DIAGNO TIKA_EN
Unit pre-loaded of gas R134a with high precision machine.
A- by manipulating the load of the unit leaves it out of warranty!
B- The harge fittings of the (R) unit are autosealed.lf these are manipulated,
THE WARRANTY is automati ally lost!
C- The onne tion to the battery or any authorised point set in the mounting
instru tions is absolutely ompulsory !
In ase of not doing so, the battery ontrol is lost and the ele troni s will

30A power supply cable)
Electronic control defective
Power cable disconnected, with poor
contact or cut
Electronic control power fuse (15A)
disconnected or blown
A
If the unit does not come on or the
display and the unit go off during
Power cable polarity inverted
Poor connection in return air sensor
cables or terminals
B
When the unit starts up or runs,
the display switches E0 and ca
(return air sensor failure). The unit
works during this error, but
without return air sensor regulation
(and the temperature cannot be
changed). Press the ON/OFF
button on the keypad or remote
control once to turn off.
Return air sensor disconnected or
faulty
Poor connection in anti-freeze sensor
cables or terminals
C
The display shows E6 flashing Anti-freeze sensor disconnected or
faulty
Poor contact in power terminals or
connections
D
When the unit starts up or runs, it
gives out a beeping sound followed
by the display showing (low
battery). The unit shuts down
automatically.
Battery discharged or defective
Centrifugal blower or condenser fan
blocked in short-circuit or
disconnected
7.5A fuse of the centrifugal blower or
the condenser fan blown
E
The display shows E2 and the unit
goes off automatically, with the
display continuing to show error E2
until the anomaly is repaired. To
remove from the display, press the
ON/OFF key once on the keypad
or remote control Electronic control defective
Poor terminal connection
Compressor electronic module
deffective
Compressor failed
F
A compressor does not work
A lot of pressure in the circuit due to
excess load or very high temperature
Remote control not programmed
Remote control battery flat, the LED
does not come on
Electronic control faulty
G
The unit does not respond to the
remote control
Remote control defective

5_DIAGNO TIKA_EN
H
The unit gives out a beeping sound
Control panel and electronic control
connection cable poorly connected or
inverted in electronic control or control
panel
I
When the unit starts up or runs,
the display shows E9 (compressor
protection). The unit goes off
automatically, with the display
showing E9 until the unit has
a slant of less than 45°
Unit slant 45° or over
Valves or wastewater pipes obstructed
EPDM seal poorly attached or defective
J
Water is entering the cabin or is
filtering in from outside The cable outputs which protrude from
the inside cover of the evaporator
cabin and the centrifugal blower are
not properly sealed
Too much or too little load in the
circuit
Condenser fan terminal inverted
Dirt in the capacitor
Condenser fan defective
K
The equipment works but does not
cool
Blockage in the circuit

SOLUTION
Connect or replace the power cable fuse
Replace the electronic control
Check and correct any possible poor contacts, splits or disconnections of the
power cable
Connect or replace the electronic control power fuse (first take down the
interior air distribution panel)
A
Check and correct the position of the power cables (az with 30A fuse to +
and M to -)
(if the error persists, contact the Authorised Technical ervice)
Check and correct any possible poor contacts in cables or terminals of the
return air sensor
B
Connect or replace the return air sensor
(if the error persists, contact the Authorised Technical ervice)
Check and correct any possible poor contacts in cables or terminals of the
antifreeze sensor
C
Connect or replace the anti-freeze sensor
(if the error persists, contact the Authorised Technical ervice)
Check and correct any possible poor contacts in connections or terminals of
the power cable
D
Charge or replace the battery
(if the error persists, contact the Authorised Technical ervice)
Repair the possible obstruction of the centrifugal blower or the condenser
fan; if the error persists, replace the centrifugal blower or the condenser fan
(remove the outside cover of the unit order to access the blower or the
electro; for the centrifugal blower, also remove the evaporator cover)
Replace the 7.5A fuse. To access the condenser fan or centrifugal blower
fuses, it is necessary to take down the interior air distribution panel
E
Replace the electronic control
(if the error persists, contact the Authorised Technical ervice)
Correctly connect the terminal of the compressor’s electronic module. (see
attached wiring diagram)
Replace the compressor’s electronic module
Replace the compressor
F
Check the pressure (the compressors disconnect as of 6 bars); if necessary,
recover gas and load 520g again in the circuit
To access the compresors, modules or load points it is necessary to take
down the unit’s outside cover
(if the error persists, contact the Authorised Technical ervice)
Reprogramme the remote control
Replace the remote control’s battery and reprogramme
Replace electronic control
G
Replace the remote control
(if the error persists, contact the Authorised Technical ervice)

H
Take down the interior air distribution panel and correctly connect the
electronic control and control panel connection cable
I
Position the unit with a slant of less than 45° (the unit should not work with
a slant of 45° or over as it may result in damage in the compressor). The
electronic control detects the slant, meating it must also be less than 45°
Clear the valve and watewater pipe obstruction (Remove the outer cover of
the unit for access)
Replace the EPDM seal (take down the unit and throughly clean the surface
where the EPDM seal is to be attached)
J
eal the wire output in the blower and evaporator cabin cover (Remove the
unit’s outside cover for access)
Verify the load by checking the pressure; if it is below 0.5bars or above
5.0bars with the unit running, recover the load in the faulty circuit and
empty for at least 30minutes, then introduce 520g.*
Check and correct the condenser fan cable clamp connection.
Clean the capacitor with pressurised air
Replace the condenser fan.
K
Check the pressure; if it is below 0.5bars with the unit running, clean the
faulty circuit or replace obstructed components (possibly the continuous
flow capillary tube, as this is the component with least diameter).
* Gas recovery must be precise, since part of the gas remains in the tubes of the pressure gauges.
IMPORTANT WARNING !
Take care not to invert polarities when connecting the unit to the power supply. If this
were to happen, the unit will not work and irreparable damage will be caused to the
compressor modules.
