WL7 FW INSTALLATION PROCEDURES
6.
Follow instructions on the screen. The
WL7 FW
will instruct installer to hold the dispense button
until a steady stream of water is flowing to the faucet. This fills the Hot Tank.
7.
The installer should then turn ON the Heater/Compressor (Green) Switch.
8.
The
WL7 FW
will now be in
Operational Mode
with both switches in the ON
position and the home screen will appear on the display.
9.
Dispense cold into container until steady stream of water is
present to remove any trapped air from the circuit and repeat for the
ambient (room temperature) circuit.
10.
Connect 3 Bar (42.5 psi) supply of food grade CO
2
to the CO
2
inlet bulkhead fitting on the back of
the unit. Dispense sparkling water until only gas is flowing to the faucet to purge the system of
trapped air. WL7 FW should automatically refill the carbonator in approximately 30 seconds once
the dispense button is released. The injection pump will turn on 2 seconds after releasing
sparkling dispense button. Premium Sparkling Water will not be produced until the system has
reach cold set point.
11.
It will take the heater approximately 10 minutes to heat the water to the factory set point of 87°C
(187°F). The hot status bar will flush when heater is on and be solid with heater off. The hot
status bar arrows indicate tank temperature
from
below 40°C (104°F) on far left to set
point on the far right.
Dispense a cup of hot water to ensure the
temperature/odor/taste is acceptable.
WARNING!
HOT WATER CAN BURN OR SCALD.
The
WL7 FW Water Purification System
produces Hot Water up to 95°C (203°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.
12.
Once the
WL7 FW Water Purification System
ice bath builds a complete ice ring in approximately
90 minutes depending upon environment. The compressor will shut off once the ice ring has
reached thickness ice sensor.
The cold status bar will flush when
compressor is on and be solid with
compressor off.
You can visually inspect the ice ring
build
through the access hole in the top of the ice bath if needed. The condenser at the rear of the unit
will build heat as indication the refrigeration system is operating properly. Route all hose away
from direct contract with heat from the condensing coils at the back of the unit.
