York YOCC-YOHC 12-60 - Manual (Page 2)

• The drain pipe of indoor unit must be heat insulated, or it will condense dew,
as well as the connections of the indoor unit.
• Hard PVC binder must be used for pipe connection, and make sure there is no
leakage.
• With the connection part to the indoor unit, please be noted not to impose
pressure on the side of indoor unit pipes.
• When the declivity of the drain pipe downwards is over 1/100, there should not
be any winding.
• The total length of the drain pipe when pulled out traversely shall not exceed
20m, when the pipe is over long, a prop stand must be installed to prevent
winding.
• Refer to the fi gures on the right for the installation of the pipes.
INSTALLATION IN THE FOLLOWING PLACES
MAY RESULT IN TROUBLE
INDOOR UNIT INSTALLATION
Installing Ø10 hanging screw bolts. (4 bolts)
• Please refer to the following fi gure for the distance measurement between the
screw bolts.
• Please install with Ø10 hanging screw bolts.
• The handling to the ceiling varies from the constructions, consult the construction
personnels for the specifi c procedures.
1. The size of the ceiling to be handled ... ... do keep the ceiling fl at. Consolidate
the roof beam for possible vibration.
2. Cut off the roof beam.
3. Strengthen the place cut off, and consolidate the roof beam.
• Carry out the pipe and line operation in the ceiling after fi nishing the installation
of the main body. While choosing where to start the operation, determine the
direction of the pipes to be drawn out. Especially in case there is a ceiling, position
the refrigerant pipes, drain pipes, indoor & outdoor lines to the connection places
before hanging up the machine.
• The installation of hanging screw bolts.
Installation of the indoor unit in direct sun light. Installation in the unit in wrong direction.
Installation of outdoor units too close or,
blowing discharged air into each other. Installation of the indoor unit in a place where
there is an obstacle near the air inlet or outlet.
Installation of the outdoor unit in a place
exposed regularly to a strong wind.
> 30 cm
Installation of the indoor unit at too high > 30 cm
a position.
CEILING INSTALLATION
1. Remove the side board and the grille. (Refer to Chart 8)
(For models 48000 and 60000 Btu/h, do not remove the grille.)
2. Locate the hanging arm on the hanging screw bolt. (Refer to Chart 9)
Prepare the mounting bolts on the unit. (Refer to Chart 10)
3. Hang the unit on the hanging arm by sliding backward. Securely tighten the
mounting bolts on both sides. (Refer to Chart 9)

CONNECT THE DRAIN PIPE
1. Install indoor unit drain pipe
The outlet has PTI screw thread, Please use sealing materials and pipe sheath
(fi tting) when connecting PVC pipes.
Cautions
2. Drainage test
• Check whether the drainpipe is unhindered
• New built house should have this test done before paving the ceiling.
3. Drain Elbow Installation
Fit the seal into the drain elbow, then insert the drain elbow into the base pan
hole of outdoor unit, rotate 90° to securely assemble them. Connect the drain
elbow with an extension
drain hose (Locally purchased),
in case of the condensate
draining off the outdoor unit
during the heating mode.

WIRING
■ Attaching wiring
1. The air conditioner should use separate power supply with rated voltage
2. The external power supply to the air conditioner should have ground wiring,
which is linked to the ground wiring of the indoor and outdoor unit.
3. The wiring work should be done by qualifi ed persons according to circuit
drawing.
4. A leakage protector should be installed according to the National Standard
concerning electrical appliance.
5. Be sure to locate the power wiring and the signal wring well to avoid cross-
disturbance and their contact with connecting pipe or stop valve body.
6. The wiring attached to this air conditioner is 10m long. Be sure to prolong it
with wiring of the same type and proper length if necessary. Generally, do not
twist two wiring together unless the joint is soldered well and covered with
insulator tape.
7. Do not turn on the power until you have checked carefully after wiring.
