Concealed Service Layout Scope
The layout should show the concealed valve assembly, water connections,
controller, power components, sensor wiring and accessible service zone
within the wall or adjacent enclosure. Components should be arranged so
normal inspection, commissioning and replacement can be completed without
unnecessary removal of permanent finishes. Only verified manufacturer
dimensions should be used in final construction documents.
Complete Service Layout
Show all concealed plumbing, electronic and power components
together with their service-access relationship in one coordinated view.
Concealed Valve Position
Locate the valve where water connections remain accessible
for inspection and future replacement.
Controller Position
Mount the electronic controller in a dry, protected and
serviceable location within approved cable reach.
Power Component Location
Locate the approved power component where it can be inspected
and serviced without disturbing plumbing connections.
Sensor Cable Route
Route low-voltage sensor wiring from the faucet to the
controller without sharp bends or contact with moving hardware.
Valve-Control Cable
Show the electrical connection between the controller and
water-control valve with connectors remaining accessible.
Water Supply Route
Show the 1/2-inch NPT supply path to the concealed faucet
assembly without unnecessary bends or mechanical stress.
Isolation Access
Provide accessible isolation so the faucet can be serviced
without shutting down unrelated plumbing fixtures.
Connection Clearance
Maintain sufficient working space around threaded and
electrical connections for inspection and servicing.
Front Service Zone
Provide a clear working area in front of concealed components
so they can be reached through the normal access opening.
Vertical Service Clearance
Reserve sufficient vertical space to disconnect, remove or
replace concealed components without obstruction.
Horizontal Service Clearance
Maintain adequate side clearance for tools, connectors and
component withdrawal during maintenance.
Access Panel Position
Where an access panel is required, align it with the primary
serviceable components rather than offsetting it unnecessarily.
Access Panel Size
Provide an opening large enough to inspect and remove the
valve, controller and associated connections.
Wall Cavity Clearance
Keep concealed components clear of studs, blocking and
adjacent building services.
Moisture Separation
Keep electronic components away from plumbing joints and
locations where leakage or standing moisture may occur.
Cable Support
Support wiring so it does not hang against sharp metal edges,
plumbing lines or removable access panels.
Connector Visibility
Keep electrical connectors visible and reachable for diagnostic
testing and future component replacement.
Pipe Separation
Arrange concealed components so cables and electronic modules
do not rest directly against water piping.
Drain Conflict Clearance
Where nearby drainage is present, maintain access to both
the faucet components and drain connections.
Support Surface
Provide suitable mounting surfaces for the valve, controller
and cable-support components.
Component Labeling
Identify concealed components clearly so maintenance personnel
can distinguish valve, controller, power and sensor connections.
Removal Path
Maintain an unobstructed path so serviceable components can
be withdrawn through the access opening.
Finished Service Layout
Show the completed concealed arrangement with all components
organized, supported and accessible for future maintenance.
Engineering note:
Service-access dimensions must not be based on estimated product measurements.
Confirm valve size, controller dimensions, cable reach, power configuration,
connection requirements and required maintenance clearance from the approved
FontanaShowers specification sheet or project submittal before wall fabrication.
Required Service Access Views
Front Service Elevation
Show the concealed valve, controller, power component,
connections and primary service-access zone.
Side Wall Section
Show component depth, wall cavity, access opening and
required working clearance.
Concealed Component Plan
Show the valve, controller, power source and cable routes
within the available cavity.
Access Panel Detail
Show the opening size and position relative to the serviceable
components behind the wall.
Plumbing Connection View
Show supply piping, valve connection and accessible isolation
points.
Electrical Connection View
Show sensor, controller, valve-control and power connections
with accessible connectors.
Maintenance Clearance View
Show the minimum working area required to inspect and remove
concealed components.
Finished Service Layout
Show the final coordinated installation after plumbing,
electrical and wall components are complete.
Recommended Service Layout Sequence
1. Review Approved Submittals
Confirm final valve, controller, power and connection
requirements before locating concealed components.
2. Establish Access Zone
Reserve the required service area before framing and finish
work restrict available space.
3. Coordinate Wall Cavity
Check studs, blocking, piping and adjacent services for
potential conflicts.
4. Position Valve
Mount the concealed valve where water connections remain
accessible for inspection.
5. Position Controller
Mount the electronic controller in a dry location within
the approved cable-routing zone.
6. Locate Power Component
Provide the selected power arrangement where it remains
reachable and separated from potential leakage points.
7. Connect Water Supply
Complete the plumbing connections while maintaining adequate
clearance for tools and future service.
8. Route Cables
Support and organize sensor and valve-control wiring away
from sharp edges and plumbing joints.
9. Verify Removal Paths
Confirm major serviceable components can be removed through
the planned access opening.
10. Pressure Test
Test plumbing connections before permanent wall finishes
restrict access.
11. Complete Access Panel
Install the required removable access provision while
maintaining the planned working clearances.
12. Final Service Inspection
Verify valve, controller, wiring and connections remain
accessible after construction is complete.
Architectural and MEP Coordination
Wall Coordination
Coordinate wall framing and finish assemblies with the
required concealed equipment and service zone.
Structural Coordination
Provide suitable support surfaces without blocking access
to valve or control components.
Plumbing Coordination
Maintain access to water connections, isolation points and
the concealed valve assembly.
Electrical Coordination
Provide accessible and protected locations for controller,
power and low-voltage connections.
Finish Coordination
Avoid permanent finish conditions that prevent normal
removal of concealed service components.
Access Panel Coordination
Locate access provisions where they serve the actual
component arrangement rather than an assumed centerline.
Moisture Coordination
Keep electronic equipment away from probable leak paths,
wet zones and standing water.
Maintenance Coordination
Retain sufficient working space for inspection, diagnostics
and component replacement throughout the fixture lifecycle.

Project verification:
This concealed-component and service-access resource is intended for coordination
and does not replace an approved project submittal. The architect, plumbing
engineer, electrical engineer, interior designer and licensed installer should
verify final component dimensions, valve location, controller position, cable
reach, power configuration, access-panel requirements, maintenance clearance
and locally adopted codes before fabrication or installation.
