(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 more restriction than the fresh air, especially in cases of fully ducted installations or source point ventilation. Place the magnehelic gauge upright and level. Record equivalent AIR FLOW of the reading according to the balancing chart. 4. Move tubing to FRESH air flow pressure taps (see diagram). Adjust the fresh air balancing damper until the fresh air flow is approximately the same as the EXHAUST air flow. If fresh air flow is less than exhaust air flow, then go back and adjust the exhaust balancing damper to equal the fresh air flow. 5. Secure both dampers thumb screw in place with tape. 6. Write the required air flow information on a label and stick it near the unit for future reference (date, maximum speed air flows, your name, phone number and business address). NOTE: The unit is considered balanced even if there is a difference of ±10 cfm (or ± 5 l/s or 17 m3/h) between the two air flows.

CONNECTING THE DRAIN (HRV UNITS ONLY) VD0181 A From the inner side of the unit door, using the provided drain tube, punch out both drain holes (A). VO0092 Cut 2 sections of plastic tubing, about 12” (305 mm) long and attach them to each drain fitting. Join the 2 short sections to the “T” junction and main tube as shown. VO0091 In order to keep the drain pan intact, hand tighten the 2 plastic drain fittings to the unit door using the gaskets and nuts as shown. VO0093 To drain Tie-wrap Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the drain source. Make sure this loop is situated BELOW the “T” as shown. This will prevent water from being drawn back up into the unit in case of negative pressure. Run the tube to the floor drain or to an alternative drain pipe or pail. Be sure there is a slight slope for the run-off. - 22 9. MAINTENANCE WARNING Risk of electrical shocks. Before performing any maintenance or servicing, always disconnect the unit from its power source. ! Since this guide covers both HRV and ERV units, top and side ports, the illustrations shown in the maintenance procedures are typical. The following procedures applies for both HRV and ERV units. Refer to pictures below to identify the inner parts of your unit. 1 3 3 4 2 2 1 3 3 4 VB0078 VB0077 2 2 1) HRV core 3) Foam filter brackets 1) ERV core 3) Foam filter brackets 2) Core retainers 4) Foam core filters 2) Core retainers 4) Foam core filters 9.1 SEMI-ANNUAL MAINTENANCE 1. Unplug the unit. VD0005 WARNING ! Be careful before opening the door; water or small debris could fall out. For HRV unit, always wait one minute after disconnecting the unit before opening the door in order to allow water to drain out from the unit. 2. Unlatch the door and open it. Clean the inner side of the door with a damp cloth, then wipe with a dry one. Disengage the door from its hinge by sliding it from left to right and set aside. VD0179 WARNING ! Always hold the core when rotating the 2 core retainers; failure to do so will cause the core to fall out. 3. Lift both foam filters bracket (1) and remove the foam filters from the core. While holding the core, rotate the 2 core retainers (2) and slide out the core from the unit. 1 1 2 VD0177 - 23 9. MAINTENANCE (CONT’D) 9.1 SEMI-ANNUAL MAINTENANCE (CONT’D) 4. Clean the inside walls of the unit with a clean damp cloth, then wipe with a clean dry one. 5. Wash the 2 core filters under hot water with mild soap. Rinse thoroughly and let dry completely before reinstalling on the core. 6. Remove the dust on the core using a vacuum cleaner and a soft brush attachment. WARNING ! Once the core reinstalled in the unit, always rotate both core retainers to their initial position; failure to do so will cause the core to fall out. 7. Slide the core in the unit. Secure the core by rotating both core retainers to their initial positions. NOTE: Once the core reinstalled in the unit, the arrows (A) on its sticker label must be pointing towards the unit motors. VD0178 VB0078 A 8. Reinstall both foam filters and secure them to the core by pulling down the 2 foam filter brackets. Reinstall the door. 9. Close the door and plug the unit. NOTE: The unit will return to its previous setting after a 30-second delay for boot sequence. 9.2 ANNUAL MAINTENANCE Do the same operations as the Semi-Annual Maintenance (Section 9.1).Then, clean the exterior hood(s). - 24 - 25 - VL0019 10.
