Recommended water hardness is 4-6 grains of hardness per gallon. Chlorides must NOT exceed 50 parts per million. Water hardness above 6 grains per gallon should be treated with a proper water conditioner (water softener or in-line treatment). Water hardness below 4 grains per gallon also requires water treatment to reduce its corrosive effects. Sediment, silica, chlorides or other dissolved solids may require particulate filtration or reverse osmosis treatment. Proper water treatment has been shown to reduce machine cleaning, mineral build-up, detergent usage and corrosion of metal surfaces in booster heaters and dishwashers.

Damage caused by water conditions is not covered under warranty.

WATER PIPING

WARNING: All piping and plumbing connections must comply with applicable sanitary, safety and plumbing codes.

CAUTION: All piping and any components connected to this appliance for the purpose of space heating shall be suitable for use with potable water. Toxic chemicals, such as used for boiler treatment, shall not be introduced into the potable water used for space heating. This appliance, when used to supply potable water, shall not be connected to any heating system or component(s) previously used with a non-potable water heating appliance or system.

The inlet and outlet water connections are 1 inch NPT (inlet is 1” female pipe, outlet is 1” male pipe). An inlet and outlet union adaptor is provided with your POWERMAXtm Booster Heater.

The inlet water supplied to the booster heater should be a minimum of 110-degrees Fahrenheit, except in the case of single rack, door type dishwashers and some “water- saver” conveyor machines, in which case incoming water can be as low as 45 degrees Fahrenheit. DO NOT connect the POWERMAXtm Booster Heater to a cold water supply pipe if it is to be used with a full flow conveyor dishwasher.

Recommended flowing water pressure to the booster heater is 45 p.s.i. Flowing water pressure at the dishwasher rinse valve should be 20 p.s.i. An optional pressure regulating valve and pressure gauge for the booster heater outlet is available from Vanguard Technology if the dishwasher is not equipped with these items. The supply water inlet to the booster heater does not require a pressure-regulating valve unless the supply water pressure exceeds 50 p.s.i. A full-flow shut off valve must be provided in the water supply piping to the booster heater. Installation of a suitable water hammer arrester is recommended between the booster heater and the dishwasher rinse valve.

A drain valve assembly is provided for installation on the lower outlet at the back of the booster heater.

The Temperature and Pressure Relief valve is installed at the left side of the booster heater. Install a suitable 3/4” i.d. drainpipe from the discharge of the Temperature and Pressure Relief valve to a suitable drain or catch pan with drain. The Temperature and Pressure Relief valve should be manually test-operated at least once annually to ensure that it is functioning properly. Be careful when operating the relief valve.
