SECTION 4 - SERVICE Page S4-4
WINTERIZATION
1. Winterize pool with air as you normally would. Make sure that power is
off and the pump is disconnected.
2. Blow air through the PCS1 pipes until all water is removed.
3. Perform all other winterization chores.
4. Make sure all pipes by support system are drained completely or they will
freeze and bust. Any suspect pipes having ÒtrappedÓ water should have a hole
drilled and a plug installed for winter draining.
5. Remove the PCS1Õs outlet union [at bottom of coil]. Tilt the opposite side
up two inches and drain any coil water into a pan. Next, tilt the inlet/outlet side up
two inches followed by a second tilt of the opposite side for draining any additional
coil water into the pan. Repeat this process until no water drains from the PCS1.
6. Pour 1 quart to 1/2 gallon of RV [recreational vehicle] non toxic antifreeze
into the bottom of the PCS1. Note: This dilutes any residual ÒtrappedÓ water still
remaining within the coil and insures no freeze damage. This is the same type of
antifreeze used in the poolÕs pump and skimmers during the winterization process!
7. Reinstall the outlet union.
8. The PCS1 is winterized.
CAUTION
Failure to follow Step #6 above can lead to water coil damage! Even after Steps #1-5,
the PCS1 water coil could still retain a small amount of residual water that is
ÒtrappedÓ within the bottom of the coil. The non-toxic ÒRVÓ antifreeze [available at
local hardware stores] dilutes any residual water and prevents winter freeze damage.
