| STERO UNDERCOUNTER DISHWASHER & GLASSWASHER
UNPACKING
Immediately after unpacking the dishwasher, check for possible shipping damage. If this machine is found to
be damaged, save packaging material and contact the carrier within 15 days of delivery.
LOCATION
Prior to installation, verify that the electrical supply agrees with the specifications on the machine data plate,
which is located on the top of the door.
Steam generated from normal operation may escape from the door. Wood, laminates, veneers, etc. are
unsuitable materials for use in areas exposed to dishwasher steam and detergents. Stainless steel or other
moisture-resistant shields are recommended for surfaces adjacent to dishmachine sides and top.
LEVELING
The machine must be level to operate properly. Place the dishwasher in its operating location. Level the machine
before any connections are made. Using a carpenter's level placed diagonally on the rack tracks, level the
machine front to back and side to side by threading the adjustable feet in or out. After leveling the machine,
cover the exposed threads of the adjustable feet with black rubber tubing supplied. (See separate instructions
furnished with machine.)
WATER REQUIREMENTS
Proper water quality can improve ware washing performance by reducing spotting, enhancing effectiveness of
labor and extending equipment life. 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 your local water conditions prior to
installation.
Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness may cause excessive
formation of lime scale. Water hardness above 3 grains per gallon requires water treatment. Water treatment
has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher, and
reduce detergent usage in the dishwasher.
High iron levels in the water supply can cause staining and may require an iron filter. High chloride
levels in the water supply can cause pitting and may require a chloride removal system. Contact your local
water treatment professional for proper water treatment.
Sediment may require a particulate filter. Dissolved solids may require water treatment such as a water soft-
ener, reverse osmosis system, etc. Contact your local water treatment professional for proper water treatment.
If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment has been in
service, water treatment is recommended. If a water softener is already in place, ensure there is a sufficient
level of salt.
A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied by others)
in the common water supply line at the service connection.
