(2) Drill bolt holes and install bolts.
1) Stick the reference cardboard on the installation position; drill 4 holes according to the
hole site on the cardboard as shown in Fig 2; diameter of drilling hole is according to
the diameter of expansion bolt and the depth is 60-70mm(2-3/8~2-3/4 in.), as shown
in Fig 3.
Fig 2 Fig 3
2) Insert the M10 expansion bolt into the hole and then knock the nail into the bolt, as
shown in Fig 4.

NOTES!
The length of bolt depends on the installation height of the unit, bolts are field supplied.
Fig 4
(3) Install the indoor unit temporarily.
Assemble suspension bolt on the expansion bolt, attach the hanger bracket to the suspension
bolt. Be sure to fix it securely by using a nut and washer from upper and lower sides of the hanger
bracket. The washer fixing plate will prevent the washer from falling.
(4) The usage of paper pattern.

2.3 Drainage Pipe Installation and Drainage System Testing
2.3.1 Notice for Installation of Drain Pipe
(1) The drainage pipe should be short and the gradient downwards should be at least 1%~2%
in order to drain condensation water smoothly.
(2) The diameter of drainage hose should be bigger or equal to the diameter of drainage pipe
joint.
(3) Install drainage pipe according to the following fig and arrange insulation to the drainage
pipe. Improper installation may lead to water leakage and damp the furniture and other
things in the room.
(4) You can buy normal hard PVC pipe used as the drainage pipe. During connection, insert
the end of PVC pipe into the drainage hole and then tighten it with drainage hole and wire
binder. Can’t connect the drainage hole and drainage hole with glue.
(5) When the drainage pipelines are used for several units, the position of pipeline should be
about 100mm (4 in.) lower than the drainage port of each unit. In this case, thicker pipes
should be applied.
Fig.7
2.3.2 Drainage pipe installation
For easy drainage of the condensation water, the drainage pipe should be installed with a
downward gradient. To avoid the condensation, the connection pipe joint should be insulated with
thermal insulation material. A water seal should be employed as shown in Fig.8 and the height of
the water seal could be determined by the pressure of the drain hose.

Drain hose is in negative pressure state: A = B≥P/10+20 (mm).
Drain hose is in positive pressure state: A≥30mm，B≥P/10+20 (mm).
Note: P is the absolute pressure of the drain hose position, Pa.
Fig.8
2.3.3 Test of Drainage System
(1) Inject approximately 1L purified water to drain pan from air vent, ensure that not to splash
the water over the electrical components (e.g. water pump. etc.).
(2) During the test, please carefully check the drainage joint, make sure no any leakage occur.
(3) It is strongly recommend to do the drain test before ceiling decoration.

2.4 Installation of Air Duct
NOTES！
①There should be insulating layer on air-out duct, air-return duct and fresh air duct to avoid
heat loss and moisture. Adhere a nail on the air duct and then add thermal sponge with a
layer of tin. Fasten it with a nail cover and then seal the junction with tin tapes. You can
also use other materials that have good insulation quality.
②Each air-out duct and air-return duct should be fixed on a pre-made board with iron frame.
The junction of air duct should be well-sealed in order to prevent air leakage.
③The design and construction of air duct should comply with national requirements.
④The edge of air-return duct is suggested to be more than 150mm(5-7/8 in.) away from the
wall. Add a filter to the air-return opening.
