Carrier 50RHE006-060 specifications Units are for indoor use only

Step 3 — Unit Location — The following guidelines should be considered when choosing a location for a WSHP unit:

•Units are for indoor use only

•Locate in areas where ambient temperatures are between 4.4 C and 37.8 C and relative humidity is no greater than 75%

•Provide sufficient space for water, electrical and duct connections

•Locate unit in an area that allows easy access and removal of filter and access panels

•Allow enough space for service personnel to perform maintenance

•Return air must be able to freely enter the space if unit needs to be installed in a confined area such as a closet

NOTE: Correct placement of the horizontal unit can play an important part in minimizing sound problems. Since duct- work is normally applied to these units, the unit can be placed so that the principal sound emission is outside the oc- cupied space in sound-critical applications. A fire damper may be required by the local code if a fire wall is penetrated.

FIELD CONVERSION OF DISCHARGE AIR — The dis- charge air of the 50RHE horizontal units can be converted between side and back discharge in the field. The conversion process is the same for right and left return configurations. See Fig. 3 and 4.

NOTE: It is not possible to convert return air between left or right return models in the field due to refrigerant piping changes.

Preparation — The unit should be on the ground in a well lit area for conversion. Hung units should be taken down to ground level before converting.

Side to Back Discharge Conversion

1.Remove screws to free the top and discharge panels. See Fig. 3.

2.Remove the access panel and set aside.

3.Lift the discharge panel from side of unit and rotate it to back using care not to damage blower wiring.

4.Check blower wire routing and connections for excessive tension or contact with sheet metal edges. Re-route if necessary.

5.Check refrigerant tubing for contact with other compo- nents. Adjust if necessary.

6.Reinstall top panel using screws set aside in Step 1.

NOTE: Location for some screws at bottom of discharge panel may have to be changed.

7.	Manually spin fan wheel to check for obstructions.
	Adjust for any obstruction found.
8.	Replace access panel.
