Optional Air Conditioner Installation and Operation
See Figure 3-13 and Figure 3-14. An optional air conditioner that mounts on top of the
console is available for field installation. The air conditioner requires 200−250 Vac, 50/60
Hz. Refer to
Miscellaneous Kits
in the
Parts
section for the AC kit part number.
WARNING: Shut down the iControl 2 system and disconnect power at a disconnect
switch ahead of the console before installing the air conditioner kit.
1. Shut down the iControl 2 system and disconnect power.
2. Open the console door and disconnect the small fan mounted on the top cover from
the top left iFlow module by either cutting the wires or removing the plug and pushing
the pins out.
3. Disconnect the ground strap from the top cover plate.
4. Remove the top cover plate and gasket from the console. Keep the M5 serrated nuts
for re-use.
5. Remove the plug, conduit seal, and conduit nut from the top/right corner of the back
wall of the console.
6. Remove the 3/8 NPT plug from the coupling at the bottom inside of the console and
install the two barbed fittings into the coupling, one on top and one on the underside.
7. Install the terminal block on the studs located in the upper right inside corner of the
console back wall, using the two M5 nuts.
8. Install the new cover plate and gasket on top of the console, using the M5 serrated
nuts removed in step 4. The plate can be rotated 180 degrees as desired to change
the orientation of the A/C unit. The two slots in the cover plate must match up with the
center opening and the two outlet vents in the bottom of the A/C unit.
9. Connect the console ground strap to the closest ground stud on the new cover plate.
10. Install the A/C unit on the new cover plate according to the manufacturer’s
instructions, using the fasteners provided with the unit.
11. Install the drain kit provided with the air conditioner according to the manufacturer’s
instructions. Terminate the drain tubing on the upper barbed fitting installed in step 2.
Connect tubing (customer-supplied) from the lower barbed fitting to a floor drain.
12. Connect the A/C power cord to the terminal block as shown.
13. Route the AC power cord through a dust-tight cord grip or conduit connector into the
console and connect it to the terminal block as shown.
14. Use the wiring harness included in the kit to connect the terminal block relay to the
iControl 2 400W power supply as shown. This prevents the A/C unit from running
unless the iControl 2 console is turned on.
Filter: To clean the AC unit intake filter, remove the screw from the grille and slide the
grille up.
