O AVOID POSSIBLE DAMAGE TO PIPING
:
-C
OOL THE FILTERS AND VALVE BODY WITH A WET CLOTH AND MAKE
SURE THE BODY TEMPERATURE DOES NOT EXCEED
248°F (120
DURING BRAZING
.
-E
NSURE THAT THE OTHER PARTS
(
SUCH AS ELECTRICAL BOX
,
TIE
WRAPS AND WIRES
)
ARE PROTECTED FROM DIRECT BRAZING FLAMES

WARNING
7. After brazing, put the lower pipe insulation back in place and
close it with the upper insulation cover (after pealing off the
liner).
8. Secure the pipe fixing clamp (C) in place again 2 x 10-32”
(M5).
9. Make sure that field pipes are fully insulated. Field pipe
insulation must reach up to the insulation you have put back
in place as per procedure step 7. Make sure that there is
no gap between both ends in order to avoid condensation
dripping (finish the connection with tape eventually).
