Level the steamer left-to-right, and pitch it slightly to the front (maximum 1/4 inch) by adjusting the optional legs or the bullet feet on the optional stand.

There must be a free air gap between the end of the drain hose and the building drain. The free air gap should be as close as possible to the unit drain. There must also be no other elbows or other restrictions between the unit drain and the free air gap.

Install the drain line with a constant downward pitch (see Diagram 9-1 and 9-2 at left). IMPORTANT: Do not allow water traps in the line. A trap can cause pressure

build-up in the cooking compartment, which may cause the door gasket to leak.

For a proper drain line connection, the drain line must have a constant downward pitch of at least 1/4” per foot. Observe local code regarding air gap spacing and drain connections.

COUNTER-MOUNTED UNITS

This section is applicable when the steamer will be ﬂush-mounted to a counter. All four edges of the bottom of the steamer must be sealed with RTV silicone sealant to the counter if optional 4 inch legs are not used. Counter must be made of a noncombustible material such as metal or tile.

Diagram 9-2

DO NOT PLACE A LOLO STEAMER ON A CONVENTIONAL UNDERCOUNTER REFRIGERATOR. THEY ARE NOT DESIGNED TO SUPPORT THE WEIGHT OR INSULATED AGAINST THE HEAT PRODUCED BY THE STEAMER. FAILURE TO USE A PURPOSEBUILT REFRIGERATED EQUIPMENT STAND COULD RESULT IN REFRIGERATOR FAILURE, UNSAFE OR SPOILED FOOD AND EVEN MELTED PLASTIC COMPONENTS IN THE REFRIGERATOR.

STAND STACKED UNITS

This section is only applicable if you are installing two steamers on the optional support stand. The steamers are positioned on the top and bottom shelf that are standard with LoLo Steamer Stands.

1. Water Connections Separate water supply connections must be provided for each unit. At each wa-

ter inlet valve a ¾” NH connection (garden hose type) is used to supply water at the pressure and delivery rate speciﬁed on page 5 and 8.

2. Electrical Supply Connections Separate electrical connections are required for each steamer on the stand.

NOTE: Each steamer must have its own branch circuit protection.

3. Drain Connections Both steamers must be leveled left-to-right; and pitched to the front (maximum

of ¼”) by adjusting the bullet feet or casters on the steamer stand. Make sure both steamer drain connections are free-venting and slope continuously to the ﬂoor drain.

REFRIGERATED STAND MOUNTED STEAMERS

IMPORTANT: Do not mount a LoLo Steamer on a conventional undercounter refrigera-

tor. Steamers must be placed on a refrigerated equipment stand, such as the LoLo LRES Series, which are speciﬁcally designed to support the weight of heavy cooking equipment; and heavily insulated to resist the heat generated by a working steamer.

energy savings; or

• STANDBY – for Ready Mode, with even more energy savings.

4. POWER - ON/OFF Switch

5. Water Reservoir DRAIN VALVE Handle –

• OPEN when at 9:00 o’clock position – Allows water to drain from reser-

voir.

• CLOSED when at 6:00 o’clock position – Allows water to ﬁll reservoir

when Power switch is ON and Timer is set or in (manual) ON position.

The Timer can be used in three ways:

1. In the OFF position, the steamer stays ready for start-up.

2. When a cook time is set, the unit steams until the timer runs down to DONE. At that time, steaming stops and a beeper sounds until the user turns the knob to another position.

3. With the timer turned to the ON position, the unit steams continuously.

OPERATING PROCEDURES

1. Make sure Water Reservoir Drain Handle is in “CLOSE” position.

2. Press the ON/OFF switch located on the control panel to ON. The steam generating reservoir will ﬁll.

3. Rotate timer knob to the ON position.

4. Choose STEAM LEVEL: HIGH PERFORMANCE or ENERGY SAVER. In approximately 10-15 minutes the READY light will come on.

5. Load food into pans in uniform layers. Pans should be ﬁlled to about the same levels and should be level on top. This will ensure pan-to-pan cooking consistency.

6. Open the door and slide the pans onto the supports. TIP: If you will only be steaming one pan, put it in the middle position.
