Dymax SG-200 High-Flow Spray Gun System User Guide
Connecting the SG-200 spray valve to the Control Valves
1.
When using the Ram Pump setup, the
“material in” line used in ot
her configurations will be used to supply
air to the Ram pump manifold. Open regulator completely, or if supplying air to Ram Pump from outside
line, plug port with push-fit plug.
2.
Connect factory air to air filter regulator. Be sure regulator outlet knob is in “off” position.
3.
Turn on air filter regulator, and pressurize initially to 20 psi. Check for leaks and be sure all fittings are
secure.
Connecting the Material Lines to Valve
The material regulator comes preinstalled on the ram pump. These instructions can be used when replacing
the material regulator.
1.
Disconnect the air supply from the ram pump.
2.
Connect the ¾" FNPT x 1/2" MNPT pipe adapter directly to the material outlet port on the ram pump.
3.
Connect the ½" FNPT x 3/8" MNPT adapter.
4.
Directly connect downstream regulator to the 3/8" MNPT adapter. Ensure the regulator material flow
direction is correct.
5.
Connect high-pressure hose to material outlet side of regulator
6.
Connect the free end of the high-pressure hose to the material whip supplied with the SG-200. Ensure all
connections are tight.
NOTE:
Use Teflon®/sealant tape on all straight connector and fitting threads. For best performance, keep
the hose lengths as short as possible and ensure tight connections between fittings.
Priming the Ram Pump
1.
Connect the air supply to ram pump. Adjust the initial pressure settings on the ram pump manifold to 30-
40 psi.
2.
Check that the ram pump is tightly assembled, lubricated, and oiled before use.
3.
Raise the head until
it’s
fully in the up position.
4.
Ensure that the proper head is on the ram pump (straight pail vs. tapered pail).
5.
Follow the Ram Pump Operator
’s
Manual for lowering/priming material into the ram and bleeding the
piston.
Note: When ram head is lowered to material level, relieve ram head actuation pressure to zero.
Gravity & pressure “pulls” the ram down as material is d
ispensed.
6.
Remove the nozzle, collar, and atomizing cap from the SG-200 spray gun.
7.
Turn on the air supply to the ram pump, DVC-345 controller, and spray gun atomizing regulator stand.
Ensure all control valves & regulators turned off.
8.
Turn the controller on and set to manual mode for priming.
