Visual observation of the ERV interior -

Check the following:

❑

Check that the wheel can move freely. Spin by hand to

insure that nothing is impeding the wheel’s movement.

❑ Check that the wheel is receiving power. With the

door open, push in on the safety switch and insure

that the wheel rotates. The wheels rotate between 40

and 60 rpm.

❑ Check the wheel for dirt. If the wheel or segments

of the wheel are dirty, Clean them using a non-acid

based coil cleaner or alkaline detergent solution.

❑ Check the ﬁ lters. If dirty, replace.

❑

Check the blowers. Insure that the blowers are rotating

in the right direction. Check that the seals around the

doors are not cut, damaged or have holes in them that

would allow water to penetrate into the cabinet.

❑ Check belts for wear and tension. Belts can be

compressed about one-half inch.

❑ Check alignment of the pulleys.

❑ Check that the bushings in the blowers are in place.

❑ Check that the cabinet interior is dry.
