SAFETY INSTRUCTIONS
Important!
•
Carefully read the instructions before operating the unit.
•
This appliance comprises of an indoor and an outdoor unit. The indoor slim evaporator is
designed exclusively for indoor floor, wall or ceiling installations while the external condenser
should be installed outside while still away from flood water or snow line.
•
Rating: This unit must be only connected to a 220-240 V / 50 Hz earthed power source.
•
Installation must be in accordance with the regulations of the country where it is used.
•
European Union regulations requires for an F-Gas trained engineer to handle any operation
where non-qualified intervention could cause fluorinated gas escape. A commissioning
certificate must be issued with any installation.
•
This air conditioner contains R32 which is a safe efficient refrigerant which has a lower
environmental burden than traditional refrigerants.
•
The refrigerant used in this air conditioner is an environmentally friendly hydrocarbon R32,
which has a very low Global Warming Potential compared to traditional refrigerants.
•
R32 is classed as slightly flammable and as such naked flames and sources of ignition
should be kept a safe distance from the unit.
•
If you are in any doubt about the suitability of your electrical supply have it checked and, if
necessary, modified by a qualified electrician.
•
This air conditioner has been tested and is safe to use. However, as with any electrical
appliance - use it with care.
•
Disconnect the power before dismantling, assembling or cleaning.
•
Avoid touching any moving parts within the appliance.
•
Never insert fingers, pencils or any other objects through the guard
•
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities. It is also not intended for use by those with a lack of experience
and knowledge, unless they have been given supervision or instruction concerning the use of
the appliance by a person responsible for their safety. Do not leave children unsupervised
with this appliance.
•
Do not clean the unit by spraying it or immersing it in water.
•
Never connect the unit to an electrical outlet using an extension cord. Both the indoor and
outdoor units must be hardwired by a qualified electrician.
•
Never operate this appliance if the cord is damaged. Ensure the power cord is not stretched
or exposed to sharp objects / edges.
•
A damaged supply cord should be replaced by the manufacturer or a qualified electrician in
order to avoid a hazard.
•
Any service other than regular cleaning or filter replacement should be performed by an
authorized service representative or a qualified air conditioning engineer. Failure to comply
could result in a voided warranty.
•
Do not use the appliance for any purpose other than its intended use.
•
The outdoor part of the air conditioner unit must always be stored and transported upright,
otherwise irreparable damage may be caused to the compressor; if in doubt we suggest
waiting at least 24 hours before starting the unit.
•
Avoid restarting the air conditioner unless 3 minutes have passed since being turned off.
This prevents damage to the compressor.
•
Never use the mains as a switch to start and turn off the air conditioning unit. Use the
provided ON/OFF button located on the remote control.
•
Always place the unit on a dry and stable surface. Install the outdoor unit on a wall with wallmounted brackets or fix on floor slab with special floor mounting slab or brackets.

Energy Saving and Unit Safety Protection Tips
•
Do not cover or restrict the airflow from the outlet or inlet grills both on the indoor and outdoor
units.
•
For maximum performance, the minimum distance from a wall or objects should be 50cm.
•
Keep the filters clean. Under normal conditions, filters should only need cleaning once every
four weeks (approximately). Since the filters remove airborne particles, more frequent
cleaning maybe necessary, depending on the air quality.
•
For the initial startup set the fan speed to maximum and the thermostat to 4-5 degrees lower
than the current temperature. After, set the fan switch to low and set the thermostat to your
desired setting.
•
To protect the unit we recommend not using the cooling function when the ambient indoor
temperature is higher than 35℃.
•
To protect the unit we recommend not using the heating function when the indoor ambient
temperature is lower than 7℃.
•
Note the manufacturer operating temperature ranges at the end of this user manual.

