Jameson Aftercooler: Operation and Maintenance Manual
Description of operation
A Jameson Aftercooler is a portable system consisting of an air-cooled trim cooler and a
separator/filter. Wet warm air enters the trim cooler where it is cooled to a temperature
approaching ambient. Water is condensed out during this cooling process. The saturated air
and the liquid water proceed to the inlet of the separator/filter where the liquid water is
removed. The process air out of the system is ready for use.

Operation
The simple design of the system allows for easy operation. The system requires daily filter
draining and periodic cooler draining to ensure peak performance.
Setup
1. Connect air line from compressor to inlet side of aftercooler, ensure proper
safety clips are installed.
2. Connect air line from aftercooler to equipment, ensure the outlet ball valve
is closed.
3. Slowly pressurize the system and allow some air to bleed through the drain
valves. Once there is no additional liquid coming through the valves they
can be closed.
4. Adjust motor supply pressure to meet the pressure specifications in Table 1
Main Filter Draining – The accumulated water and oil solution should be drained
from the main filter every 4 to 8 hours (or as required based on environmental
conditions).
*If the filter is not drained regularly, it may become flooded and the accumulated
liquid may enter the air system and cause damage to downstream equipment.
Locate the drain valve at the bottom of the large filter assembly. Turn the
fitting to open the valve and drain liquid from the filter assembly. Once
liquid has finished draining close the valve.

Motor Filter Draining -The accumulated water and oil solution should be drained
from the main filter every 2 to 4 hours (or as required based on environmental
conditions).
Locate the drain valve at the bottom left of the motor regulator assembly.
Turn the fitting to open the valve and drain liquid from the filter assembly.
Once liquid has finished draining close the valve.
Cooler Draining – The accumulated water and oil solution should be drained from
the radiator assembly periodically to prevent the cooler from becoming flooded.
Remove supply hose on bottom of radiator assembly and allow any liquid to
drain. Reattach the hose and check for air leaks.
Motor Lubrication – The pneumatic motor should be lubricated to run properly.
The bowl located on the right side of the motor regulator assembly is for pneumatic
tool oil. Fill to the appropriate fill lines indicated on the bowl.
Maintenance
Daily Inspection
•Check the operating conditions, ambient temperature and inlet pressure.
•Monitor the unit to make sure it is operating properly.
•Test separator filter drain for proper draining.
•Visually check the unit piping for damage or leaks
Scheduled Maintenance
12 Months
•Replace the separator filter element
•Clean the exterior of the aftercooler
24-60 Months
•Periodically the aftercooler core should be cleaned internally if the
process air contains excessive amounts of lubricating fluids

Cleaning the outside of the aftercooler core
The core should be cleaned regularly. Accumulation of dirt or other
contaminants such as oils will greatly reduce the efficiency of the pre-
cooler.
Normal accumulation of dirt can be removed by blowing the core off with
compressed air. If the core becomes contaminated with oil-laden particles,
it can be steam cleaned. Clean with extreme care as the aluminum fins can
be easily damaged.
Preparation for Storage
Shut off the air supply to the Aftercooler and open the filter drain valve to
completely depressurize the system.
Open the filter drain valve to drain all accumulated liquid in the cooler.
Disconnect the inlet and outlet air hoses.
STORAGE
Store the Aftercooler in a location that is free from extreme humidity and
corrosive gasses, which can cause damage to the unit.
