Two EMI mounting kits are also available (1000-0000-0101 helical mounting assembly or 1000-0000-0162 gravity mounting kit). See the
documentation that ships with the kit for mounting instructions.
3.6.1. Constructing a New Pad
Use only concrete for new pad construction. Do not use substitute
materials since they lack the rigidity for WIC placement.
Observe local building practices for pad construction. Charles
recommends that the pad should extend a minimum of 8” beyond
the WIC base on all sides.
Use a minimum of 6” of sand or gravel as a base for the pad for
leveling purposes.
Figure 7 shows the required conduit openings and mounting hole
dimensions for entering/mounting the bottom of the WIC. Use these
dimensions when designing the pad.
WARNING
When pad mounting, the compression strength
of the pad must be at least 4000 psi as
determined by ASTM C39 test of compression
strength of concrete cylinders.
The slump of the concrete shall be 2” to 4” as
determined by ASTM C143 test method.

3.6.2. Mounting the WIC on a Pad
Eight customer supplied, corrosion resistant, 3/4”Grade 8 hex head bolts with anchors are required for mounting the WIC to the concrete
pad. The WIC comes with a pair of washers for each mounting hole. Use both washers when securing the bolts. Use the following steps to
mount the WIC to a pad.
1. Layout, drill, and set the 3/4” anchors per manufacturer’s recommendations. The embedment depth is not to exceed 3.5”.
2. Clean any debris from the concrete pad.
3. Ensure that the WIC is parallel to the pad surface as it is placed onto the pad and that it aligns with the holes in the pad.
4. Place the WIC on the pad. Loosen the slings so that all the weight is on the pad. Check that the WIC is level and properly
aligned.
5. Secure the WIC to the pad using the 3/4" hex head bolts and washers (two washers per bolt). Tighten all bolts securely.
6. Once the WIC is secured, remove the slings and tagline and close the door.
3.6.3. Mounting with the EMI Helical Mounting Kit
This kit is ordered separately from EMI (part number 1000-0000-0101).
1. Assemble the universal driving tool on the correct Kelly bar adapter.
2. Connect the Kelly bar adapter to the Kelly bar on the drive head.
3. Move the drive tool assembly to the first helical and attach the universal
driving tool to the helical plate, ensuring that the Kelly bar is as centered in the
helical as possible. The leveling hardware can be used for this temporary
attachment.
4. Lift the helical upright, allowing it to swing free of the ground.
5. Maneuver the helical directly over the installation point.
6. Lower the helical until the point of the helical is forced into the ground on
target.
7. Screw the helical 12 inches into the ground and plumb using a level on two
sides at 90 degrees from each other.
8. Continue screwing the helical into the ground while correcting the Kelly bar’s
orientation so the helical embeds itself straight. A ground man can be of
assistance in keeping the foundation plumb during the installation.
9. Drive the helical until the helical plate is 11 inches above grade, oriented as
shown in Figure 8. Stop the driving tool assembly. Disconnect the universal
driving tool from the helical plate.
10. Repeat steps 3 through 9 for all helicals paying attention to helical plate orientations.
11. Install leveling hardware in the center on each helical. Each helical has one set of leveling hardware and each set of leveling
hardware consists of one threaded rod, four nuts, eight washers, and four lock washers.
12. Install the four corner plates on the leveling hardware, one in each corner.
13. Level and secure all the leveling hardware on the corner plates and helicals. The leveling hardware should not be installed outside
the 3 inch radius of the helical pipe. The corner plates have elongated holes for 2 inches of play.
14. Lift and set WIC on the Helical Foundation Kit. Be sure to bolt the WIC base to the corner plates prior to releasing all of the
weight of the WIC onto the corner plates.
15. Once all hardware is installed connecting the WIC base to all corner plates, tighten and secure all the hardware.

3.6.4. Mounting with the EMI Gravity Mounting Kit
This kit is ordered separately from EMI (part number 1000-0000-0162).
Grade Considerations:
1. Ground/gravel should be normally dry and have good drainage.
2. Ground/gravel should be level or very close.
Procedure:
1. Lift and set the WIC On The Ground (Gravity) Foundation Kit in the desired
location. The WIC On The Ground (Gravity) Foundation Kit ships assembled,
stairs separate of course, so lift and set it on grade in the desired location. If
using a forklift and the forks are not long enough to get under all three bars of
the frame, make sure the frame does not tilt over during lifting. This can be
accomplished with weight on the two bars the forks did get under, or by
removing the footers from the bar the forks did not get under. This is aimed at
safety, as the frame can withstand tilting. The weight of the frame is 300 lbs.
The weight of the footers are 31 lbs each.
2. Level the frame by adjusting the leveling hardware between the frame and the
nine footers. Be sure to maintain 18 inches from grade to the top of the frame,
which is the bottom of the WIC. Start by leveling the four corners first then adjust the remaining footers.
3. Lift and set the WIC on the WIC On The Ground (Gravity) Foundation Kit in desired location. Be sure to bolt the WIC base to
the frame prior to releasing all of the weight of the WIC on the frame.
4. Once all hardware is installed connecting the WIC base to the frame, tighten and secure the hardware.
3.6.5. Mounting with the EMI Extension Mounting Kit
This kit is ordered separately from EMI (part number D1007-0000-0012).
This kit includes four concrete pad extensions for the four corners of the WIC.
1. Set the four concrete pad extensions on the four corners of the concrete pad in
the desired locations (Figure 10).
2. Lift and set the WIC on the extensions. Ensure that the WIC is level, and bolt
the WIC base to the extensions prior to releasing all of the weight of the WIC
on the extensions.
3. Once all hardware is installed connecting the WIC base to the extensions,
tighten and secure the hardware.

