14.0. PREVENTATIVE MAINTENANCE: (Cont.):
14.34. LDENS SAMPLE LINE FILTER (Used with optional Auto
Concentrate Monitor and Adjust) - CHANGING:
THIS CAN ONLY BE REPLACED WHEN THE CHIPBLASTER IS SHUT
DOWN.
The LDENS filter is not monitored because of the very low flow rate. The cartridge filter should
be changed every 30 days under normal conditions. If there is a high volume of way oil (in the
case of lathes) the filter should be changed more often. The tell tail signs of a dirty filter
cartridge are:
• Erratic density readings (large fluctuations between readings).
• A large difference between the percent of concentrate read on a refractometer and the
percentage shown on the HMI. If a large amount of way oil is present in the coolant a
good refractometer reading may be difficult.
14.34.1. Power down ChipBLASTER unit.
14.34.2. Depress pressure release button to relieve pressure in filter housing.
14.34.3. Unscrew housing using spanner wrench.
NOTE: When opening filter housing to change cartridge, it is common for
o- ring/Gasket to lift out of housing and stick to cap. Remove used cartridge and
discard. Rinse out housing and fill about 1/3 full with clean premixed coolant.
NOTE: Make sure the o-ring is seated level in the groove (or gasket is on rim of
sump).
CAUTION: If a ring gasket appears damaged or crimped it should be replaced at
this time. Contact ChipBLASTER service for replacement parts.
14.34.4. Insert a new cartridge into the sump making sure that it slips down over the
sump standpipe.
14.34.5. Screw the sump onto the cap and hand tighten. DO NOT OVER-TIGHTEN.
Make sure cartridge slips over the cap standpipe.
14.34.6. Turn on power to the ChipBLASTER and energized a call for coolant. Allow
the ChipBLASTER to run until the “DELAY BEFORE SAMPLE” timer in the
PLC times out and a coolant sample is diverted through the filter. Check for any
leaks. The ChipBLASTER may require several samples before the filter housing
and sample line is purged of air.
14.37. EQUIPMENT COOLAING FANS - CLEANING:
14.37.1.To clean the equipment cooling fans, first power down the ChipBLASTER unit
by turning off the main disconnect and locking it out.
14.37.2. Use a soft bristle brush to clean the fan blades. If dirt is caked on it may be
necessary to remove the fan guard to clean, use a mild soap and water with stiff
bristle brush to clean the fan blades. Be careful not to damage the fan blades.
Replace the fan guards before returning the ChipBLASTER to service.
DO NOT USE COMPRESSED AIR TO CLEAN EQUIPMENT COOLING
FANS.
