WARNING
Failure to heed the following may result in injury or death.
l
Water Pressure Switch adjustment procedure to be performed by experienced service personnel only; procedure
must not be attempted by individuals lacking adequate electrical and mechanical experience.
NOTICE
Failure to heed the following may result in damage to equipment.
l
If the heat pump continues to operate after a water pressure switch adjustment, deactivate equipment and perform
additional troubleshooting.
1. Remove heat pump access panel.
2. Locate the water pressure switch. It will be outside and along
the bottom edge of the electrical enclosure. The exact location
varies by model.
3. Activate the filter pump.
4. Apply power to heat pump.
5. Slowly rotate the adjustment wheel on the switch. Keep
turning the wheel until the heat pump indicates it is receiving
water. The display will no longer indicate "
NO POOL/SPA
WATER FLOW
".
6. Deactivate filter pump. If correctly adjusted, the heat pump
will deactivate and the display will show "
NO POOL/SPA
WATER FLOW ".
7. Re-install heat pump access panel.
8. If the heat pump continues to operate without water flow, the installation of a grid flow switch may be required.
l
This can become necessary if the heat pump is installed below the elevation of the body of water to be heated.
The standing pressure from the water can cause the water pressure switch to activate when the circulation
pump is off. Therefore a water
flow switch must be used in place of a water pressure switch to determine if
incoming water is being sent to the heat pump. See " Grid Flow Switch (# 0040S) " on page 67.
9. If the heat pump continues to operate without water flow, contact Leisure Temp.
