MAINTENANCE
FLUSHING
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 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.
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: A good flow of water must be flowing
from the end of a gun within 30 seconds, before
proceeding. Lack of water can cause water
pump damage.
CAUTION: DO NOT RUN PUMP WITHOUT
WATER, AS THIS WILL CAUSE DAMAGE TO
THE PUMP AND VOID WARRANTY.
CAUTION: On a machine equipped with a
trigger gun valve, if the trigger gun valve
remains in the closed position for more than 5
minutes, water pump damage may occur.
8. When clean water flows from the gun, turn
switch to the OFF position.
9. Disconnect the water supply.
10. Dissconnect the electrical supply.
11. If freezing conditions may exist, refer to
“STORAGE” section.
STORAGE
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. Check the position of the ball valve (if so
equipped) on the outlet of the float tank
assuring it is in the closed position.
3. 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 Then turn switch to the BURNER
position and depress the vacuum switch. Run
it for 45 seconds allowing any remaining water
to turn to steam. Allow air to blow for 60
seconds. Turn switch to the OFF position.
4. 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. FLOAT TANK EQUIPPED: Pour the anti-freeze
solution into the float tank.
7. WITHOUT FLOAT TANK: Install a 2-ft.
Garden hose to the water inlet. Insert the other
end into a container of antifreeze solution.
8. Turn on the switch to the PUMP position.
9. Turn off the switch just prior to running out
of antifreeze mixture.
10. Disconnect electrical supply.
11. Fill the fuel tank with kerosene or #1 or #2
diesel.
12. It is recommended to install a coil cover to keep
coil free of debris
13. Drain the float tank.
14. Place machine in a dry place protected from
weather conditions
SPRAY TIP MAINTENANCE
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 MODEL
EXPLODED VIEW.
