10-4-9. Check and Test Operation
For R410A, use the leak detector exclusively
manufactured for HFC refrigerant (R410A,
R134a, etc.).
* The conventional leak detector for HCFC refriger-
ant (R22, etc.) cannot be used because its sensi-
tivity for HFC refrigerant lowers to approx. 1/40.
• Pressure of R410A becomes approx. 1.6 times of
that of R22. If installation work is incompletely
finished, a gas leakage may occur in the cases
such as pressure
rise during operation. Therefore, be sure to test
the piping connections for leaking.
• Service port cap
connection
• Valve stem cap
connection
• Check the flare nut connections, valve stem cap
connections and service port cap connections for
gas leak with a leak detector or soap water.
• Use a circuit breaker of a type that is not
tripped by shock waves.
• If incorrect/incomplete wiring is carried out, it
will cause an electrical fire or smoke.
• Prepare the power supply for exclusive use
with the air conditioner.
• This product can be connected to the mains.
Connection to fixed wiring :
A switch or circuit breaker which disconnects
all poles and has a contact separation of at
least 3 mm must be incorporate in the fixed
wiring.
An approved short circuit breaker or
switches must be used.
* (A breaker having a sensitivity of approxi-
mately 0.1 second or less and a capacity
of approximately 30 mA is usually used.)
