NOTE: Home with multiple forced air systems should have one unit on each system. Stale air coming from the registers located at the highest level of the house is exhausted to the outside. Fresh air from outside is filtered and supplied by the register located in the lowest liveable level. Homes with more than one level require at least one exhaust register at the highest level. See figure at right. Stale air coming from the registers located at the highest level of the house is exhausted to the

(By waiting 10 minutes after plugging the unit in, you are assured that the unit is not in a defrost cycle.). 2. Place the magnehelic gauge on a level surface and adjust it to zero. 3. Connect tubing from gauge to EXHAUST air flow pressure taps (see diagram beside). Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops below zero, reverse the tubing connections. NOTE: It is suggested to start with the exhaust air flow reading because the exhaust has typically mo

ELECTRICAL CONNECTION TO THE FURNACE WARNING Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low voltage class 2 circuit of the furnace blower control. 0 ! For a furnace connected to a cooling system: On some older thermostats, energizing the «R» and «G» terminals at the furnace has the effect of energizing «Y» at the thermostat and thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERN
