Physical Mounting
Section titled “Physical Mounting”Location Requirements
Section titled “Location Requirements”- Considerations for location in the building:
- Typically, a centralized location of your plant works well where the unit can reach the most CNCs in the least amount of plumbing
- Locate where a coolant source (barrel, tote, etc) is easily accessible and can be changed out
- Locate where services such as water, power, and internet are established or can be
Wall Mounting Guidelines
Section titled “Wall Mounting Guidelines”- Considerations for mounting on a wall:
- Physical size and mounting are documented in our drawing section of manual
- Position top of DFU about 6 feet high on wall. We have found this height range is the best overall for any maintenance or inspections needed. Do not mount too high for suction reasons.
- DFU weighs approx. 55 pounds, make sure your chosen mounting location can accommodate this
- Mount on wall with no or very low vibration
- Consider access for plumbing
- Instal customer supplied ball valves for the water supply, water output, and coolant output ports in case of quick shut off
