INSTALLATION AND LOCATION
OPERATION
1. Installation:
2. Electrical connection:
Install the compressor in a covered, well
ventilated area, free of dust, toxic gases, humidity or any
other kind of pollution. The compressor should be located no
closer than 32" (800mm) from a wall or any other obstacle
that could interfere with the air flow through the fan. This
distance will also make maintenance easier. Place the
compressor on a leveled surface. Rotation of the flywheel
must be in the direction of the arrow cast into the flywheel.
The maximum ambient temperature recommended while
working is 113ºF or 45ºC. If necessary, install an exhaust fan
to guarantee fresh air and to dissipate heat.
Before making the electrical connections, check oil level and
top-up lubricating oil. For type of oil, see table at the end of
these instructions.
The country's valid electrical
standards must be followed regarding Low Voltage Electrical
Installation.
Before turning on the compressor,
check the crankcase oil level. It must be between the
dipstick's maximum and minimum marks, or in the middle of
the OIL LEVEL SIGHT. As to the type of oil to be used and the
recommended change intervals, check at "Lubrication" and
as to its volume, check the Technical Data Table.
Turn on the electrical start key and let your
compressor run for about 10 (ten) minutes, what will keep
the tank's internal pressure or compressed air around 20
psig. This will optimize a homogeneous lubrication of the
parts.

Turn off power before servicing and be sure the air tank is unloaded. These
instructions are based on normal operating conditions. If the compressor is
located in an exceedingly dusty area, increase the frequency of all
inspections.
Inspect the compressor visually.
Check oil level and add some if necessary, before turning the
compressor 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 allow
approximately 3/8" to 1/2" (9 to 13 mm) deflection with normal thumb
pressure.
Clean cylinders externally, cylinder head, motor, fan blade, tubing, and tank.
Safety valve should be tested manually to see if it is working properly.
Check entire system for air leakage around fittings, etc by using water and
soap 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 cap screws and nuts as required.
- Change oil more frequently if compressor is located in a very dirty
environment.
- On the 7 ½, 10 and 15 HP compressor pumps, the concentric valves must be
inspected and cleaned between 800 and 1000 service hours.
Test and calibrate the pressure switch, pressure gauge and safety valve
according to their own technical standards. These parts must be removed
from the tank and pump to be tested.
Inspect and clean the suction and discharge valve(s) plate(s) every 1000 (one
thousand) working hours (whichever occurs first), located between the
cylinder and its cover and, if necessary, replace it (them) according to the
operation 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 of
operation, or 60 (sixty) days, whichever occurs first.
Heavy Duty and multi-viscous oils are not adequate for Schulz air
compressor's lubrication. The same applies to oils that tend to emulsify.
We recommend good industrial oil for air compressors, with rust and
oxidation inhibitors and high viscosity level (from 90 to 95), SAE or ISO, as
indicated in the table below:
- WHILE RUNNING IN A PERIOD OF ABOUT 100 WORKING HOURS THE OIL
LEVEL SHOULD BE CAREFULLY CHECKED.
