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
Snow protection cover at the air outlet
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.

Lifting hole (two at the front and two at the back) Keep the ropes t hrough
the holes t o ensure stabilit y during hoisting. Forklift pocket
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.

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.

Precautions when breaking through the knockout
Do not damage the unit shell when trying to break through the knockout.
Smooth the burrs around the hole and apply anti-rust paint after opening the
knockout with a mallet or other tools.
When passing the wire through knockout, put grommet in the hole or wrap wires
with adhesive tape for protection.

Air Tightness Test, Vacuuming and Supplementing Refrigerant
For TIMS units, vacuum pump, pressure gauge, compound pressure gauge and
charging hose used for R410A refrigerant are different from those used for R22
refrigerant. Make sure to use R410A dedicated tools.
Air tightness test
Notes:
After piping work is completed, make sure to do air tightness test for IDU and
piping.
Do not use flammable gas or air (oxygen) as pressurized gas, otherwise fire or
explosion may be caused; use nitrogen only.

Steps:
(1) Use a vacuum pump to discharge air out of the system from the spool of
liquid-side check valve. Hold gauge pressure at -1 kgf/cm2 for one hour. If
pressure increases, the system may contain water or leak; otherwise, perform
the next step.
(2) Close the vacuum pump and increase pressure by 0.3 MPa from the spool of
air-/liquid-side check valve and hold it for three minutes. Check whether
there are major leakage points.
(3) Continue to increase pressure to 1.5 MPa for three minutes, and check
whether there are minor leakage points.
(4) Continue to increase pressure to 4 MPa for 24 hours (consider the impact
from the ambient temperature), and check whether are micro leakage points.
Vacuumizing:
Use the vacuum pump with over 4 L/S gas displacement The vacuum pump ensures
the vacuum degree of the system below 755 mmHg.
Use the vacuum pump equipped with an electronic single way valve to prevent
lubricating oil from entering the refrigerant system against the current.
Vacuumize the gas pipe and liquid pipe at the same time. Before
Notes:
Use nitrogen in air tightness test instead of oxygen, flammable and toxic gas,
or water.
Use a pressure gauge dedicated for R410A with a range above than 4.5 MPa.
Connect high pressure pipe and low pressure pipe and increase pressure for
them at the same time without connecting to ODU.
After passing the air tightness test, the unit is required to lower the levels
of pressure to 0.2 to 0.3 MPa and be stored at a fixed pressure.

vacuumizing, verify that gas and liquid side check valves of ODU are closed.
Use tools dedicated to R410A, such as pressure gauges and filling pipes.
27
Air Tightness Test, Vacuuming and Supplementing Refrigerant
Supplementing refrigerant
Principles:
Before delivery, the ODUs have been charged with a certain amount of
refrigerant, but which cannot meet the needs of extended pipes. So refrigerant
has to be added according to the actual length of refrigerant piping at
installation site.
Steps:
Close compound pressure gauge, replace vacuum pump with charge tank connected
with charging pipe. Make sure the air is drained completely, and connect the
joints of charge tanks and put the tank mouth down on the platform scale.
Set the quantity to be filled at the electronic scale, and successively open
the valve of charge tank and valve of compound pressure gauge to fill the
system with refrigerant. When reaching the limits, immediately close valve of
charge tank and disconnect connection pipes.
Notes:
For refrigerant tank with siphon: the tank needs not to be put upside down
because the siphon can reach the tank bottom.
If using R410A charge tank without siphon, make sure the tank is put upside
down in the charge process, which is shown as below:

Supplemented refrigerant amount = Liquid pipe length at various diameters x
Supplemented refrigerant amount per meter
Notes:
1. For single modular units, the maximum refrigerant amount (unit + total
supplemented amount) should not be greater than 52 kg. Otherwise, the units
fail to run reliably.
2. For multi-modular units, when the calculated added refrigerant is over 40
kg, the actually added refrigerant volume should be the 80% of the calculated
value or 40 kg (whichever is greater).
For example, if the calculated value of the additional refrigerant volume is
45 kg, 45 x 0.8 = 36 kg, and the actually added refrigerant volume is 40 kg.
If the calculated amount of the supplemented refrigerant is 60 kg and 60 x 0.8
= 48 kg, the actually refrigerant amount is 48 kg.

Electric Control Installation
Wiring cautions
Cautions for power wiring
Use copper wire as power wire and do not make it too tight.
The IDU and ODU use different circuits: the ODU uses a three-phase power
supply, while the IDU uses a single-phase power supply
All the IDUs and ODUs of the same system must be supplied with power
simultaneously.
The distribution box shall be provided with a set of electric leakage
protection device and air switch for each module.
Make sure all the earth lines of the unit are connected to ground securely. Do
not connect earth lines to lightning devices, telephone line, gas pipe or tap
water pipe. Improper grounding may cause electrical shock or fire.
Cautions communication line wiring
TIMS independent/strong heat independent inverter VRF air conditioning unit
has both high voltage (power) line and control (communications) line. Do not
connect power line to the connecting terminal of communication cables!
The total length of communication line is less than 1000 m.
The shielding layer of communication line must be connected to earth lines of
each module and IDUs securely.
Conductor Insulator
Shielding layer
Sl eev e
Legends of shielded twisted pair
Communication cable is well connected before being powered on. Do not remove
the power plug with power on, lest the communication chips would be damaged.
To prevent high voltage signal from disturbing control signal, shielded
twisted pair must be used.
Try to select shielded twisted pair with dense shielding layers and smaller
lay.
Control signal has two polarities A and B, and different polarities cannot be
connected, otherwise communication failures may be caused;
As shown in the following figure:
When power line is parallel with communication line, they shall be covered by
respective conduits and kept at some distance away.

Wiring specifications
Notes:
As wires need to be bent during installation process, it is recommended to use
flexible wires, otherwise installation may fail.
The parameters in the table below are corresponding to multiple strands of
flexible copper wires. If other wires are selected, please refer to
electrician’s manual based on wiring current provided in the table.
For safety purpose, do not carry out wiring work based on rated current, for
the operating conditions may be varied with seasons.

Trial Operation
Before trial operation Make sure to check: Installation Whether the air
conditioning unit can be securely fixed at the site. Whether the place is well
ventilated and large enough for maintenance. Whether the number of IDUs
connected to ODU is allowable. Wiring Whether the insulation for the loop of
main power supply is intact. Check insulation status against national
regulations. Whether power cord and communication cable have allowable length.
Whether communication cable and power cord are connected correctly and
fastened securely. Piping Whether refrigerant piping is dimensionally correct.
Whether refrigerant piping is correctly connected and has reasonable length.
Whether refrigerant piping and drainage pipe are insulated correctly. Code
Whether the codes for capacity of control panel for IDU and ODU, and for
addresses are correct and set with corresponding numbers (S1, S2 and S3…).
Trial operation Open all the stop valves completely; Connect the power supply:
Step 1: For initial power-on, connect the IDU and ODU power supply to display CPHT (the compressor is warmed up). Start the next operation 30 min later.
Step 2: Power off all the wired and remote controllers of the IDU.
Step 3: Set the Qty. of IDUs on the outdoor electric control board. Press K2 and K3 simultaneously to log in the IDU address.
Communication check: Observe whether communication indicator light of the ODU flashes regularly. The 4-digit eight-segment digital display shows the clock. If the digital display shows malfunction, please check whether IDU and ODU circuit board codes are right and communication line is correctly connected.
