REQUIREMENTS

MAINTENANCE

DO NOT WASH THE ENERGY 

EXCHANGE CORE.

Keep it away from water or fire to 
avoid damaging it. Always handle 
the core carefully.

Filters must be used or the energy 
exchange core will become 
blocked by dust and reduce 
unit efficacy.  In extreme cases 
components may be damaged.

CAUTION

TO CLEAN THE ENERGY EXCHANGE ELEMENT

Vacuum the face of the energy exchange element yearly. Dust collects only on the entering face of the energy 
exchange element, right where the filter sits. The interior of the energy exchange element stays clean even 
if the element faces are dust covered. The RenewAire core airflow paths are designed to transport the air 
in a laminar motion. The core flutes move the air in a laminar airflow such that particulate deposition is 
maintained at virtually nill.

1.

 Remove the filters.

2.

 Vacuum the exposed faces of the energy exchange core with a soft brush.

3.

 Vacuum out dust from the rest of the unit case.

4.

 Install new filters.

INSPECT AND CHANGE THE FILTERS REGULARLY

Inspect and/or replace filters every two or three months when the unit is in regular use, or as needed.

1.

  Turn off unit completely! Lock-out and tag-out the unit disconnect switch.

2.

  Open the Door. The door is secured with turn-type latches or draw latches, plus one Phillips-head 

securing screw. Keep the securing screw. 

NOTE:

 Always replace securing screw when reinstalling door 

for safety reasons.

3.

  Remove and dispose of all (4) filters. Replace all (4) filters. 

NOTE: 

See chart for information on the 

initial resistance of the filters originally supplied with this unit. If replacement filters have higher 
resistance, the airflow of the system will be lower.

4.

  Close door; reinstall securing screw.

BLOWER INSPECTION

Inspect Blowers every time you change the filters.

1.

  Confirm bearings are still secure to blower shaft. It should not be possible to move the blower shaft 

back and forth along its length.

2.

  Confirm blower wheel is not rubbing against the blower inlet or housing by rotating wheel manually.

BLOWER BELT TENSION

Check belt tension every time you change the filters.

1.

  Inspect belt(s) for cracking or uneven wear.

2.

  Check that sheaves are properly aligned so that belt runs straight.

Properly tensioned belt will deflect 0.25" when pressed at the center point with the following force:  
1.5 and 2 HP BLOWER - 3 pounds

GENERAL CLEANING AND INSPECTION

Perform general cleaning and visual inspection when changing filters.

1.

  Remove dust from blower wheels periodically.

2.

  Remove paper, leaves, etc. from inlet and outlet screens.

3.

  Inspect for insect nests.

MOTOR MAINTENANCE

If the motors used in this ERV are equipped with grease fittings, motors must be lubricated as part of 
routine maintenance. Use Exxon Polyrex or equivalent at 2500 operating hour intervals. 

Incorrect Belt Tension will damage 
this blower and bearings.

CAUTION

Danger of injury from un-guarded drive belts in unit. Disconnect power to unit before opening door.
Danger of injury if unit starts unexpectedly. Switch power off at service disconnect.  
Lock-out/tag-out the disconnect.
