Receiving and Installation
The glasswasher 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. Electrical
1
A 50-amp, single-phase 230 volt, 60 Hz dedicated circuit should be used to supply electrical
energy to the CMA-181GW glasswasher (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-181GW 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. Plumbing
2
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:
The supply water to the CMA-181GW 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).
This machine is equipped with Dema Valve and Dema Flow Disc which requires an
unrestricted water supply line minimum of ½”.
The CMA-181GW 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 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).
Warning:
If the water hardness is greater than 6 grains per gallon, a water softener is required to
prevent damage to heating elements (scale build- up) and booster tank rinse flow restriction.
Rinse flow restriction will cause the booster tank to expand and contract causing metal flex, which
will eventually crack the tank.

All 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
