2.2.Receiving and Installation

The dishwasher is shipped from the factory in a corrugated box on a wooden pallet. The installation guidelines give a systematic procedure for setting up the machine.

Start by removing the packaging material. Unwrap the machine and check for the following component parts:

The Wash Tank Scrap Screen is shipped inside the wash cavity of the machine. This screen must be in place during operation. It has been designed to perform two basic functions:

1.Strain water that is circulating through the spray arms and pump assembly.

2.A basket to catch broken glass, or heavy solids that may plug the impeller.

Set the machine in place, and level from side-to-side and front-to-back.

2.2.1. Electrical1

A 50-amp, single-phase 230 volt, 60 Hz dedicated circuit should be used to supply electrical energy to the CMA-180UC dishwasher (see specification sheet page 2). This system requires three power wires, which include a current carrying neutral. An additional fourth wire must be provided for ground. CMA and local codes require the CMA-180UC to be hardwired using #8 AWG (90°C) copper wire (minimum). Approximately 4-feet of ¾” flexible conduit with power leads (L-1, L-2, Neutral and Ground) extending out of the conduit are provided for easily connecting the power at installation. The power connection must be located such that there is sufficient length of the flexible conduit remaining to permit the machine to be moved for cleaning.

2.2.2. Plumbing2

The machine is equipped with a ½” NPT connection located at the lower left-hand corner (facing the back) of the machine. A 140°F water line should be plumbed to this point (see specification sheet page 2). The water line used must be of sufficient length and flexibility to permit the machine to be moved for cleaning.

Important: New machines equipped with Dema Valve and Dema Flow Disc requires an unrestricted water supply line minimum of ½”.

The supply water to the CMA-180UC must be a minimum of 140°F at 24 PSI (Pounds per Square Inch) with a 6 GPM (Gallons Per Minute) flow rate and 60 GPH (Gallons Per Hour) recovery rate. The pipe supplying the water must be ½” minimum. The plumbing connection is located at the back of the machine. (See specification sheet on page 2).

The CMA-180UC may be supplied with an optional drain pump for elevated drains. For floor gravity drain applications the drain pump should not be used and a good commercial grade hose needs to be connected to the discharge side of the diverter valve (drain valve) and run to the floor drain. If removing a drain pump, safe-end (insulate electrically) the white and purple wires and secure them out of the way. If a drain pump is used with a floor drain, the drain hose must rise 12 to 16” before dropping to the floor drain (to reduce any chance of the pump cavitations).

1,2All electrical and plumbing connections must be made by a qualified person who will comply with all available Federal, State, and Local Health, Electrical, Plumbing and Safety codes
