IMPORTANT INFORMATION
SAFE REFRIGERANT HANDLING
While these items will not cover every conceivable situaon, they should serve as a useful guide.
WARNING
R
EFRIGERANTS ARE HEAVIER THAN AIR.
T
HEY CAN "PUSH OUT" THE
OXYGEN IN YOUR LUNGS OR IN ANY ENCLOSED SPACE.
T
O AVOID
POSSIBLE DIFFICULTY IN BREATHING OR DEATH:
•
N
EVER PURGE REFRIGERANT INTO AN ENCLOSED ROOM OR SPACE.
B
Y
LAW, ALL REFRIGERANTS MUST BE RECLAIMED.
•
I
F AN INDOOR LEAK IS SUSPECTED, THOROUGHLY VENTILATE THE AREA
BEFORE BEGINNING WORK.
•
L
IQUID REFRIGERANT CAN BE VERY COLD.
T
O AVOID POSSIBLE FROST-
BITE OR BLINDNESS, AVOID CONTACT WITH REFRIGERANT AND WEAR
GLOVES AND GOGGLES.
I F LIQUID REFRIGERANT DOES CONTACT YOUR
SKIN OR EYES, SEEK MEDICAL HELP IMMEDIATELY.
•
A LWAYS FOLLOW EPA REGULATIONS. N EVER BURN REFRIGERANT,
AS POISONOUS GAS WILL BE PRODUCED.
WARNING
T O AVOID POSSIBLE EXPLOSION:
•
N
EVER APPLY FLAME OR STEAM TO A REFRIGERANT CYLINDER.
I
F YOU
MUST HEAT A CYLINDER FOR FASTER CHARGING, PARTIALLY IMMERSE
IT IN WARM WATER.
•
N EVER FILL A CYLINDER MORE THAN 80% FULL OF LIQUID REFRIGERANT.
•
N EVER ADD ANYTHING OTHER THAN R -22 TO AN R -22 CYLINDER OR
R -410 A TO AN R -410 A CYLINDER. T HE SERVICE EQUIPMENT USED MUST
BE LISTED OR CERTIFIED FOR THE TYPE OF RE
FRIGERANT USED.
•
S
TORE CYLINDERS IN A COOL, DRY PLACE.
N
EVER USE A CYLINDER
AS A PLATFORM OR A ROLLER.

HAS ISSUED VARIOUS REGULATIONS REGARDING THE INTRODUCTION AND
DISPOSAL OF REFRIGERANTS INTRODUCED INTO THIS UNIT.

AILURE TO
FOLLOW THESE REGULATIONS MAY HARM THE ENVIRONMENT AND CAN
LEAD TO THEH IMPOSITION OF SUBSTANTIAL FINES.

HESE REGULATIONS
MAY VARY BY JURISDICTION.

WARNING
S
YSTEM CONTAMINANTS, IMPROPER SERVICE PROCEDURE AND/OR PHYSICAL
ABUSE AFFECTING HERMETIC COMPRES
SOR ELECTRICAL TERMINALS
MAY
CAUSE DANGEROUS SYSTEM VENTING.
The successful development of hermecally sealed refrigeraon
compressors has completely sealed the compressor's moving
parts and electric motor inside a common housing, minimizing
refrigerant leaks and the hazards somemes associated with
moving belts, pulleys or couplings.
Fundamental to the design of hermec compressors is a method
whereby electrical current is transmied to the compressor mo-
tor through terminal conductors which pass through the com-
pressor housing wall. These terminals are sealed in a dielectric
material which insulates them from the housing and maintains
the pressure ght integrity of the hermec compressor. The ter-
minals and their dielectric embedment are strongly constructed,
but are vulnerable to careless compressor installaon or main-
tenance procedures and equally vulnerable to internal electrical
short circuits caused by excessive system contaminants.
In either of these instances, an electrical short between the
terminal and the compressor housing may result in the loss of
integrity between the terminal and its dielectric embedment.
This loss may cause the terminals to be expelled, thereby vent-
ing the vaporous and liquid contents of the compressor housing
and system.
A venng compressor terminal normally presents no danger to
anyone, providing the terminal protecve cover is properly in
place.
If, however, the terminal protecve cover is not properly in
place, a venng terminal may discharge a combinaon of
(a) hot lubricang oil and refrigerant
(b) ammable mixture (if system is contaminated
with air)
in a stream of spray which may be dangerous to anyone in the
vicinity. Death or serious bodily injury could occur.
Under no circumstances is a hermec compressor to be elec-
trically energized and/or operated without having the terminal
protecve cover properly in place.
See Service Secon S-17 for proper servicing.
