Ventilation - Vent Fan Control for Standard Model Only

Standard model installations using an approved vent hood may require a vent
fan signal. This signal is supplied by the dishwasher control circuit. A qualified
installer must connect a signal circuit to the fuse holder and a common
neutral terminal provided. See Fig. 15.

Installation

CAUTION: To prevent damage to the dishwasher do not connect vent fan motor

to the Line Power 120VAC 1.0 Amp fused connection terminals. Damage to any
component caused by improper installation is not covered by the limited warranty.

The fused 120VAC Line Power is designed to operate an external vent fan contactor
only (supplied by others), and is limited to 1.0 AMP maximum load. The 120VAC
signal is available when the dishwasher power switch is turned ON.

Cleaning - Deliming

Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white haze
and, in cases of heavy accumulation, may appear as a granular solid. The generic name for
mineral deposits is lime. The removal of lime deposits is called deliming. The dishwasher should be
delimed regularly.

WARNING:
Death or serious injury may result when deliming solution is mixed with
sodium hypochlorite (chlorine bleach) sanitizing agent. Mixing may cause
hazardous gases to form. Deliming solution and other acids must never be
mixed with chlorine, iodine, bromine, or fluorine.

WARNING:

Deliming solutions can cause severe irritation and possible chemical burns.
Always wear protective clothing and goggles when handling chemicals.

NOTE: Contact a qualified chemical supplier for deliming chemicals and
instructions to delime the dishwasher. Follow all of the chemical supplier's
directions making sure to always wear eye protection, rubber gloves and
rubber aprons when handling chemicals and deliming the machine.
