OM/SM-HY-6E(CE)

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).

ELECTRICAL SUPPLY CONNECTIONS

Model Voltage Maximum Kw Field Wiring Current Demands

HY-6E (CE)

400 - 3 Phase 19 10 AWG 26.5 Amps

230 - 1 Phase 19 4 AWG 72 Amps

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)

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 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 ½ 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

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.
