Refrigerant pipe work (continued)
For GUG-02SL-E with PUHZ-ZRP71
1. Insert the flare nut in the field refrigerant piping, pull the insulating
material when performing flare pipe expansion, and put the
insulating material back so that the copper pipe is not exposed.
* Condensation may occur.

2. Wrap the insulating material around the flare connection and the
field refrigerant piping (no gap should exist) and temporarily fix using
the tape for piping construction. (It will be clipped by the insulating
pipes described in the step 3 to fix.)

3. Wrap the insulated pipe around the flare area and fix the each
insulating pipe with a tie band.
* Be sure to perform construction so as not to leave a gap on the
insulated pipe joint area. (Condensation may occur in the flared
area.)

4. Wrap the tape for piping construction around the joint between the
insulated pipe and the field refrigerant piping to prevent the insulated
joint from being exposed.

For GUG-02SL-E with PUHZ-ZRP50
Use Φ12.7 mm for gas pipe and Φ6.35 mm for liquid pipe.
Both PAC-SH30RJ-E and PAC-SH50RJ-E are necessary.
1. Attach PAC-SH30RJ-E and PAC-SH50RJ-E to refrigerant pipes of
Dx-coil unit. For details, refer to their manual.
2. Insert the flare nut in the field refrigerant piping, pull the insulating
material when performing flare pipe expansion, and put the
insulating material back so that the copper pipe is not exposed.
* Condensation may occur.
