PRE-STARTUP CHECK LIST
Failure to disconnect and lockout
electrical power or engine drive before
attempting maintenance can cause
severe personal injury or death
Hazardous
machinery can
cause serious
personal injury.
Failure to properly leak test the
compressor installation may result in
leakage of explosive gas to the
atmosphere creating an explosion
hazard, possibly causing severe
personal injury or death.
Hazardous gases
can cause property
damage, personal
injury or death
Discharge piping surface temperatures
may be hot during operation (over
158°F, 70°C). Temperatures should be
monitored and adequate warnings
posted.
Extreme Heat can
cause personal injury
or property damage
1. After the compressor is installed in the system, a
complete leak test MUST be performed on both the
compressor and the piping.
2. Re-check the system piping and the piping supports
to ensure that no piping loads are being placed on
the compressor.
3. If V-belt driven, check the alignment of the motor and
the compressor sheaves. The faces of the sheaves
must be parallel.
4. Ensure that pressure gauges are installed on both
inlet and discharge of the compressor.
5. Blackmer compressors are shipped from the factory
without oil in the crankcase. Fill with a high quality
non-detergent oil of the proper viscosity via the
compressor nameplate opening. See "Crankcase
Lubrication" in this manual.
6. Check the electrical connections for proper wiring,
grounding, etc.
7. With the power disconnected, remove the
compressor crankcase cover. Squirt oil onto each
crosshead while rotating the compressor by hand to
verify smooth operation.
8. Ensure that all guarding is properly installed.
Operation without guards in place can
cause serious personal injury, major
property damage or death.
Hazardous
machinery can
cause serious
personal injury.
Flywheel guard contact with moving
parts may be a source of ignition in
explosive atmospheres causing severe
personal injury or death
Hazardous gases
can cause property
damage, personal
injury or death
STARTUP PROCEDURE
NOTICE:
Consult the 'Troubleshooting' section of this manual
if difficulties during startup are experienced.
1. Start the compressor. Oil pressure should register
50 psig (3.45 bar-g) within 10 seconds.
If proper oil pressure is not present, stop the
compressor and correct the problem.
Operation of the compressor with low or
no oil may result in extreme
temperature in the crankcase. This
could be an ignition source in the
presence of explosive gas and could
lead to severe personal injury or death.
Hazardous gases
can cause property
damage, personal
injury or death
Operating the compressor with low oil pressure will
cause severe damage to the unit. See "Setting the
Oil Pressure" in this manual.
The oil pump on these models will operate in either
direction of crankshaft rotation.
2. Verify that the suction and discharge pressures are
within the expected ranges.
Operating limits listed in the "Compressor Data"
section must not be exceeded.
3. Check for leakage from the piping and equipment,
and repair as necessary.
4. On newly rebuilt units, the valve cover bolts, adaptor
bolts, and cylinder head bolts MUST have their
torque checked after 60 minutes running time. Also
re-tighten all hold down bolts, flywheel bolts, etc.
after 60 minutes running time. See Table 4 - "Bolt
Torque."
