1. The following should be always observed for safety

• Please report to or take consent by the supply authority before connecting to the system.

• Be sure to read "THE FOLLOWING SHOULD BE ALWAYS OBSERVED FOR SAFETY" before

installing the air conditioner.

• Be sure to observe the cautions specified here as they include important items related to safety.

• The indications and meanings are as follows.

• After reading this manual, be sure to keep it together with the owner's manual in a handy place .

Could lead to death, serious injury, etc.

Do not install it yourself (customer).

Perform the installationsecurely referring to the installation manual.

Install the unitsecurely in a place which canbear the weight of theunit.

Perform electrical workaccording to the installation manual and besure to use an exclusive circuit.

Attach the electricalpart cover and service panel to the unit securely.

Be sure touse the part provided or specifiedparts for the installation work.

Check that the refrigerant gas do not leak after installation is completed.

Bodily injury can result from high voltage electrical components or fast moving fan drives. For protection from these inherent hazards during installation and servicing, the electrical supply must be disconnected. If operating checks must be performed with the unit operating, it is the technician's responsibility to recognize these hazards and proceed safely.

UNIT CONTAINS ANHCFC (R-22) REFRIGERANT Section 608 paragraphC of the 1990 Clean AirAct states: Effective July 1,1992 it shall be unlawful forany person, in the course of maintaining,servicing, repairing or disposing of anair conditioning system, toknowingly vent or release any CFCor HCFC refrigerant minimalreleases (air purges of refrigerant hoses) associated withgood faith attempts to recapture or recycle are exemptedfrom the ban on venting.

Use the specifiedwires to connect the unit andthe field installed cutoff switch box securely and attach the wires firmlyto the terminal so the stressof the wires is notapplied to the sections.

• Incomplete installation could cause injury due to fire, electric shock or leakageof water. Consultthe dealer fromwhom you purchased the unitor special installer.

• Incomplete installationcould cause a personal injury due to fire, electric shock,noisy operation or distortion.

• When installedin an insufficient strong place, noisy operation and distortion couldoccur.

• Incomplete connectingand fixing could cause fire.

• If thecapacity of the power circuit is insufficient or there is incomplete

electrical work, itcould result in a fire or an electric shock.

• Theuse of defective parts could cause aninjury or leakage of water due to a fire, electricshock etc.

• Ifthe electrical part cover panel are notattached securely, it could resultin a fire orelectric shock due todust, water etc.

Could lead to serious injury in particular environments when operated incorrectly.

WARNING

CAUTION

Having perfect vacuum process in the factory, our units don't have drier but have filter in the refrigerantcircuit.IncaseofrechargingR-22gasinthefield,

"DRIER" must be installed on the liquid line which is connected

from discharge part of condenser to intake part of evaporator. Because the refrigerant circuit is capable of containing water with imperfect vacuum.

The equipment does not contain surge protection. To prevent damage caused by surge, transients appropriate measures should be taken.

CAUTION

3-1. Inspection

1) Check for damage after unit is unloaded. Report promptly, to the carrier, any damage found to unit. Do not drop unit.

2) Check the unit nameplate to determine if the unit voltage is correct for the application. Determine if adequate electrical power is available. Refer to the application specifications.

3) Check to be sure the refrigerant charge has been retained during shipment. Access to 1/4" flare pressure taps may be gained by removing compressor compartment access panel.

3-2. Location and Recommendations

1) Unit Support

If unit is to be roof mounted check building codes for weight distribution requirements.

2) Location and Clearances

Installation of unit should conform to local building codes and the National Electrical Code. Select a location that will permit unobstructed airflow into the condenser coil and away from the fan

discharge and permit unobstructed service access into the compressor compartment. Suggested airflow clearances and service clearances are given in Figure 1.

3) Placing and Rigging

Rig the unit using either belt or cable slings. The sling eyelet must be placed through the lifting holes in the base rail of the unit. The point where the slings meet the lifting eyelet should be at least 6 feet above the unit. Use spreader bars to prevent excessive pressure on the top of the unit during lifting.

Important: The use of "spreader bars" is required when hoisting the unit (prevents damage to

sides and top). Top crating can be used as spreader bars.

4) Roof Mounted Units

Downflow units(only 5RT) should be mounted on a roof curb when possible. On new roofs, the curb should be welded directly to the roof deck. For existing construction, nailers must be installed under the curb if welding is not possible. Be sure attach the downflow ductwork to the curb before setting unit in place.

When installing the unit, it must be level to insure proper condensate flow from the unit drain pan.

5) Slab Mount

"For ground level installation, the unit base should be adequately supported and hold the unit near level. The installation must meet the guidelines set forth in local codes."

ENGLISH

1. Attaching Downflow Ductwork to The Roof Curb (below 5.0RT)

Supply and return air flanges are provided on the roof curb for easy duct installation. All duct work must be run and attached to the curb before the unit is set into place.

2. Ductwork construction guidelines

Connections to the unit should be made with three-inch canvas connectors to minimize noise and vibration transmission.

Elbows with turning vanes or splitters are recommended to minimize air noise and resistance. The first elbow in the ductwork leaving the unit should be no closer than three times blower diameter to

avoid turbulence and back pressure.

3. Attaching Horizontal Ductwork to the Unit

All conditioned air ductwork should be insulated to minimize heating and cooling duct losses. Use minimum of 2" of insulation with a vapor barrier. The outside ductwork must be weather proofed between the unit and the building.

When attaching ductwork to a horizontal unit, provide a flexible water tight connection to prevent noise transmission from the unit to the ducts. The flexible connection must be indoors and molded out of heavy canvas.

Note: Do not draw the canvas taut between the solid ducts.

IMPORTANT(below 5.0RT) To convert to downflow, remove covers from the downflow supply and return air opening(painted side out) and secure with sheet metal screw (see Figure 3)

Note:

SUTTLY OPENING

1. Remove the screw nearest to the opening and pull the panel firmly toward the outside of the unit to disengage the back attachment.

RETURN OPENING

2. Remove right hand screw and move panel to the right or remove both screws.

A. CONDENSATE DRAIN

A 3/4 inch male condensate drain connection is located on the corner of the unit next to the evaporator section access panel. A trap should be installed and filled with water before starting the unit to avoid air from being drawn through. Follow local codes and standard piping practices when running the drain line. Pitch the line downward, away from the unit, and avoid long horizontal runs. See Figure 4.

Do not use reducing fittings in the drain lines. The condensate drain must be:

1. Made of 3/4" pipe size.

2. Pitched 1/4" per foot to provide free drainage to convenient drain system.

3. Trapped

4. Must not be connected to closed drain system.

B. OUTDOOR COIL CONDENSATE DRAINAGE PRECAUTION

Condensate drains from the outdoor coil during the heating and defrost cycles. Normally this condensate may be allowed to drain directly onto the ground/roof. A gravel bed is recommended to prevent mud splashing.

WARNING : The unit should not be installed in an area where mud or ice could cause personal injury.

Remember that condensate drips from the outdoor coil during heat and defrost cycles and that this condensate freezes when the temperature of the outdoor air is below 0°C(32°F)

■ Above 7.5RT

This Unit Filters are anti-bacteria and washable type.

Access to the filters is made by removing the evaporator fan access panel. Each unit ships with free filters, as determined by unit size.

On the filter access panel at the left side of the unit, "FILTER ACCESS PANEL" label is attached.

■ Below 6.25RT

This unit is shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork.

Important: Do not operate unit without filters in place.
