INSTALLATION
- Ensure that sufficient air breaks and traps are provided to
avoid water being retained within the indoor unit. Otherwise,
the condensed water could leak from the indoor unit.
- For gravity drains ensure fall is sufficient, the pipework is
adequately supported and does not sag and bends are of
large radius to avoid blockages.
- If the water pipe is runs outdoors, ensure that it is
insulated against freezing.
- If the condensed water pipe runs through an un-heated
room, fit thermal insulation.
- Avoid installing the condensed water pipe with a rising
bend (see Figure 9.1).
Fig. 9.1 Avoid rising bends
- If the drain is run to a tank or butt, avoid installing the
condensed water pipe with its free end submerged in
water (see Figure 9.2).
Fig. 9.2 Avoiding submerging the end.
- Do not allow the drain line to be kinked or flattened which
could reduce the flow of water from the indoor unit (see
Figure 9.3).

- For drain pipes run to ground level outside, install the
condensed water pipe in such a way that the distance of
its free end from the floor is at least 5 cm (see Figure 9.4).
Minimum distance from the floor.

- Install the condensed water pipe in such a way that its
free end is kept away from unpleasant odours, such as
from open drains, to ensure that they are not drawn back
into the unit (see Figure 9.5).
