WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Electrical wiring must be done by qualified personnel in accordance
with all applicable codes and standards. Before connecting wires,
unplug the unit or switch power off at service panel and lock service
disconnecting means to prevent power from being switched on
accidentally. Always wear safety glasses and gloves while performing
these instructions.
CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to comply with the following can cause damage.
If ducts have to go through an unconditioned space (e.g.: attic), always
use insulated ducts to prevent condensation formation inside and
outside ducts, which could cause material damage and/or mold growth.
Moreover, if fresh air to building duct and/or stale air from building
duct goes/go through an unconditioned space, the unit must be set to
operate continuously in cold conditions (below 10°C/50°F).
Continuous air movement inside ducts will prevent condensation
formation. The unit can be stopped temporarily for maintenance and/or
repair purposes in such conditions. (Refer to the main unit Installer
Manual for more details.)
