If pressure switch wires are damaged then they will need to be repaired or replaced,
as this will cause issues between the control board and the pressure switch.
If pressure switch wires are damaged, this will affect
how the control board interacts with the switch. IF
wires are damaged, repair/replace (Field Supplied). IF
not damaged, replace main control PCB (HPXMCB50).
Attach high pressure manifold gauge. IF during
operation the pressure exceeds 580PSI, go to step 3E. IF
it does not exceed 580PSI, replace pressure switch
(HPX2001-3605).
Inspect Pressure Switch Wires
Step 3C
Step 3D
Verify High Pressure Side
NOTE: A pressure gauge adaptor (1/4” male SAE to 5/16”
female SAE) must be field supplied to test the high and
low pressure manifolds.
