Reference the Equipment Data Plate

•AquaCal 100, 120, and 155 model heat pumps have two (2) identical data plates affixed: one can be found outside the unit, on right front corner; the second data plate is located behind the front access panel, on the electrical enclosure cover.

•Refer to either equipment data plate for unit-specific electrical power supply requirements.

•Based on data plate information, size wiring, wiring devices, and over-current protection per applicable codes and standards.

•Refer to drawing below for data plate items specific to electrical installation requirements. On the installed heater data plate, the areas depicted below, numbered 1-8, will contain the information required to size the electrical service and over-current protection.

AWord Concerning Ground-Fault Protection

•The National Electrical Code (NEC) contains no standards requiring Ground-Fault Interruption protection (via GFI Circuit Breaker or otherwise) of “Fixed” or “Stationary” equipment, under article 680: Swimming Pools, Fountain, & Similar Installations, or Article 440: Air-Conditioning & Refrigeration Equipment.

•The preceding standards govern the installation of AquaCal (and other manufacturers’) heat pumps. AquaCal heat pumps are designed, and safety tested by a certified laboratory, to be installed under applicable standards detailed within the NEC.

•AquaCal does not recommend the use of ground fault protective devices in conjunction with heat pumps. Service calls, found to be due to “nuisance” tripping of ground fault devices, are not covered under the AquaCal factory warranty.
