SERVICE PROCEDURES
1) CLEAN CONDENSER
Using a brush attachment, vacuum the condenser at the back of the unit.
2) CLEAR BLOCKED SOLVENT FLOW PATH
CAUTION:
WEAR SAFETY GOGGLES.
A blockage in the solvent fl ow path (Vapour Outlet - Condenser - Solvent Outlet Tube) can cause solvent
to leak. To determine the location of the blockage, fi rst check the Solvent Outlet Tube and the Vapour
Outlet Fitting for visible signs of blockage or damage. If the problem is not in either of these locations, the
Condenser is problably blocked. To clear the condenser, pour some clean solvent into the Vapour Outlet
and check if it comes out of the Solvent Outlet Tube. If the blockage persists, blow air at about 30 PSI (2
kg/cm2) into the Vapour Outlet. If the air comes out of the Solvent Outlet Tube, the blockage has been
cleared. If not, call for service.
