.
The filters must be in a near vertical position for the automatic
traps to work properly.
Both inlet compressed air filter elements must be replaced every 12 months, in order to properly
protect the system and to maintain the warranty on the system.
The element replacement must be documented to maintain the 2-year warranty.
These filters are supplied with a:
•
Automatic trap to drain away any liquid water or oil.
•
Differential air pressure indicator on top that changes to red when the filter element needs to be
replaced. This indicator changes when the air pressure drop across the filter element becomes
more than about 5 psi, which means that the filter element is loaded with particles & dust.
10.1.2 Round Re-Circulation Air Filter
(located on top the control cabinet)
To check or replace this filter, the system must be shut down and the filter housing
should be cool to the touch. Carefully remove the filter housing. The filter element can
be removed to inspect or replace. Any particles in the filter element can be vacuumed
out carefully, however it is better to replace the filter element when it is dirty, for better
performance of the system. Install the filter element and replace the filter housing on
top of the filter. Make sure the seal, where the lid mates onto the filter housing, is in
good condition.
10.1.3 Heater Housing Thermostat
(if supplied)
These are 3/8” npt by 2” long stainless steel adjustable thermostats that are used for
over temperature protection. The set point is factory set. If an adjustment is required,
turning the adjustment screw clockwise decreases the set point and turning the
adjustment screw counterclockwise increases the set point.
