Removal Procedure 315
1.7 Removal of the Distributor
Procedure Warning Be sure to wait 10 minutes or more after turning off all power supplies
before disassembling work.
Step
Procedure Points
1
Remove the putty.
Warning
Ventilate when refrigerant
leaks during the work.
(If refrigerant contacts fire, it
will cause to arise toxic gas.)
Caution
Be careful not to get yourself
burnt with the pipes and other
parts that are heated by the
gas welding rod.
Caution
From the viewpoint of global
environment protection, do
not discharge the refrigerant
gas in the atmosphere. Make
sure to recover the refrigerant
gas with the recovery system.
