Safety Precautions
Caution: Read this manual carefully before installation and use of the unit. The following
standard is applied to this product
This installation manual is applied to TICA TIMS-S/ST/SA/SRYA
series R410A refrigerant inverter VRF air (cooling only) conditioning
units.
The manual is subject to change based on improvement on air
conditioners without further notice.
Preparation before
installation
● Installation shall be left to
a licensed professional.
Users shall not install,
repair or displace the air
conditioning unit by
themselves.
● Be sure to use a
dedicated power circuit.
Make sure the supply
voltage fluctuates within
10% of rated voltage.
Power supply should be
separate from welding
transformer because the
latter may cause large
voltage fluctuation.
● Get a licensed electrician
to install the unit
according to national and
local power standard, and
to check whether line
capacity meets
requirements and
whether power lines are
loose or damaged.
● "Electrical control
schematic diagram" is
attached to the back side
of cover plate of ODU
control box. Please keep
the manual properly for
further reference.
Precautions during installation
● Do not touch heat exchanger
fins. Otherwise, it may cause
damage to the fins or reduced
performance for the unit or
finger injury.
● The cover plate for control box
must be fastened to prevent
incoming of dust and water.
The electrical parts must be
water-proof and away from
water sources, otherwise
electric shock or fire may be
caused.
● After installation, be sure to
make an air tightness check
whether there is pipeline
leakage.
Precautions for using R410A
refrigerant devices
● Please supplement
refrigerating system with liquid
refrigerant. In the case of
gaseous refrigerant,
composition of refrigerant in
the system may change.
● Do not mix into other
refrigerants.
● Do not use the following tools
ever used for common
refrigerants (such as R22):
pipeline pressure test devices,
charge hoses, leakage
detection devices, refrigerant
charge base, and refrigerant
recovery devices.
● Make sure to use vacuum
pump dedicated for R410A
series.
Precautions at trial operation
● When the system is powered
on for the first time or after
being left unused for a long
time, ODU power must be
connected 24 hours before
use. Otherwise, the
compressor may be burnt
(make sure the air
conditioner is in standby
mode at the seasons they are
needed most).
● Do not turn on the air
conditioner when the panel or
protection screen is removed.
The moving parts inside the
air conditioner may hurt
people or other objects.
● Do not touch refrigerant
pipeline during operation or
just at the end of operation.
The pipeline of the air
conditioner may be very hot
or cold during its operation,
which may lead to scald or
frostbite.
● Do not turn off power
immediately after the unit
stops. Wait at least for five
minutes to prevent water
leakage.
● Please cut off general power
supply during seasons the air
conditioners are not used to
prolong the service life and
save energy.
● All the IDUs and ODUs of the
same system must be
supplied with power
simultaneously.

Installation of ODU
Installation space
Requirements for installation position
● The installation position shall have sufficient strength to bear the unit weight and its
vibration during operation. If the ODU is installed on a roof, make sure the roof is strong
enough and water-proof.
● The ODU shall be installed in a well ventilated place to ensure good heat exchange.
● Places unsuitable for installation:
▲ The place where acid or alkaline substance or corrosive gas(e.g., sulfur dioxide and
hydrogen sulfide) may be produced, easily corroding the unit and leading to
refrigerant leakage.
● Places where air conditioning units must not be installed
● ▲ The place where flammable gas or volatile combustibles may be produced. If
flammable gas leaks and accumulates around the unit, the unit may explode.
▲ Do not install the ODU where it is exposed directly to strong wind or typhoon. When
conditions permit, add auxiliary equipment to prevent water, snow or direct sunshine.
▲ Do not install the outdoor unit just below the edge of the roof, to prevent the unit
failure caused by the dropping of rubbles or ice particles. If installing the outdoor unit
in this position is unavoidable, mount a protective shed above it.
Installation of snow protection facilities
● Install snow protection facilities in the snow area, such as
the snow protection cover and shed.
● Inadequate snow protection facilities will result in a high
probability of malfunction.
● Appropriately raise the bracket stand to avoid snow
accumulation.
Requirements for ODU installation space
● Make sure there is enough space above the unit.
● The side with TICA symbol attached shall be the front side of ODU.
● Make sure that the surrounding walls are not higher than the specified value below:
front: 1500 mm, rear: 500 mm, left and right: unlimited
● Otherwise, the maintenance distances at front or rear side should be increased by H/2, as
shown in the following figure:

Handling
Notes:
● Fragile and handle with care.
● The degree of inclination shall not exceed 30° while handling (do not put the unit on
its side).
● Keep heat exchange fins safe while handling and installing the unit. In case of any
damages, please use fin comb to fix it up.
● Properly dispose of packaging bags and prevent kids from playing with them.
● Use forklift to handle: be careful when inserting the fork into the pocket at the bottom,
and prevent fork from damaging the unit or the unit bottom.
● Use crane to handle: tighten hoisting rope according to what is shown in the figure,
and keep the unit weight even during hoisting.
● Use two hoisting ropes at least 8 m long and about 20 mm in diameter to support the
unit weight. Do not use tying band of the unit for handling.
● After the wooden framework is removed: use paper or cloth as pad between hoisting
rope and the unit to prevent damages to the unit body.
Placement
● Make sure the ODU is placed firmly at a level place to prevent vibration and noises.
● Use a base larger than the width of ODU's support legs (66 mm) to support the unit.
● The shock-absorbing pads shall cover the entire bearing surface of the base.
● The unit base shall be at least 200 mm higher above the ground.
● Around the base there should be drain to ensure that the condensate water
generated during operation could flow out.

15
Installation of Refrigerant Piping
● Concrete foundation: the foundation shall be above the ground for at least 150 mm.
● Use anchor bolts, nuts and pads to fasten the ODU tightly to the base.
Caution: shock-absorbing pads need to cover the entire bottom of the unit, and the pad
thickness is greater than or equal to 20 mm.
● For anti-corrosive models: use rubber pads. If the nut joints get loose, the unit will not
be corrosion proof.

16
Installation of Refrigerant Piping
Precautions for the installation of piping:
● Use clean piping that is free from dust, moisture or any other substances.
● Store all the pipelines needed for installation indoors, and keep two ends of pipelines
sealed till welding.
● Pass copper pipes into the holes at wall and seal the holes to prevent dirt coming in.
● Do not do ODU piping work on rainy days, lest that moisture and dirt would enter the
pipelines.
● Try to reduce bended piping and use bends with larger radius.
● When connecting refrigerant piping, the stop valve of ODU shall be closed
completely after refrigerant piping between ODU and IDU is done, and refrigerant
leakage test and vacuumizing process are finished.
