4.4.b General Requirements
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.
In sizing power wiring, be especially aware of up-sizing requirements necessary due to wiring
distances. Always satisfy applicable codes and standards.
Multiple heat pumps installed at the same site may benefit from automatic sequencing controllers to
avoid excessive power drops at start-up. An "ASC" controller is available by calling AquaCal
AutoPilot Customer Support. See "Available Accessories" on page 39 for more information.
4.4.c Grounding and Bonding
Follow local code requirements for properly grounding and bonding heat pump equipment.
4.4.d Surge Suppression
The use of approved commercial surge protectors is strongly recommended.
4.4.e Sizing the Electrical Service
There are two (2) identical data plates on the heat pump; one located on
the outside right front corner and one behind the front access panel of
electrical enclosure.
Refer to equipment data plate (Figure 26) for specific information required
to size electrical service and over-current protection of heat pump. Sizing
is based on data plate information, wire size, wiring devices, and over-
current protection per applicable local codes and standards.
