Page 4: About The H/Erv
1 ABOUT THE H/ERV The heat recovery ventilator (HRV) provides fresh air to a conditioned space while exhausting an equal amount of stale air. Heat energy is transferred from one air stream to the other within a non-contact cross flow heat exchanger. ERV models transfer latent energy (moisture) from the higher to lower air stream. -

4 SAMPLE SPECIFICATION GENERAL System description: Packaged Heat (Energy) Recovery Ventilator capable of transferring sensible (sensible and latent) energy designed to be used as a standalone ventilation system or as part of an engineered HVAC system with flat plate, cross flow heat exchanger integral to the unit. - Page 9 Blowers Blowers shall be FC DWDI, dynamically balanced and operate at not more than 1500 rpm. Internal vibration isolation is not required. Blower housing shall be galvanized steel. Motors Motors shall be continuous duty, permanently lubricated with a service factor of 1.15, matched to the fan load and required voltage and phase.
- Page 10 Both defrost and run cycles shall be field adjustable via the unit’s control. Recirculation Defrost (NU0820) – a temperature sensor initiates defrost when outside air is cold enough to freeze condensate. The exhaust fan shuts down, the recirculation damper opens, the gravity and motorized back draft dampers close.

Page 40: Installation
10 INSTALLATION The HRV motors are controlled and protected by a multi-starter which includes a disconnect switch. A Hand/Off/Auto selector is located on the starter for local or remote switching. 10.1 Remote Control Any dry contact switch closure may be used. Control voltage is 24 VAC. 10.1.1 INSTALLATION INSTRUCTIONS 10.1.1.1 Installer's Responsibilities... - Page 41 5. Apply the foam gasket to all top flanges of the curb forming a continuous, watertight seal. 6. With the HRV lifted, connect the drain hose to the spouts from underneath, feed the fresh air hose through the center curb member and tee into the exhaust drain.
-
Page 42: Connecting To Other Equipment
10.4 Connecting To Other Equipment If the HRV is used upstream of an air handler or similar equipment (e.g. fresh air into economizer section), the startup sequence must be HRV first followed by the air handler. If the air handler is started first, the HRV's fresh air fan will rotate backward and the motor may not be able to overcome the extra load causing the motor to over amp and potentially damage the blower wheel. -
Page 43: Balancing The System
10.6 Balancing The System Unless otherwise specified by the system designer, set up the HRV with balanced supply and exhaust air flows. The pulleys used on the supply and exhaust motors are a split type that allows some field adjustment of the fan rpm and corresponding air flow. Adjust the pulley in ½... -
Page 44: Commissioning And Start Up - Compliant Series
10.7 COMMISSIONING AND START UP - COMPLIANT SERIES Conduct a visual comparison of the HRV against the “As Built Drawing” available from the factory. Correct air flow configuration Correct Motors Installed Correct Pulleys Installed Correct Defrost Installed Correct Belts Installed also check tension, alignment and wear. - Page 45 At this point the unit is ready for final air balancing. The fan rpm and cfm have been factory set to as near as practical to the specified level. A certified air balancer will fine tune the air flows using dampers and adjusting the motor’s pulleys if needed.
