Operation
Check Drainage Bottles and Hoses
WARNING
INJECTION HAZARD
To reduce the risk of serious injury and property
damage, regularly check and clean the drain hose
and bottle for the automatic pressure relief valve.
If material is allowed to dry in and clog the drain
hose, the automatic pressure relief valve may not
fully release the fluid pressure if it opens or may
cause the drain hose to burst.
Check the drain hose and bottle (38) at the start of
each shift, and whenever there is an imbalance of
material, to see if the automatic pressure drain valve
has released material into the bottles. Clean the hose
and bottle as needed. Regularly check the drain hose
for cuts, leaks, or bulges and replace damaged compo-
nents before using the system. See Fig. 18.

Monitor Material Supply
Monitor system material supply regularly based on
system usage.
CAUTION
Establish a rigid system for monitoring the material
supply to prevent the pumps from running dry. A
sudden lack of material in one pump may cause
many system problems, including air entrapment,
spitting of the fluids, fluid “crossovers”, pump
damage, downtime, and added system stresses.
CAUTION
Never allow the feed pump or solvent pump contain-
ers to run dry. A dry container allows air to be
pumped into the system and causes incorrect propor-
tioning. A dry pump will quickly accelerate to a high
speed, and may damage itself and the other dis-
placement pump because it causes a pressure rise in
the other pump. If a supply container becomes dry,
stop the pump immediately, refill the container, and
prime the system again. Be sure to eliminate all the
air from the system before continuing the application.
NOTE:
The pump runaway valve mentioned on
page 13 of the Installation section shuts off the pump
if the pump speed accelerates quickly.
