Section 1 – SR-2 Safety Information
Union, national, federal, state and/or local
regulations governing the use of refrigerants
and certification of technicians.
When refrigerants are exposed to the atmosphere in
liquid form, they evaporate rapidly, freezing anything
they contact. If they contact the skin severe frostbite
can result. In the event of frostbite, the objectives of
first aid are to protect the frozen area from additional
injury and to warm it rapidly.
Refrigerant First Aid
1. Warm the frozen area by immersing it in luke-
warm (not hot) water or by covering the area
with warm blankets.
2. Obtain medical assistance as soon as possible.
3. If refrigerant contacts the eyes, flush them with
water immediately and obtain medical assist-
ance as soon as possible.
REFRIGERATION OIL
Avoid contact with the eyes. Avoid prolonged
contact with the skin or clothing. To prevent skin
irritation wash hands thoroughly after handling
refrigeration oil.
Refrigeration Oil First Aid
In case of eye contact, flush immediately with water
for at least 15 minutes. Obtain medical assistance
as soon as possible.
ELECTRICAL
CONSIDERATIONS
Microprocessor Service
Precautions must be taken to prevent electrostatic
discharge when servicing the microprocessor and
related components. A potential difference less than
that required to create a small spark between a
finger and a doorknob can cause severe damage to
solid state components. Refer to the material in this
manual and the Electrostatic Discharge Training
Guide (TK 40282) for additional information.
Welding
Precautions must be taken before welding on the
unit. Refer to Service Procedure A26A in Section 6
of this manual for additional information.
