OPERATING INSTRUCTIONS
Begin operation by filling tank with liquid. Next, open the ball valve (A)
and the ball valve (B) in the agitation line. Open the AA171 Tee valve
(#19) and the by-pass valve (C). Start the pump. To regulate pressure,
slowly close valve (C) until the desire pressure is attained. If adequate
spraying pressure cannot be reached, slowly close the agitation valve (B)
until the desire spraying pressure is reached.
NOTE: Roller pumps will wear after normal use and a drop in pressure
can be expected. Simply reset the by-pass valve (C) to get the pressure
back to normal.
NOTE: Each jet agitator in the tank requires a minimum of 3 GPM.
Some roller pumps are limited in their capacity to spray and agitate at
the same time.
Please order replacement parts by PART NO. and DESCRIPTION.
