MAINTENANCE
Prior to each batch:
• Make a general inspection of the unit for defects or unusual conditions. Do not use the unit with any defects or
if in doubt about any conditions.
• Clean up any spills immediately upon occurrence.
• Remove any slop or build-up within the heating vessel.
• Lubricate the metal to metal seal of the heating vessel and lid with petroleum jelly.
• Check that debris is picked up and not allowed to accumulate around the unit. Be sure that debris is not
allowed to restrict air flow through the condenser fins.
• Use a short, low pressure blast (25 psi) of compressed air into one of the clean solvent outlet tubes, while the
unit is empty and the lid is off and air is restricted through the other clean solvent outlet tube. Use proper eye
protection. There should be no restriction of air flow between the clean solvent outlet tube and the hole(s) on
the walls inside the heating vessel. Repeat with the other clean solvent outlet tube. Do not use the unit if there
are any obstructions.
Routine weekly:
• Check the safety relief valve. Use a short, low pressure blast (5 psi) of compressed air into one of the clean
solvent outlet tubes, while the unit is empty and the lid is in place and while air is restricted through the other
clean solvent outlet tube, it should relieve pressure at less than 5 psi. If not, remove and clean or replace the
safety relief valve. Be careful excess pressure can cause damage. Always use proper eye protection.
• Clean the condenser fins using a wire brush and a blast of compressed air. Always use proper eye protection.
• Make a general inspection of the unit for defects or unusual conditions. Do not use the unit with any defects or
if in doubt about any conditions.
Routine monthly:
• Disconnect from power, remove the access panel on the units left side (opposite the outlet tubes, your right
facing the front logo panel) and carefully wipe any accumulation of dirt and debris that may have accumulated
on the fan blades.
• Make a general inspection of the unit for defects or unusual conditions. Do not use the unit with any defects or
if in doubt about any conditions.
