Lifebreath 94-EXCHANGER, 99-MD-KIT Maintenance, Inspect Exterior Hoods at least once a month

Maintenance HRV

1. Inspect Exterior Hoods at least once a month.

Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In winter, it is especially important to make sure snow is not blocking the hoods or that frost has not built up on the wire mesh (bird screen).

WARNING: Blockage of hoods may cause an imbalance.

2. Clean Air Filters - Twice a Year

The standard filters equipped with your HRV are remov- able and washable.

a)simply open access door and slide core out

b)remove filter clips

c)once clips are removed filters can be taken off the core to be rinsed with water or a combination of mild soap and water. Do not clean in the dishwasher

d)to re-assemble, place clean filter(s) (wet or dry) back into their positions against the core and return clips to their original position

e)slide core back into its original position

3.Clean Core - Twice a Year

a)open access door

b)carefully grip ends of core and pull evenly outward. -core may be snug, but will slide out of the channel

c)once removed from the cabinet remove filters

d)wash core in warm soapy water (do not use dishwasher)

e)install the clean filters

f)install clean core

Note: Core installation label on the outer end of the core.

To install the clean core:

a)first mount the bottom flange of the core guide into the bottom H channel approximately 1/4” (6mm)

b)mount the left or right side flange of the core guide approximately 1/4” (6mm) followed by the other side

c)mount the top flange of the core guide into the top H channel approximately 1/4” (6mm)

d)with all four corners in place and the core straight and even, push hard in the center of the core until the core stops on the back of the cabinet

NOTE: Core will appear to stick out from cabinet approxi- mately 1/8” (3mm). This is designed this way so that the access door will fit tight against the core.

4. Drain (condensate) Line - Clean Once a Year

Inspect drain line, drain spout and “P” trap for blockage, mold or kinks. Flush with warm soapy water and replace if worn, bent or unable to clean.

5. Clean Duct System if Required

The duct system running to and from the HRV may accu- mulate dirt. Wipe and vacuum the duct once every year. You may wish to contact a Heating/Ventilation company to do this.

6. General Maintenance - Twice a Year

Wipe down the inside of the cabinet with a damp cloth to remove dirt, bugs and debris that may be present.
