11. Solenoid Control Box – CHECKED
COLD WEATHER OPERATION AND STORAGE
Ice will cause serious damage to water pump, spray
heads, butterfly valves and the monitor if water is
allowed to remain in the volute case, water piping or
on top of a closed butterfly valve and freeze. Ensure
all water is drained from system when the
temperatures are expected to fall below freezing for
any period of time. Failure to ensure all systems are
drained and free from standing water will result in
shaft, operator, diaphragm, drive motor, water pump
or butterfly valve damage when operation is
attempted with ice in the housings.
To ensure all water is drained from tank check the
following;
1. Park unit on a slight nose up angle to allow water
to flow to the rear of the tank.
2. Drain the tank using an appropriate method until
the Water Level Gauge reads EMPTY.
3. Open all drain petcocks (water pump, suction
load pump, rear spray bar, front spray bar, etc.).
