2.Roof Mounting

(1)The figure shows the use of the roof curb available

for mounting these units.

(2)The curb should be sealed and fixed to the roof by

weather stripping. A suggested means of sealing the unit and roof curb is shown below.

Roof curb

6-ø15 Unit mounting holes

4-ø15roof mounting holes

Unit

Roof deck

Seal with tar

(1)Care must be taken to prevent recirculation of

the condenser air. To stabilize compressor condensing pressures it is recommended that wherever possible the condenser air inlet side be faced away from prevailing winds.

(2)For rooftop installation, the type of mounting

base depends on the roof construction. A builtup roof may not support the weight of the unit and so it may be necessary to support the unit by adding structural members below it.

All series of air conditioners are designed for outdoor installations and are to be placed on a slab or rooftop, however if the air conditioner is to be installed in a plant room application, please contact your equipment supplier prior to installation. Access for both service and installation must be provided to the compressors, control wiring and fans as shown below.

(3)The units are equipped with hoisting

plates for rigging and hoisting of the unit. The hoisting plates are located in the base of the unit. When hoisting the unit with a crane, spreader bars must be used to prevent damage to side panels by the supporting cables.

3.Duct Work

(1)All series units are equipped with horizontal

supply and return air openings. Duct connection to the unit should be made with duct flanges and secured directly to the air openings with flexible duct connectors to avoid normal noise transmission.

(2)For vertical air supply, a field supply plenum should

be used. The figure below shows the recommended method for duct connection.

(3)To prevent air leakage, all duct seams should be

taped. Ducts run in air spaces that are not air-conditioned must be insulated and provided with a vapor barrier. Ducts exposed to the outside must be weatherproofed. For quiet operation, we recommend that the insulation on the supply duct be placed inside, lining the duct.

(4)Where ducts from the outside enter a building, the

duct openings in the building should be sealed with weather stripping to prevent rain, duct, sand,etc. from entering the building.

(5) Correctly sized filters must be fitted and there is no

provision within the unit, however the filters may be installed in the return air.

4.Drain piping

(1)A 1 FPT condensate drain fitting is provided. The

drain pipe can be led out at the right or left side. Under standard specifications, it is led out at the left side and the right side is covered.

(2)The drain pipe must be provided with a trap on the

outside of the unit and also installed at an incline for proper drainage, as shown below.

(3)To prevent condensate formation and leakage,

provide the drain pipe with insulation to safeguard against sweating.

(4)Upon completion of the piping work, check that there

is no leakage and that the water drains off properly.

6.Final Checks

After having installed the unit, check that: (1) The unit is fixed securely. (2) The unit is installed properly. (3) The drain pipe is provided with a drain trap. (4) The electrical wiring has been connected correctly and the terminal screws have been properly

tightened.

(5) The duct work has been performed correctly.

7.Trial Operation

(1) Before turning the unit on, measure the resistance between the terminals of the electrical parts and

ground with a 500V megger and check that the value is at least 1MΩ. If the measured value is below 1MΩ, do not operate the unit.

(2) Check the operation of the high pressure switch by activating it. Operation should stop when the two leads

of the outdoor unit fan motor are removed from the contactor and cooling continues for 5~10min. (3) Check that the indoor and outdoor fans are rotating in the proper direction. (4) After having checked the above points, proceed with a trial operation of the unit.

5.Electrical Wiring

Remove the panel on the right side (PR,PRH-5 10) or the rear side (PR,PRH-15,20) of the unit and

connect the units power supply wiring to the proper terminals in the control box, as shown below.

3.MAINTENANCE

For superior performance and lasting durability, please do not forget to conduct proper and regular maintenance.

3.1 Cleaning the Air Filter

Clean the air filter about once a week with a neutral cleanser and leave it to dry in a shady location. Clean

more regularly if the air filter gets very dirty.

If the filter gets blocked, air will not be sucked in properly, and the cooling effect will deteriorate. Failure to

clean the air filter may result in equipment breakdown or malfunctions.

3.2 Cleaning panels

Clean dirt off front panel as follows.

Use a household neutral cleanser such as for dishes or vegetables. Moisten a soft cloth with the cleanser, then wipe lightly. Next,wipe three or four times with another soft cloth moisten with water. Finally, wipe off all the remaining cleanser with a soft cloth.

Moisten a soft cloth with the alcohol, then wipe off lightly. Isopropyl alcohol is sold at stores as reagents in small quantities.

3.3
