Do  not  use  a  nitrogen  cylinder  without 
a pressure  regulator.  Cylinder  pressure 
is approximately  159.9  bar  (2350  psig). 
Do not use  oxygen  in  or  near  a  refrigerant 
system  as  an  explosion  may  occur.  (See 
Figure 8-19) 
 
High  voltage  (dielectric)  testing  must  not 
be  performed  on  the  machine  without  first 
observing  NEMA  rules.  The  insulation  of 
this  generator  winding  may  be  safely 
checked by using a megohm meter. A high 
reading indicates good insulation.  
 
Generators  of  this  type  should  not  be 
"flashed".  Operation  with  external  voltage 
source or momentary shorting of leads will 
damage the generator and may cause inju-
ry.  
 
Under no circumstances should anyone at-
tempt  to  repair  the  Logic  or  Display 
Boards.  Should  a  problem  develop  with 
these  components,  contact  your  near-
est Carrier  Transicold  dealer  for  replace-
ment.  
 
Service  Mode  MUST be used  whenever re-
moving  refrigerant  charge,  refrigerant  leak 
checking or evacuating. 
 
The  display  and  MessageCenter  may  be-
have  differently  during  the  software  load-
ing  process,  depending  on  the  version  of 
software  currently  in  the  controller.  DO 
NOT  INTERRUPT  THE  SOFTWARE  IN-
STALLATION  PROCESS  ONCE  IT  HAS 
STARTED. 
 
Unit  uses  R-404A OR  R-452A  and  POE oil. 
The use of inert gas brazing procedures is 
mandatory  for  all Carrier  Transicold  refrig-
eration units; otherwise compressor failure 
will  occur.  For  more  information  Refer  to 
Technical Procedure 98-60068-00 Inert Gas 
Brazing 
 
When  changing  oil  filter,  the  new  filter 
should  be  primed  (partially  filled) 
with clean  oil  if  possible.  If  the  filter  is 
not primed,  the  engine  may  operate  for 
a period  with  no  oil  supplied  to  the  bear-
ings. 
 
Use only monopropylene glycol anti-freeze 
as glycol  by  itself  will  damage the  cooling 
system.  Always  add  pre-mixed  50/50  anti-
freeze  and  water  to  radiator/engine.  Never 
exceed  more  than  a  60%  concentration  of 
anti-freeze. Use a low silicate anti-freeze.  
 
The mica shim must be used during disas-
sembly  of  the  generator  from  the  engine. 
Never attempt to remove the rotor from the 
stator.  Leave  the  shim  in  place  until  the 
generator is re-installed on the engine. 
 
NEVER  POUR  COLD  WATER  INTO  A  HOT 
ENGINE, however hot water can always be 
added to a cold engine. 
 
Only a  refrigerant  drum  containing  R-404A 
or  R-452A  should  be  connected  to  this  re-
frigeration  unit  in  order  to  pressurize  the 
system.  However,  dry  nitrogen  may  be 
used  to  increase  pressure.  Any  other  gas 
or  vapor  will  contaminate  the  system  and 
require additional purging and evacuation.
