Hand Drilling of Mix Modules
16 310648P
Drill Bit Table
When drilling, be careful not to allow bit to come
in contact with ID of mix module.
The largest drill size that can be used on the
XF1313 mix module is #56. To get more flow,
order a larger mix module: XF3535, XF4747,
XF5757
6.
Reassemble gun, page 34.
7.
Check pressure gauges. A (ISO) and B (RES)
gauges should balance at the required pressure,
flow, and temperature operation points.
8.
If ISO gauge still reads lower than the RESIN,
repeat steps 1 through 7. Use the next drill bit size
for drilling the B (RES) port on the mix module.
9.
If you get the system pressure balanced but do not
have enough flow at the gun, drilling port A (ISO)
may be necessary. Drill port A (ISO) out to next
size. Repeat steps 1 through 8 to bring the pres-
sure gauges back into balance.
10.
Repeat drilling until system pressures are bal-
anced.
11.
After system pressures are balanced, record the
final drill bit sizes for each port in the chart
below. Use this information when it is time to
replace the Polycarballoy Mix Module.
