SECTION 2 

COMMISSIONING 

 
The Rheem Thermal heat pump is fully charged with refrigerant.  The following  checks should be 
carried out: 
 
1.  Installation and operation instructions should be read prior to commissioning. 
 
2.  The unit should have unrestricted supply of fresh air to the coil and exhaust air removed from 

closed in areas. 

 
3.  The unit should stand on a firm level base but noting that it should have a small incline towards 

the condensate drainage inbuilt to the case (plumbing end). 

 
4.  Noise should be directed away from living areas. 
 
5.  Water connected correctly as indicated. 
 
6.  Any chemicals are introduced downstream of unit. 
 
7.  Condensate drain runs to waste. 
 
8.  Unit is wired correctly. 
 
9.  Unit is not to be started without flow of water. 
 
10.  The thermostat is set to the required parameters. 
 
11.  Three phase fans and scroll compressors are running in correct rotation. 
 
 
 

SECTION 3 

OPERATION 

 
1.  The Heat Pump unit has an internal thermostat, located at the control panel, which maintains the 

outlet water at the selected temperature.  The normal operating temperature range is 25

C to 

40

C. 

 
2.  Select a suitable temperature about 38

C for spa and 28

C for pools. 

 
3.  The unit is fully automatic and after commissioning, the operation of the unit will be triggered by 

water flow and the set temperature parameters. 

 
4.  In low ambient temperature ice may form on the evaporator coil.  If this occurs the machine will 

automatically go into defrost operation. 

 
5.  The  unit  can  be  controlled  via  time-clock  through  water  pump.    The  unit  has  in-built  water 

flow/pressure switch and will sense water flow to start unit. 

 
6.  Running Time ~ The Heat Pump is controlled by a thermostat which will switch the unit off when 

the set temperature is reached.  The running time will vary with  the weather, amount of wind, 
length of time the pool cover is off and the pool usage.  As this is an automatic operation, manual 
switching  is  not  necessary,  i.e.  allow  the  Heat  Pump  to  monitor  the  pool  temperature.    Long 
periods of being switched off will make the 

unit’s job more difficult, especially when a constant 

temperature is desired. 

 

7.  Backwashing 

– Always isolate the unit electrically prior to backwashing. 

 

8.  Valve Setting 

– Do not adjust any valves whilst the pump is running. 

 
Note  that  the  initial  temperature  rise  for  swimming  pool  heating  may  seem  slow  but  the  unit  is 
probably working.  Heat pumps have a much lower KW/MJ per hour heat output capacity than gas 
and will need to operate for more time to deliver the same heat transfer.
