POST INSTALLATION CHECK LIST 
 
 
 
  
						

							POST AIR CONDITIONING SYSTEM INSTALLATION 
CHECKLIST 
Confirmation of proper direction of rotation of Evaporator  Blower Wheels. 
(See  Electrical  System Dwg.) 
Note: 
Blower will work with  blower  wheel rotating in incorrect direction, 
But airflow  will be significantly  decreased, degrading system performance. 
_ Refrigerant Plumbing system  oil charged.  (See Plumbing Inst! Dwg.) 
_  Check  Compressor  hose routing  and clamping  to avoid  hose kinking  in the  bend 
radius 
_  Check  Condenser  Blower to insure  that fan bladelhousing  clearing exist. Look  for 
wear  marks  on inside 
of fan  shourd. If rubbing  exist contact  Air Comm  Corporation 
_ 
Prior to  charging  the system,  we recommend  leak checking  with dry nitrogen  at 
(150 psi) using  soap and water  solution  to bubble  check connections. 
_  Charge  system according  to instructions. 
If system  is undercharged  or overcharged 
the 
AIC will  not work  provide  maximum  cooling. For R-134a  system,  overcharging 
system  will degrade  performance  more than slightly  undercharging. 
_  Leak  check  all joints  after system  charging,  using an electronic  leak detector*.  This 
is  critical to  insure continued  optimum 
AlC performance. Use torque seal after 
torquing 
of joints  and leak  checkhas  satisfactorily  been performed. 
*Note: 
Using other than an electronic detector for final leak detection  is 
unreliable and may allow some slow leaks  to go undetected 
_  Check  Evaporator  air ducting 
to insure that: 
_ Ducts  are securely  clamped  to duct  connections 
_ Duct  liner wire is in  place  to preclude  collapse. 
_  Insure  louvers  are properly  installed per drawing. 
_The Condenser  Heat Exchanger  rubber seal strip  is properly  positioned  to insure  a 
complete seal  exist between  the condenser  heat exchanger  and lower  aft fuselage 
f  airing.  Inspect  condenser  inlet screen  for proper  security. 
_  The three  lightening  holes located  at the  lower  aft edge 
of baggage  floor are properly 
sealed.  (See Condenser 
lnst Dwg). 
_  Insure  proper  alignment 
of compressor  and tail rotor  drive  pulley.  Check for proper 
belt  tension 
per drawing,  Inspect for correct  mounting of compressor per drawing.
