2.4 Ductwork 2. Installation The supply and exhaust duct connections on the unit are as follows: 2.1 Inspection UNIT Inspect the exterior of the unit for shipping damage by ensuring that there is no damage to the door, door latches, door hinges, damper, duct collars, cabinet, etc. Inspect the interior of the unit for damage by ensuring that the fan motors and housings, heat exchange core, insulation, dampers, actuators and drain pans are all intact.
2. Installation (cont’d) 3. Controls 2.6 Exterior Hoods 3.1 General Information It is important that the fresh air intake hood be positioned well away from any source of contamination. The exterior supply and exhaust hoods must be separated enough to prevent cross-contamination and at an elevation that will prevent blockage by snow, dirt and leaves. FAN INTERLOCK RELAY OUTPUT (FF) NOTE: SPEED SELECTION (6LC /12LC UNITS ONLY) Consult local building code for restrictions in your area.
3. Controls (cont’d) 5. Maintenance and Service 3.3 Defrost 5.1 Bi-Monthly Maintenance The unit functions are controlled by integrated controls in the unit which may include Exhaust Only Defrost or Recirculation Defrost (via the recirculation module - B6LC and B12LC units only). In cold temperatures, defrost cycles will remove frost from the heat exchanger to maintain good operation.
MOTOR AND BLOWER REMOVAL AND INSTALLATION 5. Maintenance and Service (cont’d) Disconnect power from the unit. To determine if the fan motor is burned out, disconnect the four-wire service connector between the motor and cabinet. Connect the motor directly to a 115 volts power source with an electrical cable, as follows: 5.2 Annual Maintenance ! WARNING Disconnect power before maintaining unit.

Appendix E TERMINAL CONTROL DIAGRAMS E-1: TERMINAL LABEL E-2: WALL CONTROL CONNECTION A low voltage remote control wiring interface is provided on the unit. The connections for the low voltage remote wiring are located on two terminals adjacent to the exhaust fan outlet (or adjacent to the supply fan outlet on the B1600705 unit). All field installed wiring must be low voltage class II. Two types of remote wall controls are available: 1.
Appendix E (cont’d) TERMINAL CONTROL DIAGRAMS E-4: REMOTE FAN CONTROL E-3: OCCUPIED TIMER/SENSOR CONNECTION (NOT SOLD BY BROAN) Remote fan control can be achieved by connecting dry contact controls to the terminal interface at terminals labeled: LOW - COM - HIGH. Occupancy control is achieved by connection to the terminal interface shown below.
