IMPORTANT: Due to the hygroscopic nature of the
POE oil in Puron refrigerant (R-410A) and other envi-
ronmentally balanced refrigerants, any component
replacement must be conducted in a timely manner
using caution and proper service procedure for these
types of refrigerants. A complete installation instruction
will be included with each replacement TXV/filter drier
assembly. It is of critical importance these instructions
are thoroughly understood and carefully followed. Fail-
ure to follow these instructions can result in a system
that is contaminated with moisture to the extent that sev-
eral filter drier replacements may be required to properly
dry the system.
IMPORTANT: Repair of any sealed refrigerant system
requires training in the use of refrigeration tools and proce-
dures. Repair should only be attempted by a qualified ser-
vice technician. A universal refrigerant handling certificate
will be required. Local and/or state license or certificate
may also be required.
CAUTION
Disconnect power from unit before removing or replacing
connectors, or servicing motor. Wait 5 minutes after dis-
connecting power before opening motor.
