6. Branch Circuit Protection
Each LoLo steamer, including individual stand-stacked units, should have its
own branch circuit protection and ground wire.
WATER CONNECTION
Install a check valve to prevent back flow into the incoming cold water line, as
required by local plumbing codes. Water pressure in the line should be between 30
and 60 PSI. If pressure is above 60 PSI, a pressure regulator should be installed. These
pressures must provide a delivery rate of 2 gallons per minute for proper steamer
operation.
A 3/4 inch female NH connector (garden hose type) is used to attach the water supply
to the inlet valve. The minimum inside diameter of the water feed line is 1/2 inch. Use
a rubber washer in the hose connection. Do not allow the connection to leak, no matter
how slowly. IMPORTANT: Do not over-tighten hose connections.

DRAIN CONNECTION
Model Drain ID Hose Size Required
ST-4E 1.5”
ST-6E 1.5”
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 non-
combustible material such as metal or tile.
STAND STACKED UNITS
This section is only applicable if you are installing two steamers on the optional sup-
port 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.
Installation Instructions
DO NOT CONNECT THE DRAIN DIRECTLY
TO A BUILDING DRAIN. BLOCKING THE DRAIN
IS HAZARDOUS.
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.

bottom they include:
1. Steamer READY indicator light – Indicates the steam generator reservoir is at
temperature and the cavity is hot enough to begin steaming.
2. 60 minute Timer Control with continuous ON position – See Timer Functions
below.
3. STEAM LEVEL 3-way Toggle Switch – Providing the following options:
• HI PERFORMANCE – For maximum power and fastest cook times (a la
carte cooking);
• ENERGY SAVER – For batch production, with slower cook times but
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 gener-
ating reservoir will fill.
3. Rotate timer knob to the ON position.
4. Choose STEAM LEVEL: HIGH PERFORMANCE or ENERGY SAVER. In approximate-
ly 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 consis-
tency.
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.
