Note (1)
Place the concrete
foundation
deep enough.
Connecting method
Apply refrigerant oil at half union as large and flare nut.
To bend a pipe, give the roundness as possible not to
crush the pipe.
When connecting pipe, hold the pipe centre to centre
then screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands
enter the pipe.
(4) Piping connection (Fig.26)
Note (1)
Give enough room for the concrete
foundation to fix anchor bolts.

(2) Piping size
Install the removed flare nuts
to the pipes to be connected,
then flare the pipes.

One way piping length: Less than 15 mm
Vertical height difference: Less than 5 m
(3) Limitations for one way piping length and vertical
height difference.
Precautions for refrigerant piping
(Fig. 26)
Do not twist or crush piping.
Be sure that no dust is mixed in piping.
Bend piping with as wide angle as possible.
Keep insulating both gas and liquid piping.
Check flare-connected area for gas leakage.
Forced fastening without
centering may damage the
threads and cause a gas
leakage.
(5) Purging mehtod ( the refrigerant is R407C )
Install the unit so that the angle of inclination must be less than
3 degrees.

Detach the service port's cap of 3-way valve, the
valve rod's cap for 2-way valve and 3-way's, connect
the service port into the projection of charge hose
(low) for gaugemanifold. Then connect the projection
of charge hose (center) for gaugemanifold into
vacuum pump.
