PLUMBING CONNECTIONS

WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY

AND PLUMBING CODES.

WATER SUPPLY CONNECTIONS (Fig. 2)

The water filter, provided, must be installed in the water supply line going to the treated water inlet or

your oven warranty may be voided. Follow the instructions included with the water filter that is provided

with the oven. Refer to the Water Filter manual shipped with the Water Filter.

Connect treated potable water ( must be cold) to the inlet labeled for treated water to supply the steam

generator tank. Untreated water contains scale producing minerals which, if supplied to the steam

generator, can precipitate onto the surfaces in the steam generator tank. Due to the temperatures in

the tank, the minerals can bake onto the surfaces and components. This can result in early component

failure and reduced product life. Sensors in the steam generator tank use ions in the water to detect

the water level. Do not use distilled (fully demineralized or de-ionized) water as this could provide a

false reading to the sensors. Strainers and filters will NOT remove minerals from the water.

Connect untreated potable water (must be cold) to the inlet labeled for

untreated water to supply the condenser which cools the drain water.

Both external-threaded nylon inlets (

/4" NSHT - National Straight Hose

Thread) are located at the rear of the oven. The nylon threads should be

treated carefully so the connections do not leak. A manual shutoff valve

should be provided, convenient to the oven, for each water supply line; both

of these valves should be open when the oven is in operation. Water

pressure for both incoming water lines should be between 20 and 60 psig.

Refer also to CLEAN CYCLE DELIMING PROCEDURE, page 38.

DRAIN CONNECTION

CAUTION: In order to avoid any back pressure in the oven, do not connect solidly to any drain

connection.

The drain connection, 1

/2" NPT threaded fitting, is located underneath the oven at the rear. The drain

line must be plumbed to an open gap-type drain. Drain piping must have suitable pitch, have

appropriate support along its length and have no connection to other piping. The material used in the

drain line should be heat resistant to at least 212°F. The open drain should be located between 3 and

5 feet away from the perimeter of the oven to reduce potential damage from moisture-corrosion. The

drain line from the oven must not be combined with any drain line from another device.

ELECTRICAL CONNECTION — Cord Connected Ovens

WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE

APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL

ELECTRICAL CODES.

WARNING: THE SUPPLY CORD ON THIS OVEN IS PROVIDED WITH A GROUNDING PLUG. THE

OUTLET TO WHICH THIS PLUG IS CONNECTED MUST BE PROPERLY GROUNDED. IF THE

RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN.

The wiring diagram is located on the inside surface of the right side panel as you face the oven.
