If water hardness tests higher than 3 GPG, install the Scaltrol Water Treatment system
(see the Plumbing Options page) into the water line before the machine’s incoming
water connection point. A water shut-off valve should be installed to allow access for
service.
If water hardness tests lower than 3 GPG, install the water supply line directly to
the machine’s incoming water connection point. A water shut-off valve should be
installed to allow access for service.
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 these
devices as options (see the Plumbing Options page). Take care not to confuse static
pressure with flow pressure: static pressure is line pressure in a “no flow” condition (all
valves and services are closed); flow pressure is the pressure in the fill line when the
valve is opened during the cycle.
The manufacturer also recommends the installation of a shock absorber in the
incoming water line and offers these devices as options (see the Plumbing Options
page). This prevents line hammer/hydraulic shock—induced by the solenoid valve as
it operates—from causing damage to the equipment.
These machines have gravity discharge drains. All piping to the machine must be 2"
NPT and must not be reduced. There must also 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 5 GPM.
After installing the incoming fill line and drain line, slowly 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.
