1. Quick Reference Electrical Specification Matrix

The Saunum Air Perfect series is engineered for seamless architectural integration, recessing into or behind the sauna benches while routing equalized air through hidden ducts.

2. Critical Electrician Directives & Code Mandates

Code Mandate

Licensed Electrician & Safety Directive

Concealed Pathway Code Requirement: Because the Air Perfect integrates behind benches and wall cladding, all electrical rough-in conduit must be rigid or liquid-tight flexible metal conduit properly secured to framing prior to closing walls and installing bench platforms.

A. Supply Conductor Standards & Conduit Entry

  • Conductor Material: Copper conductors only, rated minimum 90°C (194°F) (THHN/THWN).
  • Conduit Rough-In: Terminate wiring through the bottom knockout on the lower tower service tray.
  • Neutral Conductor: The heater elements run on straight 240V (L1, L2, and Ground). Verify whether the AirIQ main module requires a 120V neutral feed to power its electronic control logic and Wi-Fi interface.

B. GFCI Breaker Policy

  • Manufacturer Recommendation: Connect to a dedicated standard 2-pole thermal-magnetic breaker without GFCI. Standard Class A GFCI breakers (4–6 mA) are prone to nuisance tripping during startup due to minor atmospheric moisture absorption in the large stone bank, which evaporates within 1 hour of heating.

3. Clearances & Spatial Layout (Safety Distances)

Table 2: Minimum Safety Clearances to Combustibles

Parameter Saunum Air Perfect 7 Saunum Air Perfect 10
Minimum Distance to Side Wall 4.0 in (100 mm) 4.0 in (100 mm)
Minimum Distance to Rear Wall 2.0 in (50 mm) 2.0 in (50 mm)
Minimum Clearance to Ceiling 4.0 in (100 mm) above top air intake 4.0 in (100 mm) above top air intake
Minimum Clearance to Front Bench 4.0 in (100 mm) 4.0 in (100 mm)

4. Mounting & Sauna Kit Timber Construction

The dry weight of the Air Perfect is 147 lbs (67 kg). When loaded with 210 lbs of stones, total weight is ~360 lbs (163 kg).

A. Pre-Fabricated Solid Timber Sauna Kits (Dundalk Leisurecraft & SaunaLife)

Pro Rough-In Advisory

Pre-Manufactured Solid Timber Kit Structural Directives

Kit Owners & Installers Reassurance: If installing Saunum Air Perfect into an EpicSauna pre-manufactured solid timber kit:

  • Floor-Standing Base: The weight of the heater rests on the heavy-duty 1.5"+ solid cedar or spruce floor timbers.
  • Upper Wall Anti-Tip Bracket: The top of the circulation duct includes a wall-securing bracket that screws directly into the solid timber wall staves using the supplied lag screws. No cedar cladding anchors or internal stud blocking are required.

Frequently Asked Questions (Electrician & Rough-In Knowledge Base)

What makes the Saunum Air Perfect different from the standard Saunum Air?

The Air Perfect is specifically engineered for integrated, behind-bench or semi-recessed installations. While the standard Saunum Air is an exposed pillar heater, the Air Perfect hides behind the benches with sleek flush air grilles for a minimalist, clean aesthetic.

What breaker size is needed for Saunum Air Perfect 10?

The Air Perfect 10 draws 41.25 Amps at 240V. Per the user manual and NEC rules, it requires an 8 AWG copper wire and a 50 Amp 2-pole circuit breaker.
