PLUMBING CONNECTIONS

WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY

AND PLUMBING CODES.

WATER REQUIREMENTS

Water Requirements

Proper water quality can improve the taste of the food prepared in the steamer, reduce liming in the steam generator and extend equipment life. Local water conditions vary from one location to another. Ask your municipal water supplier for details about your local water supply prior to installation.

Supply Pressure 20 — 60 psig Hardness* less than 3 grains Silica less than 13 ppm Total Chlorine less than 4.0 ppm pH range 7 — 8 Undissolved Solids less than 5 microns

* 17.1 ppm = 1 grain of hardness

Presence of sediment, silica, excess chlorides or other dissolved solids may lead to a recommendation for alternate form(s) of water treatment. Test the water with the test strip included with the combi oven. Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases. A local water treatment specialist should be consulted before installation of steam generating equipment.

Water Supply Connections (Fig. 2) A water filter system is recommended for the water supply line going to the treated water inlet of your

oven. Follow the recommendations for use and installation instructions shipped with the water filter. If a water filter is not installed, the oven warranty may be limited.

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" hose bibb (3/4" 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

ELECTRIC SUPPLY CORD

Fig. 2

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.

Open the door. Place the product to be cooked in suitable containers and slide into the racks or place the containers securely on shelves in the oven.

When loading a 10 level oven with the landing table (Fig. 6), the bottom frame of the rack should be secured by the rotary lock. Move the loaded landing table to the front of the open oven; secure the landing table to the oven by actuating the locking clamp (or use your body to hold the landing table against the oven). Rotate the lock-knob to release the pan rack and carefully roll the loaded pan rack into the oven while making sure that the landing table does not separate from the oven during the transfer.

NOTE: When the landing table is not in use on the 10 level oven, make sure the rack retainer (delivered with the oven) is fitted under the fan baffle to prevent the pan rack from tilting when pans are being removed.

When loading a 20 level oven with the trolley (Fig. 7), make sure the handle is locked in the down position so the rack is held securely to the trolley with its lifting hooks. Carefully move the loaded trolley completely into the open oven. When the rear frame of the rack is positioned behind the edge of the retainer, raise the handle to lower the rack-frame to the oven door.

UNLOADING THE OVEN

Allow the door to be slightly-opened for a few seconds to allow hot air and steam to escape. Stand behind the door while opening.

When unloading a 10 level oven, move the landing table so the clamp locks the landing table to the front of the oven (or use your body to hold the landing table against the oven). Remove the landing table handles and clamp them to the bottom of the hot oven pan rack. Carefully roll the hot pan rack onto the landing table platform while making sure that the landing table does not separate from the oven during transfer. Rotate the knob to allow the rack to move completely to the front of the landing table; and rotate the knob back to lock the pan rack in place.

When unloading a 20 level oven, move the trolley (Fig. 7) into the oven until the "lift-hooks" are inserted into both sides of the front frame of the rack in the correct "lift" position. Lower the trolley handle until it stops; the loaded rack is lifted from its retainer and held securely to the trolley by the "lift-hooks". The trolley may now be removed from the oven with the loaded rack securely held in place.
