CUBE DRAINING INSTRUCTIONS
WARNING!
CUBE IS A HEAVY OBJECT.
Use proper lifting aids and handling techniques to avoid injury. Use assistance as single person lift could
cause injury. Always drain before handling to reduce weight.
Draining Notes
There are 2 tanks and a booster pump circuit that must be drained in the
CUBE
. The booster pump will
have some water in the circuit that must be purged.
Prior to draining the hot tank, turn off both the
Green Heater/Compressor Switch and the Red
Power Switches located on back of the
Cube
and
dispense 2 liters of hot water from the machine.
I = ON, O= Off
As hot water is dispensed from the faucet of the unit, colder water will be introduced into the hot
tank. Since the Green Power Switch is turned off, the Heater will not energize and heat the incoming
tap water.
Following this precaution prevents exposing personnel and equipment (drains, catch basin, etc.) to
scalding hot water.
WARNING!
VERY HOT WATER CAN BURN OR SCALD.
Hot water should be dispensed carefully into insulated container to avoid injury.
