WATER REQUIREMENTS
Proper water quality can improve warewashing performance by reducing spotting, lowering chemical
supply costs, improving productivity and extending equipment life. Local water conditions vary from
one location to another. The recommended proper water treatment for effective and efficient use of
this equipment will also vary depending on the local water conditions. Ask your municipal water
supplier for details about local water specifics prior to installation.
Recommended water hardness is 4 to 6 grains of hardness per gallon. Chlorides must not exceed 50
parts per million. Water hardness above 6 grains per gallon should be treated by a water conditioner
(water softener or in-line treatment). Water hardness below 4 grains per gallon also requires a water
treatment to reduce potential corrosion. Water treatment has been shown to reduce costs associated
with machine cleaning, reduce the need for deliming the dishwasher, reduce detergent usage and
reduce corrosion of metallic surfaces in the booster water heater and dishwasher.
Sediment, silica, chlorides or other dissolved solids may lead to a recommendation for particulate
filtration or reverse osmosis treatment.
If an inspection of the dishwasher or booster heater reveals lime build-up after the equipment has been
in service, in-line water treatment should be considered, and, if recommended, should be installed and
used as directed. Contact your Hobart Service office for specific recommendations.
BOLTS
STUDS
A NOTCH MUST BE ADDED TO BACKSPLASHES
OVER 6" HIGH ON CORNER MACHINES TO
PREVENT INTERFERENCE WITH DOOR
MECHANISM. NOTCH MUST EXTEND 5" FROM
FACE OF THE MACHINE.
A splash shield is available (at extra cost) for corner installations to cover the left side opening to the
wall. Install the splash shield on the left side using the two
1
/4-20 studs on the left rear corner with a
lockwasher and nut for each (Fig. 8) and using the two
1
/4-20 bolts, lockwashers and nuts on the left front
corner (fasteners are provided in the kit).
For corner installations, tabling with backsplashes over 6" high require that a notch be provided to
prevent interference with the door mechanism (Fig. 9).
