## Long description

Master TS3A 2400 W (Model 4012.354) is a compact infrared radiant heater designed to deliver direct, focused heat for indoor and sheltered outdoor environments. The unit produces 2400 W of nominal power and uses infrared radiation to warm people and objects quickly rather than heating the surrounding air. Its compact footprint and targeted heat output make it suitable for spot heating in workshops, terraces, temporary work sites and other areas where rapid, localized warmth is required.
Advantages
The heater provides instantaneous radiant heat with minimal warm-up time, enabling prompt comfort for occupants. Its infrared operation concentrates energy on surfaces and people, offering efficient spot heating and reducing energy lost to ventilation. The compact design allows flexible mounting and installation in constrained spaces, while the robust construction supports reliable use in commercial and light industrial environments. The device operates quietly and requires little maintenance.
Suitable for
Workshops and garages requiring localized heating
Terraces and covered outdoor seating areas
Temporary job sites and construction shelters
Retail or service counters needing spot warmth for staff or customers
Key specifications
Heating principle: infrared (radiant) heating
Nominal power output: 2400 W
Installation: wall or ceiling mounting compatible with compact footprint
Intended environments: indoor and sheltered outdoor areas
Operation: silent running with low maintenance requirements
How to use
Install the heater according to the mounting instructions, ensuring secure attachment to a wall or ceiling and adequate clearance from combustible materials. Aim the radiant panel toward the zone or seating area to be warmed; infrared heat is most effective when directed at people or objects rather than into open air. Connect the unit to a properly rated electrical supply and use any integrated controls or switches to select the required heat output. Regularly check mounting fixtures and the unit exterior for damage or dust buildup and clean the exterior surface when cold.
Usage recommendations
Position the heater to avoid direct exposure to rain or heavy moisture and maintain recommended clearances from combustible surfaces. For best efficiency, use the heater for targeted spot heating rather than attempting to heat large open volumes. Combine with appropriate safety devices and follow local electrical installation regulations.
