HOT WATER CONNECTION TO WATER HEATER.
Refer to Technical Sheet for position of connection. The outlet connection is 18 mm (3/4"
BSP) MALE thread, and requires an isolating union to allow for removal of the unit.
Keep the pipe lengths to a minimum, and make sure that the pipework is well insulated as
correct performance of the appliance is dependent on properly insulated pipework.
DO NOT FIT ANY VALVES OR RESTRICTORS TO THE OUTLET OF THE WATER
HEATER.
DO NOT FIT ANY OBSTRUCTION TO THE PRESSURE RELIEF LOCATED ON THE
HOT WATER OUTLET CONNECTION.
After purging the air from the system using the hot water supply taps, remove the water inlet
strainer located on the cold water supply inlet connection. Remove any debris from the filter
and replace. When replacing the filter, do not over-tighten the “O” ring seal.

The appliance is equipped with a 1.7 metre cable with a three pinned earthed plug
to be connected to a 240V, 50Hz supply. The electrical rating of the appliance is
0.4 Amps
The appliance requires a 240V in Australia and 230V in New Zealand, 50Hz
weatherproof plug installed in a protected position adjacent to the appliance.

PRE-SET TEMPERATURE
The Bosch water heaters are factory pre-set to operate at 55°C (or 50°C on 50
degree model) without temperature selector pads. The pre-set temperatures can be
altered to 60°C or 75°C, (or 42°C on 50 degree limited unit) by changing the setting
of the CPU or by using the temperature bridges supplied. Refer to page 13 for
details.
The appliance can also be fitted with temperature selector pads, available as an
accessory item. When fitted, the hot water will be delivered at the temperature
displayed on the selector pad.
There are two versions of remote controls available, the 66 series which has bath fill
alarm and the 67 series which has bath fill stop.
The two different series must never be connected to the same water heater.
The Bathroom controller cannot be used as a sole controller.
There is a Main, Bathroom and Ensuite control available in each series, never
connect more than one of each control type to the water heater (except an extra sub
controller as the fourth controller.)
Only one of each type can be connected to the appliance.
