The distance from side panel to wall should be no less than 150mm. 2. When the unit is to be installed low on the wall, the distance from the bottom of unit to floor should ideally be no more than 300mm and no less than 100mm. The distance from side panel to wall should be no less than 150mm. 3. The wall that supports the unit must be strong enough to withstand the weight of unit. The fixings should be chosen so as to be suitable for the type of wall particularly hollow walls. It is the installer s responsibility to check carefully 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 0.2m range of the air outlet area, otherwise it 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 - 6 -
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 ). - 7 -
Indoor Outdoor Fig6 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, the drilling 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. 3.3.2 Exhaust Air Duct Spring and Exhaust Cover Assembly Drill the hole accurately, clean out and then put exhaust air duct inside the hole.
