FR2 models. Units equipped with Auto-Fill require the following

steps before startup.

WARNING

ELECTRIC SHOCK HAzARD:

• Unit must be installed by qualified, trained installers.

Installation must conform to all local electrical and

plumbing codes. Installation by unqualified personnel

will void the unit warranty and may lead to electric

shock or burn, as well as damage to unit and/or its

surroundings. Check with local plumbing and electrical

inspectors for proper procedures and codes.

• Turn OFF power switch, turn off power at circuit

breaker, and allow unit to cool before performing any

cleaning, adjustments, or maintenance.

Auto-Fill units must be installed with adequate backflow

protection and must conform with all federal, state, and

local codes.

NOTICE

Do not exceed an incoming water temperature of 140°F

(60°C) or incoming water pressure of 80 psi (550 kPa).

1. Make sure the POWER ON/OFF (I/O) switch is in the off

position and power is off at the circuit breaker.

2. Connect 1/4" NPT copper water supply line to the water

inlet of the solenoid valve near the back of the unit.

or other anti-siphon device must be supplied by table

holding vessel for the water level sensor to be installed.

• Install the sensor in the sink or holding vessel at least

1/2" (13 mm) below any food pans or other object it

could come into contact with. Incidental contact may

cause false readings and damage.

• Make sure the sensor is easily accessible for cleaning.

4. Mark and drill a 1/2" (13 mm) mounting hole into the side

wall of the sink or holding vessel.

5. Deburr the hole to prevent burrs from cracking or damaging

the probe when tightened.

level sensor.

7. Position the water level sensor into the sink or holding

vessel making sure the o-ring is in place on the sensor

against the inside wall.

on the outside wall of the sink/holding vessel.
