/ HRV

INTRODUCTION

The Energy/Heat Recovery Ventilator (ERV/HRV) is used to exchange indoor stale air with outside fresh air. The unit is equipped with a special energy/heat recovery core which transfers both sensible and/or latent heat between the fresh incoming air and stale exhaust air. The cross-flow design core allows entering and leaving air streams to transfer heat and/or latent energy without mixing (See Fig. 3).

ERV/HRV is installed in conjunction with a forced-air system, unit should be located next to (or close to) the indoor equipment.

COMPONENT DESCRIPTION

The following listed items are components of ERVCCSHA (See Fig. 4).

1.Exhaust-air connected to outdoor air exhaust hood.

2.Fresh-air intake connected to outdoor air inlet hood.

3.Fresh-air supply from ERV connected to return-air duct of forced-air system.

4.Mechanical filters trap dust contained in the air.

5.Energy recovery core is a cross-flow type. The core trans- fers heat between the 2 air streams.

6.Blowers bring in fresh-air from outside and exhaust stale- air to outside.

7.Electronic control circuit ensures proper unit operation.

8.Stale air return from building connected to return-air duct system.

(Bottom view with access door removed)

The model operates at 2 airflows, 50 CFM in low speed and 100 CFM in high speed. This unit comes in two configurations, vertical or horizontal. Special attention should be given to duct application, balancing the ERV/HRV, and locating unit for easy access and routine maintenance.

INSTALLATION CONSIDERATIONS

Inspect Equipment

Move carton to final installation location. Remove ERV/HRV from carton taking care not to damage unit. Remove all packaging and inspect unit for damage. Remove parts bag from inside unit. File claim with shipping company if shipment is damaged or incomplete. Check to make sure ERV/HRV unit matches Fig. 1 or Fig. 2.

Select Location

The ERV/HRV should be located in a conditioned space and in close proximity to a fused power source. It should be easily accessible for routine maintenance.

If ERV/HRV is installed independent of a forced-air system, unit should be located near the center of the air distribution system. If
