Sigma AS-H50Y Heat Pump User Manual


 
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.
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.
