TABLE 3: TROUBLE SHOOTING GUIDE
Problem
Cause
Corrective Action
Fan not spinning
Low system pressure
Low oil level in tank
Air leak in suction hose or fitting connections
Collapsed Suction Hose
Flow Control Valve has blocked orifice
Fan sucked in road trash such as a plastic bag and has caused fan to
be in a bind
The system pressure must be higher than 1000 psi for the fan to spin at
full speed. Slower fan speeds in an unloaded condition are part of normal
operation
Fill Tank, tighten fittings, and bleed air from lines
Tighten fittings and bleed air from lines
Replace suction hose
Remove and clean or replace valve. Change fluid and filter element
With Unit de-energized, remove debris, check for proper torque of hub bolts.
Check to make sure the fan is not broken or cracked and motor functions
properly
High Oil Temperature
Dirty Heat Exchanger Assembly
System Relief Valve is opening
low oil level in tank
Collapsed Suction Hose
Air leak in suction hose or fitting connections
Clean Heat Exchanger. Use mild cleaner compatible with aluminum. Be
careful not to damage fins when using a pressure washer.
Ensure that valve relief pressure is set higher than your system pressure.
Remove and clean or replace valve. Change fluid and filter element
Fill Tank and tighten fittings
Replace suction hose
Bleed air and tighten fittings
Aeration of oil
(Milky looking oil)
Water Contamination
Air leak in suction hose or fitting connections
Pump is not lower than the tank
Restricted suction line
low oil level in tank
Replace Fluid and Filter Element. Check all fittings and Filter Cap for tightness
Tighten fittings and bleed air from lines
Reposition to ensure the fluid can gravity feed into the pump through the
suction line.
Route suction line to make as straight and short of a run as possible. Ideally
you would want a 2.5” suction line for minimum flow restriction.
Fill Tank and tighten fittings, verify proper fill level before use
Heat exchanger
Assembly leaks
Loose Fittings or cut o-rings
Burst Heat Exchanger
Replace o-rings and tighten fittings
Replace Cold start relief valve and Heat exchanger assembly
