Winterizing the System

1. In areas that have freezing winter temperatures, protect the pool
equipment by backwashing the filter.
2. After backwashing, shut the pump off, open the manual air bleeder on
the valve and move the handle to "Winterize" position.
3. Remove the drain cap on the bottom of the filter. The filter will drain
very slowly. During the shutdown season, it is recommended to leave
the drain plug out.
4. Drain all water from the pump housing and piping when freezing
temperatures are expected. Remove both drain plugs from the pump to
allow the pump to drain completely.
5. If possible, remove the pump and place it in an inside dry location.
6. For an outdoor unprotected location it is best to protect the equipment
in a weather proof enclosure.
7. It is recommended to cover the equipment with a tarpaulin or plastic
sheet to prevent deterioration from the environment. DO NOT WRAP
THE PUMP MOTOR WITH PLASTIC, this will cause condensation
to form inside the motor.
8. In installations where the pump cannot be drained a 40% Propylene
Glycol 60% water solution will protect to -50° F (-45.5° C). Note: Do
not use anti-freeze solutions except Propylene Glycol; as other
anti-freeze are highly toxic and will damage the pump.
Pump and Sand Filter System Installation and User's Guide
Allowing water to freeze in the system will damage the
system and cause potential water damage/flooding and
potential property damage.
The control valve should be left in the "Winterize"
position during the shutdown season so that the
rubber seal of the valve diverter has no pressure
on it. Failure to do so can damage the valve
diverter seal which can cause property damage
from leaking water.
