eCool Setup
1. Remove the eCool unit from the box. Loosen but don’t
remove the four Phillips head screws attaching the cover
to the aluminum mounting plate. After the four screws are
loosened, remove the cover. Please note that the pump’s
power socket is connected to the cover, so it will need to
remain near the pump.

2. Using the slot nuts on the back of the eCool mounting plate,
mount the eCool unit to the upper t-slot on back of Shark gantry.
Tighten the Phillips head bolts to secure the mounting plate to
the gantry. Note: The eCool unit should be mounted to the X-
drive motor end of the gantry ( the right side, when facing the
back of the gantry –see image)
3. Begin opening the cable track with a flathead screwdriver.
Start a few sections in from the right so the water hoses enter
the cable track with out tight bends or kinks.

4. Once the cable track is open, run the hoses through the track. Let
the excess hose run over the top of the sign towards the front of the
machine

6. Loosely attach the spindle mount with the four new mounting
bolts. Tighten the two bolts on the right side. Slide the spindle
into the mount so it is positioned about midway, or a height that
meets your needs, then tighten the two bolts on the left side.

5. Loosen the two bolts on the left side of the mount and then remove
your router. Next remove the two bolts on the right side and remove
the mount.

Hose hookup
7. Once the spindle is
secured in the clamp,
attach the hoses from the
cooling system to the
fittings on the top of the
spindle. First remove the
nuts from the fittings on
the spindle and then slide
one onto onto the end of
each hose. Slide the
hoses onto the fittings
and tighten the nuts.
NOTE: The hose with the
flow indicator should be
attached in the location
shown in the image,
which is the supply side.
INTALLATION TIP: Warming and softening the ends of the
hoses with a heat gun makes them easier to install.

Priming the pump
8. Next fill the coolant reservoir with water or fresh propylene
glycol (RV/Marine Grade) coolant. When the reservoir appears full,
connect the eCool power cord to an active power source. The
pump should turn on and distribute the coolant into the spindle.
Repeat 2-3 times or until the reservoir remains full while powered
on. The flow indicator should be moving when the pump is primed.
When the pump is fully primed, the water level will stay constant.
NOTE: After the pump is primed, the pumps power cord should
be move to the power strip that is attached to the back of the
Shark Control Box. See page 12 for details.
9. Re-attach the eCool enclosure using the 4 screws that were
previously loosened.

10. Attach the spindle power cable to the top of the spindle. Now take
the spindle power cord from the inverter (VFD) and plug it into the top
of the spindle. There is a groove on the plug that that matches a tab on
the spindle socket. Make sure these line up when connecting the parts.

12. Attach the Spindle Interface cable to the front of the Control
Box. NOTE: Depending on where the controller is located on the
machine’s table, a power strip with a longer cord may be
required to prevent strain on the various cables. Perform a jog
test around the entire machine to ensure there is no strain.
11. Plug a power strip (not included) into the back of the Shark
controller. Then plug the VFD and eCool power cords into the
power strip. NOTE: For the eCool system and VFD to function
correctly they must be connected to the plug on the back of
the Control box via a power strip or similar multi-plug
connector.

13. Set your desired spindle speed in the tool data base for each bit you
use. This speed is saved to your .tap file and is used to automatically turn
on the spindle and adjust its speed. A speed between 16,000 and
22,000 works well for most bits, with lower speeds for large diameter
bits and higher speeds for small diameter bits. DO NOT EXCEED Router
Bit manufacturer’s RPM recommendations
14. You must save your toolpath using
the Next Wave CNC (inch)(*.tap)
post processor (shown at the right).

15. You may need to update the firmware on your Control Box and LCD
Pendant before using this spindle. If the spindle turns on when you run a
.tap file, then you have the correct firmware. If the spindle fails to turn
on, then you should update the firmware. For information on how to
update your firmware visit www.nextwavecnc.com/firmware.
To use this spindle, you
must use VCarve (Desktop
or Pro) 10.5 or higher or
Aspire 10.5 or higher.

Maintenance/Troubleshooting
The Flow indicator is not turning
•Is the Control Box turned on?
•Is the digital interface cable securely attached to the front of
the Control Box?
•Is the pump plugged into the power strip on the back of the
Control Box?
•Is the eCool powered on? Look for a blue light in the
reservoir itself.
•Are large bubbles preventing the flow indicator from
turning? Light tap or shake the indicator to dislodge the
large bubbles. Some air or bubbles are OK.
•On rare occasions the water flow may be block by air in the
spindle/. This can be resolved by first disconnecting the
power to the VFD, then remove the spindle (with the hoses
still connected). Next tip the spindle back and forth and
upside down to dislodge the air lock.
Replacing eCool system coolant
•The pump reservoir coolant level should be checked
regularly and replaced every 4-6 months.
•Unplug the eCool power supply from the power strip
connected to the controller.
•With a small bucket or container ready, remove the hose
with the flow indicator (supply side) from the spindle. It will
immediately leak so place it over the bucket
•Plug the eCool power supply into a separate outlet, this will
power the eCool system immediately.
•Let the water drain from the hose into the bucket.
•Once the eCool system is fully drained, follow the
installation steps to re-prime the pump

Maintenance/Troubleshooting
Spindle not starting
•Is your Shark controller and pendant on the latest firmware?
•Check that all cables are plugged in as specified in the
installation instructions
•Was the correct file selected in the USB screen?
NOTE: If a laser file is selected, the eCool system and
VFD will power off. To correct this, the controller will
need to be restarted to function correctly.
Collet Nut installation issues
•The collet should snap into the spindle’s collet nut with the
long-tapered part of the collet going up into the spindle
away from the collet nut. You should be able to turn the
collet nut over and the collet will hang loosely from it.
•If this is done incorrectly, the collet and collet nut can be
damaged or cross threaded
