ADS Warranty.
WARNING:
DO NOT OPERATE MACHINE WITH SPRAY ARM INSTALLED
UNTIL MACHINE IS FLUSHED WITH WATER.
Fill machine with water and run though one cycle without spray
arm in place. This will flush installation debris from tank and
pump and prevent damage to spray arm bearing.
Water Heaters or boilers must provide the minimum temperature
required by the type of machine and a minimum recovery rate of
68 gallons per hour. The recommended temperature range for
optimal performance is 130-140 degrees F. Caution: Do not
exceed water tempertures above 150 degrees F.
Dishmachines are 120 volt and require a 20 amp clean
circuit and suitable ground. It is recommended that new
equipment be installed with new circuit breakers.
IMPORTANT:
NOTE TO INSTALLER:
IMPORTANT- Dishwasher MUST be installed to
allow for service of motor and rear plumbing. For the
pumped drain model, the water inlet line must be
flexible and long enough to remove the machine, as
well as the power line and drain hose. This is a code
requirement for cleaning and servicing undercounter
dishwashers.
