WARNING

a) Check the assembly and component weights to be sure that the rigging equipment can handle them safely.

b) Check for adequate ventilation so that fumes will not migrate through ductwork to occupy space when welding or cutting inside air handling unit.

c) Do not remove access panel or door until fan is completely stopped.

d) Do not work on dampers until their operators are disconnected.

e) Be sure that the fan motors are properly grounded before working on them.

f) Never enter an enclosed fan cabinet or reach into the unit while the fan is running.

g) Disconnect power to the fan motor (Lock open and tag) before working on the fan.

h) Disconnect power to electric heaters (Lock open and tag) before working on or near heaters.

i) Never pressurise equipment in excess of specified test pressure.

j) Protect adjacent flammable material when welding or flame cutting. Use sheet metal or asbestos cloth to contain sparks. Have a fire extinguisher at hand and ready for immediate use.

2.0 PRE-INSTALLATION

2.1 Check items received against packing list. Notify Carrier of any discrepancies.
2.2 Examine for damage incurred during shipment. File claim with transit company if any damage is found.
2.3 Refer to rigging details as shown in (Fig.1) to transfer unit from truck to storage site.
2.4 If unit is to be stored for more than 2 weeks prior to installation, please exercise the following precautions :-
a) Choose a dry storage site that is reasonably level and sturdy to prevent undue stress and damage to the unit structure or components. Do not store on vibrating surface - damage to stationary bearing can occur.
b) Remove all fasteners and other small parts - tag and store these items in a safe place until needed.
c) Unit are shipped from the factory wrapped in protective plastic sheet. The plastic sheets may be damaged during transit or after inspection. Cover entire unit with tarpaulin or plastic coverall. Extend cover under unit if stored on ground. Secure cover with adequate tie downs.
d) When unit is stored over an extended period we recommend a monthly procedure as follows -: Remove the tarpaulin from the unit, enter fan through access door or fan section inlet, remove the belt ties (if any) and rotate fan and motor (if any) slowly by hand. This helps to re-distribute bearing grease and to prevent bearing corrosion.

7.0 FAN MOTOR & DRIVES

The 39G unit will be supplied with or without the fan motor and drive from the factory. In either case, a motor base will be supplied installed on the fan and motor base channel.

7.1 Factory Installed Fan Motor & Drive

All motors and pulleys are mounted with only a "rough" alignment. The installer is responsible for the final alignment as described in the procedure.

Fig. 10 Sheave Alignment

7.2 Field Supplied Fan Motor & Drive

Ensure that the motor is of the correct HP/kW frame size & electrical characteristics.

7.3 Installation of Pulleys

Install the pulley on the fan shaft and motor shaft for minimum overhang. Exercise care when mounting the pulley to the fan shaft. Excessive force may result in bearing damage. Remove rust preventing coating or grease from the shaft. Make sure that the shaft is clean and free of burrs. Lubricate the bore of the pulley before installing. Ensure that the fan and motor shafts are parallel and level. Use straight edge or a piece of string to check the

alignment of fixed pitch pulleys. If the pulleys are properly lined up, the string will touch them at the point indicated by the arrows (Refer Fig 10). For variable pitch pulleys, use a block of wood or other material to compensate for the difference in pulley width. To check the alignment of these pulleys, make sure that the centre lines of both pulleys are in line and parallel to the ("H" frame) bearing support channel. The variable pitch pulley is normally installed on the motor shaft.

7.4 Proper Belt Tension

(i) Correct tension of a V-Belt drive is carried out as follows:
(a) Fix the belts into the grooves and increase the centre distance until the belts are snug. Note: Never lever belts over sheaves.
(b) Operate the drive for a few minutes and observe the "bow" in the slack side. Tighten until only a slight "bow" appears in the slack side of the belts while they are in operation under load.
(c) During normal operation a V-Belt will seat itself in sheaves grooves and will require periodical check to maintain tension. The seating occurs more rapidly during the first 24 hours of operation, and it is very important to check drive tension carefully during this period and to retention as required.

(ii) For drives where tension may be critical factor, the following procedure is recommended:
(a) Using the diagram shown below, measure the span length of the drive.
(b) At the centre of the span, apply a force K (perpendicular to the span) large enough to deflect the belt 15mm per 1 meter of span.
(c) The deflection force for any V-belt should be within the minimum and maximum force shown in the table. When the tension drops to the minimum value, readjust to the maximum value.

