Caution to be Taken When Brazing Refrigerant Piping
“Do not use flux when brazing copper-to-copper refrigerant piping. (Particularly for the HFC refrigerant
piping) Therefore, use the phosphor copper brazing filler metal (BCuP) which does not require flux.”
(Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux
is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant
oil. The use of flux is strictly forbidden since the cleaning on site is impossible.)
15.1.6 Drain Piping Work
(Caution) Keep in mind that if the phosphor copper brazing filler metal is used and the brazing temperature
and the heating time exceed a certain point, the phosphor changes into the gaseous state (e.g.
BCuP -1 to 5 : between 700 and 800°C) which causes pin holes and results in refrigerant
leakage.

Rig drain piping
•
Keep piping as short as possible and slope it downwards so that
air may not remained trapped inside the pipe.
WARNING Rig the drain pipe as shown below and take
measures against condensation, improperly
rigged piping could lead to leaks and eventually
wet furniture and belongings.
Connect the drain pipe as described below
•
It is necessary to clean the drainpan.
•
The drain pipe outlet can be either on the right or left side.
•
After making the connection, wrap the drain pipes completely with insulation.
•
When connecting the drain pipe to the outlet on the left side, remote the rubber plug and attached it to the outlet
on the right side.
•
Insulate the drain hose inside the building.
•
In order to prevent foreign matter from building up inside the piping, you should avoid curves as much as
possible, and arrange so the trap can be cleaned.
NOTE)
•
If installing central drain piping, install according to the following right figure.
C : 3PN00281-18T-6

After piping work is finished, check drainage flows smoothly.
•
Add approximately 1000 cc of water gradually and check drainage flow. (Fig. 13)
•
Make sure that water does not leak from the drain piping, connecting parts and the drain plug.

WHEN ELECTRIC WIRING WORK IS FINISHED
•
Check drainage flow during COOL running, explained under the section entitled TEST OPERATION.
