Enclosure Exhaust - Introduction

Templates

Some machines do not have the necessary cutout. For these machines, use this template.

On the top of the machine enclosure, measure the dimensions [A] from the front of the machine and [B] from the right side of the machine. Mark the center [C]:
  • A - 9.5" (24.1 cm).
  • B - 8.5" (21.6 cm).
note: For larger machines, be sure to put the cutout nearer to the work area.
Measure the dimensions [D], [E], and [F]:
  • D - Ø6.50" (16.5 cm).
  • E - Ø9.843" (25.0 cm).
  • F - 4X Ø0.375" (9.5 mm).
Cut the (1) large hole [D] and the (4) small holes [F].
note: For an HMC, make the cutout above the machine enclosure, behind the operator's door.

Enclosure Exhaust - Installation

Step 1

Remove the cover plate [1] from the top of the machine enclosure. If the machine does not have 4 mounting holes drilled, refer to the provided template and drill the remaining holes

Lathe models ST-40 and larger [3] have two layers of sheet metal on the ceiling of the machine. Remove the bottom cover [5] in the machine. Remove the cover [6] on the top of the machine.

Put the ENCLOSURE EXHAUST [A] on the top of the machine enclosure.

note: Make sure the Haas logo on the ENCLOSURE EXHAUST [A] points to the front of the machine. This position gives the best access to the filters [7] in the ENCLOSURE EXHAUST [A].

Install the (4) WASHER [D] and the (4) NUT [E] to the standoffs for the ENCLOSURE EXHAUST [A]. For lathe models ST-40 and larger [3], install the (4) WASHERS [D] and the (4) NUTS [E] between the two layers of sheet metal.

Step 2

Install the cable [1] from the ENCLOSURE EXHAUST [A] to the control cabinet.

Install the (4) CABLE TIE CLAMP [F] to the top of the enclosure.

Use (4) CABLE TIES [G] to attach the cable [1] to the CABLE TIE CLAMP [F].

Step 3

For machines that have the Next Generation Control:

Disconnect the spindle fan cable [1] from P32 on the I/O PCB.

Connect the 3-pin connector [2] of the cable [3] from the ENCLOSURE EXHAUST [A] to P32 on the I/O PCB.

Connect the spindle fan cable [1] to the 3-pin female connector [4] of the cable [3].

Find the 2-pin connector [5] that has the label ENCLOSURE VAC SWITCH on the cable [3]. Connect that connector [5] to the 2-pin connector [6] from P34 on the I/O PCB.

Step 4

For a VMC or a lathe that has the Classic Haas Control:

Disconnect the 300A cable [1] from P41 on the I/O PCB.

Connect the 3-pin connector [2] of the cable [3] from the ENCLOSURE EXHAUST [A] to P41 on the I/O PCB.

Connect the 300A cable [1] to the 3-pin connector [4].

Connect the 8-pin connector [5] to P23 on the I/O PCB.

Step 5

For an EC-400/500 that has the Classic Haas Control:

Disconnect the 300A [1] cable from P41 on the I/O PCB.

Connect the 3-pin connector [2] of the cable [3] from the ENCLOSURE EXHAUST [A] to P41 on the I/O PCB.

Connect the 300A cable [1] to the 3-pin connector [4] of the cable [3].

Disconnect the cable labeled VAC SW [C] (not shown) from the cable [3].

Connect the 2-pin connector [5] of the cable [3] to the 2-pin connector [6] from P23 on the I/O PCB.

Step 6

The ENCLOSURE EXHAUST [A] operates with the spindle.

It starts when the spindle fan starts. It stops a short time after the spindle fan stops.

Conclusion

Do not discard the filters [1] in the ENCLOSURE EXHAUST [A] when they are dirty. Remove the filters [1] and clean them. Use a solution of soap and water.

The ENCLOSURE EXHAUST [A] has a 10" diameter duct connection. This lets you add optional ducting [2] to the shop duct system. The kit does not include ducting.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
