INSTALLATION
Unpack the dishwasher
CAUTION:
Care should be taken when lifting the machine to prevent damage.
NOTE:
The installation of your machine must meet all applicable health and safety codes.
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. Move the machine to its
permanent location.
3. Machine must be placed on a sound self-draining floor.
4. Level the machine (if required) by placing a level on the top of the
machine and adjusting the feet. Level the machine from
front-back and side to side.
5. Refer to Fig 1. Remove (2) screws that hold the front panel.
Remove the front panel in preparation for service connections.
Electrical Connections
WARNING:
Electrical grounding connections must comply with all applicable 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 electri-
cal specifications before connecting to the incoming service through a fused disconnect
switch.
2. Recommended electrical supply is three phase, permanently wired via wall switch
mounted adjacent to machine. Machine may also be installed on 25A single phase (15A
single phase with reduced rinse heating). Easy on site conversion of standard machine for
any of these requirements.
3. A knock out is provided at the lower right rear corner (as viewed from the front) for
electrical service connection. A fused disconnect switch or circuit breaker (supplied by
others) is required to protect the power supply circuit.
4. Remove (2) lower screws from the front panel of the machine to expose the electrical
controls.
5. Three phase or single phase incoming wire connections are made at the bottom of the
machine’s main terminal block. The main terminal block is located on the side of the front
right post of the dishwasher.
