If water hardness tests at 3 GPG or lower, connect the machine water line (installed
at the factory, 3/4" Male GHT connected to a true 1/2” ID line) to the facility water line.
A water shut-off valve should be installed in the water line between the facility supply
and the machine to allow access for service. The water supply line must be capable
of a minimum of 10 PSI “flow” pressure at the recommended temperature indicated
on the data plate.
The manufacturer recommends the installation of a pressure regulating valve (PRV)
in the incoming water line to ensure proper flowrate at all times and offers them as an
option (see the Plumbing Options page). The PRV comes standard on the UH30-E-
SEER.
Do not confuse static pressure with flow pressure. Static pressure is the line
pressure in a “no flow” condition (all valves and services are closed). Flow pressure is
the pressure in the fill line when the fill valve is opened during the cycle.
The manufacturer also recommends the installation of a shock absorber on the incoming
water line and offers them as an option (see the Plumbing Options page). A shock
absober comes standard on the UH30-E-SEER. This prevents water hammer or
hydraulic shock—induced by the solenoid valve as it operates—from causing damage
to the equipment.
The machine has a pumped (pressure) drain capable of pumping waste water to
a height of 24” above the floor to the kitchen’s drain system. Each dishmachine is
supplied with a drain hose. When installed, it will extend from the rear side of the
machine. There must be an air-gap between the machine drain line and the floor sink
or drain at least 1.5 times larger than the drain hose. If a grease trap is required by
code, it should have a flow capacity of 12 GPM.
After installing the incoming fill line and drain line, turn on the water supply to
the
machine. Check for any leaks and repair as required. All leaks must be repaired
before operating the machine.
