Safety Precautions
Cautions and Warnings
Read these precautions carefully before repair.
This manual classifies the precautions into Warning and Caution. Warning is very
important as failure to observe it may lead to deaths or serious injuries. Caution is also
important as in some cases failure to observe it may also lead to grave accidents. Hence,
be sure to follow the safety precautions below.
After completing repair, test the unit to ensure it runs properly. In addition, give the
user adequate instructions concerning the precautions when using this unit.
Warnings During Repair
Before dismantling the unit for repair, be sure to remove the power plug, as operating
a device that is powered on may result in electric shock. If repair must be carried out
with power on, do not touch any active part.
Keep away from the refrigerant gas that leaks during repair, because exposure to this
gas may result in frostbite.
When dismantling compressor intake or discharge pipes at welding part, first empty
refrigerant gas in a well-ventilated place, as the trapped refrigerant gas or refrigerator
oil may flow out and cause injuries.
If any refrigerant gas leaks during repair, ventilate the place immediately. Refrigerant
gas may produce a toxic gas if it comes in contact with fire.
Boost capacitor is a component that provides high voltage electricity for ODU
electrical parts. Make sure it is fully discharged before repair; otherwise, it may cause
electric shock.
Do not attempt to turn on or off the unit by inserting or removing the power plug, as
this may result in electric shock or fire.
Precautions During Repair
Do not attempt to touch electrical parts with wet hands, as it may cause electric shock.
Do not clean the air conditioner by spraying water on it, as it may cause electric
shock.
To prevent an electric shock, make sure that the unit is grounded when repair is
carried out in a damp place.
Cut off the power supply and remove the power plug before cleaning.
The fan running at high speed may hurt people.
When relocating the unit, do not tilt it; otherwise, the water inside the unit may splash
on floor and furniture.

4
Before repair, check to make sure that the refrigeration and circulation system is fully
cooled. Otherwise, it may result in burns.
Make sure to use the gas welding machine in a well-ventilated place, as use of it in a
sealed room may cause hypoxia.
Warnings after Repair
Use components listed in the Maintenance Parts List and appropriate tools of the
corresponding model. Do not attempt to modify the unit, as improper use of
components or tools may cause electric shock, overheating or fire.
When installing the unit in a new place, make sure that the place of installation is
strong enough to support the unit’s weight. If the place cannot provide enough
support or the installation is not secure enough, the unit may fall and cause injuries.
Make sure to use a standard mounting rack to install the unit. Improper use of
mounting rack or operations may result in unit dropping and personal injuries.
Fasten the unit securely to the mounting rack that is fixed on the sash frame.
Improper installations may cause unit falling and personal injuries.
When wiring, make sure to use a dedicated power supply and observe the relevant
technical standards, internal wiring rules and installation manual on electrical equipment.
Insufficient power capacity and improper electrical wiring may cause electric shock or fire.
Be sure to use dedicated cables to connect IDU and ODU. Fasten and arrange the
wires in a way that the wires at the joint are not too tight. Improper wiring may result in
overheating or fire.
When connecting IDU and ODU, make sure that the terminal cover doesn't fall off
because cables extend out of the cover. If the covers are improperly fixed, the
terminal connection part may cause electric shock, overheating or fire.
Do not damage or change power cords, as damaged or changed power cords may
result in electric shock or fire.
Do not put heavy objects on power cords. Heating or stretching power cords will
cause damages to power cords.
Use designated refrigerants (R-410A) in the refrigerating system. Do not let air or
other gases in refrigerating system, as it may generate high pressure and hence
damage the unit.
If refrigerant gas leaks, make sure to find the leaking points and repair them before
refrigerant can be added. If leaking points cannot be determined, stop repair work
immediately and perform evacuation. Close service valves to prevent refrigerant gas
from entering the room. Refrigerant gas is nontoxic in itself. However, when it comes
in contact with fire, or fans, other heaters, furnaces, it may generate toxic gases.

5
Make sure to dispose of the old batteries after removing them from the remote
controller. Keep these batteries away from children.
Precautions after Repair
Residual current device may be provided depending on circumstances to prevent
electric shock.
Do not install the unit where flammable gases are present, as it may cause fire.
Install sealing parts and pads to mounting rack correctly, as improper installations
may let water in room and wet furniture and floor.
Check after Repair
Check to make sure that power plug is clean and fastened securely, and then insert
the power plug into power socket. If power plug is dirty or loosened, electric shock or
fire may occur.
If cables and wires are scratched or damaged, make sure to replace them with new
ones, as broken cables or wires may cause electric shock, overheating or fire.
Do not use cables in tandem or stretched cables. Use a separate socket. Otherwise,
it may cause electric shock, overheating or fire.
Check whether all parts are fastened reliably, wires connected correctly and welding
part or crimping part connected securely. Improper installation or wiring may result in
electric shock, overheating or fire.
Replace the corroded mounting stand or rack with a new one, as the old ones may fall
off and cause personal injuries.
Check grounding. If the unit is grounded improperly, repair it immediately, as improper
grounding may cause electric shock.
After repair, measure insulation resistance to make sure that the value is at least
1 MΩ, as improper insulation may cause electric shock.
After repair, check IDU drainage status, as improper drainage may allow water enter
the room and wet the floor or furniture in it.

Preface
Thank you for purchasing TICA products.
This is the Maintenance Manual for TICA cooling and heating type air conditioners (TIMS).
TICA offers a broad spectrum of models to meet different air conditioning needs in
buildings and offices. We believe that there is a model for everyone.
This Maintenance Manual contains information on repairing R-410A cooling and heating
type air conditioner (TIMS).

①Compressor
Air inlet
Air jetting port
Air outlet
The inverter compressor adopts the low-
temperature and strong heating scroll compressor
that is equipped with the advanced permanent
magnet synchronous motor. Speed: 20-100RPS;
generally, compressor coil has a resistance value
of 2~4 Ωand insulation resistance ≥1 MΩ.
Features of scroll compressor:
1. Highest efficiency
2. Small rotation torque changes, stable
performance with less vibration and low noises
3. Least components used, simple structure,
compact, low weight and high reliability
4. High requirements for machining precision and
high costs

⑥Pressure sensor
The pressure sensor converts the system pressure value into voltage signal, and then
sends the signal to main board, thereby ensuring system operation and pressure
protection. Falling into two categories (low pressure and high pressure), the pressure
sensor has 3 lead-out wires.
High pressure sensor (red) Vout=0.87*Pg+0.5
Low pressure sensor (blue) Vout=2*Pg+0.5
Pg=Mpa (gage pressure)
Model High/low pressure sensor Item No.
