15.1. Warning and caution
WARNING
Electrical work should be done by a dealer, contractor or technician with certifications
required by laws and codes in accordance with "Engineering Standards for Electrical
Installation" and supplied installation manuals. If the power circuit lacks capacity or has an
installation failure, it may cause a risk of electrical shock or fire.
• Follow the local and national code requirements when wiring the PAA unit and connec-
ted outdoor units and controls.
• Install the unit in a manner that prevents direct contact between any of the control circuit
cables (remote controller, transmission cables) and the power cable outside the unit.
• When sizing wire and completing electrical connections during installation, please follow
local codes and standards. Secure the connections so that the outside force of the cable
is not applied to the terminals.
• Some cables (power, remote controller or transmission) above the ceiling may become
damaged by accident or by animals. Use conduit as much as possible to prevent dam-
age.
• Never connect the power cable to leads for the transmission cables. The cables will
break.
• Be sure to connect control cables to the indoor unit, remote controller and the outdoor
unit.
• Perform wiring in compliance with the safety regulations detailed in UL 1995.
• Before installation, please ensure that the furnace is properly grounded.
WARNING
Be sure to ground the PAA unit cabinet and control box. Do not connect the grounding
cable to any gas pipe, water pipe, lightening rod or telephone earth cable. Incomplete
grounding may cause a risk of electrical shock. If the supply cord is damaged, it must be
replaced by the manufacturer, service personnel or licensed persons in order to avoid a
hazard.
Specifications are subject to change without notice.
