3. SELECTION PROCEDURE
• For details on the selection of the separation tube kits, refer to the Installation Manual supplied with the RB unit or the
DESIGN & TECHNICAL DATA
..
4. INSTALLATION PROCEDURE
CAUTION
• Do not mistake the direction of connection.
• Please do not install it in outdoor.
• For the restrictions of connection pipe, please follow the Installation manual of RB unit.
(1) Cut the indoor side pipe of the RB unit with a pipe cutter.
Liquid pipe : φ6.35 (1/4’’) → φ9.52 (3/8’’)
Gas pipe : φ12.7 (1/2’’) → φ15.88 (5/8’’)

NOTE: Insert the separation tube fi rmly until it touches the RB unit pipe.
CAUTION
• Use a pipe cutter to cut the pipe. When removing burrs after pipe cutting, make sure that loose particles do not get into the
pipe.
(2) Connecting the separation tube kit.
CAUTION
• Refer to the RB Unit Installation Manual for the list of RB unit separation tube kits that can be used for branch merging.
• If the pipe diameter of the separation tube kit does not match that of the mating pipe, use a reducer (included in the package).
• To connect an indoor unit with a capacity exceeding 18.0kW, two sets of UTP-EX060A and one set of UTP-EX096A are
required.

2 Fit the separation tube insulation on both sides of the separation tube, and fi x the groove and the overlap between the
separation tube insulation and the unit insulation with cable ties (available as accessories).
Make sure that the ends of the separation tube insulation closely fi t the RB unit.

: Cable tie installation is not necessary on the separation tube insulation for 4-port liquid pipe merging.
CAUTION
• Be sure to install the heat insulation on liquid pipes and gas pipes. Unless they are thermally insulated, water condensation
can cause accidents or reduction in performance.
• After installing the heat insulation, if you worry about possible condensation due to the high humidity of installation position,
please use locally procured heat insulation to reinforce insulation.
