Project support

Every floor is laid out from its own dimensions, temperatures and electrical service. Send the basics and we return a layout and the details your electrician needs.

01What to send

Floor plan with dimensions, door openings, dock pits, columns and drains
Room design temperature, and any areas held at different temperatures
Slab, insulation and base construction, or the architectural section
Available electrical service: voltage and phase
Preferred control panel location and distance to the floor
For existing floors: age, history, any heave or temperature readings

Tip

Floor dimensions and room temperature are enough to start. Your local representative can run a preliminary layout with you.

02What we provide

Floor layout drawing with conduit locations, spacing and dimensions
Electrical details: circuits, cable runs per circuit, running and inrush current, service required
Control and monitoring wiring details, with wire types and maximum lengths
Control panel schematic with terminal details
Installation and startup instructions and a detailed checkout form
Replacement parts list with standard, off-the-shelf part numbers
Phone support during installation, startup and troubleshooting

Typical layout drawing for a 52 by 58 foot freezer showing conduit loops, junction boxes, control panel HT-1, circuit and monitor notes — **Fig. 1**Example layout drawing: 52.5′ × 58′ freezer at 28 °F, 240 V 3-phase, three circuits with seven cable runs, end-run monitors and three thermocouples.

03Installation sequence

ConduitPrepare the subgrade. Set the conduit loops and capped sensor conduits per the layout. Cap all open ends.
Base and floorPlace the aggregate or mud slab, then the vapor barrier, insulation and slab. Protect risers during the pour.
Boxes and cableMount the junction boxes. Pull cable through each loop. Install power connection and end seal kits. Install sensors.
Wiring and checkoutWire power, monitor and sensor circuits to the panel. Perform the checkout below. Seal conduit entries.

04Startup checkout

When the cable and connections for a circuit are complete:

Inspect the cable. If it is damaged, replace the full length; no splices are made inside conduit.
Check each connection kit: correctly assembled, moisture seal in place at every cable entry, caps installed.
Test insulation resistance at the power connection with a 500 VDC megohmmeter (or the voltage the cable manufacturer specifies). Remove any cable reading less than 10 MΩ.
Energize and record voltage at the end of each circuit. Confirm each end-of-run relay operates.
Record the current on each cable at startup and again after 30 minutes. Keep these values for preventive maintenance.
Test every alarm: low temperature, sensor break, ground fault, circuit fault, horn, beacon and remote contacts. Record the results on the checkout form.

Repeat the insulation resistance and current readings during periodic maintenance and compare them with the startup record.
