FIELD CONVERSION OF DISCHARGE AIR — The dis- charge air of the 50PSH 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. 7 and 8.

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

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

Units are for indoor use only.

Locate in areas where ambient temperatures are between 39 F and 102 F 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 ductwork 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.
