3.2.1 In order to get the best operation and to avoid any risks or failure, positioning of the
appliance should be in accordance with following diagram (Figure 4):

- 6 -
1. When the unitis to be installed high onthe wall, the distance frombottomof unit to floor should
be no less than 2mand no more than 3m. The distance fromside panel to wall should be no
less than 150mm.
2. When the unitis to be installed low on the wall, thedistance fromthe bottomof unit to floor
should ideally beno more than 300mmand no less than 100mm.The distancefromside panel
to wall should be noless than 150mm.
3. The wall that supports the unit must be strong enough to withstand the weight of unit.The
fixings should be chosenso as to be suitable for the type of wall – particularly hollow walls. Itis
the installer’s responsibility tocheckcarefully and use suitable fixings for the appliance.
4. Leave enough space around the unit for operation and maintenance.
5. Keep the area around air inlets completely clear to avoid any restriction of air flow, especially
within 0.2mrange of theair outlet area, otherwiseit will cause abnormal noise from the unit
during operation.
3.2.2 The chosen installation wall must be an outside wall.
Note: Before starting work ensure the correct positioning for the unit. Double check the
wall and confirm the wall is suitable to drill through. Take particular care that the wall
does not contain other services such as lights, wiring, water or gas pipes etc.
3.2.3 Before unit installation, it is necessary to double check the room size for the unit and
precisely calculate the heat load in summer and cooling load in winter that the heat pump
unit will have to manage for the room.
Precise calculation will optimize the unit function and help understand which potential
Fig4

- 7 -
factors would influence the unit performance. In order to make sure the unit has the
maximum possible effect, the following are recommendations:
- Keep the room as well sealed as possible, i.e no open windows and minimum
ventilation necessary.
- Do not use high power electrical appliances in the room if cooling is required.
- Keep direct sunshine out of the room if cooling is required.
3.3 INSTALLATION
3.3.1 Drill the hole through the wall
Use suitable tools (for example a core drill and large percussion/impact drill) that will help
make installation as efficient as possible, avoid excessive damage to the wall and avoid
inconvenience to the user or others.
.
Drill the wall according to instructions below.
1. Stick the installation drawing (Figure 5) to the correct position on wall with adhesive tape, the
position should be in accordance with the dimensions given in section 3.2 Positioning the
appliance.
Fig5
2. Mark the centre point of each hole to be drilled by using a pen, small drill or punch.
3. Use masonry drill to make holes - Note: Hole position should comply with drawing. For small
holes use φ13mm drill, drilling approximately 60mm deep. For the large holes, pilot drill and
then open out to φ165mm right through the wall. The large holes must have a downward
inclination of 3-5 degrees, to avoid water flow backwards. (Figure 6 ).

During the drilling operation make sure that all debris falling outside of the property does
not fall anywhere that may cause a danger to persons or property, particularly is installing on
the upper floors of a building. When the drill is less than 50mm from the outside, reduce
drilling speed and pressure to reduce risk of large amounts of breakthrough debris. If
accessible, thedrilling can re-commence from outside of the wall to give a very accurate and
clean finish to the outside wall edges.
If the wall is not hard or strong enough, reinforce it by other methods such as a metal wall plate
etc.
Warning: Any resultant damage due to improper installation and operation is not the
responsibility of the manufacturer. Operation and installation according to instruction manual is
therefore essential to avoid any unnecessary damage to persons or property.
