provides the serviceman with the opportunity to fine tune the machine to deliver the proper
amount of water with each cycle.
Note: The required flowing water pressure to the dishwasher is 15-65 PSIG. If pressures higher
than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the
dishwasher (by others). If flowing pressure is lower than 15 psi, improper machine operation may
result.
The EST-VL Dishmachine has a 2” drain. The following section explains how to connect the
drain.
Notice to Plumber: The plumber connecting this machine is responsible for making certain that
the water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher
Ask your municipal water supplier for details about your local water conditions prior to installation.
Recommended water hardness is 3 grains per gallon or less.
Note: high iron levels in the water supply can cause staining and may require an iron filter. High
chlorine levels in the water supply can cause pitting and may require a chloride removal system.
If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment has
been in service, water treatment is recommended. If water softener is already in place, ensure
there is a sufficient level of salt.
2.2.3. Connecting the Scrap Accumulator and Drain
The scrap accumulator is designed to perform two basic functions:
1. It allows a method to discharge all the heavy solids out of the machine with each
wash cycle.
2. It provides accumulation capacity to allow draining the contents of one cycle
regardless of the discharge rate of the existing drain.
The drainpipe is connected to the scrap accumulator drain using a 2” no-hub connector as shown
in
Figure 2.2.3 below.
