Figure 4-7 shows the approximate location of the plumbing connections.
The connection for the for the Spindle
Coolant Make-Up Water is 1” NPT. The
water source can be provided from clean
ordinary tap water.
The connection for the for the Process
Coolant Make-Up Water is 1” NPT. This
water source can be from water deionized
by another source or from clean ordinary
tap water.
The connection for the Spindle Cooling
Supply is 1-1/4” NPT. This provides water
cooled by refrigeration to cool the spindle
motors. This is a “closed-circuit” loop circuit
and does not require a lift station.
The connection for the Spindle Cooling
Return is 1” NPT. This connection directs
return water from the spindle cooling loop
back to the reservoir.
The connection for the Process Cooling Supply is 1-1/4” NPT. This provides water
filtered, de-ionized
2
and cooled by refrigeration to cool the cutting, grinding or
dicing process. This process is normally “open-loop”. Therefore, a separate “Lift
Station” is required to return the water back to the WFS. The customer is
responsible to collect and direct the process water to the lift station pump.
The connection for the Process Cooling Return is 1-1/4” NPT. This connection directs
return water from the Lift Station back to the reservoir.

Electrical Hook-Up
The unit requires three (3) phase 220 VAC 60 Hz 40 Amp or 230 VAC 50 Hz 40 Amp
power with grounding wire.

Deionization is accomplished by customer supplied resin tanks.
