The Dishwasher Formula

Five Elements for Cleaning Dishes

A Perfect Score means Clean Ware for your customers . . .

Peak Dishwasher Performance for you.

Point Value

1. Time ..................................................................................

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

2. Temperature ......................................................................

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..........................................................................

Pre-scraping and rinsing removes large food particles from the dishes.

Proper washroom ventilation and humidity shortens dish drying time.

GENERAL

INSTALLATION

Unpacking

CAUTION:

Care should be taken when lifting the machine to prevent damage.

1. Immediately after unpacking the machine, inspect for any shipping damage.

If damage is found, save the packing material and contact the carrier immediately.

2. Remove the dishwasher from the skid. Adjust the feet if required, then move the

machine to its permanent location.

3. Level the machine (if required) by placing a level on the top of machine and adjusting

the feet. Level the machine front-to-back and side-to-side.

4. Remove the two dishracks from the interior of the machine.

NOTE:

The installation of your machine must meet local health codes.

Changing from Straight-through to Corner Operation

Your door-type dishwasher is shipped from the factory in a straight-through configuration. The following instructions explain how to convert your machine for corner operation.

Refer to Fig. 1 below.

1. Place the dishwasher so the operator controls are readily accessible.

2. Minimum clearance from any corner wall is 5-1/4" (133mm).

INSTALLATION

Changing from Straight-through to Corner Operation (cont’d)

Refer to Fig. 2 and perform the steps below.

1. Remove the front rack guide (A). Discard the square spacers.

2. Move front rack guide (A) to the left side of the rack tracks. (See Fig. 2b) Use existing hardware.

3. Unbolt the track (B) and rack support rod (C).

4. Remove and save the two remaining fasteners from rear track.

5. Bolt (B) and (C) as shown in Fig. 2b.

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 L1 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.

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.

INSTALLATION

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.

Ventilation

NOTE:

Ventilation must comply with local sanitary and plumbing codes.

CAUTION:

Exhaust air should not be vented into a wall, ceiling, or concealed space of a building. Condensation can cause damage.