HOW AIR SPLIT CONDITIONERS WORK
COOLING MODE
The compressor (6) in the external unit compresses the refrigerant into a high-temperature, highpressure gas. When this gas flows along the cooling fins of the condenser (7), heat is exuded and
the gas condenses into a liquid, which is then led to the evaporator (1) in the indoor unit. The liquid
expands into a gas at a low temperature and low pressure. This gas absorbs the warmth of the air
in the room, and a fan (3) draws the air through the filter and over the evaporator (1), blowing the
cooled air back into the room. The heat is moved to the compressor along with the gas. A fan (8)
draws air over the condenser and blows the warm air away.

8. Condenser Fan
HEAT PUMP MODE
The system operates in reverse: the condenser works as an evaporator, the evaporator as
a condenser: warm air is blown into the room. It is ideal as a maintenance heating when
outside temperature is not too low and when the indoor temperature is more than 7°C.
DEHUMIDIFYING
As with cooling, the moisture in the air condenses on the cold evaporator at room
temperature acting as a powerful dehumidifier.

IMPORTANT INFORMATION
AUTO RESTART
The air conditioner will automatically restart when electricity is restored after a power cut. If in
doubt, check the settings.
RANGE OF INTERNAL THERMOSTAT
The internal thermostat can be set at a desired temperature between 16 and 32°C. Note that
whether the desired value is achieved depends on the room size, temperature and insulation
of the room.
RANGE OF HEAT PUMP FUNCTION
The heat function can be used when the external ambient temperature is above -15°C. The
performance of the heat pump will degrade with lowering external temperatures. Please note
the performance will reduce when the outdoor temperature drops below 5°C.
CAPACITY
The required cooling or heating capacity depends greatly on the location and/or use of the
room where the air conditioner is installed. Strong sunlight and the presence of people, lights
or equipment creates an additional heat load. Normal living spaces require about 350 Btu per
square metre of floor surface. In strong sunlight or if other sources of heat are present, this
may be as much as 1200 Btu per sqm.
Tip: On warm days, let the air conditioner cool the room as much as possible during the night
and keep the temperature constant from night to daytime.
13

obstruction, ensuring that
there is good airflow through
the whole air- conditioned
space. Select a position
where the condensing water
can be easily drained out,
and the indoor unit can be
easily connected to outdoor
unit.
The wall or ceiling where
the unit is fixed should be
strong enough to withstand the full weight and vibration of the unit. You can use specialised ceiling
mounting brackets (not supplied) if installed in the ceiling void. The unit should be accessible for
service and maintenance. The air conditioner must not be installed in a wet environment such as
a bathroom, shower or swimming pool etc.
Make sure that there is a minimum of 35 mm clearance in all directions A, B, C.
When outdoor unit is installed higher than indoor unit, in order to avoid water getting into the
room from the connecting pipe, you should make a curved bend (the curve face down) at the
connecting pipe before it gets through the wall to the indoor room, make sure the vertex is
outdoor.
When the outdoor unit is installed higher than indoor unit, in order to avoid water leakage
please ensure the drain pipe is using the gravity fall straight down or use an inline uplift
pump. If there is more than 5 meters differential a loop should be used.
When drilling through the wall ensure a 2-5 degrees angle, as shown in the picture bellow

