ENERGY SAVING AND UNIT SAFETY PROTECTION TIPS



Do not cover or restrict the airflow from the outlet or inlet grills.



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 mode when the ambient indoor
temperature is higher than 35℃.



To protect the unit we recommend not using the heating mode when the indoor ambient
temperature is lower than 7℃. Performance will be reduced at lower temperatures.



Note the manufacturer operating temperature ranges at the end of this user manual.

HOW AIR 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.

1. Evaporator

2. Filter

3. Evaporator Fan

4. Gas Line

5. Liquid line

6. Compressor

7. Condenser

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.

INSTALLATION OF THE OUTDOOR UNIT

In order to ensure the correct working of the air conditioner, in the choice of installation
location, the following guidelines must be followed:

1.

Upon installation of the outdoor unit, the air discharged outdoors should not return, and
enough space for maintenance must be left around the machine.

2.

The ventilation must be excellent in mounting points, so that the machine can intake and
discharge sufficient air. Make sure there are no obstacles for air inlet and outlet; any

obstacles should be removed.

3.

The installation location is strong enough to withstand the weight of the outdoor unit, and
has the effect of sound insulation and vibration reduction. And to ensure that outlet air

and noise of the unit will not affect the neighbours.

4.

Avoid direct sunlight, it's best to put up an sunshade for protection.

5.

In the mounting position, rain and condensate water must be drained.

6.

In the installation position, it must be ensured that the machine will not be buried in the
snow, and not subject to the effects from garbage and mists.

7.

In the installation position, it must be ensured that the air outlet is not facing the strong
wind.

MOUNTING ON A ROOF OR OTHER WINDY POSITIONS

When the outdoor unit is to be mounted on the roof or place around which there is no building, it
is necessary to avoid strong winds directly blowing into the air outlet of the outdoor unit. To avoid
impairing the heating or cooling effect and failure of the outdoor unit heat exchanger due to
inadequate air flow.

A. When there is wall nearby, please locate the air exhaust facing the wall and keep about

500mm distance from the wall.

B. When the air exhaust is affected by strong wind or wind direction, it is necessary to

change the air intake unit position to make the exhaust port perpendicular to the wind
direction.

CONDENSATE DRAINAGE OF THE OUTDOOR UNIT

When operating in heating mode condensate
will collect and drain through the base of the
outdoor unit. The air conditioner is supplied with
an elbow joint which can be connected to the
underside of the outdoor unit for drainage.

1. Connect the elbow joint to the drainage hole
on the underside of the outdoor unit.

2. Connect a drain hose (not supplied) to the
elbow joint and run downhill to your chosen
drainage point.

Please note: The drainage is gravity fed, and so
must run downhill.

30

REFRIGERANT PIPE INSTALLATION

Note:

1.

Refrigerant pipe is not supplied with the unit, but a selection are available from the same
retailer as the air conditioner.

2.

A thermal insulation sleeve of more than 9mm thick and with favourable thermal
insulation performance should be used to avoid condensation when selecting the

NOTES:

The copper pipe used in the refrigeration lines are very soft, high pressure copper and prone to
get damaged if not handled correctly. Try to avoid bending or stretching the pipework. Always
ensure the pipes are protected when running through the wall to help prevent damage to the
pipes.

To keep the allowed
bending radius please
make the packed soft
pipes vertical before
extending

Please do not extend only
one side of the packed soft
pipes.

Please make use of
semicircle pulley to keep the
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.

33

STANDARD 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 following torque table).
Excessive torque action might damage the joints while too little torque might lead to leakage.

Torque based upon the wrench to be used

Follow the procedures below:

1. Remove the dust caps from the indoor and outdoor units and the connecting pipe.

2. Align the joint of the connecting pipe between the indoor and outdoor and tighten the

connecting nut by hand to prevent cross threading. Secure them with a wrench, applying
the maximum torque as shown in the table above.

3. Pressure test and vacuum pump the pipework for each refrigerant circuit.

4. Remove the two valve core caps from the outdoor unit and turn on the high and low

pressure valve cores with an socket wrench, then tighten the two valve core caps of the
outdoor unit. Finally you can wrap hot insulating tape around the joints of indoor and
outdoor units

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 low­pressure side of the 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 low pressure
valve on 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 2­way and 3-ways valves, applying
the torque listed in the table
above.

35

PRESSURE TEST, VACUUMING AND LEAK TEST OF CONNECTING PIPE AND
INDOOR UNIT PIPELINE:

After installed the connecting pipe and indoor unit, firstly charge the nitrogen into the
connecting pipe and indoor unit pipe to 3.0Mpa and keep the pressure for 24h; at
same time, check for leaks with soap bubble at the connectors and welding
positions; if no leak detected, discharge the nitrogen and vacuum with a
vacuum pump (the vacuum degree shall be less than 30Pa), and then open the
main machine valve for a test run ; if the refrigerant pipe length is more than 5m,
refill the refrigerant and refer to following table:

eiQ-CRFC18K

eiQ-SSRFC24K

eiQ-SSRFC36K

eiQ-SSRFC48K

eiQ-SSRFC60K

added per metre of
liquid pipework above
5m.

0.012Kg

0.024Kg

0.024Kg

0.024Kg

0.024Kg

i.e. If liquid pipe on an eiQ-SSRFC24K is 7m, amount of refrigerant to be added would be (7 –

5)*0.024Kg, so 0.048kg should be added.

When refilling the refrigerant, use the needle valve on low pressure valve body of
outdoor unit in refrigeration mode.

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.

36
