oily inside. The residual oil in copper tubes should be as little as possible. (Low residual
oil type copper tubes are used in the shipped units.)
7) Evacuation, Vacuum Pump and Refrigerant Charge [R134a/R404A]
Never allow the oil in the vacuum pump to flow backward. The vacuum level and
vacuum pump may be the same as those for the current refrigerants. However, the
rubber hose and gauge manifold to be used for evacuation and refrigerant charge
should be exclusively for R134a/R404A.
8) Refrigerant Leak Check
Refrigerant leaks can be detected by charging the unit with a little refrigerant, raising
the pressure with nitrogen and using an electronic detector. Do not use air or oxygen
instead of nitrogen for this purpose, or rise in pressure as well as in temperature may
cause R134a/R404A to suddenly react with oxygen and explode. Be sure to use
nitrogen to prevent explosion.
[b] REFRIGERANT RECOVERY
IM-21, 30, 45, 65, 100 (R134a)
No refrigerant access valve is provided in the unit. A tap valve should initially be tted
to the low-side process tube and be replaced with a proper access valve (see Fig. 12)
when recovery is completed.
Recover the refrigerant by using a refrigerant recovery machine (see its instruction
manual for proper operation), and store the refrigerant in a proper container. Do not
discharge the refrigerant into the atmosphere.
IM-130, 240 (R404A)
A low-side access valve is provided on an extension pipe connected to the suction port
of the compressor. A tap valve should initially be tted to the high-side process tube and
be replaced with a proper access valve (see Fig. 12) when recovery is completed.
Recover the refrigerant by using a refrigerant recovery machine (see its instruction
manual for proper operation), and store the refrigerant in a proper container. Do not
discharge the refrigerant into the atmosphere.