INSTALLING THE INDOOR UNIT
• Select the location of the internal unit, determining the fixing direction and where the
pipework will go.
• Check that the wall where the pipework will be placed through is clear of any wiring or other
internal pipework or structures, before drilling a 90mm diameter hole (slanted slightly
downwards).
• Cut the through wall pipe to the desired length and then place it in the drilled hole.
CEILING MOUNTING
• The mounting surface should be solid brick, concrete or other equivalent strength structure
with sufficient loading capacity. Failing this you must take reinforcing, bracing andvibration
reduction measures.
• Install the 4, 10mm lifting bolts in the ceiling, noting the correct procedure for the type of
ceiling being fitted to.
• Lift the indoor unit into place using the necessary lifting equipment.
• Ensure the unit is perfectly horizontal as failure to do so may cause water leakage during
operation..
•
20
• Once the indoor unit is hung in place, the wiring and pipework can be connected. If space is
tight you may need to fit the copper pipes, drain pipes, control and electrical wires before you
permanently hang the indoor unit
The installation steps for embedded style are basically the same with the hanging style, but
remove the left and right panels of the indoor unit and then embed half of the unit body into the
ceiling showing up only the back panel and top panel.
21
ALTERNATIVE CEILING MOUNTING METHOD USING LIFTING BOLTS
Matching the structure of the ceiling, set the thread pitch based on the size of this unit as bellow
WOODEN STRUCTURES STEEL SKELETON STRUCTURES
Place the square bar on the girders and install the lifting bolts. Set directly on the supporting steel
Different type of bolts or inserts can be also used.
22
FLOOR / WALL MOUNTING
For floor or wall mounting use embedded or expandable bolts strong enough for the type of wall.
Install the unit with the control panel facing up similar to a radiator and make sure it is correctly
aligned and level.
Make sure that the drain pipe is underneath the pipelines. (When the drain pipe passes the room
interior, some condensed water might occur to its surfaces if the humidity is very high).
Tidy up the copper pipes, electrical cables and water drains and pass them through the piping
wall hole drilled before.
Notes:
1.
Either the indoor unit or the outdoor
unit can be higher, but the height
difference must comply with a max. 5
metres level difference.
2.
Try to reduce the bending of the pipes
as much as possible so as to avoid
possible negative impacts upon the
performances of the unit.
3.
Unit can be installed both vertical (floor
or wall mounting – fig1) or horizontal
(ceiling or embedded mounting – fig2).
Run the pipes on the back of the indoor
unit according to the install type
23
INSTALLATION OF THE OUTDOOR UNIT
• Try to move the product to the installation location in its original packaging.
• As the gravity centre of the unit is not at the installation centre, special caution should be
taken when using hoisting cables to lift it up
• During transport, the outdoor unit must not be tilted to over 45 degrees (also do not store
the unit horizontally.
• Use expansion bolts to fix the mounting supports on the wall.
• Use bolts and nuts to fix the outdoor unit firmly on the supports and keep on the same level.
• If the unit is installed on the wall or at the rooftop, the supports have to be firmly fixed so as
to resist earthquake or strong wind.

PIPELINES CONNECTION & AIR PURGING
No dust or any other particles, air or moisture should be
allowed to enter the air conditioning system. Careful attention
should be paid when pipeline connection for outdoor unit is
made. Try to avoid repeated curves as much as possible;
otherwise, damage to the copper pipes may occur. Suitable
wrenches should be used when the pipeline connection is
done so as to ensure appropriate torque (refer to torque
table).
Excessive torque action might damage the joints while too
little torque might lead to leakage.
Minimum bent radius 100 mm
Peel about 10 cm - 15cm of the thermal insulation sleeve in
out-pipe and in-pipe of indoor unit in preparation for pipe
connections. First connect the low-pressure pipe and after this
the high-pressure pipe. Press the surface of the pipe against
the connector vertically, twist the connectors to the bottom of
the bolt and finally tighten them with a torque wrench.
AIR PURGING WITH VACUUM PUMP
1.
Check that pipelines connection have been
properly connected, remove the charging port
cap, and connect the manifold gauge and the
vacuum pump to the
charging valve using
service hoses as shown
2.
Open the valve on the low-pressure side of
manifold gauge, then run the vacuum pump.
Vacuum the indoor unit and the connecting
pipes until the pressure in them lowers to below
1.5mmHG (The operation time for vacuuming is
about 10 minutes). When the desired vacuum is
reached, close the valve of the low pressure of
the manifold and stop the vacuum pump.
3.
Disconnect the service hoses and fit the cap to
the charging valve.
4.
Remove the blank caps, and fully opens the
spindles of the 2-way and 3-ways valves with a
service valve wrench.
5.
Tighten the blank caps of the 2-way and 3-
ways valves, following the torque table

ADDING REFRIGERANT
Units are pre-gassed for up to 5 meters of pipe. Refrigerant must be added if the pipework
measures more than 5 metres (16'5") in length. This operation can only be performed by a
professional F-Gas engineer, for the additional gas amount, see the below

