INITIAL START-UP - (Electronic Control Systems Only) After completing the electrical and piping connections to the pool heater, follow the procedures outlined below to insure that the pool heater is functioning properly. Before proceeding, MAKE CERTAIN there are no air or water leaks in any plumbing connections or piping and water flow is within the proper flow rate ranges: MODEL PE 42: MODEL PE 52: 20 gpm min. - 70 gpm max. 30 gpm min. - 75 gpm max. NOTE: Damage caused by flow rates outside this range will void your warranty. 1.Check to see that pool heater thermostat is in the "OFF" or "Standby" position. 2.Apply power to the pool heater by plugging in the fused disconnect block or moving the circuit breaker to the "ON" position. 3.With the pool filter pump operating, set the pool heater thermostat to the desired temperature. 4. When the pool heater starts, disconnect power to the pool filter pump. The pool heater should instantly cease operation. IF THE POOL HEATER CONTINUES TO OPERATE, THE WATER PRESSURE SWITCH MUST BE ADJUSTED (see page 30). If the pool heater ceases operation when power to the filter pump is disconnected, the water pressure switch adjustment is correct for this installation. 5. Restore power to the pool filter pump. There is a five (5) minute time delay period that will prevent the heat pump from restarting. Wait for a few minutes for the heat pump to restart. If the restart doesn't occur, refer to the troubleshooting section. 6. When the unit starts, visually check the fan is operating and air is being discharged upward from the unit. Listen for the sound of the compressor starting. If you are not familiar with, or are unsure of exactly what sound the compressor makes, take an amp reading around one incoming power wire near the contactor. The amp reading should be 20 amps or above when the compressor is running (even at low ambient and/or water temperature.) 7. If both the fan and compressor are operating, allow the pool heater to operate for 10 - 15 minutes in order for system pressures to stabilize. 8. Using a thermometer, check to see if the discharge air is 5°F - 128F cooler than the ambient air temperature. If discharge air does not have a noticeable temperature change, refer to troubleshooting section. 30

INITIAL START-UP
-
(Electronic Control Systems Only)
After completing the electrical and piping connections to the pool heater, follow
the procedures
outlined below to insure that the pool
heater is functioning properly.
Before proceeding,
MAKE CERTAIN
there are no air or water leaks in any plumbing connections
or piping and water flow is within the proper flow rate ranges:
MODEL PE 42:
20 gpm min. – 70 gpm max.
MODEL PE 52:
30 gpm min. – 75 gpm max.
NOTE:
Damage caused by flow rates outside this range will void your warranty.
1.
Check to see that pool heater thermostat is in the "OFF" or “Standby” position.
2.
Apply power to the pool heater by plugging in the fused disconnect block or moving the circuit
breaker to the “ON” position.
3.
With the pool filter pump operating, set the pool heater thermostat to the desired temperature.
4.
When the pool heater starts, disconnect power to the pool filter pump. The pool heater should
instantly cease operation
. IF THE POOL HEATER CONTINUES TO OPERATE, THE
WATER PRESSURE SWITCH MUST BE ADJUSTED (see page 30)
. If the pool heater ceases
operation when power to the filter pump is disconnected, the water pressure switch adjustment is
correct for this installation.
5.
Restore power to the pool filter pump. There is a five (5) minute time delay period that will
prevent the heat pump from restarting. Wait for a few minutes for the heat pump to restart. If the
restart doesn’t occur, refer to the troubleshooting section.
6.
When the unit starts, visually check the fan is operating and air is being discharged upward from
the unit. Listen for the sound of the compressor starting. If you are not familiar with, or are unsure of
exactly what sound the compressor makes, take an amp reading around one incoming power wire
near the contactor. The amp reading should be 20 amps or above when the compressor is running
(even at low ambient and/or water temperature.)
7. If both the fan and compressor are operating, allow the pool heater to operate for 10 - 15 minutes
in order for system pressures to stabilize.
8. Using a thermometer, check to see if the discharge air is 5
°
F - 12

F cooler than the ambient air
temperature. If discharge air does not have a noticeable temperature change, refer to troubleshooting
section.
