Quincy Compressor-QSI ®
Fluid Sample Valve
QSI models are equipped with a fluid sample valve
located at the discharge of the fluid filter.
Figure 1-2. Fluid Sample Valve
Fluid samples should be taken from the sample valve
while the compressor is running at normal operating
temperature (see Sampling Procedures - page 39).
Fluid Filter
The fluid filter is a spin on, full flow unit. Replacement
of the filter requires spinning off the cartridge and
replacing it with a new one.
NOTICE!
Use genuine Quincy replacement filters only.
Figure 1-3. Spin-on Fluid Filter
The initial filter change should occur after the first 500
hours of operation. During normal service, the filter
cartridge should be replaced under the following
conditions, whichever occurs first:
• as indicated by the fluid filter maintenance indicator
when the fluid is at normal operating temperature
• every 1,000 hours
• every fluid change
NOTICE!
The fluid filter maintenance indicator may read
high upon start up on cool mornings due to
sluggish fluid creating higher than normal
differential pressures. Monitor indicator after the
fluid warms up.
