4.3 When operating soldering torch, set air pressure regulator to approximately 15 psi when using N-2 type torch tip.
Use 40 to 60 psi when using the large N-4 type torch tip.
Air pressure regulator controls both soldering torch iar pressure and air test pressure.
Most radiators are tested at approximately 15 psi, however, test pressure should be 2 or
3 lbs. above operating pressure. Test heater cores at 30 psi and air-conditioning
components at maximum pressure.
5. PREVENTATIVE MAINTENANCE
5.1 Your bench will last indefinitely if given proper maintenance. It is recommended that the tank be drained,
cleaned and refilled with fresh water once every week.
5.2 Interior Paint. The inside of the tank has been coated with radiator paint. Once a year or as needed, sand
rusted areas and recoat to prevent deterioration and to preserve an attractive appearance.
5.3 Exterior Paint. Exterior surfaces have been coated with Dark Gray Primer Surfacer and finished with abrasive
resistant paint. Clean and repaint surfaces as needed to preserve a good finish and an attractive appearance.
Always prime bare metal.
5.4 Magnesium Anode
To insure long tank life, equip the Bench with a plug-type magnesium anode. This anode installed in
the bottom of the tank retards rust and corrosion by neutralizing Muriatic Acid contamination.
Magnesium Anode will dissolve in the process of neutralizing the acid and should be
replaced when deteriorated. To replace Magnesium Anode, drain tank and remove 3/4"
pipe plug which is attached to anode. Remove and replace anode. Insert plastic
support on opposite end.
