INSTALLATION AND LOCATION
OPERATION
1. Installation:
2. Electrical connection:
Install the compressor in a covered, wellventilated area, free of dust, toxic gases, humidity or anyother kind of pollution. The compressor should be located nocloser than 32" (800mm) from a wall or any other obstaclethat could interfere with the air flow through the fan. Thisdistance will also make maintenance easier. Place thecompressor on a leveled surface. Rotation of the flywheelmust be in the direction of the arrow cast into the flywheel.The maximum ambient temperature recommended whileworking is 104ºF or 40ºC. If necessary, install an exhaust fanto guarantee fresh air and to dissipate heat.
Before making the electrical connections, check oil level andtop-up lubricating oil. For type of oil, see table at the end ofthese instructions.
The country's valid electricalstandards must be followed regarding Low Voltage ElectricalInstallation.
Before turning on the compressor,check the crankcase oil level. It must be in the middle of theOIL LEVEL SIGHT or OIL LEVEL DISPSTICK. As to the type ofoil to be used and the recommended change intervals, checkat "Lubrication" and as to its volume, check the Technical DataTable.
Turn on the electrical start key and let yourcompressor run for about 10 (ten) minutes, what will keepthe tank's internal pressure or compressed air around 20psig. This will optimize a homogeneous lubrication of theparts.

Turn off power before servicing and be sure the air tank is unloaded. Theseinstructions are based on normal operating conditions. If the compressor islocated in an exceedingly dusty area, increase the frequency of allinspections.
Inspect the compressor visually.
Check oil level and add some if necessary, before turning thecompressor on.
Drain moisture from the piping system.
Be sure there is no excessive or unusual vibration or noise.
Remove and clean intake air filters; do not wash the filter element.
Check V-belts for tightness. Belt tension should be adjusted to allowapproximately 3/8" to 1/2" (9 to 13 mm) deflection with normal thumbpressure.
Clean cylinders externally, cylinder head, motor, fan blade, tubing, and tank.
afety valve should be tested manually to see if it is working properly.
Check entire system for air leakage around fittings, etc by using water andsoap lather.
Check the pressure switch operation.
Check for oil contamination and change it if necessary.
Change the air filter element every 300 working hours or quarterly.(Whichever occurs first).
Fasten bolts and nuts as required (see Table 1).
- Change oil more frequently if compressor is located in a very dirtyenvironment.
Test and calibrate the pressure switch, pressure gauge, pilot valve,discharge valve and ASME safety valve according to their own technicalstandards. These parts must be removed from the tank and pump to betested.
Inspect and clean the suction and discharge valve(s) plate(s) every 1000 (onethousand) working hours (whichever occurs first), located between thecylinder and its cover and, if necessary, replace it (them) according to theoperation conditions.
- The first oil change should be made after 8 hours of operation.
- The second oil change after 40 hours of operation.
- The third and following exchanges should be made after 200 hours ofoperation, or 60 (sixty) days, whichever occurs first.
Heavy Duty and multi-viscous oils are not adequate for Schulz aircompressor's lubrication. The same applies to oils that tend to emulsify.
We recommend good industrial oil for air compressors, with rust andoxidation inhibitors and high viscosity level (from 90 to 95), SAE or ISO, asindicated in the table below:
- WHILE RUNNING IN A PERIOD OF ABOUT 100 WORKING HOURS THE OILLEVEL SHOULD BE CAREFULLY CHECKED.
