Start-up Preparation
1. Inspect the filter bags. Inspect the secondary
filter cartridge if operating at 40K.
2. Check the tightness of the gland nuts on each
stuffing box.
3. Inspect all equipment. Ensure that every piece
of equipment in the pressure circuit is properly
rated for the intended operating pressure. Re-
place any component that is not properly rated.
4. Connect the supply hose and verify the drain
valve is closed.
5. Open the water supply valve and allow the tank
to fill. Any valves between the water tank and
the pump must be open.
6. Install the discharge hose onto the fitting on the
manifold along with a hose safety check.
7. Open the bypass valve by turning the knob
fully counter-clockwise until the O-ring is visible
(where the knob enters the valve body) or four
full turns counter-clockwise from the closed
position. This allows the engine to start without
a load from the pump.
WARNING
!
Anytime the system has been opened, the
system must be purged.
When the high pressure hose is first connected
to the unit or when extra hose lengths are added
to the hose string, the hose must be purged of all
dirt and debris. Do not connect the control gun or
tool to the high pressure hose until the hose has
been purged of dirt and debris with water flow
from the pump. Failure to purge debris inside
a hose may result in clogging of the cleaning
nozzle and excess pressure in the system.
