Air Coil
To obtain maximum performance, the air coil should be
cleaned before start-up. A 10% solution of dishwasher
detergent and water is recommended for both sides
of the coil. A thorough water rinse should follow. UV
based anti-bacterial systems may damage e-coated
air coils.
NOTICE! Failure to remove shipping brackets
from spring-mounted compressors will cause
excessive noise, and could cause component
failure due to added vibration.
