WL400 FEATURES AND BENEFITS
Ambient, Cold, Hot, and Extra Hot Water
Pressure Fed Ambient, Cold, Hot, and Extra Hot Selections to meet a wide range of customer
demands. Cold water temperature is adjustable
High Volume Storage and Water Capacity
The WL400 has 4 liters of Cold Water Capacity and 1.2 Liters of Hot Water Capacity.
BioCote®Anti-Microbial Protection
Plastic surfaces surrounding dispensing areas and drip tray are infused with an
exclusive silver additive called BioCote®. Silver is a natural anti-microbial that
inhibits the growth of microorganisms providing additional surface protection.
Large Dispense Area with Recessed Faucet
8.5 inch dispense height with BioCote® recessed faucet to protect from cross-contamination.
Leak Detection
WL400’s are supplied with a Sensor in the Leak Tray that halts water supply to prevent overflow and
sounds alarm to reduce accident potential.
Energy Saving Sleep Mode
Energy saving Sleep Mode can be programmed to turn off heater after 3, 6 or 12 hours of inactivity
and can be shut off.
Firewall™
Firewall is proprietary technology that places the UV lamp at the point of
dispense. This point of dispense purification keeps the dispense nozzle free
from external contamination as well as purifying the water, making the
freshest water possible.

HOT TANK PRINCIPLES OF OPERATION
All Waterlogic Hot Tanks have a built in Vent or
Expansion Chamber in the top of the tank except for
WL270 (GF) units.
The Vent Chamber allows for expansion of the water
when it is heated.
The chambers are separated by a welded-in tank
baffle.
Water always flows into the bottom of the tank and
out the top to the faucet.
The hot tank outlet tube has a restrictor in its base.
This ensures the reservoir is always full by allowing
more water in than out.
There is a small hole in the side of the tank outlet tube
that allows air and water to pass into the vent
chamber as it is heated.
Water in the vent chamber is suctioned back through
the outlet tube vent hole when water is dispensed.
Expansion of water as it is heated in the reservoir will
push the water out the faucet when the outlet tube
vent hole becomes plugged with debris or scale.
The small Outlet Vent Hole is susceptible to scale build
up and is a key indicator that descaling is required.
It is critical to descale the hot tank through the vent
line and outlet line on a regular basis to prevent this
problem.
Descaling through the inlet and/or outlet lines only
will not clean the vent chamber and outlet vent hole
properly.

RO QUICK GUIDE
The WL400 contains a high capacity Reverse Osmosis Filtration System installed in the Base Cabinet.
Efficiency is improved by utilizing the on-board booster pump to optimize the osmotic pressure, and
a 4 Gallon Bladder Tank is included in the Base Cabinet.
The Filtration system has 4 Stages of Filtration with 100 Gallons per day capacity
combined with exclusive Firewall Purification.
Stage 1 – Sediment Filter; Removes unwanted particles and particulates down to 10 micron.
Stage 2 – Pre-Filter; Granular Filter removes unwanted chlorine, odor and bad taste
Stage 3 – RO Membrane; 0.001 Micron filtration to remove total dissolved solids from the water.
Stage 4 – Post Filter; Carbon “polishing filter” to improve the taste of the water.
Final Barrier – Firewall Advanced Water Purification; Acts as the Final Barrier at the Point of Use.

RO SETUP AND FILTER CHANGE INSTRUCTIONS
1. Remove Front Panel from Base Cabinet
2. Isolate Water Supply
3. Remove Pre-Carbon and Post-Carbon Filters and clear carbon fines by flushing 5 galls on
water through each filter individually to drain.
4. Reinstall Pre-Carbon and Post-Carbon filters.
5. Close RO bypass valve and bladder tank valve (See photo)
6. Flush RO Membrane to drain for a minimum of 4 hours or until TDS reduction is at desired
level (>90%). Water should be draining from both the water out line and drain line.
7. Open Bladder Tank Valve and turn on water supply. Ensure RO bypass valve stays in the
Closed Position.
8. Allow up to 1 hour for empty bladder tank to fill if necessary.
