OM-HY/6G(CE) 9
5. Burner Air Adjustment
The unit is equipped with fixed aeration type burners which have no provision for
air inlet adjustment.
6. Equipotential Terminal
In accordance with national regulations, each unit is fitted with an equipotential
terminal.
7. Water Supply Connection (Treated Water)
The HY-6G CE model is fitted for a 3/4 inch B.S.P.T. cold water connection. The
water supply must be provided at a rate of not less than 2.7 liters (0.70 gallons)
per minute. Pressure must be 2.0 to 4.0 Bar (30 to 60 PSI) maximum.
Water quality minimums require totally dissolved solids (T.D.S.) of 30 parts per
million maximum, and a water pH of 7.0 or greater. If the available water supply
fails to meet these requirements, water treatment equipment must be provided
to ensure steamer reliability and operating life.
Install a WRAS approved double-check valve or an equally effective back-flow
preventive device in the incoming cold water line at the point of connection(s)
to the steamer and in compliance with all local plumbing codes. This installation
must be per WRAS-IRN R160 Schedule 2-15(1). For units with the dual water
connection option, a double-check valve shall be installed on each water line.
Do not allow the connection to have any leak, regardless of how small.
8. Untreated Water Second Connection
As discussed previously, the flow of water used for steam suppression in
the drain is much greater than the amount of water used to generate steam.
The second connection on steamers (see illustration under “Water Quality &
Treatment” section) permits the installer to supply treated water to the steam
generator and untreated water to the drain. With “split water” feature, the initial
fill requirement for treated water is 3.5 U.S. gallons (19 L) within 2.5 minutes.
The requirement for treated makeup water is 0.12 gallon (0.45 L) per minute per
cavity. A field retrofit kit is available for single water connection if required.
9. Drain Connection
The HY-6G (CE)Steamer must be leveled front to back. A 38mm (1½ inch) ID
hose may be attached to the drain pipe (supplied) by means of a hose. DO NOT
CONNECT THE HOSE DIRECTLY TO A BUILDING DRAIN. 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.
IMPORTANT: Do not allow any water traps in the line. A trap can cause pressure to
build up inside the cavity during steaming, which will make the door gasket leak.
CAUTION
DO NOT USE PLASTIC PIPE. THE DRAIN MUST
WITHSTAND HOT WATER.
Installation
Gas input is through a ½ inch B.S.P.T
connection at the left rear of the unit.
