6.
Remove spray tip from gun assembly.
7. With the gun assembly in hand (on trigger gun models
hold the trigger gun valve in open position) and with a
good flow of water turn switch to the PUMP position
CAUTION:
DO NOT RUN PUMP WITHOUT WATER,
AS THIS WILL CAUSE DAMAGE TO THE PUMP AND
VOID WARRANTY.
8. When clean water flows from the gun, turn switch to
the “OFF” position. Reinstall spray tip.
10. With the gun assembly in hand turn on the switch. On
trigger gun models hold the trigger gun valve in open
position.)
11. When clean water flows from gun, turn switch off the
PUMP position
11. If freezing conditions may exist, refer to “STORAGE”
section.
13. Turn off and disconnect the water supply. Disconnect
elctrical supply.
1.
Rinse the chemical line by inserting the screen into a
container of clear water and open the metering valve 1
minute to clean it of any remaining residue. Be sure
the chemical metering valve is closed when finished.
2.
Disconnect the water supply. Remove the spray tip
nozzle from gun assembly and wire to machine.
3.
Check the position of the ball valve (if so equipped) on
the outlet of the float tank assuring it is in the closed
position.
4.
Attach an air chuck to the air valve stem on the pump
assembly. With the trigger gun in the open position,
apply air until a mixture of air and very little water is
coming from the gun wand . Allow air to blow for 60
seconds. Turn switch to the “OFF” position. Remove
the air chuck.
5.
Fill a 1-gallon container with Ethylene Glycol type
antifreeze. Minimum should be a mixture of ½ antifreeze
and ½ water strength before each use, as the antifreeze
will dilute with use.
6. Install a 2-ft garden hose to the water inlet. Insert the
other end into a container of antifreeze solution.
7. With the gun assembly in hand turn on the switch. On
trigger gun models hold the trigger gun valve in open
position.)
8.
Turn off the switch just prior to running out of antifreeze
mixture.
9.
Disconnect electrical supply, and the gun and hose.
10. Place machine in a dry place protected from weather
conditions.
1.
Correct belt tension will allow a 1/64- inch deflection
for each inch of span between pulley centers with a
6-pound force applied in the middle of the span.
EXAMPLE: A 6-pound force applied at the middle of
an 8 inch span should produce a deflection of 8/64
inch or 1/8 inch.
2.
Belts can be tightened or loosened by loosening the
nuts holding the pump assembly to the motor mount.
Then tighten or loosen the j-bolt on the motor mount.
Retighten the pump assembly after the desired
tension is reached.
1.
Remove the spray tip from the gun assembly.
2.
Blow out debris with compressed air from the outside
in. Any debris remaining in the inlet side of the nozzle
should be cleaned out. If lime or chemical scale is
present in the inlet side, the nozzle may be soaked
in descaling solution or replaced. If the tip is worn,
replace with one specified in the GENERAL section
of
MODEL
SPECIFICATIONS
or

.
3.
Before replacing spray tip flush the machine per
“FLUSHING”.
4.
Reinstall Spray tip to gun assembly.
1.
Connect machine to an electrically grounded circuit
that is fuse or circuit breaker protected.
2.
Connect machine to a pressurized water supply
meeting the requirements specified in the GENERAL
section of the
MODEL
SPECIFICATIONS
.
3.
Turn on the water supply.
4.
Check the float tank (if so equipped) to assure it is
full and the float valve shuts off securely.
5.
Check the position of the ball valve (if so equipped)
on outlet line of the float tank assuring it is in the
open position.
