4. Typical Installations There are three (2) common installation methods. 4.1 FULLY DUCTED SYSTEM (Primarily for homes with radiant hot water or electric baseboard heating. See Figure 1.) The complete ductwork of the ventilation system consists in ducts for the fresh air distribution and other ducts dedicated to exhaust moist, stale air to the outside. Fresh air is supplied to bedrooms and principal living areas (at least one register per level).
5. Installation INSPECTING THE BOX CONTENT • • • • 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 condensation tray are all intact. If the unit was damaged during shipping, contact your local distributor.
5. 5.3 Installation (cont’d) CALCULATING THE DUCT SIZE Use the table below to ensure that the ducts you intend to install will be carrying air flows at/or under the maximum air flow values. Never install a duct if its air flow exceeds the maximum value. NOVOCLIMAT CHART FOR SIZE OF DUCT CONNECTED TO REGISTER VS.
5 5.4 Installation (cont’d) INSTALLING THE DUCTWORK 0 ! AND REGISTERS WARNING Never install a stale air exhaust register in a room where there is a combustion device, such as a gas furnace, a gas water heater or a fireplace. 5.4.1 Fully Ducted System (as illustrated in Section 4.1) Stale air exhaust ductwork: • • • • Install registers in areas where contaminants are produced: bathrooms, laundry room, etc.
5. 5.5 Installation (cont’d) CONNECTING THE DUCTS 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 port using a duct tie. c) Carefully seal the connection with duct tape.
5. 5.6 Installation (cont’d) INSTALLING THE EXTERIOR HOODS Choose an appropriate location for installing the exterior hoods: • a minimum distance of 6 feet (1.8 m) between the hoods to avoid cross-contamination • a minimum distance of 18 inches (457 mm) from the ground Make sure the intake hood is at least 6 feet (1.
5. Installation 5.7 CONNECTING THE DRAIN (cont’d) Inside view 1 VO0010 VO0008 2 In order to keep the drain pan intact, hand tighten the 2 plastic drain fittings to the unit using the gaskets, washers and nuts as shown. To install the drain fittings, punch the 2 knock-out sections located at the bottom of the unit. 12" (305 mm) 3 VO0004A VO0005 Join the 2 short sections to the “T” junction and main tube as shown.

INSTRUCTIONS: 1- Determine the location of the control. The wall control must be installed in a central location on the main floor. Typical locations for these controls are main hallways and family room.
6. Maximum Main Control 6.2 MAIN CONTROL INSTALLATION (cont’d) (CONT’D) 5- Make sure the instruction pull-out is in the occupant’s language. If not, turn it to the other side. 6- Reinstall the cover plate and the button. VC0061 7- Connect the wires to their corresponding position inside the electrical compartment. Make sure the connections of the unit and of the wall control correspond exactly. 8- Connect the optional controls.
VE0017A NOTES ELECTRONIC ASSEMBLY T1 W BK GY ABCDEFG BK O R 6- The furnace fan circuit must be class 2 circuit only. 5- The field wiring must comply with applicable codes, ordinnances and regulations. 4- Use the factory supplied protective tubing. 3- If any of the original wire, as supplied, must be replaced, use the same or equivalent wire. 2- The factory set wiring for blower speed selection is high and low. Medium speed can be selected instead of low speed.
8. Air Flow Balancing 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 provided with the unit. VP0009 PRELIMINARY STAGES TO BALANCE THE UNIT • • • • 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 balancing dampers are fully open.

11. Troubleshooting NOTE: Be sure to unplug and inspect the unit before proceeding with these steps. Start-up troubleshooting: Problems Possible causes You should try this 1. Unit doesn't work. • The circuit board may be defective. • Unplug the unit. Disconnect the main control and the optional(s) control(s). Jump B and G (BLACK and GREEN) terminals. Plug the unit. If the motor runs on high speed and the damper opens, the circuit board is not defective. B G VE0082 2.
11. Troubleshooting (cont’d) Problems Possible causes You should try this 5. The defrost cycle does not work (the fresh air duct is frozen OR the fresh air distributed is very cold OR the “AIR EXCHANGE” light flashes). • Ice deposits may be hindering the damper operation. • Remove the ice. • The damper rod or the port damper itself may be broken. • Inspect these parts and replace if necessary. • The damper actuator may be defective. • Plug in the unit and select “MIN.” or “MAX.
