Bradford-White Corp MAGNUM Series Commercial Electric Booster Electrical All Sizes and Voltages

INSTALLATION

Outlet

1. Using a 3/4″ union and piping, connect the booster water heater outlet to the commercial dish machine sanitizing rinse pipe connection.

NOTE: The red mark on the inlet and outlet water pipes of Magnum Series units must remain in the top most position.

NOTE: Make sure the connection is made to the final rinse and not to the wash tank.

2. Install a temperature/pressure gauge in the outlet line. The temperature sensing element must be in the water stream and the gauge must be mounted upright. Water temperature at the outlet should be 185°–190°F (85°–88°C).

Figure 9. Alternate Temperature/Pressure Gauge Installation

NOTE: Bradford White recommends installing an		optional
	shock absorber in the outlet line as close as possible
	to the commercial dish machine solenoid rinse valve.
	The shock absorber softens the water hammer caused
	by automatic dish machine valves.
Plumbing Installation Inspection
1.	Close drain pipe shut-off valve and fill booster water heater
2.	with water.
	Check all pipe connections for leaks.
3.	Make sure the temperature/pressurerelief valve discharge
4.	is not blocked.
	Vent air from the booster tank before turning on the unit by
	opening the temperature/pressure relief valve as well as
	running the dish machine through several cycles.
