Installation
Water Connections
1. All models have a 6 ft. exible hot water ll hose with a 3/4" GHT connector.
2. A 1/2" or larger main incoming supply line should be installed to the dishwasher.
3. A 1/2" or larger shut-off valve should be installed in the water supply line as close to the
dishwasher as possible for service.
4. The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for
the 40°F/ 22°C rise booster.
5. For the 70°F/39°C rise booster the hot water supply must provide a minimum of 110°F/43°C
measured at the dishwasher.
6. A water hardness of 3 grains/U.S. gal [51.3 mg/L] or less is recommended.
NOTE:
Plumbing connections must comply with national or local plumbing and sanitary codes.
Make sure that the exible water supply and drain hoses are not kinked.
1. The dishwasher has a 6ft. 3/4" I.D. drain hose. The maximum drain height
connection must not exceed 3 ft.[9 m].
The recommended drain height is 17" [.4 m] or less above the oor.
2. The drain hose is secured to the rear of the machine by a clamp to maintain a
goose-neck bend in the drain hose.
3. A 3/4" hose barb tting is strapped to the drain hose to use in connecting the
drain hose to building drain line.
The service part number for the
hose barb is P/N 0512321.
4. Install the drain hose to a "WYE" drain tting. Connection to a "TEE" tting will
prevent the dishwasher from draining completely.
5. The maximum drain ow is 8 U.S. gpm/7 Imp. gpm/30 L.P.M.
6. Make sure the drain hose does not kink. Kinks will prevent the dishwasher
from draining completely, and the dishwasher will overow out the front door.
Drain Connections
! ATTENTION !
Do not connect the drain hose to a disposer. The dishwasher will not drain correctly.
