27 Maintenance Routine for ERV Maintenance Routine for ERV (for HRV, see previous page) 1. Inspect Exterior Hoods at least once a month 5. Clean Duct Work if Required Make sure exhaust and fresh air supply hoods are not blocked up or restricted by leaves, grass, or dirt. WARNING: Blockage of hoods may cause an imbalance. 2. Clean Air Filters Four Times a Year The standard filters equipped with your ERV are removable and washable. a) simply open access door and slide core out b) remove filter cli

a forced air furnace or air handler, operating at a higher static. After installation, the compatibility of the two pieces of equipment must be confirmed by measuring the airflow’s of the Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) by using the balancing procedure found in this manual. It is always important to assess how the operation of any HRV/ERV may interact with vented combustion equipment (ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.). NEVER install a ventilato

A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the HRV/ERV port and the weatherhood prior to clamping. To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV/ERV should be stretched tightly and be as short as possible. Twisting or folding the duct will severely restrict air flow. See below for the recommended connection of flexible insulated ducts to the the outside weathe

Condensation or Ice Build Up in Insulated Duct to the Outside • incomplete vapour barrier around insulated duct • a hole or tear in outer duct covering • tape and seal all joints • tape any holes or tears made in the outer duct covering • ensure that the vapour barrier is completely sealed Water in the bottom of the HRV • drain pans plugged • improper connection of HRVs drain lines • HRV is not level • ensure O-Ring on drain nozzle sits properly • look for kinks in line • check water drain conne

The straps are designed to reduce the possibility of noise, resonance or harmonics; therefore using the full length of the strap between the HRV/ERV and the floor joists is recommended. Electrical The HRV/ERV should be plugged into a standard designated (120VAC) electrical outlet with ground. It is not recommended that an extension cord be used for this appliance. If further wiring is required, then a licensed electrician should make all electrical connections. It is recommended that a separate

We recommend aluminum foil tape. Stale Air Return System The stale air return system is used to draw air from the points in the building where the worst air quality problems occur. Balancing dampers and/or adjustable grilles are recommended on all return air lines which are used during installation to help balance the “draw” from different areas of the building. Alternately, the stale air may be drawn directly from the return air duct. When this system is used, the air handler’s blower must cons

(Fig. 3) MOUNTING 1. Locate mounting bolts (4) on side of TFP cabinet for vertical hanging (Fig. 3) and remove. 2. Measure distance between the bolts and mark it on the floor/header joist where the TFP is to be hung. 3. Fasten hanging straps to floor joists using wide head nails or screws with washers. 4. Insert hanging bolts through prepunched holes in straps and lift TFP into position. Tighten and secure bolts. DUCTING 1. Install (2) 7” port collars (provided) on TFP cabinet with (8) 8/32” X 3
