SETUP
Verify that this dispenser installation is in compliance with the
specifications listed in this manual and with local code requirements.
THIS IS THE RESPONSIBILITY OF THE INSTALLER.
Recommended height of the faucet is 38” to 42” above the floor.
However, the actual installed height will vary with the requirements of the
individual store.
Install temperature gauge in water tank. Install plastic holding nut hand
tight only. Refer to exploded view, page 23.
For countertop installation
The counter at the installation location must be level, provide a
clear space at least 17-1/2”” deep and must be structurally capable
of safely supporting 150 pounds.
Set Water-Max™ on its back. Install the AIR OUTLET GUARD.
Guard is positioned on the bottom of Water-Max™, fully to the rear,
with the open portion toward the front. Install the REAR LEGS to
hold the guard in place.
Install the FRONT LEGS. Make certain all four legs have the
RUBBER FEET installed. Set Water-Max™ upright on the counter.
With the dispenser in its final installed location, adjust for level with
the adjustable legs. With a spirit level, check and adjust the
dispenser for level front-to-rear and side-to-side.

INSTALLATION (continued)
IMPORTANT INSTALLATION NOTICE
Installer will be required to test water pressure, water flow, water total
hardness, electrical voltage and amperage; and to record dispenser
installation particulars on the INSTALLATION CHECK OUT form (see
page 9).
PLUMBING LINE CONNECTION
If power has been run to the dispenser, verify that the circuit breaker is
turned OFF, and that the power switch is in the OFF [O] position.
Water-Max™ has an internal sensor to verify that there is sufficient
water pressure to operate. Water-Max™ will not operate until a water
supply is connected to the unit or if water pressure is less than 25 p.s.i.
Water-Max™ must be connected to a potable water supply.
NOTICE:
WATER PIPE CONNECTIONS AND FIXTURES DIRECTLY
CONNECTED TO A POTABLE WATER SUPPLY SHALL BE SIZED,
INSTALLED AND MAINTAINED ACCORDING TO FEDERAL, STATE,
AND LOCAL ORDINANCES.
May be connected to either hot or cold water line. Temperature of a
hot water line must not exceed 140ºF.
DO NOT use a saddle valve to connect Water-Max™ to main supply
line. Connecting to a hot water line will increase the volume flow of the
dispenser.
Minimum 1/4” copper or flex tubing supply line (3/8” minimum if run
from main supply exceeds 12 feet) with 1/4” female flare fitting. Water
line material must be rated for at least 180ºF.
Minimum 25 psi / maximum 75 psi water pressure at full flow.
The installation of a SHUTOFF VALVE (must be provided by plumbing
installer) on the incoming water line is required. A 1/4 turn ball valve is
recommended to minimize restricting the water flow during operation.
DO NOT use a saddle valve to connect Water-Max™ to main supply
line.
Clean the incoming waterline: Run water through the line into a sink or
bucket to flush any foreign particles or debris from the waterline.
Assemble incoming water line to the inlet fitting. Turn on water supply
valve and check for leaks.
Test water for pressure at full flow. If a pressure regulator is installed,
adjust pressure to 40 p.s.i. Record this reading on the INSTALLATION
CHECK OUT form.
Test water for total hardness. Record readings on the INSTALLATION
CHECK OUT form.
CAUTION:
Risk of Damage
DO NOT connect or energize
this appliance until all Installation
Instructions are read and followed.
Damage to the dispenser will
occur if these instructions are
not followed.
IMPORTANT: Water supply
MUST be a minimum of 1/4”
line, and MUST be capable of
supplying 25 p.s.i. AT ALL
TIMES during the operation of
the dispenser.
IMPORTANT: Water line
material must be rated for at
least 180ºF.

