User Manual: Rotomolded Portable Spray Units | English
READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT
Model No.: SP-20N, SP-20NK, SP-20NV
Operation Instructions
Wearing all PPE and observing all safety precautions dictated by
the MSDS for your chemical:
1.
Fill the tank with the solution to be sprayed.
2. Connect an appropriate compressed air line into the air
inlet fitting (AP25).
3. Squeeze the discharge trigger gun (PSG12) to begin
spraying.
After Use Instructions:
1.
Flush the unit with fresh water for 5 minutes.
2.
Disconnect the air line from the air fitting (AP25) and
relieve any pressure remaining in the system by squeezing
the discharge trigger gun (PSG12).
3.
Release the discharge trigger gun (PSG12) after all
pressure has been relieved from the system.
Maintenance Instructions:
To keep your portable unit operating properly, periodically
perform the following maintenance procedures:
•
Check the air pump (P56/P56K/P56V) for wear and leaks.
• Inspect hoses for leaks or excessive wear. Make sure all
hose clamps are in good condition and properly secured.
• Replace filter (AFR25) in regulator (R25) as needed.
• Check the suction tube and screen for debris and clean as
needed.
•
Drain compressor tank on a regular basis to ensure proper
operation of pump.
Troubleshooting Instructions:
•
Check to ensure that the discharge hose is uncoiled
properly, and that there are no kinks that could obstruct
fluid flow.
• Check the air regulator bowl (ABR25) and air filter (AFR25)
for debris such as water, oil, or rust particles. Clean by
unthreading the air regulator bowl (ABR25) from the air
regulator (R25).
• Check the strainer (STR38-IL) for debris or other
blockages, and clean as needed. Replace strainer if
damaged. Strainer must be used.
• If air passes through the pump (P56/P56K/P56V) without
cycling, the pump needs to be replaced.
•
Check for proper air pressure on the air gauge (AG100).
The air regulator (R25) is factory set at 50 psi (3.4 bar).
Operating range is 40 to 80 PSI (3 to 5 bar) with 2 CFM
(56.6 l/min).
• If the unit operates at a reduced pressure:
• Check the air compressor supplying the unit. If the
pressure is less than 40 psi, turn the unit off until the
compressor can catch up.
• If the air supply is 50 psi (4.14 bar) or above, check
the air gauge (AG100), which should read near 50 psi
(4.14 bar). If the air gauge reads more or less than 50
psi (4.14 bar), adjust the pressure by turning the knob
on the top of the air regulator (R25).
