This chapter of the manual provides details about how to install the Haas Air Compressor - 15HP. This chapter gives information about pre-installation precautions, installation requirements, and electrical installation requirements for both the fixed speed and variable speed versions.

Move the air compressor as close to it's installation location as possible before removing the compressor from the protective packaging. To make it easier to move the compressor, leave it secured to the pallet.

When ready to install the compressor, unfasten the feet from the pallet. Each foot connected to the storage tank has a bolt [1] fastened to the pallet as shown in the image.

The image shows the recommended ventilation and minimum spacing requirements needed for a compressor to run efficiently.

• At least 3 ft (1 meter) [1] spacing between compressors and between the sides of the compressors and any walls as shown in the image.
• The compressor needs to be in an area with a ceiling clearance of at least 8.2 ft (2.5 meters) [2].
• At least 3 ft (1 meter) [3] of spacing from any walls in the front or back of the compressor so that it can be easily serviced.

When determining the location of the compressor, there needs to be at least 3 ft (1m) of open space on the right side [1] of the compressor.

Note: This is so that the oil discharge port [2] and oil intake [3] can be easily accessed when performing oil changes.

 Important: The air compressor will come with oil inside the oil reservoir. The oil that is supplied with the air compressor is for the first maintenance oil change. The compressor does not need to be filled with oil at install.

Route the black airlines [1] connected to the oil-water separators [2] to a discharge container [6].

Important: The red ball valves [3] located on the oil-water separators need to be manually opened weekly to drain the water. The drain valves need to be fully closed when the air compressor is being used.

Route the airlines coming from the separators to the manifold [4] that is connected to the timer valve [5]. Route the output line [7] of the manifold to a discharge container [6]. See section 3.1 Operation for details on configuring the timer drain.

Connect an airline to the outlet of the compressed air filter [1] shown in the image.

Note: The thread for the male fitting needed to connect the airline to the filter is defined on the label on the filter cannister [2].

The thread type for HAC15-FS and HAC15-VS compressors is an RC-3/4" thread [2].

Warning: The compressor must have a ground connection when connecting it to the power supply. Connecting the compressor to the power supply is dangerous and should be done by qualified personnel only.

To connect the air compressor to power, make sure that the appropriate power supply is being used.

Verify that the incoming voltage meets the electrical specifications for the air compressor listed on the specification plate. Compressors can be 220VAC / 3Phase or 380VAC / 3Phase.

Note: The specification plate shown in the image is for 380 VAC [1] since it is the European version. Compressors in the United States are made for 220 VAC but check the specification plate to confirm before you connect the incoming power.

Feed the power supply pigtail extension cable to the electrical cabinet through the enclosure panel located on the left side of the main compressor unit behind the compressed air dryer. 

Note: The power cable port is shown in the image. There is a decal labeled "Power Inlet" [1] to help locate where to feed the cable through the enclosure [2].

Remove the rear enclosure panel to gain access to the electrical cabinet. The electrical cabinet has a pane of safety glass that needs to be removed in order to access the electrical terminals.

Unfasten the wingnuts [1] securing the safety glass in position.

Remove the glass and feed the power supply extension cable through the side port.

WARNING: Do not make electrical connections with the extension cable plugged into the power supply source. Make sure the line is disconnected before making the connections outlined in the next step.

Variable Speed Wiring:

After feeding the pigtail through the power inlet port [1] connect the L1 [2], L2 [3], and L3 [4] lines of the power supply pigtail cable to the respective terminals of the electrical cabinet.

Once you have verified these lines are securely connected and the ground wire [5] is also installed, connect the pigtail cable to the power supply source cable.

Note: This image shows where to make the electrical connections on a variable speed air compressor. See the next step for the electrical connections on a single speed compressor.

Single Speed Wiring:

Feed the power pigtail through the power inlet port. Then make the connections to the power pigtail.

Note: The wiring is the same as it is for the variable speed compressor in the previous step. The location of the electrical terminals is different between the compressors.

Connect L1 [1] L2 [2] L3 [3] and the ground [4] from the incoming power supply pigtail to the terminal.

Once connections on the terminal are made and verified, connect the pigtail to the power supply.

This chapter of the manual provides details about how to install the Haas Air Compressor - 30HP. This chapter gives information about pre-installation precautions, installation requirements, and electrical installation requirements for both the fixed speed and variable speed versions.

Route the black airlines [1] connected to the oil-water separators [2] to a discharge container [6].

Leave the ball valve at the bottom of the tank open always. This only needs to be closed when performing maintenance on the mesh filter right after the ball valve.

Important: The red ball valves [3] located on the oil-water separators need to be manually opened weekly to drain the water. The drain valves need to be fully closed when the air compressor is being used.
