SIZING
Determining dryer capacity at actual operating conditions.
Todeterminethemaximuminletowcapacityofadryeratvari-
ous operating conditions, multiply the rated capacity from Table
1 by the multipliers shown in Table 2.
Example: How many scfm can a 60 Hz air-cooled model 1000
handle when compressed air to be dried is at 200 psig and
100°F; ambient air temperature is 80°F?
Answer: 1,000 x 1.22 x 1.12 = 1,366 scfm.

 Whenremovingliquidsatratedowconditions,the
pressure drop will be 5 psi (0.35 bar), or less, across
the entire dryer. An increase in pressure drop will
occuronlyastheseparator/lterelementsbecome
loaded with solid particles. It is recommended, for
maximumltrationefciency,theseparator/lterele-
ments be replaced when the pressure drop across the
dryer exceeds 10 psi (0.7 bar), or every 12 months,
whicheveroccursrst.
2. Replacement of the Separator/Filters
Depressurize the unit before servicing.
Failure to do this may result in injury.
a. Open the bypass between compressed air inlet and
outlet. (if equipped)
b. Close the shut-off devices at the compressed air
inlet and outlet.
c. Press the Drain Test button on the control panel
(see page 5 for description and location) until the
system is depressurized.
d. Switch off the dryer.
e. Remove the insulation [1].
f. Loosenthescrews[2]ofthelterhousing.Caution
is necessary as the system may still be under slight
residual pressure.
g. Removeallscrewsexceptoneandswingange[3]
to the side.
h. Pull out the old cartridges [4].
i. Push new cartridges on to the mounting posts in the
bottom of the separator vessel.
NOTE: Do not touch the foam sleeves of the
cartridgeswithyourngers.
j. Close housing in reverse order.
k. Put on insulation.
l. Switch on the dryer.
m. Repressurize the dryer by slowly opening the
compressed air inlet valve.
n. Slowly open the compressed air outlet valve.
o. Slowly close the compressed air bypass valve (if
equipped).
3.3 Filter Monitor Programming (optional)
A. Each Filter Monitor needs to be initialized whenever a new
lterelementisinstalled.InitializationresetstheIntel-
ligence circuitry to begin establishing a new performance
baseline consistent with the unique signature of each
individual element.
B. To retain the existing settings previously established
simply:
1. Press and hold the “enter” button until the
programmingiconbeginsashing.
2. Slowlypressandreleasethe“enter”buttonve(5)
times.
3. Only the will appear on the LCD display for
therst2minutesofoperation.Initializationisnow
complete.