-NOTE-
Changing the speed controller default factory set points can lead to system performance issues, such as equipment failures, increased power
use, unnecessary alarms, noise, condensation build up, fan failure caused by excessive runtimes and vibration.
Avoid placing items in front of the CTMS’s return and supply vents. Maintain a minimum of 2” clearance to enable proper air flow.
The CTMS is shipped with the operational parameters set at the factory.
3.7.5. IVS Operation
The DC powered IVS has an on-board controller, four ventilation fans, and six dampers leading into the WIC interior space.
The IVS is turned on in two ways. First, there is a manual timer that can be set for a maximum of one hour. A technician entering the WIC
can set this timer so that fresh air will be drawn into the WIC while work is being performed. Second, the IVS can be activated by an
internal temperature probe connected to the controller that turns the fans on when the interior temperature reaches 60⁰C. The IVS will then
draw outside air into the WIC to cool the cabinet.
3.7.6. HVAC Operation
This section only applies if the 97-WIC10KHVACKT HVAC kit has been installed on the WIC.
The HVAC system is turned on manually whenever the WIC is occupied. The 10000BTU DC powered HVAC compressor and fans are
speed controlled. The compressor turns on at 30°C, reaches its high speed at 42°C, and turns off at 27°C. The internal fan is always on to
continually circulate heat within the cabinet. The heating cycle turns on at 10°C and off at 15°C. See the label on the air conditioner for
firmware information. For further information, refer to the HVAC documentation that ships with the kit.
-NOTE-
Changing the cooling or heating cycles’ default factory set points can lead to system performance issues, such as equipment failures, increased
power use, unnecessary alarms, noise, condensation build up, compressor or fan failure caused by excessive runtimes and vibration.
Avoid placing items in front of the HVAC’s return and supply vents. Maintain a minimum of 2” clearance to enable proper air flow.
3.7.7. Fiber and Copper Entry
The WIC has two cable entry holes on the front (Ø1.5” and Ø1.0”) intended for conduit entry for the customer supplied AC load center.
The two sides and the rear each have a Ø1.06” entry hole for the ground cables.
The AC disconnect panel has three Ø7/8” knockouts intended to cable entry for the customer supplied Raycap AC disconnect. These holes
can be enlarged using a Greenlee tool to a maximum of Ø2.0”.
The upper rear corners, on the sides of the WIC, each have a sealed cable entry port for GPS cable entry.
The interior floor of the WIC has four entry ports for running cable inside from the runway space beneath the floor.
LT-WIC101010
3rd Printing
Page 13 of 16
The right side of the WIC, near the top, has two panels, each with four portals. Each portal has nine Ø0.605” entry ports athat
accommodate Ø0.5” cable.
See Figures 2, 3, and 4 for all entry locations.
3.8. Conduit Seals
All conduit openings on the WIC must be completely sealed with a duct seal compound to prevent
moisture from entering the WIC. Use a moldable, flame-retardant putty style duct seal material. Do not
use an expanding foam seal. Mold the putty so that the open space around the wire or conduit is
completely sealed, as shown in Figure 12. If the openings must be accessed at any time, remove the
putty and set it aside. When work is complete, re-mold the putty to re-seal the opening.
3.9. Verifying the Installation
Verify that earth ground and all grounding and bonding is complete and functional. After verifying that
all installer connections are secure and complete, apply voltage.
4. PERIODIC MAINTENANCE
In the event that the enclosure must be opened in freezing conditions, use a narrow, pointed metallic object such as a screwdriver or chisel,
along with a non-metallic device like a rubber mallet, to remove excessive ice buildup around the door and locking mechanism. A
commercial aerosol de-icer spray can be used to free up locks and latches if needed. Use protective gloves and safety glasses when
applying de-icer sprays.
Reset the GFCI duplex receptacle periodically to ensure it is working. The unit meets UL-943, which requires an auto-monitoring (self-
testing) feature. A flashing or solid red LED indicates a fault. If the unit continues to show a fault after resetting, replace the unit.
Refer to the CTMS manual supplied with the CTMS for periodic maintenance requirements.
