Initial Operation Check; Ambient Operating Temperature - Speedaire 40HU29 Instructions Manual

Initial Operation Check

Important: Check motor rotation before operating the compressor.
After confirming the correct direction of rotation for the main motor and cooler fan, the compressor is ready to run
for an operation check.
With a valve installed at the outlet of the tank, close the valve and isolate the tank from any pipeline system so
only the compressor tank will fill up with compressed air.
1. Turning the compressor on. Confirm position of E-stop.
2. Press the ON / OFF button. The compressor will start.
3. Allow the compressor to run for approximately 5 minutes. The pressure in the tank will rise as the compressor
runs.
The following will take place:
a. When first turned on the air end will build up internal pressure prior to sending air into the tank. This may
take 15-20 seconds. You may notice a slight change in the sound when the minimum pressure valve
opens inside the air end allowing air to flow into the tank.
b. Air pressure in the tank will rise until the pre-set maximum pressure is reached. Upon reaching the
maximum pressure the compressor will turn off.
Do not remove air filter housing or perform any maintenance with pressure in the
air end or air pressure tank.
c. While the compressor is running look and listen for any leaks with which may have developed during
shipping and handling.
RISK OF BURNS! Surfaces and parts will become hot.
4. Allow compressor to run for approximately 5 minutes. Turn off using the ON / OFF button. Allow compressor
to sit for at least 1 minute while the high pressure air is released through the compressor inlet. You will hear
the air escaping.
Disconnect, tag and lock out power source then release all pressure from the
system before attempting to install, service, relocate or perform any maintenance.
5. Release all air pressure from the tank prior to performing any maintenance or restarting the compressor for
the next run sequence in item #8.
6. Allow the compressor to cool, and then check the oil level. Add oil if needed.
7. Seal any air or oil leaks if needed.
8. Restart air compressor. Turn on main power. Press ON / OFF button and the compressor will start.
9. With valve at the tank outlet closed the air pressure will build in the tank to the cut-out pressure. Air pressure
in the tank will rise until the pre-set maximum pressure is reached. Upon reaching the maximum pressure the
compressor will switch off.
10. Release pressure from the tank down to the cut-in pressure and the compressor will automatically restart.
Pressure will build in the tank until it reaches the cut-out pressure and stop again.
When the pressure in the tank drops to the cut-in pressure the unit will turn on and the air inlet valve will open
allowing the air to be compressed and re-fill the tank.
This sequence of operation will continue until the ON/OFF switch is turned to the off position.
Your compressor is now ready for use.
NotE: All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as necessary for the intended application.
Failure to install appropriate water / oil removal equipment may result in damage
to machinery or workpiece.

Ambient Operating Temperature

The compressor is designed to operate in an ambient temperature between 40° F and 100° F. At ambient
temperatures below 40° F, the unit must be heated up to at least 70° F before start-up.
