2. Do not use flux when brazing refrigerant piping.
Use phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) that does
not require flux.
(If chlorinated flux is used, the piping will be corroded and, in addition if fluorine is contained, the refrig-
erant oil will be deteriorated and the refrigerant circuit will be affected badly.)
3. When carrying out leakage test of refrigerant piping and the indoor unit after the installation of indoor unit
is finished, confirm the connecting outdoor unit installation manual for test pressure.
Refer to also the outdoor unit installation manual or technical document for refrigerant piping.
4. In case of refrigerant shortage due to forgetting additional refrigerant charge etc., it will result in malfunc-
tion such as does not cool or does not heat.
Refer to the outdoor unit installation manual or technical document for refrigerant piping.
CAUTION
Do not use antioxidant when brazing piping
It may result in malfunction of components and clogging of piping due to residue.
7. DRAIN PIPING WORK
(1) Carry out drain piping.
Carry out drain piping so that drainage can ensured.
• Select the piping diameter equal to or larger than (except for riser) that of the connection piping (polyvi-
nyl chloride piping, nominal diameter 25mm, outside diameter 32mm).
• Install the drain piping as short as possible with downward inclination of 1/100 or more and without
where air may stagnate. (Refer to Fig. 11) (It may cause abnormal sound such as bubbling noise)
CAUTION
If drain stagnates in the drain piping, the piping may be clogged.
• If sufficient downward inclination cannot be ensured, carry out upward drain piping.
• Install supports at a distance of 1 to 1.5m so that the piping may not deflect. (Refer to Fig. 11)
• Make sure to use the attached drain hose (1) and the metal clamp (2).
Insert the drain hose (1) into the drain socket up to the point where the socket diameter becomes larger.
Put the metal clamp (2) to the taped hose end and tighten the metal clamp (2) with torque 1.35±0.15N·m
(135±15N·cm).
