  • Page 3: How A Heat Pump Works

    How a Heat Pump Works Hayward Heat Pumps take heat from the environment and use it to heat your pool water. During heat pump operation, liquid freon from inside the unit is pumped through the system (A) and is turned into a heated gas. This happens when heat is taken from the surrounding air (B) as it is drawn through the evaporator by the fan.

It will provide you with descriptions of button functions and setpoint programming.
  • Page 9 PST-5 Heat/Cool The PST-5 is an upgrade of the PST-4 with the addition of an AUTO function. This allows the heat pump to heat or cool the water automatically to maintain the setpoint. The PST-5 also has an optional Time Clock Override (TCO-This feature must be connected by an electrician to operate.) Read the instructions for the PST-1 and PST-4 fully before continuing.

    Means of draining condenser and rainwater. Insulation of long water lines (over 25 ft.) from heater to pool. The installation of the unit in a fully enclosed area (i.e. garage, shed, etc.) is not recommended. Consult HAYWARD for indoor pool application analysis.

  • Page 11: Clearance

    Clearance A minimum of two feet of clearance from walls, shrubbery, equipment, etc. is required around the entire pump circumference. This allows for ample air intake. No less than 6 feet clearance above the heat pump is required to prevent re-circulation of air. We recommend not placing the unit underneath eaves, decks, or porches, as this causes recirculation of discharged air.

  • Page 12: Other Precautions

    Heat Pump Pool / Spa Heater Owner’s Manual Other Precautions The heat pump should not be placed near sprinkler systems, especially those where fertilizer is added. This is very corrosive and, over time, will severely damage the unit. If you live in an oceanfront area, the heat pump should be placed out of direct spray of sand and salt.

  • Page 13: Efficient Practices

    Efficient Practices Using A Pool Cover POOL COVERS ARE STRONGLY RECOMMENDED. A pool loses heat in several ways but testing shows that evaporative cooling (the cooling effect created by water evaporating from the surface of the pool) accounts for approximately 75% of a pool’s heat loss. However, if a pool is covered when it is not in use, most evaporative cooling can be prevented.

    Heat Pump Pool / Spa Heater Owner’s Manual Time Clock Override (TCO) Function Purpose: This function provides another way to maintain pool temperature. Most pool systems use a time clock to control the pool’s filter pump. The time clock may have the filter pump off for several hours at a time. Since the filter pump must be flowing water through the heat pump for heating of the water to occur, the Time Clock Override (TCO) function allows a user to control the pool filter pump by temporarily bypassing the time clock.
