air
purging the pump, filter, or piping.
NOTICE: Protect the filter from freezing. Allowing the filter to freeze will dam-
age it and will void the warranty.
1. Clean the filter according to instructions (Page 10) before winterizing. Do
not winterize with DE precoat on cartridge or with residual in tank.
2. Stop the pump.
3. Open the air release valve; open all the system valves.
4. Remove the drain plugs from the trap, pump, and filter.
5. Drain the system piping.
A. Gravity drain system as far as possible.
B. Protect areas which retain water with non-toxic propylene glycol
antifreeze ("RV antifreeze").
6. Loosen the union nuts (if used) to drain all water from the filter interior.
Leave these nuts loose until the system is restarted.
7. Disassemble the filter (follow instructions under "Filter Disassembly", Page
8). Remove the filter module and store it in a warm, dry area. Be sure to
store the cartridge where it will not be in sunlight.
8. Be sure to allow any water trapped in the tank to drain out.
9. Cover the filter with plastic or tarpaulin to prevent water entrance and
freezing.
