CAC CASSETTE EVAPORATOR INSTALLATION INSTRUCTIONS
Electrical Wiring
The standard unit Voltage is 208/230V (60Hz, 1Ph). Check the unit’s rating plate for your models’ electrical requirements.
•The wires should be capable of carry- ing the maximum load current under
•Avoid large Voltage drops on cable runs, particularly in low Voltage wir- ing.
•The correct cable size must be used to ensure a Voltage drop of less than 1 Volt in the control wiring.
•Once the refrigeration pipe work is complete, the electrical supply can be connected.
•Low Volt wiring must be at least 18 awg.
All wiring should be in accordance with the National Electric Code (NEC) and the local building codes.
1.Make sure power is off.
2.Inspect the existing wiring for any de-
ficiencies such as cut or frayed wires. Replace if any such wiring if found.
3.Remove the 4 screws securing the control box cover.
5.The rating plate is located on the outside of control box cover (see Low Volt Inter- connecting Wiring section for location of wiring diagram).
6.Check the unit rating plate for circuit ampacity and breaker or fuse size. Use only HACR type breakers. Select the proper wire for the ampacity rating.
7.Each unit must have a separate branch circuit protected by a fuse or breaker. Refer to the unit rating plate for the proper wire and breaker or fuse size.
8.It is also recommended that a local dis- connect switch be connected within 3’ of the unit. In some areas this may be a code requirement.
4.lide cover p and out to remove.
