If water hardness tests at 3 GPG or lower, connect the machine water line (installed
at the factory) 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 Delta HT-E-SEER has a pressure regulating valve (PRV) installed at the
factory to accommodate areas where water pressure fluctuates or is higher than the
recommended pressure. This machine operates at 10 PSI flow pressure. 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.
A shock absober comes standard on the Delta HT-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 machine's drain pump and is supplied with a drain hose. There
must be an air-gap between/around the machine drain hose and the floor drain or
sink. The floor drain or sink must be at least 1.5 times larger than the machine 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 hose, 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.
