(Single Stage Application For 38C Only) 

 
 
 
A.  Safety Considerations

 

Only  trained  service  technicians  familiar  with  standard  service  instructions  and  training  materials  should  attempt  installation,  service, 

and  repair  of these  units.   Improper  installation,  adjustment,  alteration,  service,  maintenance,  or  use  can  cause  explosion,  fire,  electrical 

shock,  or  other  conditions  which  may  cause  death,  personal  injury,  or  property  damage.  Consult  a qualified  installer,  service  agency,  or 

your  distributor  or  branch  for  information  or  assistance.    The  qualified  installer  or  agency  must  use  factory  - authorized  kits  or 

accessories  when modifying  this product. Refer to the individual instructions  packaged with the kits or accessories  when installing.

 

Follow  all  safety  codes.  Wear  safety  glasses,  protective  clothing,  and  work  gloves.  Use  quenching  cloth  for  brazing  operations.  Have 

fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the 

unit. Consult local building codes and National Electrical Code (NEC) for special requirements.

 

 

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  these  signal  words;  DANGER,  WARNING,  and  CAUTION.    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.

 

 

WARNING

 

 

ELECTRICAL  SHOCK HAZARD

 

Failure to follow this warning could result in personal injury or death.

 

All equipment should be installed in accordance  with accepted practices and unit Installation  Instructions,  and in compliance  with all 

national  and  local  codes.  Power  should  be  turned  off  when  servicing  or  repairing  electrical  components.  Extreme  caution should 

be  observed  when  troubleshooting  electrical  components  with  power  on.  Observe  all  warning  notices  posted  on  equipment  and  in 

instructions or manuals.

 

 

WARNING

 

 

EXPLOSION  AND PERSONAL SAFETY HAZARD

 

Failure to follow this warning could result in personal injury, equipment damage or improper operation.

 

Refrigeration systems  contain  refrigerant  under  pressure.  Puron

®

 

refrigerant  (R- 410A)  systems  operate  at  higher  pressure  than 

standard  R- 22  systems.    Use  only  service  equipment  and  components rated  for  Puron

®

 

refrigerant.  Extreme  caution  should  be 

observed  when  handling  refrigerants.  Wear  safety  glasses  and  gloves  to prevent  personal  injury.  During  normal  system  operations, 

some components  are hot and can cause burns. Rotating  fan blades  can cause personal  injury.  Appropriate  safety considerations are 

posted throughout this manual where potentially dangerous techniques are addressed.
