11. Solenoid Control Box – CHECKED
COLD WEATHER OPERATION AND STORAGE
Ice will cause serious damage to water pump, spray
heads, butterfly valves, water-to-oil cooler, and the
water cannon if water is allowed to freeze in the
volute case, water piping, or on top of a closed
butterfly valve. Ensure all water is drained from
system when the temperatures are expected to fall
below 4.4°C (40°F) 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, spray bars,
etc.).
