Peak Dishwasher Performance for you.

Point Value

1. Time .................................................................................. 20

Wash and rinse times (set by NSF and Champion) allow
everything to work.

2. Temperature...................................................................... 20

Heated water penetrates and loosens soil on dishes.

3. Mechanical Action............................................................ 20

Pumps produce water pressure which flushes the soil off dishes.

4. Chemical Action ............................................................... 20

Detergent breaks down grease and loosens soil particles.

5. Procedure.......................................................................... 20

Pre-scraping and rinsing removes large food particles from the

Electrical Connections

WARNING:

Electrical and grounding connections must comply with the National Electrical Code and/or Local
Electrical Codes.

WARNING:

When working on the dishwasher, disconnect the electric service and place a tag at the disconnect
switch to indicate work is being done on that circuit.

1. A qualified electrician must compare the electrical power supply with the machine electrical
specifications stamped on the MACHINE ELECTRICAL CONNECTION PLATE located inside the
top mounted control cabinet before connecting to the incoming service at a fused disconnect switch.

2. Motor rotation was set at the factory. Check the rotation of the motor shaft (CW when viewed from rear
of motor). For three phase machines, reversing the motor direction is done in the control cabinet by
reversing the wires LI and L2 on the disconnect side of the main electrical connection block. For single
phase machines, motor rotation is changed at the motor connection plate on the rear of the single phase
motor.

Electrical Connections (cont'd)

3. A knock-out is provided at the rear of the top mounted control cabinet for the electrical service
connection. A single source electrical connection has been provided. A fused disconnect switch or
circuit breaker (supplied by others) is required to protect each power supply circuit.

Plumbing Connections

CAUTION:

Plumbing connections must comply with local sanitary and plumbing codes.

Water Connections

1. Connect the hot water supply to the "Y" strainer or pressure reducing valve (PRV) at the final rinse
piping (located behind the control cabinet at the top of the machine).

2. Minimum incoming water supply temperature requirements are listed below:

D-HB with built-in 40°F/23°C rise electric booster (Minimum 140°F/60°C) (Min./Max.
flow pressure 20-22 psi/138 Kpa)

D-HB with built-in 70°F/39°C rise electric booster (Minimum 110°F/43°C) (Min./Max.
flow pressure 20-22 psi/138 Kpa)

D-H1 without built-in booster (Minimum 180°F/70°C) (Min./Max.
flow pressure 20-22 psi/138 Kpa)

D-LF (Minimum 120°F/49°C - 140°F/60°C Optimum) (Min./Max.
flow pressure 20-22 psi/138 Kpa)

3. A manual shut-off valve for steam and water (supplied by others) should be installed in supply line to
allow for servicing of the machine. The shut-off valve should be the same size or larger than the
supply line.

4. A 3/4" Pressure Regulating Valve (PRV), should be installed on the incoming water supply line if water
flow pressure exceeds 20-22 psi/138 Kpa.

A PRV is standard equipment on Model D-HB.

A PRV is not standard equipment on Models D-H1 and D-LF. The PRV
may be obtained locally or direct from Champion.

Drain Connections

Refer to Fig. 3 for the location of the machine drain.

1. Models D-HB, D-H1, and D-LF are GRAVITY DRAIN machines equipped with a 1-1/2"
hose connection point. • Drain height for ALL MODELS must not exceed 15" above floor
level.

WARNING:

Connection of the machine to a drain line higher than the machine drain height will
prevent the machine from draining properly.
