THESE UNITS REQUIRE R-410A 

REFRIGERANT AND POLYOL 

ESTER OIL.

GENERAL:

1.  Use separate service equipment to avoid cross    

 

contamination of oil and refrigerants.

2.  Use recovery equipment rated for R-410A  

 

 refrigerant.
3.  Use manifold gauges rated for R-410A (800 psi/250  

 

psi low).

4.  R-410A is a binary blend of HFC-32 and HFC-125.
5.  R-410A is nearly azeotropic - similar to R-22 and  

 

R-12.  Although nearly azeotropic, charge with   

 

liquid refrigerant.

6.  R-410A operates at 40-70% higher pressure than   

 

R-22, and systems designed for R-22 cannot    

 

withstand this higher pressure.

7.  R-410A has an ozone depletion potential of zero,  

 

but must be reclaimed due to its global warming  

 potential.
8.  R-410A compressors use Polyol Ester oil.
9.  Polyol Ester oil is hygroscopic; it will rapidly    

 

absorb moisture and strongly hold this moisture in  

 

the oil.

10. A liquid line dryer must be used - even a deep    

 

vacuum will not separate moisture from the oil.

11. Limit atmospheric exposure to 15 minutes.
12. If compressor removal is necessary, always plug  

 

compressor immediately after removal.  Purge with  

 

small amount of nitrogen when inserting plugs.

TOPPING OFF SYSTEM CHARGE

If a leak has occurred in the system, Bard 

Manufacturing recommends reclaiming, evacuating 

(see criteria above), and charging to the nameplate 

charge.  If done correctly, topping off the system charge 

can be done without problems.

With R-410A, there are no significant changes in the 

refrigerant composition during multiple leaks and 

recharges.  R-410A refrigerant is close to being an 

azeotropic blend (it behaves like a pure compound 

or single component refrigerant).  The remaining 

refrigerant charge, in the system, may be used after 

leaks have occurred and then “top-off” the charge by 

utilizing the pressure charts on the inner control panel 

cover as a guideline.

REMEMBER:  

When adding R-410A refrigerant, it 

must come out of the charging cylinder/tank as a liquid 

to avoid any fractionation, and to insure optimal system 

performance.  Refer to instructions for the cylinder that 

is being utilized for proper method of liquid extraction.

SAFETY PRACTICES:

1.  Never mix R-410A with other refrigerants.
2.  Use gloves and safety glasses, Polyol Ester oils can  

 

be irritating to the skin, and liquid refrigerant will  

 

freeze the skin.

3.  Never use air and R-410A to leak check; the    

 

mixture may become flammable.

4.  Do not inhale R-410A – the vapor attacks the    

 

nervous system, creating dizziness, loss of  

 

 

coordination and slurred speech.  Cardiac  

 

 

irregularities, unconsciousness and ultimate death  

 

can result from breathing this concentration.

5.  Do not burn R-410A.  This decomposition  

 

 

produces hazardous vapors.  Evacuate the area if  

 exposed.
6.  Use only cylinders rated DOT4BA/4BW 400.

7.  Never fill cylinders over 80% of total capacity.

8.  Store cylinders in a cool area, out of direct  

 

 sunlight.
9.  Never heat cylinders above 125°F.
10. Never trap liquid R-410A in manifold sets, gauge  

 

lines or cylinders.  R-410A expands significantly  

 

at warmer temperatures.  Once a cylinder or line is  

 

full of liquid, any further rise in temperature will  

 

cause it to burst.

        WARNING

Failure to conform to these practices 

could lead to damage, injury or death.
