WATER SUPPLY
The Combi-Steamer should only be connected to a cold water supply which meets the quality requirements by the
EPA on drinking water. Soft water must be at least 5 or 6 grains.
The recommended water supply pressure is 44 psi, but 22 to 87 psi will work.
The water connection is done on a 3/4” NPT thread fitting, and a manual shut off valve must be installed between
the main cold water supply and the units supply line.
NOTE:
A check valve is built into the unit to prevent backflow.
DRAIN CONNECTION
The Combi-Steamer is to be installed to comply with the applicable Federal, State, or local plumbing codes.
The unit has an integrated vented drain system which acts as a reverse flow check valve, so it may be connected
directly with a P-trap to the drain system.
Installation – Electric Units
(continued)
A minimum water conductivity of 20 micro Siemens is required for proper operation. If below this figure
the steam generator will over-fill.
The drain must have a constant slope and a diameter of 2 inches over its entire length to ensure sufficient
discharge during Auto Flush from the steam generator, which is 3/4 quarts per second.
The drain must be steam temperature resistant pipe, which average drain temperature is 150°F (65°C).
No hose should be used.
Should the water pressure exceed 87 psi, a pressure regulator must be installed into the supply line or
damage to the unit could result.
