Leave an air gap between the hose
and the building drain, and don’t
allow water traps in the hose.
WARNING
TO AVOID DAMAGE OR INJURY, FOLLOW THE ELECTRICAL SCHEMATIC EXACTLY WHEN CONNECTING THE
UNIT.
HY-6E (CE) HyPerSteam™ convection steamers operate at 400 Volts (Three Phase) or 230 Volts (One Phase).

4.1.5 Branch Circuit Protection
Each conductor must have overcurrent protection. Connections to the unit must be watertight.
We strongly recommend that the HY-6E Steamer have its own branch circuit protection
.
4.1.6 Equipotential Terminal: In accordance with national regulations, each unit is fitted with an equipotential
terminal.
4.2 Water Connection(s)
Water pressure in the line should be between 30
and 60 PSIG (210 and 420 kPa). If pressure is
above 60 PSIG (420 Kpa), a pressure regulator
will be needed. A 19 mm BSPT connector is
used to attach the water supply to the water inlet
valve. The minimum water feed line diameter is
3/4 inch (13mm). Use a washer in the hose
connection. Do not allow the connection to leak,
no matter how slow it may be.
STEAM GENERATOR VOLUME (7.5 LITERS)
MUST FILL WITHIN THREE MINUTES AND 30
SECONDS.
Water Quality Requirements: For proper steam
generator performance, Total Dissolved Solids
(TDS) should not exceed 30 parts per million
(ppm), and the water pH should be 7.0 or higher.
4.3 Drain Connection
The HY-6E (CE) must be leveled front to back. A
Install a WRAS approved double-check valve or an
equally effective backflow preventive device in the
incoming cold water line at the point of connnection(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.
1½ inch (38mm) ID hose may be attached to the
drain pipe (supplied) by means of a hose. There
must be an air gap between the end of the hose
and the building drain.
WARNING
DO NOT CONNECT THE HOSE DIRECTLY TO A
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 two inch free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. THE DRAIN MUST
WITHSTAND HOT WATER.
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.
