(E)-equipped chiller that has
accum ulated 80 m inutes of purge pum p-out tim e since the
last carbon tank regeneration w ould be estim ated to have
84 percent carbon tank capacity rem aining:
100 – (80/350)* 100 = 84%
The purge controls m ay initiate a carbon tank regeneration
cycle w hen the rem aining carbon tank capacity is
calculated to be less than 80 percent. How ever, the
continued stable operation of the chiller is always m ore
im portant than the regeneration of the carbon tank.
Therefore, the follow ing rules apply:
1. If the Daily Pum p-out Lim it is disabled, a regeneration
cycle m ay not be initiated, regardless of the value of
the rem aining carbon capacity.
Also, if the Daily Pum p-out Lim it is disabled during a
regeneration cycle, the regeneration cycle m ust be
term inated.
2. When the rem aining carbon capacity is less than
80 percent, a regeneration cycle w ill be initiated at the
next opportunity w hen the chiller is running (after the
chiller has started and no pum p-out m inutes have
accum ulated for the previous 60 m inutes).
3. If there is no opportunity to purge as indicated by Rules
1 and 2 and the rem aining carbon capacity is less than
50 percent, a regeneration cycle w ill be initiated at the
best opportunity w hen the chiller is shut dow n (and no
pum p-out m inutes have accum ulated for the previous
60 m inutes).
4. If there is no opportunity to regenerate as indicated by
Rules 1, 2, and 3, and the carbon capacity drops below
0 percent, then a regeneration cycle is initiated.
5. Note that if at any tim e during the regeneration cycle,
the chiller is running and shuts dow n or if the chiller is
off and starts up, then the regeneration cycle is
continued.
Carbon Tank Regeneration Sequence
N ot e: Graphic labels (show n above) are used for CE
application only.
Im port ant :
• Before servicing, disconnect all pow er sources and
allow at least 30 m inutes for capacitors to discharge.
• All electrical enclosures—unit or rem ote—are IP2X.
If the purge controller determ ines that carbon tank
regeneration is desired and is allow ed, the purge controls:
1. Disable the purge refrigeration circuit and the pum p-
out solenoid valve.
2. Open the regeneration solenoid valve and turn on the
carbon tank heater.
3. M onitor the carbon tem perature until it reaches the
regeneration tem perature value of 115.6°C (240°F), and
control w ithin a ±5.6°C (±10°F) dead band for
15 m inutes (this step should take approxim ately
3 hours).
WARNING
Hazardous Voltage
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
pow er, including remote disconnects before servicing.
Follow proper lockout/ tagout procedures to ensure the
pow er can not be inadvertently energized.
