Construction & Materials
- The FD-5 features a double-walled cabin lined with Grade-A Western Red Cedar — naturally antimicrobial and aromatic — and a Thermal Plus™ Aspen exterior that will never rot, warp, or decay. The walls are insulated for maximum heat retention and energy efficiency. Its 8mm tempered glass door provides durability and a clean aesthetic.
Installation
The FD-5 is designed for indoor use only and fits under standard ceilings. It assembles in 60 minutes with two people. Infrared system plugs into a 240V outlet using the included NEMA 6-15 plug. If using a traditional heater (optional), a hardwired 240V / 20A circuit is required. Panels lock together via pre-fitted hardware, and the bench system installs tool-free. Adjustable leveling feet included.
Operation & Usage
Once plugged in, use the touchscreen or app to power on, set temperature (up to 170°F), and choose session duration (up to 60 minutes). Red light therapy is built in. Preheat time is ~20–30 minutes depending on ambient temperature. No plumbing or venting needed. The large two-level bench system allows flexible seating for 1–4 people.
EMF & Safety
The FD-5 is built with safety at its core:
- Ultra-low EMF output, third-party tested
- ETL certified to UL/CSA electrical safety standards
- Built-in overheat protection and session timer
- Zero off-gassing materials or adhesives
- Ideal for daily use in residential settings.
