Drain Connection During defrost cycle the HRV unit may produce some condensation and the water should flow into a nearby drain. The HRV cabinet has pre-punched holes(two on side and one on the door) for the drain, in order to keep the drain pan intact, hand tighten the plastic drain spout to the unit using the gasket and nuts. For Vertical installation Cut two sections of ½" drain pipe and connect the other ends to the drain spout then connect to "T" connector. Connect a drain line and create a P-trap to prevent the unit from unpleasant odours from drain source. Tape or fasten base to avoid any bends.

Don't forget to create a P-trap as shown above. Use this drain for horizontal installation ! CAUTION ! The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point or freeze protection must be provided. Air Flow Balancing 5 For units without built-in true Automatic Electronic Air-balancing and for cross verification only Balancing Procedure It is required to have balanced air flows in an HRV/ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit while running at normal speed. If the air flows are not properly balanced, then: · The HRV/ERV may not function at its maximum efficiency · A negative or positive air pressure may occur in the house or condo · The unit may not defrost properly Prior to balancing, ensure that: 1. All the HRV/ERV's components are in place and functioning properly. 2. All sealing of the ductwork system has been completed. 3. Set the unit to normal speed. 4. 5. Air flows in branch to specific areas of the house should be adjusted first prior to balancing the unit. After taking reading of both the stale air to the HRV/ERV duct and fresh air to the house duct, the duct with the lowerCFM reading should be left alone while the duct with the higher airflow should be slower down to 6. match the lower reading by adjusting dial/speed controller on control board(see board layout on page-4). Return unit to appropriate fan speed for normal operation. Pitot Tube Airflow Balancing The following is a method of field balancing an HRV/ERV using a Pitot tube advantageous in situations when flow stations are not installed in the ductwork. Procedure should be performed with the HRV/ERV on normal speed. The first step is to operate all mechanical systems on most desire speed, which have an influence on the ventilation system, i.e.the forced air furnace or air handler if applicable. This will provide the maximum pressure that the HRV/ERV will need to overcome, and allow for a more accurate balancing of the unit. Drill a small hole in the duct (about 3/16"), three feet downstream of any elbows or bends, and one foot upstream of any elbows or bends. These are recommended distances but the actual installation may limit the amount of straight duct. The Pitot tube should be connected to a magnehelic gauge capable of reading from 0 to 0.25 in. (0-62 Pa) or other digital airflow meter. The tube coming out of the top of the pitot is connected to the high pressure side of the gauge/meter and the tube coming out of the side of the pitot is connected to the low pressure or reference side of the gauge/meter. Pitot tube and gauge Duct AIR FLOW High Pressure Pitot tube Tap Magnehelic gauge Low Pressure Tap NOTE: Place the magnehelic gauge on a level surface and adjust it to zero. Insert the pitot tube into the duct; pointing the tip into the airflow. For general balancing it is sufficient to move the pitot tube around in the duct and take an average or typical reading. Repeat this procedure in the other duct. Determine which duct has the highest airflow (highest reading on the gauge). Then slower down that motor speed by adjusting dial/speed controller on control board to match the lower reading from the other duct. The flows should now be balanced. Actual airflow can be determined from the gauge/metre reading. The value read on the gauge is called the velocity pressure and on the flow meter is called air velocity(FPM). The Pitot tube comes with a chart that will give the air flow velocity based on the velocity pressure indicated by the gauge. This velocity will be in either feet per minute or metres per second. To determine the actual airflow, the velocity is multiplied by the cross sectional area of the duct being measured. Air Flow Balancing (cont'd) Note:(Option #2) *For balancing, extension box cover plate is provided with 3 holes on supply side and 3 holes on exhaust side. *Do not use pitot tube to open holes in the insulation as it may block/damage the pitot tube. *Take 3 readings on each hole and average all 9 readings for supply and same for exhaust. *After finish balancing, plug all six holes with plastic plugs provided with the unit.

Note: To take more accurate readings, use option #1(if possible). CFM = Opening / Cross-sectional Area(sq.ft.) x velocity(FPM) The accuracy of the flow reading will be affected by how close to any elbows or bends the readings are taken. Accuracy can be increased by taking an average of multiple readings as outlined in the literature with the Pitot tube. Maintenance Regular Maintenance 1. Turn the unit off and disconnect the power supply. 2. Unlatch the door and lift the door panel towards you, hold it firmly and slide it to the left. 3. Clean the inside of the door and drain pan with a damp cloth to remove dirt and debris that may be present. 4. Clean the filters: (twice a year) - Remove the filters. - Vacuum to remove most of the dust. - Wash with a mixture of warm water and mild soap. Rinse thoroughly and shake filters to remove water and let dry. 5. Oil/grease defrost damper levers and hinges. 6. Check the exterior fresh air supply hood: - Make sure there are no leaves, twigs, grass, ice or snow that could be drawn into the vent. Partial blocking of this air vent could cause the unit to malfunction. 7. Reassemble the components, Filters and Door (The door is secured when you hear a click.) 8. Reconnect the power and turn on the unit. Maintenance (cont'd) 7 Annual Maintenance Repeat steps 1 to 5 from the previous section and continue with the following steps: 1. Clean the HRV and ERV core: - Remove filters, Loosen the core locking bracket, Remove the core, carefully grip ends of core and pull evenly outward - HRV Core > remove dust using vacuum cleaner or rinse with cold water > Soak and rinse the HRV core in warm soapy water - ERV Core > remove dust using vacuum cleaner 2. Motors - Maintenance Free, permanently lubricated ! ATTENTION ! · Do not use cleaning solution for the HRV/ERV core · Do not use pressure washer on the HRV/ERV core · Do not place the HRV/ERV core in dishwasher · Do not use bleachor chlorine 3. Drain Tube and Drain Pipe - Inspect drain tube, drain pipe and "P" trap for blockage, mold or kinks. Flush with warm soapy water and replace if worn, bent or unable to clean. 4. Clean Duct Work if Required - Wipe and vacuum the duct once every year. The duct work running to and from HRV/ERVmay accumulate dirt. You may wish to contact a heating / ventilation company to do this. 5. Cleaning the Fans - Fans may accumulate dirt causing an imbalance and/or excessive vibration on the HRV/ERV. A reduction in the air flow may also occur. In new construction this may result within the first year due to heavy dust and may occur periodically after that over time depending on the outdoor conditions. · open the servicedoor · remove the core ! WARNING ! · disconnect the fan motor wires · remove the screws securing fan assembly · pull the fan assembly out of unit · check for any accumulation on the blades Electrical shock hazard.
