Installation

For minimum clearance, consult the certified submittals, which are available on request from your Trane Agency.

Unit nameplate

The unit nameplate gives the complete model reference numbers. The unit power rating is shown, and power supplies should not deviate by more than 5 % from the rated power. Compressor motor amperage is shown in box I.MAX. The customer’s electrical installation must be able to withstand this current.

Installation instructions

Foundations

No special foundations are required, provided the supporting surface is flat and level, and can withstand the weight or the unit.

Anti-vibration rubber pads

They are supplied as standard with the machine, and should be placed between the supporting floor and the unit to attenuate vibrations.

- 4 pads for the sizes 190 to 300

- 6 pads for the sizes 350 to 800

- Trane does not allow to install spring isolators.

Clearance

Respect recommended clearance around the unit to allow maintenance operation to take place without obstruction and recommended clearance around condenser.

Caution: Unit operation is function of the air temperature. Any recycling of the air fed out by the fans will increase the air intake temperature over the condenser fins and can result in high pressure cut-out. In this case the standard operating conditions are modified. Operation of the unit may be affected by an increase in air temperature on the condenser. When the units are positioned in a windy area, avoid all the risks of aircooled recycling.

Refrigerant lines

Calculating and fixing the capacity of refrigerant lines is necessary to assure the oil return to the compressor, avoid refrigerant phase changes and limit pressure drop.

Liquid lines

Calculate capacity of liquid line, as per the following criteria.

1. Maximum load operating

conditions.

2. To avoid any evaporation risk:

- Consider the vertical risers

- Maximum pressure drop must

not exceed 1 to 2°C

3. Liquid circulation speed in a 0.5

to 2m/s range.

Discharge lines

Discharge lines should be calculated to obtain the gas displacement speed in horizontal and vertical lines required to drive compressor oil. Determine diameter of discharge lines as per the following criteria.

1. Speed above 2,5 m/s horizontally.

(Consider minimum speed at minimum load)

2. Speed above 5,0 m/s vertically

(Vertical risers, consider speed at minimum load)

3. Maximum speed 20 m/s.

4. Horizontal pipe run must be

pitched of 1cm/m in the same direction as the refrigerant circulation

5. An oil trap is necessary for

vertical risers greater than 3m. For major elevations add an intermediate oil trap every 5m.

6. Maximum pressure drop between

20 to 50 kPa

7. Install a filter drier adapted to

refrigerant capacity.

Insulation of refrigerant lines

Insulate refrigerant lines from building itself to avoid transmission to building structure of vibrations normally caused by pipework. Also avoid bypassing the unit's damping system by fixing the refrigerant lines or the electrical ducts very rigidly.Vibrations may propagate into building structure through rigidly fixed refrigerant lines.

Pressure tests. Leak detection

During operations, take the following precaution:

1. Neither oxygen nor acethylene should be used instead of refrigerant and nitrogen to detect leaks, otherwise a violent explosion may occur.

2. Always use valves and manometers to check the test pressure in system. Excessive pressure may either cause pipes to rupture, damage unit, or cause an explosion, causing possible physical injury.

Carry out liquid line and hot gas line pressure tests in accordance with current standards. The test pressures applied to the liquid line and the hot gas suction line must comply with the country's standards.

Caution: Do not go more than 0.7 bar above the high pressure switch setpoint.

Introduce enough refrigerant into circuit for 85 to 100 kPa pressure, pump-injecting dry nitrogen, and raise pressure to 100 kPa. Search for possible leaks using detector. This operation should be carried out with great care throughout the system. If leaks are detected, reduce system pressure, and repair defective component. Repeat test process, to check that the repair can withstand rated pressure.

Caution: Unit is delivered with a refrigerant holding charge and isolating valves.

Oil charge

Attention: The oil quantity necessary for the split system has also to be adjusted according to the diameter and the length of the refrigerant piping work.

Important note: These operations have to be performed by a specialist according to the rules of the art. The results have to be written on a start up record by the Trane engineer or the client's specialist who has performed this start up. The quantiy of refrigerant and oil added are at the client's charges.

Refrigerant charge (all split system types)

After system pressure and vacuum testing, fill up unit with refrigerant as per indicated in table Refrigerant Charge. The refrigerant complement will be charged according to the diameter and the length of the refrigerant piping work up to obtain the correct superheat and subcooling temperatures.