ELECTRICAL INSTALLATION
NOTICE:
A DEDICATED CIRCUIT OF AT LEAST 50 AMPS IS REQUIRED.
WIRING MUST BE AT LEAST 6 ga., SUITABLE FOR 75º C.
CONDUIT, WIRING AND CONNECTIONS MUST BE INSTALLED
AND MAINTAINED IN COMPLIANCE WITH
FEDERAL, STATE, AND LOCAL ORDINANCES.
Conduit, wiring and connections must comply with the specifications in
this manual, and with local ordinances. A 208V or 240V single phase,
50 amp circuit required.
Field supply wiring must pass thru, and be secured by, the strain relief
on the bottom left side of the dispenser.
Field wiring supply power must connect to the rear-most side of the
terminal block, terminals L1 and L2 as shown in Fig. 4.
NOTE: Terminal block is accessible by removing the tank shelf.
Remove the two screws under the shelf and lift the shelf off of the unit.
See wiring tag.
The dispenser is shipped with red wire #11 unattached. Configure the
dispenser for either 208 volt or 240 volt use:
Determine input voltage.
READ CAUTION TAG. Remove tag and wire nut from wire #11.
Attach wire #11 to either the terminal labeled “208V”, or to the
terminal labeled “240V”, as appropriate for the input voltage.
Optional cord set uses a 4’ cord and NEMA 6-50P plug (see Fig. 5).
A suitable earth ground must be connected to the ground lug located to
the left of the terminal block (see Fig. 4. above).
Check all connections to terminal block for tightness.
Test electrical supply for voltage and amp draw while unit is filling water
tank. Record readings on the INSTALLATION CHECKOUT form.
Upon completion of the electrical hook-up and testing, properly reinstall
all panels.
Fig. 4 Terminal Block Wiring
CAUTION:
SHOCK HAZARD
Removal of any exterior panel
will result in exposed electrical
circuits. Electrical connection
must be performed by a
qualified technician only.
Use care whenever working
around exposed electrical
circuits.
IMPORTANT:
Contact a licensed electrician
to install and connect
electrical power to the
dispenser.
IMPORTANT:
Damage due to being
connected to the wrong
voltage or phase is NOT
covered by warranty.
IMPORTANT:
Field wiring supply voltage
must correspond to the
position of red wire #11
(i.e. 208V or 240V). Failure to
match wire #11 position to
input voltage can result in
equipment damage or reduced
performance.
Such damage is not covered
by warranty.
CAUTION:
SHOCK HAZARD
Failure to connect the chassis
ground to a suitable earth
ground will result in a potential
shock hazard.

(Check Error Code in View Port)
a. Possible cause; sufficient inlet water pressure is not sensed during
tank filling:
Be sure water supply is adequate during all phases of operation.
Other equipment on the water line may be robbing water volume
and/or pressure from Water-Max™. Also, be sure any supply line
filters are clean.
b. Possible cause; sufficient temperature rise is not sensed between
inlet and output water while tank is filling:
Be sure electrical supply voltage remains at rated value during all
phases of operation. Otherwise, refer to Service Instructions, page
16.
Water-Max™ will not flow water from the dispense nozzle.
a. Verify that power indicator is lit, and status indicator is not flashing.
Check that tank is properly positioned and that the tank indicator is
lit.
b. Verify that the water tank is in place holding the tank position
momentary switch ON;.
c. Verify that the water level is below the water level sensor. If water
level is low, verify that the water level sensor and surrounding area
are clean and free from lime and scale. To clean, drain and remove
tank. Remove lid. Clean around probe then reinstall lid on tank
and tank on Water-Max™. See Cleaning Instructions, page 15.
The water tank heater will not heat:
a. Verify the water tank connector is fully mated with the receptacle.
The tank indicator will glow when the tank is properly installed.
b. Verify power switch is ON.
c. Check ohms at connector on tank: L1 to L2 = 144Ω

OPERATIONAL NOTES
Water-MaxTM will not operate if water pressure is less than 25 p.s.i. If Water-MaxTM shuts down (status light flashes)
for no apparent reason, other equipment on the water line may be robbing water pressure and/or volume from
Water-MaxTM.
ERROR CODES are displayed on the control board readout, visible through the view port on the upper right side of
the dispenser. To reset error code:
•Turn Power OFF. Wait 20 seconds
•Turn power ON.
•If error code does not reset, contact the National Service Cooperative at 1-800-298-1862 for the Wells
Authorized Service Agency nearest you.
