ELECTRICAL SYSTEM
CAUTION
The exterior of the unit must have an uninterrupted
ground to minimize the risk of bodily harm, if ever an
electrical problem develops. A green ground screw is
supplied with the control box for that purpose.
The appliance must be installed in accordance with the
current ANSI/NFPA 70 National Electrical Code, CSA
C22.1 Canadian Electrical Code Part 1 and/or local
codes.
The control system depends on the correct polarity of the
power supply. Connect “HOT” wire (H) and “NEUTRAL”
wire (N) as shown in figures 8 and 9.
A separate line voltage supply should be used, with fused
disconnect switch or circuit breaker, between the main
power panel and the unit.
Only copper wire may be used for the 115V circuit on this
unit. If wires need to be changed, the replacements must
have the same temperature resistance as the originals.
2.3
INSTALLATION OF THE
THERMOSTAT
A thermostat must be installed to control the temperature
of the area to be heated. Follow the instructions supplied
with the thermostat. Also refer to the wiring diagrams
provided with the heating/air conditioning unit. The con-
nections must be made as indicated on the following dia-
grams and the wiring diagrams, Figure 8 and Figure 9.
