NORDIC PUMP SYSTEMS G4 User manual

Open top of mixing tube, check if it is clean. Also make sure mixing bin is DRY. If wet then dry before using.
Connect power –400/230V If using a generator make sure it is at least 20kva. Check switch inside electrical
cabinet to make sure it is on the correct voltage in relation to power supply.
Connect water to the G4. ¾” hose is the best but you can also use ½”. Turn on water.
G4 water connector, connect water from water supply here
Close all the water release valves on the G4, they are the ones leaking water when the water was turned on. If
nothing was leaking water then valves were already closed. Check water pressure. Needs to be at least 2.5 lbs, if
lower than 2.5 then need a water booster pump if one is not built into this particular machine. If pressure falls
below 2.5lbs then machine will shut off.
Water release valves

Open Water tap on the G4 and let all the air out of the water system. Close tap when done.
Water tap
Connect water hose coming from Volume measuring tube to TOP water connector on mixing tube.
Top water connector
Take off the water cap from the LOWER water connector on the mixing tube.
Turn on RED main power switch on the G4. Press GREEN start button to activate controls. If using 400V then check
to make sure electricity is going in the correct direction, if YELLOW light is on then it is in reverse. Simply turn main
power switch in opposite direction. If using 230V does not matter which direction it is running.
Main power switch
Manual water button
Push the manual water button on control panel while adjusting water volume to desired level. REMEMBER
STARTING WETTER IS MUCH BETTER THAN TOO DRY. When desired level is reached release button, let water drain
out of the lower water connector. When water stops coming out replace cap. Your machine is now primed.

Water volume adjuster knob
Check mortar bin to make sure it is still dry. Add 2 bags of DRY mix. Put a bucket in front of ROTOR STATOR nozzle
to catch the mixed mortar.
Rotor Stator nozzle
Turn on conveyor wheel first. Turn on pump motor switch to the right. Check mortar mixture in bucket. Adjust
water volume to get desired consistency. When consistency is correct turn off pump motor and conveyor wheel.
Mixture is ready.
Pump motor switch / Conveyor wheel switch
Rinse mortar hose with water. Empty out all water from hose. Connect mortar hose to ROTOR STATOR nozzle.
Connect end spraying nozzle. Connect one end of air hose to air nozzle on G4. Connect the other end to the
spraying nozzle. If the G4 doesn’t have its own compressor then connect a compressor to the G4. Needs
minimum 400L per minute compressor.
Turn on compressor

Compressor power button
Turn on compressor switch on the G4
Compressor on switch
Turn on conveyor wheel
Turn on pump motor. You are ready to go. To start spraying turn the air switch on at the end of the spraying
nozzle. To adjust spraying width adjust air tube at the end of the spraying nozzle.
Check pressure in mortar hose on the pressure gauge which is on the Rotor Stator nozzle. Should be MAX 1 bar of
pressure per meter of mortar hose.
If Amps are too high machine will turn itself off. If machine turns itself off then mix is too dry, hose is plugged,
speed is too fast, wrong mixing product or hose is too long.
To adjust mixture again simply adjust water volume in small amounts. Give it a minute to go through the hose
before you see the new mixture consistency.
If no power try pushing Green button again. A safety stop was probably triggered.
If Red light is on call us.

Turn off pump switch when its only water coming out.
Pump switch
Turn off air compressor
Open air nozzle at end of hose then disconnect air hose. Use very rough brush to clean out end of air tube at the
end of spraying nozzle. Clean with soapy water.
Rough brush

Check pressure in mortar hose. Pressure should be zero. If pressure is not zero then run machine in reverse for a
few seconds until pressure is zero. When pressure is zero disconnect mortar hose.
Mortar hose pressure gage
Disconnect spraying nozzle and clean with water.
Insert 2 small orange cleaning balls into end of mortar hose. Connect mortar hose to water outlet on G4 with
special hose adapter. Turn on water until small balls come out other end of hose. Do it two times. Hose is now
clean. Disconnect mortar hose.
Special hose adapter
G4 water outlet
Connect water hose to water outlet on G4. Open top of mixing tube and rinse thoroughly. Close top. Push GREEN
start button, turn on pump motor and run machine for a few seconds to clean out water in mixing tube. Turn off
pump motor when done.
Open top of mixing tube again. Remove mixing blade and replace with cleaning tool. Close top, push GREEN
start button and run machine a few seconds to clean inside of tube. Make sure water is on. Open top of tube
and check to see if clean. If not repeat process again. If you open the mixing tube you must push GREEN start
button again to activate controls.

Mixing shaft cleaning tool
Replace mixing blade.
Open lower water cap on mixing tube and clean with water.
Turn off main RED power switch. Clean dry mortar bin. Remove top grill and clean with water. Remove dust cover
and clean. Remove conveyor wheel and clean. Remove bottom drain valve under dry bin and clean inside bin
with water, draining all water out when done. Replace everything when done.
Clean outside of machine with soapy water and brush. Rinse.
Open mixing tube and clean with water one more time. Close lid.
Turn off water on G4. Turn on main RED power switch. Push GREEN power button, turn on pump motor and run
machine for a few seconds draining all water out of machine. When water stops coming out the Rotor/Stator
then shut off. DO NOT RUN TOO LONG WITH NO WATER IT WILL BURN UP THE ROTOR/STATOR!
Water should stop coming out here
Clean out the end of the ROTOR/STATOR by spraying the inside out with water.
Turn off main RED power switch. Unplug the machine.
Disconnect water from machine. Drain all 3 water release valves and leave open.
