RHEEM THERMAL AIR SOURCE HEAT PUMP INSTALLATION, MAINTENANCE & SERVICE MANUAL
For validity of warranty, installation must be carried out by registered trade person.
1.1 Installation Guidelines
• Heating efficiency and output increases with the rise in entering air temperature, as
such full advantage should be taken for direct sunlight, typically with evaporator coil
facing north-west or facing a heat source like boiler room, etc.
• Locating the unit close to other system equipment like the pump, tank, etc. will minimize
friction and heat losses.
• Free circulation of air across the coil, requires no obstructions on the intake or fan
discharge of Heat Pumps. Do not position the unit with any intake side closer than
1,000mm to adjacent wall, fences, hedges, etc. Ensure that walls, eaves, etc. do not
obstruct the release of discharge air such that this may recirculate in the incoming air
stream of the unit.
• Service access is required at both ends of the heater. Allow a minimum 850 mm service
access at the compressor end if possible for units up to 80 kW. For units 100 kW and
above 1000 mm access at the compressor end is required.
• Where multiple heat pumps are to be installed, follow the required minimum clearance
indicated in the heat pump catalogue.
• The Heat Pump requires a concrete slab. Rubber mounts shall be installed between
the unit and slab.
• Local building authorities should be consulted for regulations concerning minimum
installation distance from pool or other amenities.
• Units to be used in areas having highly corrosive atmosphere, must be specified at time
of ordering.
• Consideration should be given to the operating noise, wherever possible the exhaust
should be directed away from the occupied areas.
• To ensure proper drainage of the Heat Pump, make sure that the unit is located at a
slightly tilted angle with the drain on the downhill side of the unit. This can be done by
making the concrete slab slightly higher at one end or lifting one end of the unit by
rubber mounts.
