Preparations before
connection
In some situations the heat pump may need extra preparations before it
is commissioned, such as moving the heat transfer fluid pipe for side
entry.
Moving the heat transfer fluid pipe for side
entry
When the heat pump is supplied the heat transfer fluid side is orientated
for a top installation. This means the pipes for heat transfer fluid in and
heat transfer fluid out run through the top of the heat pump.
If the heat pump is positioned in the house so it is difficult to install the
heat transfer fluid pipes on the heat pump from above, they can be fitted
from the side (side installation). Both the right and left-hand sides are
prepared for side installation. The following pages describe side
installation.
Side installation should be done before the heat pump is positioned in its
final installation location.
Side installation on the right-hand side
Proceed as follows to switch the heat transfer fluid pipes from top
installation to side installation on the right:
1. Remove the blanking plates (figure 1).
2. Dismantle the sensor and both heat transfer fluid pipes. The pipes
run to the top of the top panel. Heat transfer fluid in is connected by a
connector on top of the HTF pump. Heat transfer fluid out is
connected to the bottom of the heat exchanger (figure 2).
Note: The sensor fitted to heat transfer fluid out must be
dismantled first (figure 2).
3. Remove the Armaflex insulation from the heat transfer fluid pipes so
they are completely exposed (figure 3).
4. Cut the heat transfer fluid pipes so they are suitable for right-hand
side installation (figures 4 and 5). Follow the measurements given in
figures 6 and 7.
5. Solder on a copper elbow and a straight piece of copper tube. You can
use the piece left over from cutting the heat transfer fluid out pipe as
the straight piece.
Note: Do not use compression fittings to secure the elbow on the copper
pipe. Compression fittings require more space which is limited in the
heat pump.
6. Refit the heat transfer fluid pipes on the heat pump. See the result in
figure 8.
7. Refit the sensor on the heat transfer fluid in pipe. Use aluminium
tape, heat transfer compound and cable ties.
8. Slide on Armaflex insulation on both pipes and secure using
Armaflex tape. Cover both pipes well, otherwise there is a risk of
condensation.
