Site Planning
Careful planning for the layout of the site will help eliminate possible problems with the start-up of
your system and will ensure continued, reliable system operation.
Determine the site layout.
Prepare to have all the necessary tools and parts.
All permanent wiring connections must be installed by a licensed electrician that must comply
with local and national codes.
Determine the Location
The following are a few primary concerns to consider when determining the site layout:
The Tunnel Master® wbc must be securely mounted on a dry, non-corrosive interior wall or
surface in the equipment room of the car wash.
The unit has been designed to operate in an environment of 32° F to 122° F (0°C to 50°C).
The unit is 130 lbs., 32’’ W × 40’’ H × 12’’ D with a hinged-panel door. Hinges are on the right. The
door swings open from left to right.
A minimum of 48 inches of clearance is recommended. This clearance should be available both
in front of the door and on the wall to the right of the unit. This minimum will give enough
clearance for the door to swing out and be fully opened without interfering with entrances and
exits from the equipment room.
The WBC box must be located so that conduit connections can be easily made and the relays
can be readily accessed.
Recommended minimum mounting height of 32’’ off ground to the bottom of the WBC box.
Installer shall first follow any local codes which supersede this recommendation.
Planning for Installation
Wiring can be contained in rigid PVC conduit or metal conduit.
High-voltage (AC) and low-voltage (DC) must not be combined in a common conduit, junction
box, or wire trough.
Power for the Tunnel Master® wbc and any peripherals must come from the dedicated UPS, as
supplied by ICS.
The Tunnel Master® wbc and peripheral equipment must be properly grounded.
