Hose Electrical Resistance
Check electrical resistance of hoses regularly. If total
resistance to ground exceeds 29 megohms, replace
hose immediately.
Filters
Once a week check, clean, and replace (if needed) the
following filters.
•
Both pump filters; see your Xtreme lower pump
manual for instructions.
•
Spray gun handle filter; see your spray gun manual.
Seals
Once a week, check and tighten throat seals on both
pumps (see table for torque specifications). Follow the
to tightening seals. There must be zero pressure on the
pumps when adjusting.
Cleaning Procedure
1. Ensure all equipment is grounded. See
,
2. Ensure the area where the system will be cleaned is
well ventilated and remove all ignition sources.

6. Clean the external surfaces only using a rag soaked
in solvent that is compatible with the spray material
and surfaces being cleaned.
7. Allow enough time for the solvent to dry before
using the system.
Change the Mix Ratio
In order to change the mix ratio, one or both pumps
need to be replaced, the air motor needs to be
re-positioned, and the over pressure relief valves may
need to be changed.
1. Check the
table on page 10 for the correct
pump sizes.
2. Remove and replace pump. See
3. Adjust the position of the air motor. See
Recirculation Manifold with Over Pressure
Relief Valves
4.
If changing from one type of XPs-hf system to
another (for example - changing from XP50s-hf
to XP70s-hf or from XP70s-hf to XP50s-hf):
Remove the existing over pressure relief
valves (702) and install the correct valves for the
new system type. See
Recirculation Manifold Replacement Table
5. Change the
XP-hf Motor Air Pressure Relief
as required, depending on the ratio. See
