Installation and Siting

Prior to installing your heat pump:-

All heat pumps are factory assembled and tested prior to delivery. Please check for any external damage especially to the evaporator fins, please diagram below. Do not be concerned about minor damage or indentations to the fins (especially where the fan unit is mounted) as it will not affect performance. If severe damage has occurred please contact your supplier immediately and do not attempt to install heater unit.

IF HEAT PUMP HAS BEEN PLACED ON IT’S SIDE IN TRANSIT THEN HEATER MUST BE LEFT

IN AN UPRIGHT POSITION FOR A MINIMUM PERIOD OF 24HRS PRIOR TO OPERATION (failing the above may cause damage to the heat pump and invalidate your warranty).

Siting

As the air flow is discharged from the top of the heat pump all units are designed to be installed outside. If unit is to be installed inside the filtration/plant room adequate ducting and ventilation must be installed. Please contact your dealer for advice.

Heater unit must be installed using plastic anti vibration pads (provided) on a solid LEVEL foundation i.e. concrete base or paving slabs. Using the plastic pads reduces vibration noise and prevents corrosion to the base of the heat pump. DO NOT PLACE ONTO SOFT GROUND I.E. GRASS. Please Note: the heat pump collects condensation from the evaporator fins and will continually discharge small amounts of condensate (water) out of the base of the unit via a drain tube. Therefore, it is recommended that the drain tube is directed to an area with adequate drainage.

Make sure that heat pump remains free of any obstructions, foliage etc. A minimum clearance is required around heater unit, please see drawing below. Make sure that easy access can be gained to service panel and plumbing connections. Do not obstruct access panel with plumbing pipework.

Multiple connections- install heat pumps 500mm apart and independently protect each unit by 20amp MCB - see also page 8, Drw.4 for plumbing detail. Make sure that heat pump grilles are not blocked by loose debris such as leaves, grass cuttings, garden

furniture etc. 3500mmMin.
