2.  INTRODUCTION

A

WARNING:

  This  heat  pump  pool  heater  is  an 

electromechanical  machine  that  incorporates  a 

pressurized  refrigerant  gas  in  a  sealed  system.  ONLY 

trained and qualified service personnel are authorized to 

install or service this equipment. Without proper training 

and knowledge of such equipment, any attempt to install 

or service the unit could result in serious injury or even 

death.

This  manual  contains  important  information  on  the  use, 

maintenance  and  troubleshooting  of  your  new  heat 

pump  pool  heater.  This  unit  must  be  properly  installed, 

maintained and operated for optimal performance. 
This heater is an extremely efficient, economical machine 

designed  specifically  for  heating  swimming  pools.  It  is 

similar in design and operation to a typical residential air 

conditioning system. The unit employs a hermetic motor/

compressor  operating  in  a  refrigeration  cycle  to  extract 

heat from ambient air and deliver it to the circulating pool 

water.
All heat pump pool heaters have a lower BTU/hr heating 

capacity than a gas-fired or oil-fired heater for the same 

pool and will have to operate more hours per day to keep 

the pool at setpoint.  It may operate up to 24 hours a day 

at certain times.  It is designed to do so.  Even with long 

runtime hours, it will heat the pool at less cost than other 

heaters using fossil fuel.
Since evaporation is the main cause of heat loss from a 

pool, keeping the pool covered whenever it is not in use will 

greatly reduce the cost of keeping the pool heated.  Even 

during warmer weather, Raypak recommends keeping the 

pool covered at night.

NOTE:

 Hurricane tie-down brackets, tie-down screws, 

2  x  union  halves,  2  x  45-degree  PVC  elbows,  the 

printed warranty and the I&O manual are located in an 

accessory box mounted on the pallet beside the heater 

inside  the  packaging.    DO  NOT  throw  away  the  box 

without removing all the contents.
