The MACO MULTI hardware system is designed for turn-only and turn&tilt windows, offering a comprehensive solution for window operation and security. This system is intended for use by certified specialists only, not end-users, ensuring proper installation and maintenance.

Function Description:

The MACO MULTI system provides various functionalities for windows, including turn-only, turn&tilt, and tilt-first operations. It incorporates components such as scissor stays, hinges, pivot posts, and closing elements to facilitate smooth and secure window movement. The hardware allows for sash adjustment in multiple directions (lift/lower, side adjustment) and gasket compression, ensuring optimal sealing and operation. Specific variants like MULTI-MATIC, MULTI-TREND, MULTI POWER, and MULTI MAMMUT cater to different window types and requirements. The system also includes safety features like mishandling devices on turn&tilt windows and secure hinging/unhinging mechanisms.

Important Technical Specifications:

While specific technical specifications like material composition or load capacities are not explicitly detailed, the manual highlights adjustment ranges for various components. For instance, lift/lower adjustments for MULTI-MATIC/MULTI-TREND corner hinges are +2.85/-1.8 mm, and for MULTI-MATIC/MULTI-TREND stay and hinge, they are -3/+5 mm. Gasket compression for MULTI-MATIC scissor stays is -1/+1 mm, and for MULTI-MATIC turn-only hinge sash parts, it's -1.5/+1.5 mm. Pivot post adjustments vary by type: PVC/DT/TO/AS pivot post has -2.3/+2.3 mm for side adjustment and -2/+3 mm for lift/lower. Drill-in pivot posts have -2/+2 mm for side adjustment and -2/+2 mm for lift/lower. MULTI MAMMUT pivot posts allow -3/+3 mm for side adjustment and -2/+3 mm for lift/lower. Tilt-only sash settings include side adjustment of -2.5/+2.5 mm and lift/lower of -2/+2 mm. Gasket compression on cams ranges from -0.55/+0.55 to -0.75/+0.75. These precise adjustment values underscore the system's engineering for fine-tuning window performance.

Usage Features:

The MACO MULTI system offers versatile usage through its various components. The turn-only function allows the window to open inwards like a door, while the turn&tilt function provides both inward opening and a tilted position for ventilation. The tilt-first option prioritizes the tilt function before allowing full opening. The hardware is designed for ease of adjustment, with clear instructions for setting scissor stays, hinges, and pivot posts. The manual emphasizes the importance of using intact tools and trained personnel for any adjustments or maintenance, particularly for critical components like pivot posts and scissor stays, and for hinging/unhinging sashes. The system also incorporates security features like the i.S. Security roller cam and locking cam for enhanced window security.

Maintenance Features:

Maintenance is crucial for preserving the surface finish and functionality of the MACO MULTI hardware. The manual provides detailed guidelines for protection against soiling, corrosion, and corrosive/acidiferous cleaning agents.

Protection against soiling: Hardware should be kept free of debris, plaster, mortar, and other contaminants during the building stage. Components should be protected from dust, dirt, and paint.
Protection against corrosion: Adequate ventilation of hardware and rebate areas is essential to prevent direct moisture or condensation. Aggressive vapors combined with condensation can lead to corrosion. Timber frames and sashes with high tannic acid content must be treated with suitable surface coatings to prevent evaporation. Acetic acid or cross-linked acidic sealing compounds should not be used. The hardware must not be damaged by sharp tools, and fittings should be cleaned with a moist cloth, avoiding permanent wetness.
Protection against corrosive, acidiferous cleaning agents: Fittings should be cleaned with a soft, lint-free cloth and a mild, pH-neutral cleaning agent in diluted form only. Aggressive, acidic, solvent-based, or abrasive cleaners (scouring pads, steel wool) are strictly prohibited as they can damage the hardware. Damaged hardware can impair function and safety, requiring immediate repair or restoration. Re-treating cropped edges of TRICOAT-PLUS fittings with TRICOAT-PLUS touch-up paint is recommended.
Warranty claims: Warranty claims are only accepted if all maintenance operations have been carried out according to the specified intervals in the end-user operating instructions and if the unit was installed correctly by a certified specialist.
Hinging and Unhinging: The manual provides step-by-step instructions for hinging and unhinging the sash for different hardware types (MULTI-MATIC/MULTI-TREND scissor stay hinge – PVC/DT/AS, MULTI-MATIC/MULTI-TREND scissor stay hinge – stay and hinge, MULTI MAMMUT scissor stay hinge, and MULTI POWER). These procedures often involve removing covers, pulling hinge pins, opening the sash to a specific angle, and carefully lifting the sash. For MULTI POWER, a mishandling device needs to be triggered, and the handle turned to the tilt position before lifting the scissor stay arm. The manual stresses that for MULTI MAMMUT, the scissor stay hinge pin must always be installed.

The MACO MULTI system is designed for longevity and reliable performance, provided that the specified maintenance and adjustment procedures are followed diligently by certified professionals.