8.0 REFRIGERANT PIPING, DIRECT EXPANSION COILS

Direct expansion coils are split into 2, 4 or 8 splits depending upon the unit size and coil circuiting. Each split requires its own distributor nozzle, expansion valve and suction piping. Suction connections are on the entering side connections for each coil split are on the air leaving side in the same order from to bottom. Refer to example on (Fig. 11).

CAUTION

Direct expansion coils are shipped pressurized with dry air. Release pressure from each coil split through valves in protective caps before removing caps. Do not leave piping open to the atmosphere unnecessarily. Water and water vapor are detrimental to the refrigerant system. Until the piping is complete, recap the system and charge with nitrogen at the end of each work-day. Clean all piping connections before soldering joints. The lower split of face split coils should be first on, last off. Row split coils utilize special intertwined circuits: either splits of these row split coils can be first on, last off.

Fig. 11 Example Of Direct-Expansion Coil Distributor And Suction Connections

8.1 Suction Piping

Connect suction piping as shown in (Fig.12) for face split coil or (Fig 13) for row split coil. Suction line from coil connection to end of the 15-diameter-long riser should be same tube size as coil connection to ensure proper refrigerant velocity. Refer to Carrier System Design Manual, Part 3, and size remaining suction line header pressure drop equivalent to approximately 2.5°F. Refer to Fig 15 for piping risers to the compressor.

To minimize the possibility of flooded starts and compressor damage during prolonged shutdown, install an accumulator in the suction line or a solenoid in the liquid line of last-on, first-off split in row applications.

Fig. 12 Face Split Coil Suction Line Piping

Fig. 13 Row Split Coil Suction Line Piping

8.2 Expansion Valve Piping

Distributor nozzles and thermostatic expansion valves are factory or field supplied.

Note:-

Factory supplied distributor nozzle sizes are marked on coil cover label. Be sure that correct nozzle is installed in each distributor before installing expansion valve.

9.0 GUIDE TO STARTING UP

9.1 Ensure that all construction debris are removed from the interior of the unit.
9.2 Install filter media in all filter section. When roll filter are used, ensure that the filter media is correctly installed and that the roll filter mechanism is functioning property.
9.3 Check that the fan, motor bearing and linkages are adequately lubricated.

a) Bearings are normally shipped full of grease for corrosion protection and may run warm temporarily on start up until excess grease has been discharged.

9.4 Hand operate all linkages, such as variable inlet guide vanes and dampers to check for freedom of movement.
9.5 Check tightness of bearing set screws or locking collars.
9.6 Check tightness of set screws on blower wheel hub and pulley.
9.7 Double check the alignment and tension of the V-belts.

9.8 VERY IMPORTANT

Before energising any power to the unit, double check that all restraints that might have been used during shipping are removed from the fan shaft. The fan shaft and motor shaft must both be free-wheeling before the power is turned on. Remove all holding down bracket used to prevent the fan and motor base moving during transit.

9.9 Check the fan speed with a strobe type tachometer, or use an approximation technique with the following formula. Obtain the motor RPM from the fan motor plate. Measure the fan and motor pulley outer diameter (OD).

$$ \text { Fan RPM } = \text { Motor RPM } \times \frac {\text { Motor Pulley OD }}{\text { Fan Pulley OD }} $$

$$ e g. \text { Nameplate Motor RPM } = 1 5 0 0 $$

$$ \text { Motor Pulley OD } = 2 0 0 \mathrm{mm} $$

$$ \text { Fan Pulley OD } = 3 0 0 \mathrm{mm} $$

$$ \text { Fan RPM } = 1 5 0 0 \times \frac {2 0 0}{3 0 0} = 1 0 0 0 $$

Check that this fan RPM measured or calculated is approximately equal to the speed shown on the sticker. If the fan RPM measured or calculated, exceeds the value shown on the sticker by much, re-balancing of the fan in the field may be required.

In doubt, please refer to your nearest Carrier representatives.

9.10 Check the direction of rotation arrow label on the drive side of the fan housing indicates the correct direction of rotation. (Refer Fig 17)

*HH - Height Horizontal
**HV - Height Vertical

1) External AHU Length = (Section Length + K) mm

where, K = 50mm (for 25mm casing thickness)

K = 100mm (for 50mm casing thickness)

2) External AHU Width = (Unit Width + K) mm

3) For Horizontal Unit, External AHU Height = (HH + K + 100*) mm

For Vertical Unit, External AHU Height = (HV + 2K + 100*) mm

*100mm is for unit base

4) If the External AHU Length is >1900mm, section will be split into several casing for shipping purposes.
