If water hardness is higher than 3 GPG and a water softener is not being used,
install the optional SPS into the water line between the facility water line and the
machine water line (installed at the factory). See the Plumbing Options page for more
information on the SPS. Observe proper inlet/outlet water directions. A water shut-o󰀨
valve should be installed before installing the SPS to allow access for service.
If water hardness is lower than 3 GPG, install the water supply line (1/2” ID pipe
size minimum) to the machine’s incoming water connection point using copper pipe
(or order the 1/2” ID exible hose kit o󰀨ered by manufacturer). A water shut-o󰀨 valve
should be installed before installing the SPS to allow access for service.
The manufacturer has an optional water pressure regulator (see Plumbing Options
page) to accommodate areas where water pressure uctuates or is higher than the
recommended pressure. Take care not to confuse static pressure with ow pressure:
static pressure is line pressure in a “no ow” condition (all valves and services are
closed); ow pressure is the pressure in the ll line when the valve is opened during
the cycle.
It is suggested that the optional shock absorber (see Plumbing Options page) be
installed on the incoming water line. This prevents water hammer (hydraulic shock)
from causing damage to the equipment.
The machine drain requires a minimum 2” NPT piping that is pitched at least 1/4” per
foot. There must also be an air-gap between the machine drain line and the floor sink
or drain. If a grease trap is required by code, it should have a flow capacity of
5 GPM.
After installing the incoming ll 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.
