Electric Booster Water Heater Series

Literature      Dimensions & Specifications  Installation & Service Manual

INNER TANK CONSTRUCTION

Standard horizontal booster inner tanks are constructed of stainless steel. Will not rust - 10 year warranty.

ELEMENTS

Heating elements are 1" I.P.S., utilizing copper sheathing on the hairpin rods to provide the ultimate in corrosion resistance, long life and efficient operation. All models specifying 480V to 600V are equipped with four bolt flange mounted heating elements utilizing copper sheathing on the hairpin rods and stainless steel flange to provide the ultimate in corrosion resistance and long life.

JACKET AND INSULATION

An attractive rectangular jacket with backed enamel finish, stainless steel front panel. Two inches of fiber glass insulation surrounds the inner tank. Sturdy legs are standard or stainless steel hanging supports for under counter suspension are available. (Specify when ordering.)

CONTROLS

A custom designed rapid response thermostat with adjusting dial, switches a magnetic contactor which completes the power circuit to the heating elements except on 4B and 5B models which are controlled by a thermostat. This electrical system is prewired on the right hand side of each booster away from high ambient temperatures. A neon pilot light, mounted on the front, is wired to indicate that there is power to the heater and to show when the booster is operating. Prewired electrical control panel mounted on the booster complete with magnetic contactors, internal adjusting thermostat and pilot light.

PLUMBING INSTALLATION

1. Locate booster as close to dishwasher as possible. Must be connected with copper tubing.
2. Insure that incoming water is 140°F to pressure reducing valve furnished preset for 20 PSI.
3. It is mandatory that a diatrol expansion chamber and shock absorber be installed in the line between booster and dishwasher. (as close to dishwasher as possible)
4. Install relief valve (furnished) on heater and plumb discharge in accordance with local codes.
5. Install pressure temperature gauge in a tee on inlet between reducing valve and booster.
6. Unions should be used in connecting the piping to the booster.
7. It is recommended that the inlet and outlet lines be insulated to prevent heat loss.
8. Check flow pressure with water flowing through the booster and, if necessary, readjust the pressure reducing valve to 20 PSI or to pressure recommended by dishwasher manufacturer.

	Hanging brackets are supplied if specified with the order

ELECTRICAL INSTALLATION

1. Ensure booster is full of water before turning on electricity. Elements will burn out immediately without water.
2. Check booster data plate for correct amperage voltage and phase, and size supply wiring accordingly.
3. Supply wires must be suitable to 75°C.
4. A fused disconnect switch of at least 125% of the booster amperage rating must be installed between the power supply and the booster.
5. Insure that plumber has installed booster with access to the elements and control panel.
6. Set thermostat to give desired water temperature at dishwasher (usually 180°F).
7. Lift relief valve handle to be sure booster is completely filled with water.
8. The pilot light indicates when power is on, and the booster is operating.
