Draining Notes
Drain the WL350 Water Treatment System for transportation.
WARNING!
STORE UNIT EMPTY. ALWAYS SANITIZE BEFORE REUSE.
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 WL350 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.
