Installation Of Drainage Pipeline; Installation Of Refrigerant Pipe - Sharp GB-X18JR Operation Manual

UNIT INSTALLATION INSTRUCTIONS

Installation of drainage pipeline

The Drainage Pipeline shall be installed with an inclining angle of 5~0°, so as to facilitate the
•
drainage of condensate. The joints of the Drainage Pipeline must be covered by thermal insulation
materials to avoid generation of exterior condensate.
A Drainage outlet is located at both the left and right sides of the indoor unit. After selecting one
•
Drainage outlet, the other outlet shall be blocked by rubber plug. Bundle the blocked outlet with
string to avoid leakage, and also use thermal insulation materials to wrap the blocked outlet.
When shipped out from factory, both the Drainage outlets are blocked by rubber plugs.
•
When connecting the drainage pipe with the unit, do not apply excessive force to the pipeline at
•
the side of the unit. The fixing position of the pipeline shall be near the unit.
Purchase general-purpose hard PVC pipe locally to be used as the drainage pipeline. When
•
carrying out connection, place the end of the PVC pipeline into the drainage hole. Use flexible
drainage tube and tighten it with thread loop. Never use adhesive to connect the drainage hole
and the flexible drainage tube.
When the laid drainage pipe is used for multiple units, the common pipe shall be about 00mm
•
lower than the drainage outlet of each set of unit. A pipe with thicker wall shall be used for such
purpose.
Caution:
The joint of condensate pipe must not have leakage.
Testing of drainage system
 After the electrical installation is completed, carry out the testing of the drainage system.
2 During the test, check if the water correctly flows through the pipelines. Carefully observe the joints
to ensure that there is no leakage. If the unit is to be installed in a new house, carry out testing
before decorating the ceiling.

Note:
• The standard pipe length is 5m. If the pipe length exceed 5m, add refrigerant. (As shown in above
table)
• Use pipes with thickness 0.8mm(1/4˝, 3/8˝, 1/2˝), 1.0mm(5/8˝), 1.2mm(3/4˝). The pipe wall shall be
able to withstand the pressure of 6.0 MPa.
• The longer the refrigerant pipe, the lower the cooling effect and the heating effect.
