Maintenance
and
Replacement
DANGER
The refrigeration circuits are high pressure systems.
Hazards exist that could result in personal injury or death. It
is therefore required that the removal and installation of this
scroll compressor be performed by a technician qualified in
R-410A refrigerant. See Hazard Levels, page 3.
DANGER
Never use oxygen to pressurize a refrigeration system. Oxygen can explode on contact
with oil and could result in personal injury or death. When using high pressure gas
such as nitrogen for this purpose, ALWAYS USE A PRESSURE REGULATOR that
can control the pressure down to 1 or 2 psig. Failure to use a regulator will result in
extremely high pressure which could exceed the burst pressure of the compressor
or other system components and result in personal injury or death. See Hazard
Levels, page 3.
1) Verify that the electrical power has been turned off and the disconnect
switch locked.
2) Use a soft brush to remove any dirt and debris from the coil.
3) Spray with cold or warm (not hot) water and a cleaning solution (non-acid
based coil cleaner is recommended). Due to possible damage to the coil,
do not use high pressure spray.
4) When clean, rinse with cool, clean water.
If additional cleaning is required or if the coil must be removed for any reason,
consult the factory. Be prepared to provide rating plate and installation informa-
tion.
