SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components. Only

trained and qualified service personnel should install, repair, or

service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of

cleaning coils and filters and replacing filters. All other operations

should be performed by trained service personnel. When working

on air-conditioning equipment, observe precautions in the

literature, tags and labels attached to the unit, and other safety

precautions that may apply.

Follow all safety codes, including ANSI (American National

Standards Institute) Z223.1. Wear safety glasses and work gloves.

Use quenching cloth for unbrazing operations. Have fire

extinguisher available for all brazing operations.

It is important to recognize safety information. This is the safety-

alert symbol . When you see this symbol on the unit and in

instructions or manuals, be alert to the potential for personal

injury.

Understand the signal words DANGER, WARNING, CAUTION,

and NOTE. These words are used with the safety-alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies hazards

which could result in personal injury or death. CAUTION is used

to identify unsafe practices, which may result in minor personal

injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability,

or operation.

Fan Technology

GENERAL

These installation instructions cover the 50FC units with cooling

only. Units are pre-wired and pre-charged with environmentally

balanced Puron

(R-410A) refrigerant at the factory. See Fig. 1 for

model number nomenclature. See Fig. 2-16 for unit dimensions.

See Fig. 5, 10, and 15 for service clearances.

Rated Indoor Airflow (cfm)

Table 1 lists the rated indoor airflow used for the AHRI efficiency

rating for the units covered in this document.

NOTE: Unit is not designed to have overhead obstruction. Contact

Application Engineering for guidance on any application planning

overhead obstruction or for vertical clearances.

DANGER

ELECTRICAL SHOCK HAZARD

Failure to follow this warning will result in personal injury or

death.

Before performing service or maintenance operations on unit,

turn off main power switch to unit and install lock(s) and

lockout tag(s). Ensure electrical service to rooftop unit agrees

with voltage and amperage listed on the unit rating plate. Unit

may have more than one power switch.

WARNING

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could cause personal injury,

death and/or equipment damage.

R-410A refrigerant systems operate at higher pressures than

standard R-22 systems. Do not use R-22 service equipment or

components on R-410A refrigerant equipment.

WARNING

PERSONAL INJURY AND ENVIRONMENTAL

HAZARD

Failure to follow this warning could cause personal injury or

death.

Relieve pressure and recover all refrigerant before system

repair or final unit disposal.

Wear safety glasses and gloves when handling refrigerants.

Keep torches and other ignition sources away from

refrigerants and oils.

CAUTION

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs. Use care and

wear appropriate protective clothing, safety glasses and gloves

when handling parts and servicing air conditioning equipment.
