conduit.
10. Installer le filtre à air de l’appareil en place.
11. Installation du panneau avant.
12. Nettoyer l’appareil/boîtier-manchon pour enlever la poussière, etc.

Cet appareil est maintenant prêt à fonctionner quand il sera alimenté à partir du panneau électrique et relié au
thermostat.
NOTA :
Quand vous manipulez le châssis, vous devez prendre soin de ne pas endommager les roulettes du ventilateur.
Des ventilateurs endommagés ou déséquilibrés produiront un bruit anormal et nuiront au bon fonctionnement de
l’appareil.

The Unitary Package Heating, Cooling Unit has been carefully designed and built to provide reliable operating
performance when installed and maintained correctly.
CONTROL SYSTEM DESCRIPTION
The unit is controlled on both heating and cooling by a low voltage wall mounted thermostat.
Any standard 24-volt heat/cool thermostat intended to control a gas-heating unit with cooling can be made to work
with the unit as long as there are enough heating stages; this includes auto changeover and electronic
thermostats. Units 4 KW and under have 1 stage of heat, and units with 4.5 KW of heat and greater have 2 stages
of heat. Therefore, the thermostat should be chosen accordingly. A room thermostat is basically a switch used to
direct 24 volt power from the “R” terminal to its W, (or W1, W2), Y, and G terminals, according to the function
being demanded by the user. Sometimes an electronic thermostat needs to be powered with 24 volts via
connection to an additional “C” or “Common” terminal, typically if its display is backlit. If the thermostat demands
that the “C” connection be made at the thermostat wiring terminals, then please order the additional black lead
that will insert into the unit’s low voltage connector, Part No. 18BK23Y-024.
Heating and cooling will be cycled on, as dictated by the setting of the wall thermostat. In this mode, the room-
side fan will run at factory-predetermined speeds for heating and cooling. The fan will be off when neither heating
nor cooling are required.
