2.0 TYPICAL INSTALLATIONS There are three (3) common installation methods. 2.1 Fully Ducted System (Primarily for homes with radiant hot water or electric baseboard heating. See figure 1.) Moist, stale air is exhausted from the high humidity areas in the home, such as bathrooms, kitchens and laundry rooms. Fresh air is supplied to bedrooms and principal living areas. The use of bathroom fans and range hood is suggested to exhaust stale air.
3.0 INSTALLATION INSPECT THE CONTENTS OF THE BOX • Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches, door hinges, dampers, duct collars, cabinet, etc. • Inspect the interior of the unit for damage. Ensure that the fan motor assembly, heat recovery core, insulation, dampers, damper actuator, and drain pan are all intact. • If the unit was damaged during shipping, contact your local distributor.
3.0 INSTALLATION (CONT’D) 3.3 Calculating Duct Size Use the table below to ensure that the ducts you intend to install will be carrying air flows at or under the recommended values. Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its air flow exceeds the maximum value.
3.0 INSTALLATION (CONT’D) 3.4 Installing Ductwork and Registers ! WARNING 0 Never install a stale air exhaust register in a room where a combustion device is, such as a gas furnace, a gas water heater or a fireplace. 3.4.1 Fully ducted system (as illustrated in Section 2.1) Stale air exhaust ductwork: • Install registers in areas where contaminants are produced: kitchen, bathrooms, laundry rooms, etc.
3.0 INSTALLATION (CONT’D) Method 2: return side connection • Cut an opening into the furnace return duct at a minimum distance of 10 linear feet upstream where the furnace return duct connects to the furnace cabinet, as measured VD0108 figure 10 minimum along the lenght of the duct. 10’ (3.1 m) upstream • Connect this opening to the fresh air distribution port of the unit (see figure 10).
3.0 INSTALLATION (CONT’D) 3.5 Connecting Duct to the Unit Insulated flexible duct: Use the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to outside and fresh air from outside). a) Pull back the insulation to expose the flexible duct. b) Connect the interior flexible duct to the opening using a duct tie. c) Carefully seal the connection with duct tape. d) Pull the insulation over the joint and tuck it between the inner and outer rings of double collar.
3.0 INSTALLATION (CONT’D) Make sure the intake hood is at least 6 feet (1.8 m) away from any of the following: • dryer exhaust, high efficiency furnace vent, central vacuum vent • gas meter exhaust, gas barbecue-grill • any exhaust from a combustion source • garbage bin and any other source of contamination Refer to figure 14 for connecting the insulated duct to the hoods. Place the “FRESH AIR INTAKE” sticker, provided in the installation kit, on corresponding hood.

5.0 AIR FLOW BALANCING WHAT YOU NEED TO BALANCE THE UNIT • A magnehelic gauge capable of measuring 0 to 0.5 inches in water (0 to 125 Pa) and 2 plastic tubes. • The balancing chart of the unit. PRELIMINARY STAGES TO BALANCING THE UNIT VP0009 • Seal all the unit ductwork with tape. Close all windows and doors. • Turn off all exhaust devices such as range hoods, dryers and bathroom fans. • Make sure the balancing dampers are fully open.
6.0 OVERALL VERIFICATION 6.1 3-Position Switch This procedure allows the installer to verify that all modes of operation are fully functional. During the verification of the 3-position switch, make sure that all optional remote controls are inactive. Set switch to Results expected fan speed / damper LOW HIGH low speed / open high speed / open REMOTE motor off / closed 6.
7.0 MAINTENANCE ! WARNING 0 Risk of electrical shocks. Before performing any maintenance or servicing, always disconnect the unit from its power source. • Review with the user the steps required for regular maintenance of his/her ventilation system. These steps are described in detail in the user manual: FOUR TIMES A YEAR: • • • • Inspect the intake hood, and clean if needed. Clean the filters. Clean the interior of the cabinet, and clean the door.
9.0 TROUBLESHOOTING Note: Be sure to unplug and inspect the unit before proceeding with these steps. Start with point 1,then point 2 and so on. Start-up troubleshooting: Problems Possible causes 1. Unit doesn't work. • Erratic operation of the electronic circuit. • Unplug the unit. Wait for 30 seconds. Plug it back in. • The breaker in the electrical • Reset breaker. If it trips again, unplug the unit and call panel may be tripped. an electrician. • The door switch may be defective.
9.0 TROUBLESHOOTING Problems Possible causes You should try this 5. The defrost cycle • Ice deposits may be hindering • Remove the ice. doesn't work the damper operation. (the fresh air duct is • The damper rod or the port • Inspect these parts and replace if necessary. frozen OR damper itself might be broken. the fresh air distributed • The damper actuator might be defective. • Plug in the unit and select “OFF”. Press the door switch and is very cold.) see if the port damper closes.
