WATER REQUIREMENTS

Proper water quality can improve ware washing performance by reducing spotting, lowering chemical supply costs, enhancing effectiveness of labor, and extending equipment life. Local water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about local water specifics prior to installation.

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 by a water conditioner (water softener or in-line treatment). Water hardness below 4 grains per gallon also requires a water treatment to reduce corrosion. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher, reduce detergent usage, and reduce corrosion of metallic surfaces in the booster water heater and dishwasher.

Sediment, silica, chlorides, or other dissolved solids may lead to a recommendation for particulate filtration or reverse osmosis treatment.

If an inspection of the booster reveals lime build-up after installation, in-line water treatment should be considered, and, if recommended, should be installed and used as directed. Contact your Hobart Service office for specific recommendations.

PLUMBING CONNECTIONS

WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY, AND PLUMBING CODES.

The inlet and outlet water connections are 3/4 inch NPT. The inlet water supplied to the booster heater must be a minimum of 110°F. Do not connect to cold water supply. Recommended flowing water pressure to the booster heater is 20 psig. Minimum is 15 psig; maximum is 25 psig. If a water pressure regulator is used to regulate the water pressure, adjust to maintain 20 psig at the dishwasher. A water pressure regulator, pressure gauge, and water shock absorber are provided by Hobart when ordered in an optional accessory Water Hammer Arrestor Kit.

Install a suitable water hammer arrester between the booster heater and dishwasher (Figs. 6 and 7).

A 3/4 inch NPT drain valve is provided underneath the booster heater to allow the tank to be drained, if needed during servicing. This drain connection may be plumbed to a suitable open floor drain.

The Temperature and Pressure Relief Valve is located at the rear of the booster heater. Install a pipe from the discharge connection on the Temperature and Pressure Relief Valve to a suitable drain or catch pan with drain. The discharge connection on the Temperature and Pressure Relief Valve is 3/4 inch NPT on IB57 and IB140; the connection is 1 inch NPT on IB235 and IB290. Refer to the Tag on the Temperature and Pressure Relief Valve for additional drain installation instructions.

The Temperature and Pressure Relief Valve should be manually operated at least once annually to make sure that the valve mechanism is still functional. Use care when operating the relief valve. Follow instructions on the tag located on the Temperature and Pressure Relief Valve to avoid contact with hot water discharge and to prevent water damage from operation of the valve.

Repair or alteration of the Temperature and Pressure Relief Valve in any way is prohibited by national safety standards / local codes.

If the Temperature and Pressure Relief Valve discharges occasionally or periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or the local plumbing inspector regarding how to correct this situation. DO NOT plug the relief valve or install a shutoff valve in the discharge drain line.
