SAFETY WARNINGS

 

 

DANGER: PERSONAL INJURY HAZARD  

Before performing service turn off 

electrical power to unit and 

observe the proper process of 

locking-out power at the 

main/disconnect box and follow all 

safety precautions outlined in unit’s 

IOM before performing any repairs 

to unit. 

 

 

WARNING: PERSONAL INJURY HAZARD 
 

Installation and servicing of this 

equipment can be hazardous due 

to system pressure and electrical 

components. Only trained and 

qualified personnel should install, 

repair, or service the equipment. 

 

 

WARNING: PERSONAL INJURY HAZARD 

When working on equipment, 

always observe precautions 

described in the literature, tags, 

and labels attached to the unit. 

Follow all safety codes. Wear safety 

glasses and work gloves. Use a 

quenching cloth for brazing, and 

place a fire extinguisher close to 

the work area. 

 

 

WARNING: PERSONAL INJURY HAZARD 

R410A is flammable when exposed 

to open flame. Recover all 

refrigerant prior to brazing.

 

 

 

NOTICE: 

All refrigerant discharged 

from this unit must be recovered 

WITHOUT EXCEPTION.

 

Technicians must follow industry 

accepted guidelines and all local, 

state, and federal statutes for the 

recovery and disposal of 

refrigerants. If a compressor is 

removed from this unit, refrigerant 

circuit oil will remain in the 

compressor. To avoid leakage of 

compressor oil, refrigerant lines of 

the compressor must be sealed after 

it is removed.
