4.6.3 Installation of the heat pump
Ideally the heat pump should be placed next to a wall allowing easy access to the ground array manifold.
Any pipes internal to the building must be insulated with vapour barrier insulation such as Armaflex.
i.
Remove the top of the shoebox heat pump. This is connected via magnets so a short sharp pull of
the top forward and up will release this.
ii.
This will now expose the pipe connections and front panel to access the shoebox electronics
(See
below Fig 10).
iii.
Position the appliance on a firm, level and substantial concrete base that will absorb vibration .
iv.
Using the adjustable feet, level the unit.
v.
Ensure the heating distribution system has been thoroughly purged of any debris.
vii.
Connect the cold feed, ground feed & return pipes , feed & return pipes from the underfloor
heating manifold ,(which must be connected the correct way round) according to the Illustration
below. Flexible hoses are provided with the shoe
box to aid in the installation. These hoses should
not be directly connected to the connections on the heat pump but used between pipe (i.e. an
elbow) connected at the heat pump and the distribution systems (see Fig 11). The flexible pipes can

be fitted in any orientation and work best when slightly curved. The
reason for using flexible pipe
is that the heat pump is suspended on anti
-
vibration mounts, so the
connections must also be
flexible.
Ensure there are no kinks within the flexible pipe.
Using the
stickers provided ensure the
flow and return connections are indicated on the manifold.
