Bosch Appliances WR430-7K manual Drip Tray, Water Connections

DRIP TRAY

If the water heater is being mounted above a floor of combustible construction the drip tray (shipped loose in the carton with the water heater) must be attached to the bottom of the front cover of the water heater at the time of installation. The drip tray should be attached to the front cover, using screws provided, as shown in Figure 3.

Failure to use drip tray when installing unit above a floor of combustible construction will cause an unsafe condition and possible fire and will be in violation of A.G.A. and C.G.A. certification of the unit.

WATER CONNECTIONS

The BOSCH instantaneous water heaters are provided with two S-bend water connectors/adaptors that must be connected to inlet and outlet connections on water valve assembly, see Figure 4, below.

The purpose of the S-bend water connectors/adaptors is to provide threaded water connections that meet standards used in North America, ANSI Standard Taper Pipe Thread (1/2” NPT). The cold water supply should be connected to S-bend attached to inlet of water valve and the hot water connection should be made to S-bend attached to the outlet of water valve.

If plastic piping is to be used, a 1.5 meter (approx. 5 feet) length of metal piping must first be attached to both the cold water inlet and hot water outlet of the water heater.

Note: A shut-off valve should be placed in the cold water supply line to the heater to facilitate servicing the heater.
