The pump inlet air tube connects to the inlet side of the SP4
solvent pump through the inlet fitting
The yellow flush tube from the injection gun/mix head extends
down through the outlet side fitting and connects to the outlet of
the solvent pump
Note
It is important that the solvent level in the tank remain
no less than full so there is at least one inch of
solvent above the pump. This will allow the pump to
properly refill with solvent after each use.
Activate the SP4 by pressing the flush button on the control panel. The pump will operate for 30
to 60 seconds. The duration of the flush/purge cycle can be adjusted. For more information,
reference the Innovator II Control Unit component manual.
Maintenance
It is important to keep the inside of the flush tank clean and free of dirt, debris, or glass fiber.
These can prevent the pump foot valve from sealing properly.
The SP4 solvent pump is essentially maintenance free except it will occasionally be necessary to
replace the O-ring on the pump foot valve.
Optional Connections
When using an Innovator unit with one of the larger fluid sections (HO or HV), the standard 10
mm feed tube assembly can be a little restrictive and could cause the MPG to activate at higher
flow rates. It may be necessary to use one of the following options to increase the flow.
Configuration 1
This configuration uses either a
5
8
inch poly tube or a ½ inch resin hose as the feed hose. By
changing the two hex nipples on the injection head and IVx3 valve, other resin hose assemblies
can also be used. The
5
8
inch poly tube has the advantage of being translucent so the operator
can see the resin flow and check for air bubbles during an injection, as well as being less
expensive than resin hose.
Configuration 2
This is an alternative connection for the IVx3 valve using ½ inch poly tube. The nut and ferrule
style of fittings are recommended, since they will have a more positive lock on the tubing, have a