Electrical connections

Caution

1. The greatest care should be taken when cutting through passages and installing electric wiring. Under no circumstances should chips of metal or cuttings of copper or isolating material fall into the starter panel or electric components. Relays, contactors, terminals and control wiring should be covered and protected before power supplies are connected.

2. Install power supply cabling as shown in wiring diagram. Adequate cable gland should be chosen, ensuring no foreign bodies enter the electrical housing or components.

Caution

1. Cabling must comply with standards in force. The type and location of fuses must also comply with standards. As a safety measure, fuses should be visibly installed, close to the unit.

2. Only copper wiring should be used. Using aluminium wires can produce galvanic corrosion and possibly lead to superheat and failure of connection points.

As an option, Trane provides the unique power supply which includes the transformer. If the transformer is not ordered, it is necessary to foresee the power supply of the electronic module separately. Warranty reserves will be formulated if a transformer, not supplied by Trane, is installed inside the electric panel

One temperature sensors per circuit is provided as an accessory, in control panel of unit. They have to be fitted in order to measure the air outlet temperature downstream to the DX coil (evaporator). The SMM control module has to be set up according to the above temperature. Refer to supplied wiring diagram for connection of sensors

Note: If the sensor cables are too short, an extension-screened cable type will be connected as close as possible to the sensor (50 cm max.). This extension must be soldered and isolated with thermo-retractable cable sheathing. Do not install or cross the sensor cables with the power cable in order to avoid electrical disturbance and affect the operation of the SMM control module.

Operating parameters statement:

- Switch on main power supply switch.

- Start-up the unit pushing button ”I” of control module. The green LED must be lit, the SMM control module must be in”cooling mode”.

- After unit start up, leave in operation for at least 15 minutes, to insure pressures are stabilized.

Then check:

- voltage.

- compressors and fan-motors currents.

- suction temperature and pressure.

- ambient air temperature.

- blowing air temperature.

- discharge pressure and temperature.

- liquid refrigerant temperature and pressure.

- operating parameters:

- superheat: difference between suction temperature and dew point temperature. Normal superheat must be within 5°C and 10°C.

- sub-cooling: difference between liquid temperature and bubble point temperature. Normal subcooling on standard unit with R22 or 134a should be 5 to 10°C, and 2 to 5°C with 407c.

- difference between dew point temperature in high pressure and condenser air inlet temperature. Normal value on standard unit with R22 or 134a and all the fans operating should be 15 to 18°C. With 407c, it should be 20 to 23°C.

Final check:

When the unit is operating correctly:

- Check that the unit is clean and clear of any debris, tools, etc…

- All valves are in operating position.

- Close control and starter panel doors and check panels fixation.

Caution

- For the warranty to apply, any start-up carried out directly by the customer must be recorded in a detailed report, which must be sent as soon as possible to the nearest Trane office.

- Do not start-up a motor whose insulation resistance is less than 2 meghoms.

- Phase imbalance should not be greater than 2%.

- The voltage supplied to motors should be within 5% of the rated voltage on the compressor nameplate.

- Excessive emulsion of the oil in the compressor shows that refrigerant is present in the oil and the result will be that compressor is not lubricated enough. Shut down compressor and consult Trane technician.

- Excess oil in compressor can damage the compressor. Before adding oil, consult Trane technician. Use only Trane products recommended.

- The compressors must operate in a single direction of rotation. If refrigerant high pressure remains stable in the 30 seconds after compressor start-up, immediately shut down unit and check the direction of rotation using phasemeter.

Caution

- Please refer to specific Trane documentation on oil, available from your nearest Trane office. Oils recommended by Trane have been exhaustively tested in Trane laboratories to the specific requirement of Trane chiller and hence the user’s requirements. Any use of oils not meeting specifications recommended by Trane is the responsibility of the user only, who thereby is liable to warranty loss.

- Oil analysis and oil test acidity must be carried out by a qualified technician. Poor interpretation of results may cause unit operating problems. Also, oil analysis must follow the correct procedures, to avoid accidental injury to maintenance personnel.

- If the condensers are dirty, clean them with a brush. If the coils are too dirty, consult a cleaning professional. Never use water to clean condenser coils.

- Contact Trane ServiceFirst for information on maintenance contracts.

Warning

- Switch off unit main power supply before to any intervention. Failure to follow this safety instruction can lead to accident death of the maintenance personnel and may also destroy equipment.

- Never use steam or hot water above 55°C to clean condenser coils. The resulting increasing pressure could cause refrigerant loss through the safety valve.
