Installation
Air Connections
See FIG. 1, FIG. 2, or FIG. 3.
1.Connect 5/32 in. (4 mm) OD air tubes from the valve solenoids to the air inlets of each valve.
2.ProMix 2KS and ProMix 3KS systems only: Connect an air supply line to air purge valve (APV) inlet (1/4 in. ID tube is supplied, with tag).
3.Pressurize the system with air, and check for leaks, then relieve air pressure.
Fluid Connections
See FIG. 1, FIG. 2, or FIG. 3.
1.Connect the solvent supply line to the 1/4 npt(f) sol- vent purge valve (SPV) inlet.
2.Connect the component A supply line to the meter A (MA) 1/4 npt(f) inlet.
3.Connect the component B supply line to the meter B (MB) 1/4 npt(f) inlet.
4.ProMix 3KS systems only: Connect the component C supply line to the meter C (MC) 1/4 npt(f) inlet.
5.Connect the gun fluid supply line between the static mixer tube (SM) and the gun fluid inlet.
NOTE: On ProMix 3KS systems only, connect the fluid hose (supplied with your system) between the ProMix 2KS static mixer and the fluid inlet of the ProMix 3KS. Then connect the gun hose to the static mixer of the ProMix 3KS.
Installation
Grounding
The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.
Connect a ground wire from a true earth ground to the mix manifold or the mix manifold mounting surface if there is electrical continuity between it and the mix man- ifold.
Follow the specific grounding instructions in the system and individual component manuals. The system may have special grounding requirements for the mix mani- fold.
A ground wire and clamp, part no. 223547, is available from Graco.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid con- taminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See Purging, page 7.
