Installation Method
The ThermaQ Midi electric water heater can be used for hand washing or
cleaning in a kitchen, etc. and it can be installed above or under the sink.
INSTALLING THE UNIT
Using the brackets and mountings provided please mount your unit on the wall, please take
into account the following points when choosing where to mount your water heater.
1. The wall must be strong enough to take the weight of not just the water heater, but
the water it holds as well, wherever possible we would recommend securing onto
an external brick wall Fig. 2.
2. The unit should be located in a position as close to the outlets as possible, this
reduces the amount of pipework between the heater and the outlet thus reducing
heat loss across the pipework..
3. Ensure the water heater is in the correct orientation, the oversink model should
always have the connections at the bottom of the unit and the undersink module
should always have the connections on the top of the unit Fig. 1.
