7. Allow time for air to purge from pump system and return to
tank
8. Close bypass/agitation valve completely to pressurize system
9. Adjust pressure to desired level with adjusting cap
10. Squeeze trigger to clear hose of air and begin spraying. note
pressure while spraying.
11. Adjust regulator to no more than 10-15 psi higher than spray
pressure. Excess pressure will drain battery unnecessarily.
12. When initial star-up is completed:
Push On-Off switch to OFF position
Rotate Power Selector to “OFF” to avoid accidental
operation or unnecessary batery drain
13. Empty tank of water
Read and understand the many features of battery charger.
Refer to enclosed battery charger information for more details
regarding settings and features.
PUMP OPERATIng InSTRUCTIOnS FOR SYSTEMS
Each Pumptec system is tested and inspected prior to shipment
from our facility in Minnesota. This routine includes setting
the pressure to optimum performance levels. Only though
tampering or extremes during shipment should a unit need
pressure adjustment upon arrival to end-user. If you see
shipping issues call Pumptec Inc at 763.433.0303 immediately.
We recommend that you perform an initial set up and test of
your system with clean water to check for leaks. DO nOT install
chemicals before completely testing pumping module and all
connections.
Note: AlWAYS flush and rinse system after every use. nEVER
change chemicals without completely rinsing tank and whole
pumping system. AlWAYS read chemical label and exactly
follow recommendations for system flushing.
1. Check your water and chemical supply, and then check the
supply in the tank.
2. Do you have adequate filtration? Check line strainer/filter
to make sure it is clean and free of debris.
3. If it is necessary to disassemble the filter to inspect r clean,
be certain to seat the gasket properly, along with the screen
and tighten extra firmly. Any air leakage at the point will
cause drop in pressure and loss of pump prime. It may be
necessary to lubricate gasket prior to re-assembly.
4. Check all plumbing connections to make sure they are tight
5. Check your power source. Make sure your power source is
connected correctly
6. To prime your pump open prime valve on regulator
7. Start pump ( pull on-off switch out) and allow air to purge
from system which usually takes 5-15 seconds
Note: The pressure may be factor set as a result of the
water/chemical flow restriction to the OEM system. Changing
tips or guns will affect system performance.
8. Hold trigger open on spray gun and start pump. Allow all air
to purge from system and liquid to spray. Trigger the spray
gun a few times to check pressure and nozzle function.
If you are pleased with the spraying pressure and nozzle
performance you will nOT need to make any adjustments.
9. With spray gun triggered, you can adjust the spraying
pressure by adjusting the regulator valve.
Note: nEVER adjust to a back pressure greater than machine
rating.
There are two easy ways to lower your pressure:
• Turn the regulator knob counter clockwise
• Change to larger size nozzle tip and then adjust the regulator
to 5-10 psi above spray pressure
Note: The opposite of either will raise the pressure to
maximum pressure setting of the regulator.
10. Adjust the nozzle tip on the gun supplied
Note: higher pressure requires more amperage. Use only the
pressure you need. Do not unnecessarily overload system.
Should the system overload, a breaker will trip resulting in a