OIL RETURN ELBOW
When the height difference between the indoor and outdoor unit is greater than 5m, in
order to allow oil to return to the compressor, an oil return elbow must be used. See
diagrams below for examples:

If oil return elbow radius R ≤100mm, oil return elbows must be located per 5 m as
shown; when the height difference between indoor and outdoor unit exceeds five
meters, oil reserve elbow and backstop elbow should be set according to the
relative position of outdoor unit and indoor unit. Make sure that the copper pipes
are not kinked or bent.
GAS LEAKAGE INSPECTION
After the pipeline connection is done, use a leakage inspection device to carefully check if
there is any leakage at the joints. This is an important step to ensure the quality of
installation. Once a leak is detected, proper action should be taken immediately.
INSTALL THE WATER DRAINAGE PIPE
1.
For good drainage, the drain hose should be angled downwards.
2.
Do not pull on or bend the drain hose or flood its end with water.
3.
Use inline pumps for water uplift or if the water drain pipe is very long
4.
When the long drainage hose passes through indoor areas, it should be wrapped in
insulation.
29
NOTES:
The copper pipe used in the refrigeration lines is very soft, high pressure copper and prone
to get damaged if not handled correctly. Try to avoid getting it bent or stretched. Always use
foam protectors (sleeve) and a plastic ring before getting the pipes through the wall. Those
will help prevent damage to the pipes.
To keep the allowed
bending radius please
make the packed soft
pipes vertical before
Please do not extend only one side of
the packed soft pipes.
Please make use of
semicircle pulley to keepthe
allowed bending angle
Extreme bending could damage the pipes
Please use a twisting
wheel to avoid improper
bending.
Over bent soft pipes will lead to irregular
bending
Please use rigid elbow to
keep the bending angle
while soft pipes operating.
Undersize bending will damage the soft
pipe.
Please keep the minimum
bending angle while
installing
Do not use short sharp angle bends.

CONNECTION OF ELECTRICAL POWER AND SIGNAL CABLES
Only allow qualified engineers that can follow local regulations to install the equipment
and the power.
Warning:
The air conditioner unit must be securely grounded!
If the power cord or signal cable of the appliance is damaged, it must be replaced with a
new cord with same or better specifications.
Dedicated power cable should be used on the air conditioner. Also overload protection
circuits may be used as necessary.
Ensure wiring is correctly performed and connections are tested
All wiring should be connected correctly according to the electrical wiring schematic,
incorrect wiring will cause the air conditioner to operate incorrectly or be damaged.
Never alter the wiring inside the air conditioner or perform unauthorised service.
CONNECTION OF THE POWER CORD
Supply the power to both indoor / outdoor units following the wiring diagrams in this
manual. Where discrepancies are found between the diagram within the manual, and the
circuit diagrams on the unit, the information provided on the appliance must be followed.
SIGNAL CABLE
Attention must be paid when performing wiring operations, to avoid air conditioner
malfunction due to electromagnetic interference.
(1)
The signal cable shall be separated from the power supply line and outdoor and
indoor connection line;
(2)
If the air conditioner is installed in a place susceptible to interference, it is best to use
shielded wire and twisted pair as signal cable or for the wired remote control

T4)
eiq-FC18K = 5.3kw, eiq-FC24K= 7.1kw, eiq-FC36K= 10.5kw, eiq-FC48K=14kw.
The kw is converted approximatively to hp in the pcb logic as 5.3kw= 2HP,
7.1kw= 3HP, 10.5kw= 4HP, 14kw= 5HP. If for eiq-FC18K e.g. max capacity is
measured as 3xHP=6 (A) as in code (2). The variable DC inverter operating
capacity is calculated as per table below. So if T4 is
22 ⁰C than the variable
operating capacity is 80% of 6 rounded to integer 6x80%=4.8 the display will
show 5. For the same unit if T4 is 16⁰C than the unit will display 3 (rounded up
from
2.4).
