WL2FLT TOWER DRAINING INSTRUCTIONS
Draining Notes
Drain the WL2FLT Water Treatment System for transportation.
WARNING! STORE UNIT EMPTY. ALWAYS SANITIZE BEFORE USE, OR AFTER SYSTEM
FAILURE.
The unit must be completely drained and sealed before storing to avoid stagnation and reduce
microbial growth).
Prior to draining the Hot Tank, turn off the Red Heater and Compressor Power
Switch (O=OFF), and dispense 2 Liters (½ Gallons) of hot water from the machine.
As hot water is dispensed from the faucet of the WL2FLT Water Treatment System,
colder water will be introduced into the hot tank. Since the Red Heater and
Compressor 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.
Disable Cold and Hot Tanks
1. Turn off the Red Heater and Compressor Power Switch (O-OFF) to disable the
heater and compressor.
2. Dispense 2 liters (1 gallon) of water through the hot tank to cool the water
temperature in the hot tank and avoid burns.
WARNING! HOT WATER. The WL2FLT Water Treatment System produces Hot Water up to
84°C (187°F). Water above 52°C (125°F) can cause severe burns or scalding. Hot water should
be dispensed carefully into insulated container to avoid injury.
Turn off Water Supply and Bleed Water Pressure
3. Isolate the WL2FLT Water Treatment System from incoming feed water by turning off the supply.
4. Dispense cold still water to relieve any pressure built up in the system.
5. Prepare a drain line with a ¼” union that’s already routed to drain or catch basin. Disconnect the
line between the hot tank and the hot tank solenoid and quickly connect that line to the union of
the drain line set up earlier.
WARNING! As soon as the line between the hot tank and its solenoid is disconnect, water
will begin draining from the hot tank. Be prepared to pinch off the line or quickly swap it to
the drain line set up previously.
