Installation
Typical Mountings
See Fig. 1 for typical mountings. See page 14 for the
mounting hole layout.
Install the surge tank or filter near the pump outlet.
Position the surge tank so the labels face away from
the pump and so the setscrews, near the top and
bottom of the tank, face toward the pump.
Exposed Mountings
Detail A: With Riser Tube
The top of the surge tank must always be supported.
See Accessories on page 13 for mounting clamps.
Surge tanks must always be mounted upright, as
shown in Fig. 1, not horizontally.
Detail B: No Riser Tube
Detail C: Integral Riser Tube

Operation
Before operating the equipment, be sure the drain
valve is closed.
Flush the equipment with a compatible solvent to
remove oil used for factory testing and rust prevention.
If you notice excessive surging at the spray gun, shut
off the pump, trigger the gun to relieve fluid pressure,
and open the drain valve (D) at the bottom of the surge
tank. See Fig. 3. After the tank is drained, close the
drain valve and resume operation.
1
Open drain valve to relieve pressure.

D
Be sure the drain valve is fully closed when spraying
and fully open when draining or circulating fluid to get
the best results and reduce wear on the valve.
