Electrical; Electrical Requirements - Aquacal Heatwave Superquiet TropiCal Installation Manual

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. Exact location
varies by model.
3. Activate 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 display the FLO code.
6. Deactivate filter pump. If correctly adjusted, the heat pump
will deactivate and the display will show the FLO code.
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.
This can become necessary if the heat pump is installed below the elevation of the body of water to be heated
l
or cooled. The standing pressure from the water can cause the water pressure switch to activate when the
circulation pump is off. Therefor 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 29.
9. If heat pump continues to operate without water flow, contact AquaCal

1.4.a Electrical Requirements
WARNING
The information contained in this section is intended for use by qualified electricians familiar with electrical
l
service-industry safety standards and methods.
Locate the equipment disconnect as near to the heat pump as possible. Always satisfy applicable codes and
l
standards.
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
l
satisfy applicable codes and standards.
®
AquaCal heat pumps are designed to use copper conductors, only. Do not use aluminum wire.
l
Multiple heat pumps installed at the same site may benefit from automatic sequencing controllers (ASC) to avoid
l
excessive power drops at start-up. See "Available Accessories" on page 28.
Failure to heed the following may result in injury or death.
