INSTALLATION

LIMITATIONS

Theseunits mustbeinstalled inaccordancewithapplicablena tional, local and municipal safety codes.

If components are to be added to a unit to meet local codes, theyare tobe installedatthedealer'sand/or thecustomer's ex pense. Refer to Table 2 for Unit Application Data.

LOCATION

This blowerunit is notdesigned for outdoorinstallation. Itmust be locatedwithin the buildingstructure, either insideor outside the conditioned space.

The unit should be located as close to the condensing unit as practical and positioned to minimize bends in the refrigerant piping.

Unitsbeing installedverticallyorhorizontallycan besetdirectly on a floor or platform, or they can be supported by metal or wooden beams.

Units being installed horizontally can also be suspended from above. Refer to the suspension accessory instruction installa tion procedures.

CLEARANCES

The clearanceslisted on theunit dimension drawing(Figure 7) are required for the proper service and operation of the unit.

RIGGING AND HANDLING

Becareful whenmovingtheunit.Do notremove anypackaging until the unit is near its final location.

The packaging consists of a bottom wooden skid that can be lifted witha fork truck from anydirection, a clear heavy milbag that coversthe entire unit,and strapping thatsecures the clear bag to the bottom of the skid.

1.Remove the panels from the blower section.

2.Remove the four Phillips machine bolts that hold the coil and blower sections together. A bolt is located near each corner.

3.Move the blower section to the proper location.

4.Attach the blower section to the coil section with the machine bolts removed in Step 2.

6.Replace the panels.

DUCT CONNECTIONS

All ducts should be designed and installed in accordance with applicable national and/or local codes.

Ducts should be sized no smaller than the duct flanges on the unit or the accessory electric heater(ifused).Refer to the unit dimensions(Figure7) andthe heaterdetail (Figure2) forthese sizes.

The field installed air plenum and return air grille accessories shouldbeused inplace of ductworkonly whenafree blow/free return application is practical.

REFRIGERANT MAINS

Many service problems can be avoided by taking adequate pre

cautionsto providean internallycleananddrysystem,andbyus ing procedures and materials that conform with established standards.

Hard drawncoppertubing should be usedwhere no appreciable amount of bending around pipes or other obstructions in necessary.Use long radius ells whereverpossible.If soft copper is used, care should be taken to avoid sharp bends which may cause a restriction.

Pack fiberglass insulation and asealing material such asPermagum aroundrefrigerant lines wherethey penetrate awallto reduce vibration and to retain some flexibility.

Support all refrigerant lines at minimumintervalswithsuitable hangers, brackets or clamps.

Braze all copper to copper joints witH Sil-Fos 5 or equivalent brazing material. Do not use soft solder.

Never braze or solder liquid and suction lines together. The complete suction line should be insulated with no less the (12mm) ARMAFLEX or equivalent.

If it is desirable to tape or wire the liquid and suction lines to gether for support purposes, they must be completely insu lated from each other.

INSTALLING REFRIGERANTMAINS The units are evacuated and dehydrated at the factory and

shipped with a holding charge of Refrigerant-22. The suction and liquid connections are sealed with copper disks.

WARNING: Provisions for recovering refrigerant releases

If the unit has already lost itsholdingcharge, it should be leak tested and the necessary repairs should be made. If the unit has maintaineditsholding charge, you can assume that ithas no leaks and proceed with the installation.

Make sure the refrigerant in the lines has been recovered, then drill a small hole through the discs to prevent any inter nal pressure from blowing them off and to allow the flow of dry nitrogen through the connections when unbrazing the closures.

must be available during all phases of installation, leak testing and charging. Do NOT release refrig erantinto theatmosphere. ASchradervalveispro vided on the coil header for recovering refrigerant holding charge.
