WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in
personal injury or death.
•
The unit cabinet must have an uninterrupted or
unbroken ground to minimize personal injury if
an electrical fault should occur. The ground may
consist of electrical wire or metal conduit when
installed in accordance with existing electrical
codes.
•
The appliance shall be installed in accordance
with national wiring regulations.
•
Before performing service or maintenance, be
sure main power switch is turned OFF.
CAUTION
All wiring and connections must comply with NEC,
CEC, local codes.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in
damage or improper operation.
•
Unit failure as a result of operation on improper
line voltage or excessive phase imbalance
constitutes abuse and may cause damage to
electrical components.
•
Wrong wiring may cause a burn-out of some
electrical parts.
•
Do not damage or scratch the conductive core or
inner insulator of the power and inter-connecting
wires when peeling them.

Connect the system interconnection (indoor to
outdoor) wires to the identical terminal numbers on
the terminal block of each unit.
Incorrect connection may cause a failure.
1. With the front panel removed the electrical control
box is exposed at the top right corner of the unit.
2. Terminate the field wiring conduit (if used) at the
conduit connection holes provided.
3. Route the field power wires and the system
interconnection wires as shown on the following
pages. Terminate the wires at field wiring terminal
blocks located immediately below the electrical
control box.
