DRAINING INSTRUCTIONS
WARNING!
WL500 WATER TREATMENT SYSTEM
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 3 tanks and a booster pump circuit that must be drained in the
WL500 Water Treatment
System
. The cold still water circuit of the
WL500
Water Treatment System
consists of a 2‐liter Cold
Tank, a 1‐liter pre‐chill chamber and a booster pump circuit that is sealed and must be vented to drain.
The booster pump will have some water in the circuit that must be purged to remove it. The Sparkling
Chamber does not have a vent or drain port and must be dispensed until empty (pushing CO
2
gas only
out of the faucet) to clear the water from the Sparkling Chamber. It is critical to clear the cold still
water before draining the Sparkling Chamber to ensure the pump does not inject water back into the
Sparkling Chamber. The Hot Tank has a drain port and is the only tank that is open to atmosphere
through the vent and faucet.
Prior to draining the Hot Tank, turn the GREEN Compressor/Heater Switch off
(
O=OFF
), and dispense 2 liters of hot water from the machine. As hot water is
dispensed from the faucet of the unit, colder water will be introduced into the Hot
Tank. Since the GREEN Compressor/Heater 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.
Disable Cold and Hot Tanks
1.
Turn off the GREEN Heater / Compressor Switch to disable the heater and
Compressor.
O=OFF
2.
Dispense 2 liters of water through the Hot Tank to cool the water temperature in
the Hot Tank and avoid burns.
WARNING!
VERY HOT WATER CAN BURN OR SCALD.
Hot water should be dispensed carefully into insulated container to avoid injury.
Turn off Water Supply and Bleed Water Pressure
3.
Isolate the unit from feed water by turning off the supply.
4.
Dispense cold still water to relieve any pressure built up in the system.
5.
Remove the water supply line from the unit.
6.
Install dust cap or plug into water supply line bulkhead fitting.
