Set Engine Rotational Speed - Panasonic U-16GE2E5 Main Parts Replacement

Pump Down Procedure (Common to Cooling and Heating)

8. Set engine rotational speed

Set an engine rotational speed that is suitable for the pump-down.
(1) Follow the procedure of 6-(1) to select "
(2) Press the UP (S005) / DOWN (S006) key and select
menu item number "
display "
(3) Press the SET (S007) key. The LEVEL LED
(D053) will be illuminated and settings such as
the set engine rotational speed will be displayed at
1-second intervals as shown below.
(The table below shows an example.)
(4) If you press the SET (S3) key again for 1 second
or more, the forced engine rotational speed setting
will be enabled and the TEST/WARNING LED
(D052) will be illuminated.
(5) In this state, use the UP (S005) key or DOWN
(S006) key to change the forced engine rotational
speed. Refer to the following for the number of
rotations to set.
• Set RPM: 800 to 1,000[min
Caution: The forced engine rotational speed can be set in increments of 100 revolutions. A setting that exceeds
the above number of revolutions is possible, but to protect the equipment, do not exceed the above range.
Furthermore, if the compressor inlet pressure is 0.05 MPa or less, the set number of revolutions may be
automatically reduced.
