Page 20 4.3.b In-Line Chlorine Feeders Place in-line chlorinators as far downstream from the heat pump and as low in elevation as possible. If an erosion type feeder is used, always install a Hartford Loop to protect internal heat pump components. 4.3.c Water Connections to Heat Pump Connection to site plumbing is made via PVC solvent cement to the female slip socket of the plumbing unions.
Figure 24 and Figure 25. Follow the adjustment procedure for the appropriate switch. Should adjustment of water pressure switch prove unsuccessful, contact AquaCal AutoPilot Technical Support; site-specific factors may require the installation of an external flow switch.

In this orientation rotate top of adjustment 2) Slide tab left to unlock the adjustment wheel TOWARD you to decrease water pressure required to start heat pump.
Locate the equipment disconnect as close to the heat pump as possible. Always satisfy applicable codes and standards. AquaCal AutoPilot heat pumps are designed for copper conductors, only. Do not use aluminum wire. Never mount a power-disconnect directly to the heat pump.
Page 24 4.4.f Verify Transformer Tap Voltage settings must be confirmed and set correctly on the heat pump depending on the measured voltage found at the installation site. If an incorrect voltage is set on the heat pump, it may not start or it could possible cause damage to heat pump components.
Page 25 1. Attempt to turn heat pump on by adjusting thermostat to call for heat. If more than one heat pump is onsite, turn them all on. Final adjustments must be made with all heat pumps running. 2. Locate the phase rotation monitor in the electrical box of heat pump. a) If a standard phase monitor is found (Figure 28), adjustment is not needed.
