INSTALLING ACCESSORIES
WARNING
WARNING
!
Electrical shock hazard.
Turn OFF electric power at fuse box or service
panel before making any electrical connections and
ensure a proper ground connection is made before
connecting line voltage.
Failure to do so could result in property damage,
bodily injury or death.
8.1)
Electronic air cleaner (E.A.C.):
Wire leads are provided to direct 115 volts @ 0.5 Amp maximum to an
electronic air cleaner (E AC). Power will be available to the E.A.C when
E.A.C switch is on or during heating speed blower operation. Wire the
electronic air cleaner as indicated in the wiring diagram (figures # 4.1,
# 4.2 and # 4.3).
8.2)
Humidifier:
Terminals are provided to direct 115 volts @ 1.0 Amp maximum to the
transformer powering the humidifier. The humidifier will be energised
anytime the blower is operating on the "Heating Speed". Wire the
115-volts power as indicated in figures # 4.1, # 4.2 and # 4.3.
8.3)
Air conditioning:
An air conditioning coil may be installed on the supply airside only.
Also, notwithstanding the evaporator coil manufacturer's instructions,
a minimum of 6 inches clearance must be allowed between the bottom
of the coil drain pan, and the top of the heat exchanger. Wire the
thermostat and condensing unit contactor as indicated in the wiring
diagram (figures # 4.1, # 4.2 and # 4.3).

Ductwork and Filter:
Installation:
Design and install air distribution system to comply with Air
Conditioning Contractors of America manuals or other approved
methods that conform to local codes and good trade practices.
When furnace supply ducts carry air outside furnace area, seal return
air duct to furnace casing and terminate duct outside furnace space.
Install air conditioning cooling coil (evaporator) on downstream side (in
the supply air plenum) or furnace.
If separate evaporator and blower unit is used, install good sealing
dampers for air flow control. Cold air from the evaporator coil going
through the furnace could cause condensation and shorten furnace
life.
CAUTION
Dampers (purchased locally) MUST be automatic.

Poison carbon monoxide gas hazard.
Do NOT draw return air from inside a closet or
utility room. Return air duct MUST be sealed t o
furnace casing.
Failure to properly seal duct can result in death,
personal injury and/or property damage.
