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
or cooled. 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 68.
9. If the heat pump continues to operate without water flow, contact AquaCal

1.5.a Electrical Requirements
DANGER
Failure to heed the following will result in injury or death.
l
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
WARNING
Failure to heed the following may result in injury or death.
l
The information contained in this section is intended for use by qualified electricians familiar with electrical
service-industry safety standards and methods.
l
Locate the equipment disconnect as near to the heat pump as possible. Always satisfy applicable codes and
standards.
l
Never mount power-disconnects directly to the heat pump.
l
In sizing power wiring, be especially aware of up-sizing requirements necessary due to wiring distances. Always
satisfy applicable codes and standards.
l
AquaCal
®
heat pumps are designed to use copper conductors, only. Do not use aluminum wire.
l
If multiple heat pumps are on-site, confirm that the multiple heat pump configuration has been utilized.
See
" Connecting Multiple Heat Pumps (Master / Slaved) " on page 34. This will prevent multiple heat pumps
attempting to start at the same time, causing an excessive power drop at start-up.
