Specifications

Technical Specification: Electrical Supply

CRITICAL: NOTICE TO THE PROPERTY OWNER

Owner’s Brief for the Holl's Moon 4-Person Sauna

The Moon 4-Person Sauna has a total power draw of 4620W (Approx. 20.1 Amps). This unit cannot be plugged into a standard domestic 3-pin wall socket. It requires a dedicated, hardwired electrical feed installed by a qualified professional.

Mandatory Action: You must appoint a Registered Electrician to install a dedicated circuit from your consumer unit (fuse box) to the sauna location before the unit arrives.

1. Power Infrastructure Requirements

Due to the massive array of 12 Carbon panels and 4 Quartz heaters, the electrical supply must be robust and permanent.

• Circuit Specification: We recommend a dedicated 32A radial circuit using 6mm² cable (subject to cable run length and electrician's assessment).
• Isolation Switch: A 32A double-pole rotary isolation switch should be installed within the room, allowing the sauna to be fully de-energized for maintenance.
• No Standard Plugs: Attempting to modify this unit to run on a 13A plug will result in an immediate fire hazard and will void all warranties.

2. Safety & Protection

• RCD Protection: The circuit must be protected by a 30mA RCD (Residual Current Device) at the consumer unit.
• Continuous Load: Unlike household appliances that cycle on and off, the Moon 4 draws 20A consistently for up to an hour. The wiring must be rated for this sustained thermal load.
• Earthing: Correct bonding and earthing are vital for a high-wattage wooden enclosure. Your electrician must verify the earth loop impedance at the installation site.

3. Smart Features & Connectivity

The "Smart Control Hub" in the roof manages the 16-heater array and requires a stable digital environment:

• WiFi (2.4 GHz): Necessary for remote pre-heating via the smartphone app.
• Signal Penetration: Given the large Ø 180 cm size, the central control box is deep within the structure. If your router is far away, we recommend a WiFi booster to ensure the touchscreen and app remain synced.
• Bluetooth: The integrated audio system pairs with your devices. Ensure the 32A feed is clean and properly earthed to avoid any "hum" or interference in the speakers.

4. Component Layout

• Feed Location: The electrical entry point is located on the roof panel. Your electrician should leave enough "tail" on the hardwired cable to allow for the final connection once the 196cm tall panels are standing.
• Heat Clearance: Ensure the isolation switch is accessible but not directly in the path of the door when opened.

Delivery & Installation Protocol: Holl’s Moon 4-Person

HL-MOON4-BLK | Ensuring a Successful Installation

The Moon 4-Person model is a flagship wellness suite. Due to its expansive Ø 180 cm footprint and the weight of the reinforced 8mm glass and hemlock panels, the delivery and setup phase requires careful planning and coordination.

1. Universal Receipt Protocol (Mandatory)

To protect your 10-year warranty, these steps must be followed by every owner upon arrival:

• The 24-Hour Inspection Rule: You must unbox and inspect the 8mm tempered glass door and the Black Hemlock panels within 24 hours of delivery.
• Damage Reporting: Any transit damage or cosmetic marks must be reported to the retailer within this 24-hour window. Once assembly has commenced, the unit is deemed accepted in its current condition.
• Storage: All components must be stored in a dry, heated indoor environment. Do not store the panels in a garage or outbuilding, as moisture can cause the large-scale circular panels to warp, making the "Fast-Click" alignment impossible.

2. Choosing Your Installation Pathway

Pathway A: Professional Installation (Highly Recommended)

Given the size (Ø 180 cm) and the technical electrical requirements of this model, we strongly recommend our professional installation service.

• The Service: Our specialist team will move the oversized panels to your room of choice, assemble the circular structure, and perform a full commissioning of the 16-heater array (4 Quartz / 12 Carbon).
• Your Requirement: You must ensure the installation site is clear, and the floor is 100% level before the team arrives.

