Installation Instructions

• Check the mounting of the water heater. The model HT-BVU-D has to be installed horizontally against the wall with the incoming water pipe pointed upwards for de-aeration. The outgoing pipe is placed in line with the heater (see directional arrow).
• When positioning the heater sufficient space must be taken into consideration for installing replacement heating element units.
• It is preferred to install the water heater on the pressure side of the circulation pump.
• Check that the working pressure does not exceed the values mentioned on the name plate (maximum 6 bar).

Electrical Connection

• The water heater is pre-wired and tested. The primary connections must be performed according to the electrical diagram supplied with the heater.

Putting Into Operation

• Check whether the voltage present is similar to the voltage on the name plate.
• Check the electrical connections for tightness. Electrical connections can loosen during transport.
• The heater must be properly de-aerated.
• Check whether the connection housing is free from moisture and dirt.

Thermostats

• The control thermostat has to be set to the desired water temperature.
• The maximum safety thermostat can be reset after the sensor has had time to cool down to a level below the set temperature.

Switching On

• The water heater must never be switched on without the water flow being switched on.

Switching Off

• After the water heater has been switched off it is preferable to allow the systems circulation pump to keep running for a number of minutes. This will prevent the remaining heat in the elements to build up inside the heater which can cause the safety thermostat to function.

Maintenance And Cleaning

• If the medium is polluted the inside of the water heater can be filled with drab and/or particles that can build up a layer on the heating elements. This will cause the heating elements to be insulated causing them to function improperly which can result in a burn out of the heating elements. It is advised to remove any depositions of dirt from the elements on a regular basis.
