BEFORE PERFORMING MAINTENANCE ON THE UNIT, READ AND UNDERSTAND
THE SAFETY INFORMATION CONTAINED WITHIN THE SAFETY CHAPTER OF THE
HEPAIR MANUAL.
DANGER

SHARP EDGES
RISK OF SEROUS INJURY
Sharp edges are present on the fan wheels, housing, fins and coils.
Maintenance on HEPAir units requires working with high voltage and sheet metal with
possible sharp edges. Only qualified personnel should perform maintenance. Some tasks
require knowledge of mechanical and electrical methods. Make sure you are familiar with all
hazards, general safety related procedures, and safety labels on the unit.
CAUTION
EXPOSURE TO MICROBIAL GROWTH (MOLD) CAN CAUSE SERIOUS HEALTH PROBLEMS
Standing water in drain pans promote microbial growth (mold) that cause unpleasant odors
and serious health-related indoor air quality problems. If mold is found, remove it
immediately and sanitize that portion of the unit
.
The HEPAir is designed for minimal maintenance. The refrigerant system is hermetically
sealed and requires no maintenance. The fans are permanently lubricated and require no
maintenance. Some maintenance to the unit may be required due to dust or dirt in the air stream.
Cleaning the Filters
The condenser coil is provided with a reusable, washable air filter. The filter protects the coil
from becoming coated or plugged by dust. Frequency of cleaning the filters is based on the
amount of dust or dirt generated in the space to be conditioned.

2.
Remove the filter covering the face the coil.
3.