Pathway B: Self-Assembly (Minimum 3-4 Person Task)

• The Manpower: This is a heavy-duty build. You will need a minimum of three to four capable adults to safely position the 180cm curved wall sections and lower the roof panel into place.
• Precision levelling: A spirit level is mandatory. With a 180cm span, any floor deviation will be significantly amplified. If the base is not perfectly level, the wall panels will not meet, and the heavy 8mm glass door will not align with the magnetic seals.
• Handling: Use extreme care when handling the black-finished exterior to avoid scuffs during the manoeuvring of the large panels.

3. Technical Commissioning (First Use)

• WiFi & App Sync: Once the unit is powered, sync the control hub to your 2.4 GHz WiFi. This allows you to manage the 4.6kW heating system remotely, so the large cabin is up to temperature before you enter.
• The "Burn-in" Session: Run the sauna at its maximum temperature for 45 minutes while empty. This settles the 12 carbon panels and 4 Quartz heaters and seasons the Abachi wood interior.

Installation Readiness Checklist

• Inspection: Glass and black wood panels checked within 24 hours of delivery?
• Floor: Surface verified as 100% level with a spirit level across the full 180cm span?
•  Access: Have you measured hallways and doors for the Ø 180 cm panels? (These are significantly larger than standard door widths.
• Power: Have you reviewed the 4620W Electrical Brief and consulted an electrician?
• Network: Is there a strong 2.4 GHz WiFi signal at the installation site?

Holl’s Moon 4-Person Sauna: Warranty Statement

HL-MOON4-BLK | Flagship Protection & Maintenance Terms

The Holl’s Moon 4-Person model represents the pinnacle of the Moon series. To protect your investment and maintain the validity of your 10-year structural and 2-year electronic coverage, the following standards must be met.

1. Warranty Duration

Holl’s (Poolstar) provides a tiered warranty that reflects the professional grade of the materials used in the 4-person flagship:

• Wood Structure: 10-Year Warranty against manufacturing defects, structural failure, or major warping of the FSC-certified Hemlock and Abachi wood.
• Electronics & Heaters: 2-Year Warranty covering the 4 Quartz Full Spectrum heaters, 12 Carbon panels, the 32A-rated Control Hub, Bluetooth audio, and LED Chromotherapy systems.
• Usage: These terms apply strictly to private domestic home installations.

2. Conditions for Validity

To ensure your warranty remains active, the installation environment and technical setup must adhere to these rules:

• Professional Electrical Install: Due to the 4620W draw, the unit must be hardwired to a dedicated 32A circuit. Any damage to the control hub or heaters caused by attempted connection to a standard 13A plug or the use of extension leads will void the 2-year electrical warranty.
• Indoor Environment: The Moon 4 is designed for indoor use only. It must be located in a dry, ventilated, and heated room. Installation in uninsulated garden buildings, damp garages, or near open water (pools/showers) will void the warranty.
• Structural Precision: Given the large Ø 180 cm span, the base must be 100% level. Stress damage or door misalignment resulting from an uneven floor is not covered under the 10-year structural warranty.

3. The 24-Hour Inspection Rule (Fragile Components)

• The 8mm Glass: The large tempered glass door is a high-value component. You must unbox and inspect it and report any transit damage, chips, or cracks within 24 hours of delivery.
• Post-Assembly: Once the sauna has been installed, the glass is no longer covered for breakage, as this is typically caused by accidental impact or frame stress from an unlevel base.

4. Natural Wood & Finish Maintenance

• Black Wood Finish: The exterior Hemlock features a premium black finish. Clean only with a soft, slightly damp microfiber cloth. The use of chemical solvents or abrasive cleaners will damage the finish and void the cosmetic warranty.
• Interior Hygiene: The Abachi wood interior is untreated for your safety. To prevent salt staining from perspiration, always use towels on the benches.
• Organic Nature: Minor variations in wood grain or fine surface lines (checking) are natural characteristics of timber and do not affect the 10-year structural integrity.

5. Claims Procedure

In the event of a technical issue:

1. Reference: Provide your original purchase record and the EAN (HL-MOON4-BLK).
2. Electrical Evidence: For electronic claims, you may be asked to provide proof of the professional 32A hardwired installation (e.g., an Electrical Installation Certificate or photo of the isolator switch).
3. Smart Diagnostics: Ensure the unit is connected to WiFi to allow for potential remote firmware updates.
