MANUAL - SOLVENT RECYCLERS - URS1600 SERIES, URS2000 SERIES & RI 80 Rev 2019-05

1) CLEAN CONDENSER

Remove the 2 screws at the back of the Side Cover and carefully move the Side Cover forward just

enough to reach the front of the condenser with a vacuum. Using a brush attachment, vacuum the front of

the condenser where most of the dust accumulates and then vacuum the back if necessary. Put the Side

Cover back into position and re-install the screws.

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.
