3. Water Connection(s)
Install a check valve to prevent back flow in 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 will be needed.
These pressures must provide the 1.5 gallons per minute required for proper
steamer function.
A 3/4 inch female NH connector (garden hose type) is used to attach the water
supply to the inlet valve. Minimum inside diameter of the water feed line is 1/2
inch. Use a washer in the hose connection. Do not allow the connection to leak,
no matter how slowly. Do not over-tighten hose connections.
This equipment is to be installed to comply with the basic plumbing code of the
Building Officials and Code Administrators International, Inc. (BOCA) and the Food
Service Sanitation Manual of the Food and Drug Administration (FDA).
4. Drain Connection
Level the steamer front to back, 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 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.
Proper Drain Line Connection: 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.
5. Factory-Stacked Units
This section is applicable only if you are installing factory-stacked units.
Installing stacked steamers is similar to installing a single unit. The steamers are
stacked and assembled at the factory and delivered with the water connections
and drain hoses required for a single point connection.
A. Water Connection
The same water supply connection is used for both units. At the water inlet
valve a 3/4 inch female NH connector (garden hose type) is used for the
water supply.
B. Electrical Supply Connection
Separate electrical connections will be required for each steamer to be
stacked. Each steamer unit must have it’s own branch circuit protection.
C. Drain Connection
Steamers must be leveled front to back, and pitched to the rear (maximum
1/4 inch) by adjusting the bullet feet on the cabinet or stand base. For all
factory-stacked steamers, a 2-1/2 inch ID hose is attached to the unit
drain. It must be rated for boiling water.
6. Counter-Mounted Units
This section is applicable if the steamer will be mounted to a counter. All four
edges of the bottom of the steamer must be sealed with RTV to the counter if the
4 inch legs are not used. Counter must be made of a noncombustible material
such as metal or tile.

WARNING
DO NOT CONNECT THE DRAIN DIRECTLY
TO A BUILDING DRAIN. BLOCKING THE
DRAIN IS HAZARDOUS.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.
IMPORTANT
DO NOT ALLOW WATER TRAPS IN THE LINE.
A TRAP CAN CAUSE PRESSURE BUILD-UP IN
THE CAVITY, WHICH MAY CAUSE THE DOOR
GASKET TO LEAK.
WARNING
DO NOT STACK STEAMERS WHEN
LEGS ARE USED.
