INSTALLATION (continued)
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 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 in this
manual.
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. 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.
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.
Fig. 3 1/4 Turn Ball Valve
Installation of a PRESSURE REGULATOR and WATER HAMMER
ARRESTOR (to be provided by plumbing installer) on the incoming
water line is recommended.
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.

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:
shipped from the factory configured for either 208 volt or 240 volt use.
It may be converted from 208 volt to 240 volt, or from 240 volt to 208
volt, use by moving 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.
SHOCK HAZARD
Failure to connect the chassis

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.
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 resistance at connector on tank: L1 to L2 = 144Ω (5 gal).

OPERATIONAL NOTES
Water-Max™ will not operate if water pressure is less than 25 p.s.i. If Water-Max™ 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-Max™.
ERROR CODES are displayed on the control board readout, visible through the view port on the upper
right side of the dispenser. Refer to Water-Max™ Service Manual p/n 503364 for error code meanings
and suggested remedies.
There are no user serviceable components in the appliance. In all cases of damage or component
malfunction, contact your Authorized Wells Service Agency for repairs.
