Anleitung Zusammenfassung


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 ALTERNATE FURNACE INTERLOCK WIRING.

Before performing any maintenance or servicing, always disconnect the unit from its power source. 7. BALANCING THE UNIT To avoid balancing, the difference between stale air ducts total lenght and fresh air ducts total lenght must not exceed 50 ft. However, even if the stale air ducts and fresh air ducts lenghts are almost equal, your local building codes may require balancing the unit. If the unit does not need to be balanced, shut all the pressure taps (located on the unit door) with the small plastic plugs included in the hardware kit. 7.1 WHAT YOU NEED TO BALANCE THE UNIT • A magnehelic gauge capable of measuring 0 to 0.5 inch of water (0 to 125 Pa) and 2 plastic tubes. • The balancing chart located on the unit door. 7.2 PRELIMINARY STAGES TO BALANCE THE UNIT VP0009 • Seal all the unit ductwork with tape. Close all windows and doors. • Turn off all exhaust devices such as range hood, dryer and bathroom fans. • Make sure the integrated balancing dampers are fully open. Turn the thumb screw (A ) clockwise to manually open the dampers. Both are located on the Exhaust air to outside port and on Fresh air to building port. • Make sure all filters are clean (if it is not the first time you balance the unit). VJ0032 A Port with integrated balancing damper - Top view 7.3 BALANCING PROCEDURE 1. Set the unit to high speed. Make sure that the furnace/air handler blower is ON if the installation is in any way connected to the ductwork of the cold air return. If not, leave furnace/air handler blower OFF. If the outside temperature is below 0°C / 32°F, make sure the unit is not running in defrost while balancing. (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 ...
