• The pipe should be prevented from exposure to the elements, as this may contribute to freezing

issues. The condensate pipe must run through the base panel and underground to the drain. Freezing

of this pipe due to incorrect installation can result in irreparable damage and void warranty.

• Approximately 2 litres of condensate water are drained from the system every time a defrost cycle

occurs (approximately once every hour in cold and humid weather). Therefore, it is essential that the

condensate pipe is fed into a rain water drain or soak away to allow for safe disposal of the excess

water, away from footpaths or patios.

• The removal of condensate must be secured and the condensate pipe must be kept free from debris

and frost.

• The condensate pipe should not run into sewer pipe as fumes may travel into the heat pump and

cause corrosion to the evaporator coil.

4) Inserting the ﬁxing bolts

Once the holes for the xing bolts are drilled, place the heat pump back onto the plinth and x in place

using the M10 bolts supplied in the installation pack.

5) Positioning and Fixing Indoor Components

The controller and thermostats should be installed on internal walls in living area to reect the correct

room temperature, and away from direct sunlight, drafts (windows and doors) and heat emitters.

3.1.1 Temperature Control Devices

• The controller/user interface that is supplied with the Dimplex A-Class heat pump is used as a

heat pump controller as well as a space heating and domestic hot water (DHW) controller.

The preferred option is to use the user interface as a room temperature control device.

• The user interface and room thermostats should be installed indoors in a location that is out of

reach of children, but where the LCD display can be easily seen (usually 1.2m – 1.7m from the

oor).

While only one user interface is currently available per system, there are additional options

of either temperature probes or mechanical thermostats, which can be used to control the

temperature in up to four zones.

• Mechanical thermostats provide less control over the heating system, while the temperature

probe option allows the heat pump to sense changes in demand and adjust accordingly. The

temperature probe option is generally recommended over the mechanical thermostat option.
