Coolant Chiller - Installation

1

VF-1/2/3/4/5

Secure the drill template to the enclosure in the location specified by the diagram. Use 5/16 drill bit to make holes using template.

Note:  For VF-2YT that have a stiffener on back panel use a spacer and longer bolts to mount.

For all models except those stated below, place drill template on right side [4] of the stiffener otherwise for the models stated below place on left side [3].

  • VF-3YT/50
  • VF-5/50XT
  • VF-5/50TR
  • VF-5/50

2

Align the upper bracket [1] with the upper three holes drilled in the enclosure panel using the template.

Raise the left side window and install the coolant chiller upper bracket [1] onto the enclosure panel using the sealing washers [2] and machine screws [3]. Do not fully tighten the machine screws.  Make sure the position of the upper bracket can still be adjusted by hand. 

 Note: For VM-2, VF-2YT and VF-2SSYT equipped with SMTC-50 and built before 01/2020. These machines have a stiffener [4] on the back panel that require a spacers.  Install the spacers [5] (P/N 59-1822) in between the back panel and the upper bracket.  Install the longer screws (P/N 40-1978) and washers (P/N 45-0184).

Do not fully tighten the machine screws.  Make sure the position of the upper bracket can still be adjusted by hand. 

 

3

Electrical Safety

Caution: When maintenance or repair is performed on CNC machines and their components, you must always follow basic safety precautions. This decreases the risk of injury and mechanical damage.

Push [POWER OFF].

Set the main circuit breaker to the [OFF] position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Danger: Before beginning any work inside the control cabinet the High Voltage indicator light on the 320V Power Supply / Vector Drive must be off for at least 5 minutes. If the voltage indicator light is on, do not touch the electrical components. The high voltage in the electrical cabinet can kill you. Some service procedures can be dangerous or life threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about performing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.
