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).

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
with water.
2. Check all pipe connections for leaks.
3. Make sure the temperature/pressurerelief valve discharge
is not blocked.
4. 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.
Form No. EBOOSTERBWM-1009
DO NOT turn on power to the booster water heater until
tank has been filled with water and all air has been vented
through dish machine rinse nozzle. The heating elements
will burn out in seconds if operated when they are not
immersed in water.
