Note: Do not remove the caps until you are ready to perform the
brazing process.
Remove Protective Caps
Remove the unit from the packaging. Gather all material
needed for brazing purposes.
Tools Needed For Brazing:
• Torch
• Brazing Rod
• Wet Rag
• Inspection Mirror
• Nitrogen Tank
Place both the 3/8 and the 1/4 copper couplings on the exposed
lines.
NOTE: Place a wet rag around the copper tubes
near the rubber grommet located at the rear of the
evaporator housing, this will minimize the possibility
of melting the grommet. Be sure to clear the power
cord and drain line from brazing area.
To prevent oxidizing, purge nitrogen into each
line. Braze each of the copper extensions to
the tubing coming out of the Evaporator Unit
(Fan Coil Unit). Perform a visual inspection and
pressurize test to 200 psig for 15 minutes to
verify there are no leaks.
