User Notice
◆ When operating, the entire capacity of the cooperating indoor unit should be not
larger than 150% of outdoor unit. Otherwise, it will cause the shortage of cooling
(heating) capacity.
◆ A Breaker (or fuse) need to be installed in every indoor unit, and the capacity
should in according with indoor unit’s electrical parameter, all the indoor units are
required to be centralized controlled by a total Switch, this Switch can cut off the
electric power supply in case of emergency. The Breaker (or fuse) on each indoor
units have the function of short circuit prevention and abnormal overload avoiding,
it should be connected in normal situation. The total switch controlling the power
supply of all the indoor units. Before clearing and maintenance job being carried
out to the indoor units, it is very important to turn off the total power supply switch.
◆ In order to turn on the units successfully, the main power switch should be opened
8 hours before the operation.
◆ After receiving the turn off signal, every indoor unit will continue to work for
20-70sec to make use of the rest cool air or the rest heat air in the heat exchanger,
while preparing for the next operation. And this is normal.
◆ When the selected operating mode of the indoor unit are clash with the operating
mode of the outdoor unit, the malfunction light will blink after 5s on the indoor unit
or remote controller showing that the operation clash, then the indoor unit will stop.
At this time, change the operation mode of the indoor unit to the one that would
not clash with the outdoor operating mode to make the operation normal. The
cooling mode is not clash with the dry mode, while the fan mode is not clash with
any mode.
◆ The appliance shall not be installed in the laundry

2 Install Of The Cassette Type Indoor Unit
2.1 Schematic diagram of installation spaces
Fig.1
2.2 Select install location of the indoor unit
1). Obstruct should put away from the intake or outlet vent of the indoor unit so
that the airflow can be blown though all the room.
2). Make sure that the installation had accord with the requirement of the
schematic diagram of installation spaces.
3). Select the place where can stand 4 times of the weight of the indoor unit and
would not increase the operating noise and oscillate.
4). The horizontally of the installation place should be guaranteed.
5). Select the place where easy drain condensated coagulated water, and easy
connect with outdoor unit.
6). Make sure that there are enough space for care and maintenance. Make sure
that the weight between the indoor unit and ground is above 2500mm.
7). When installing the steeve bolt, check if the install place can stand the weight
4 times of the unit’s. If not, reinforce before installation. (Refer to the install
cardboard and find where should be reinforced).
2
Free Match Series Cassette Type Indoor Unit
Note! :
There will be lots of lampblack and dust stick on the acentric, heat exchanger and
water pump in dining room and kitchen, which would reduce the capacity of heat
exchanger, lead water leakage and abnormal operation of the water pump. The
following treatment should be taken under this circumstance:
①. Ensure that the smoke trap above cooker has enough capacity to obviate
lampblack to prevent the indraft of the lampblack by the air conditioner.
②. Keep the air conditioner far from the kitchen so that the lampblack would not
be indraft by the air conditioner.
2.3 Important notice:
1). To guarantee the good performance, the unit must be installed by professional
personnel according with this instruction.
2). Please contact the local ALPICAIR special nominated repair department before
installation. Any malfunction caused by the unit that is installed by the
department that is not special nominated by ALPICAIR would not deal with on time
by the inconvenience of the business contact.
2.4 Dimension of ceiling opening and location of the
hoisting screw (M10)
Fig.2 Install dimension of mode
3
Unitary Duct Split Unitary Duct Split
The drilling of holes in the ceiling must be done by the professional personnel.
Fig.3
Notes :
The dimension for the ceiling openings with * marks can be as large as 910mm.
But the overlapping sections of the ceiling and the decorated surface boards should be
maintained at no less than 20mm.
2.5 Main body of hoisting air conditioner
1). The primary step for install the indoor unit.
When attach the hoisting stand on hoisting screw, do use nut and gasket
individually at the upper and lower of the hoisting stand to fix it. The use of gasket
anchor board can prevent gasket break off.
2). Use install cardboard
a) Please refer to the install cardboard about the dimension of ceiling opening.
b) The central mark of the ceiling opening is marked on the install cardboard.
c) Install the install cardboard on the unit by bolt (3 piece), and fix the angle of
the drainage pipe at the outlet vent by bolt.
3). Adjust the unit to the suitable install place. (Refer to the fig.3)
4). Check if the unit is horizontal.
Inner drainage pump and bobber switch are included in the indoor unit, check if 4
angle of every unit are horizontal by water lever. (If the unit is slant toward the opposite
of the coagulate water flow, there may be malfunction of the bobber switch and lead
water drop.)
5). Backout the gasket anchor board used to prevent gasket break off and tighten
the nut on it.
6). Backout the install cardboard.
4
Free Match Series Cassette Type Indoor Unit
Fig.4
Note! :
Please do tighten the nuts and bolts to prevent air conditioner break off.
2.6 Connection of the refrigerant pipe
1). When connect the pipe to the unit or backout it from the unit, please do use
both spanner and torque wrench. As shown in fig.5.
2). When connect, smear both inside and outside of the flare nut with freeze
motor oil, screw it by hand and then tighten it with spanner.
3). Refer to form 1 to check if the wrench had been tightened (too tight would
mangle the nut and lead leakage).
4). Examine the connection pipe to see if it had gas leakage, then take the
treatment of heat insulation, as shown in the fig.5.
5). Only use median sponge to entwine the wiring interface of the gas pipe and
heat preservation sheath of the gas collection tube.
