1 Safety Considerations 2.3 Mounting Options Hazards may exist within this equipment because it contains electrical and powerful moving components. Only qualified service personnel should install or service this equipment. Untrained personnel can perform basic maintenance such as maintaining filters. Observe precautions marked in literature and on labels attached to unit. Follow all safety codes. WARNING Disconnect main power switches to unit before performing service or maintenance.
The supply and exhaust ducts connected to outside, as well as any ducts passing through an unconditioned space, must have a minimum insulation value of R5. In addition, a continuous integral vapor barrier over the duct insulation must be used. Air balancing dampers are recommended for both supply and exhaust ducts to allow for adjustment of airflow.
2.8 Electrical Connections Power A terminal block and strain relief bushing or a junction box is provided for line voltage to make the necessary power connections. The electrical requirements are as follows: VOLTAGE MCA MOP 600 cfm 700 cfm 1200 cfm 115V 8.65 12.5 115V 6.63 9.13 115V 13.4 20 Control Box Access For Low Speed Setting (600 cfm/1200 cfm only) Disconnect power to the unit. Remove the four screws securing the cover plate as shown in Appendix F.
Recirculation Defrost Module (Optional - Factory Installed) The Recirculation Defrost Module is only available with the 600 cfm and 1200 cfm units. The defrost cycle is electronically controlled in response to the outside temperature 23°F to -22°F (-5°C to -30°C). On a call for defrost, the supply air damper in the recirculation module closes, exhaust fan is de-energized and the supply fan continues to recirculate warm air through the heat recovery core.
4.2 Balancing Procedure 1 Before proceeding with balancing, all windows, overhead doors and walk-in doors should be closed and exhaust systems should be turned off. 1 The connections between the flow stations and the ducts must be sealed with tape. Mount the magnehelic gauge in a convenient location where it is level and will not vibrate or be bumped. Zero the gauge. Measure the exhaust air first as it is often the lowest due to a longer duct system. VL0001 600 cfm and 1200 cfm 1.
Allow the heat recovery core to soak for three hours in warm water and mild soap. Rinse under a heavy stream of water. WARNING Hot water and a strong cleaning agent could damage the polypropylene core. Ensure the core is returned to the unit in the correct orientation. Use the sticker as a guide. Fans Blower wheels and fan housing should be checked for dirt build-up. If they appear dirty, it may be necessary to remove the blower assembly and then vacuum the dust out through the fan mouth.
