Unified Brands HY-6E(CE) Electrical Supply Connections, Model, Voltage, Maximum Kw, Field Wiring

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

4.1.5Branch 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.

4.1.6Equipotential Terminal: In accordance with national regulations, each unit is fitted with an equipotential

terminal.

4.2Water 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.

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.

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.

4.3Drain 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.

Leave an air gap between the hose and the building drain, and don’t allow water traps in the hose.
