Gas leak inspection
Use a leak detector manufactured specially for
HFC refrigerant (R32, R410A, R134a, etc.) to
perform the R32 gas leak inspection.
* Leak detectors for conventional HCFC
refrigerant (R22, etc.) cannot be used, as the
sensitivity drops to approximately 1/40 when
used for HFC refrigerant.
• R32 has a high working pressure, so failure to
perform the installation work properly may result in
gas leaks such as when the pressure rises during
operation. Be sure to perform leak tests on the piping
connections.

■ Insulating the pipes
• The temperatures at both the liquid side and gas side
will be low during cooling so in order to prevent
condensation, be sure to insulate the pipes at both of
these sides.
• Insulate the pipes separately for the liquid side and
gas side.
REQUIREMENT
Be sure to use an insulating material which can
withstand temperatures above 120°C for the gas side
pipe since this pipe will become very hot during heating
operations.

■ To fix the fluorinated
greenhouse gases label
This product contains fluorinated greenhouse gases.
Do not vent gases into the atmosphere.
Contains fluorinated greenhouse gases
• Chemical Name of Gas
• Global Warming Potential (GWP) of Gas
CAUTION
1. Stick the enclosed refrigerant label adjacent to the
service ports for charging or recovering location and
where possible adjacent to existing nameplates or
product information label.
2. Clearly write the charged refrigerant quantity on the
refrigerant label using indelible ink. Then, place the
included transparent protective sheet over the label
to prevent the writing from rubbing off.
3. To prevent emission of the contained fluorinated
greenhouse gas, ensure that the fluorinated
greenhouse gas is never vented to the atmosphere
during installation, service or disposal. When any
leakage of the contained fluorinated greenhouse gas
is detected, the leak shall be stopped and repaired as
soon as possible.
4. Only qualified service personnel are allowed to
access and service this product.
5. Any handling of the fluorinated greenhouse gas in
this product, such as when moving the product or
recharging the gas, shall comply under (EU)
Regulation No. 517/2014 on certain fluorinated
greenhouse gases and any relevant local legislation.
6. Periodical inspections for refrigerant leaks may be
required depending on European or local legislation.
7. Contact dealers, installers, etc., for any questions.
