Quincy Compressor QSI Series Instruction Manual page 93

Fluid Sample Valve
QSI models are equipped with a fluid sample valve lo-
cated 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 tem-
perature (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 replac-
ing it with a new one.
NOTICE!
Use genuine Quincy replacement filters only.
Section VII - Compressor Fluids
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 car-
tridge 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 dif-
ferential pressures. Monitor indicator after the
fluid warms up.
