Shutdown and Care of the System
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
follow the
Pressure Relief Procedure
on page 19 whenever you are instructed
to relieve the pressure.
System Shutdown
To shut the system down, shut off the air to all pumps,
trigger the dispensing valve into a grounded metal
waste container. Close the mixer manifold valves.
Flush all the mixed fluid out of the mixer manifold,
hoses and dispensing equipment. See page 17. Then
follow the
Pressure Relief Procedure , page 19.
Cleaning the Pump Inlet Strainer
If the fluid pressure from the feed pump to the propor-
tioning pump cannot be maintained on the propor-
tioning pump intake gauge (J1), check and clean the
strainer (V). See Fig. 17, page 21.
Care of the Pump Throat Packing Nuts
Keep the throat packing nuts (JJ) filled with appropri-
ate lubricant and check the tightness of the packing
nut weekly. See Fig. 19.
Always follow the Pressure Relief Procedure , page
19, before adjusting the packing nut. The packing nut
should be tight enough to prevent leakage; no tighter.
Too tight an adjustment causes the packings to bind or
wear prematurely and leak.
