Use bolts to secure the unit to a flat, solid floor.
When mounting the unit on a wall or the roof, make
sure the support is firmly secured so that it cannot
move in the event of intense vibrations or a strong
wind.
Do not install the outdoor unit in pits or air vents
Installing the pipes
Use suitable connecting pipes and equipment for the
refrigerant R410A.
INSTALLER
Install the drain fitting and the drain hose(for
model with heat pump only)
Condensation is produced and flows from the outdoor unit
when the appliance is operating in the heating mode. In order
not to disturb neighbours and to respect the environment,
install a drain fitting and a drain hose to channel the condensate water. Install the drain fitting and rubber washer on the
outdoor unit chassis and connect a drain hose to it as shown
in the figure.

refrigerant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and 3-
way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling. Stop
the vacuum pump.

Owner's Manual
Commercial Air Conditioners
Model: ISMI-C24
Thank you for choosing Commercial Air Conditioners, please read this
owner’s manual carefully before operation and retain it for future reference.
User Notice
The total capacity of the indoor units which runs at the same time can not exceed 150% of
◆
that of outdoor units; otherwise, the cooling (heating) effect of each unit would be poor.
A breaker (or fuse) needs to be installed in every indoor unit, and the capacity should be in
◆
accordance with indoor unit’s electrical parameter; all the indoor units are required to be centralized
controlled by a main switch, this switch can cut off the electric power supply in case of emergency.
The breaker (or fuse) on each indoor unit has the function of preventing short circuit and avoiding
abnormal overload, it should be connected in normal situation. The main switch controls the power
supply of all the indoor units. Before cleaning and maintaining the indoor units, it is very important
to turn off the main power supply switch.
In order to turn on the units successfully, the main power switch should be opened 8 hours
◆
before the operation.
It is a normal phenomenon that the indoor unit will still run for 20-70 seconds after the indoor
◆
unit receives the "stop" signal so as to make full use of after-heat for the next operation.
When the running modes of the indoor and outdoor units conict, it will be indicated on the
◆
display of the wired controller in ve seconds and 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 HEAT mode conicts with each of the COOL mode, DRY
mode and FAN mode, while the COOL mode, DRY mode and FAN mode are compatible between
each other.
The appliance shall not be installed in moist places, such as laundry.
◆
An all-pole disconnection switch having a contact separation of at least 3mm in all poles
◆
should be connected in xed wiring.
Main switch is provided by end user. Main switch knob should be in black or gray, it can be
◆
locked on “OFF” with padlock.
The instruction of main power switch should be included in user manual and the
◆
recommended installing height should be at 0.6-1.7m. And also over current protection is required
(UL 1995,CSA C22.2).
The outdoor ambient temperature of the unit under cooling mode ranges from -5~48°C DB.
◆
The outdoor ambient temperature of the unit (only for the heat pump type unit) under heating mode
ranges from -15~27°C WB.
This appliance is not intended for use by persons (including children) with reduced physical,
◆
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
This product must not be disposed together with the domestic waste. This product has
to be disposed at an authorized place for recycling of electrical and electronic appliances.
Thank you for selecting Impecca air conditioner. Before use, please read this

Warning:
Do not adopt fuse with unsuitable capacity or adopt iron wire instead of fuse, otherwise
◆
malfunction or re may happen.
Turn off the main power switch immediately if malfunction (such as smell the burning odor
◆
etc.) happens.
Keep good ventilation in the room to avoid oxygen decit.
◆
Don’t insert nger or stick-like objects into the air inlet/outlet grille.
◆
Please install the unit in a place where is strong enough to withstand the weight of the unit;
◆
otherwise, the unit would fall down and cause injury or death.
Don’t apply or spray and paint or insecticide on the surface of unit, otherwise, fire may
◆
happen.
Never ret the unit and contact the sales agent or the professional installation personnel for
◆
the repair or relocation of the unit.
An all-pole disconnection switch having a contact separation of at least 3mm in all poles
should be connected in xed wiring.
Note:
Before using the unit, please check if the piping and wiring are correct to avoid water
◆
leakage, refrigerant leakage, electric shock, or re etc.
The main power supply must be earthed soundly to avoid the hazard of electric shock and
◆
never connect this earth wire to the gas pipe, running water pipe, lightening rod or phone cable's
earth lead.
Turn off the unit after it runs at least ve minutes; otherwise its service life will be shortened.
◆
Don’t allow children operate the air conditioner.

2.2 Installation Location of the Indoor Unit
(1). Obstruct should be taken away from the inlet or outlet of the indoor unit so that the airow
can be blown though all the room.
(2). Ensure the installation work is done as per the schematic diagram of installation spaces.
(3). Select a place where is strong enough to withstand 4 times of the weight of the indoor unit;
otherwise it would incur vibration and noise.
(4). Ensure the installation place is at horizontal level.
(5). Select a place where the condensate water is easily drained out and the drain pipe can be
easily connected with outdoor unit.
(6). Make sure that there is enough space for care and maintenance. Make sure that the
distance between the indoor unit and ground is above 1800mm.
(7). When installing the steeve bolt, check if the installing place can stand 4 times of the weight
of the units. If not, reinforce before installation. (Refer to the installation cardboard and nd
where should be reinforced)
Note!
There will be lots of lampblack and dust sticking 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
Flex Series for North America
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:
To guarantee the good performance, the unit must be installed by technician according with
◆
this instruction.
◆ Please contact the local Impecca special nominated repair department before installation.
Any
malfunction caused by the unit that is installed by the department that is not special nominated
by Impecca would not deal without time by the inconvenience of the business contact.

2.5 Main Body of Hoisting Air Conditioner
(1). The primary step for installing the indoor unit.
When attach the hoisting stand with hoisting screw, do use nut and gasket respectively at
◆
the upper and lower of the hoisting stand to x it. The use of gasket anchor board can prevent
gasket from breaking off.
(2). Use installation cardboard
Please refer to the installation cardboard about the dimension of ceiling opening.
◆
The central mark of the ceiling opening is marked on the installation cardboard.
◆
Install the installation cardboard on the unit by bolts (3 pieces), 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.4)
(4). Check if the unit is horizontal.
Inner drainage pump and oat switch are included in the indoor unit, check if 4 angle of
◆
every unit are horizontal by water level. (If the unit is slant toward the opposite of the coagulate
water ow, there may be malfunction of the oat switch and lead water drop.)
(5). Back-out the gasket anchor board used to prevent gasket from breaking off and tighten the
nut on it.
