ERV UNIT COUPLED WITH A 3 to 121/2 TON HVAC UNIT — Complete the following steps to install a transition to a3to 121/2 ton rooftop unit. 1. Remove the HVAC unit filter door and set aside for later use. 2. Remove the panel shipped on the HVAC unit covering the return air chamber. This panel can be discarded. 3. The 62M ERV transition for 3 to 121/2 ton rooftop units includes a replacement panel to cover the return opening. Install the replacement panel, with hood scoop attached, onto the HVAC unit, over the return air chamber. Screw in place. The return/exhaust scoop will cover part of the return air opening in the HVAC unit. NOTE: The standard transition does not seal tight around the return air opening on the HVAC unit. This allows for some air to flow back to the HVAC unit and some to be drawn back through the ERV unit. 4. Slide the transition between the ERV unit and the HVAC unit. Refer to Fig. 17-44 to orient the transition. Line up the transition so that it covers the openings in the HVAC unit and the ERV unit. The divider in the transition must separate the supply and return openings in the ERV unit. Screw the mating flanges of the transition to the ERV unit through pre-punched holes. Caulk the seams watertight. Screw the mating flanges on the other side of the transition to the new return air cover panel on the HVAC unit. Caulk seams watertight. 5. On most models the filter access door shipped with the HVAC unit will be reinstalled above the transition. 6. The transition includes a balancing damper to allow for the desired separation of the return/exhaust air between the ERV and HVAC units. This damper has a manual adjustment. During balancing, this damper will be adjusted to achieve desired exhaust cfm. The balancing damper can be accessed through a separate door in the transition or through the HVAC unit’s filter access door. See Fig. 17-44. Step 5 — Make Electrical Connections Prior to performing service or maintenance operations on the ERV unit, turn off and disconnect all power switches to the unit. Be aware that there may be more than one disconnect switch. Electrical shock could cause serious personal injury or death. IMPORTANT: Only trained, qualified installers and service technicians should install, wire, start-up and service equipment. POWER SUPPLY — The electrical characteristics of the available power supply must agree with the unit nameplate rating. Supply voltage must b...
