Timer kit, complete LF PRG30001

A mechanical timer controls cooking duration in convection steam ovens, where precise heat and humidity cycles transform raw ingredients into finished dishes. The timer winds to the set interval, then counts down while a spring-driven mechanism advances the dial. When the pointer reaches zero, a bell rings to alert the operator, ensuring the oven switches from active cooking to holding or cooling without over-processing. This method removes guesswork from multi-stage programmes, allowing chefs to organise other tasks while the oven completes its cycle.

To use the timer, the operator turns the dial clockwise to the desired cooking time, up to 120 minutes. The oven's control panel recognises the timer as the master clock for the selected programme, so once the dial is set, the operator starts the oven and leaves the timer to run. When the bell sounds, the oven either stops heating or moves to a holding phase, depending on the programmed sequence. The operator then opens the door, removes the food, and resets the timer for the next batch.

The timer is housed in a compact metal casing designed to fit the control panel cut-out of PIRON G5, G7, G12, P 4 64U, and P 4 64 UI convection steam ovens. It replaces the original timer without modification to the oven's wiring or mounting points, so installation requires only basic tools and no additional parts.

This timer kit is specified for PIRON convection steam ovens only, ensuring compatibility with the oven's voltage, control logic, and mounting dimensions. The 120-minute range covers the full spectrum of professional cooking programmes, from rapid baking to slow steam-roasting, while the mechanical design requires no power supply of its own, drawing current only through the oven's existing circuit.

Cleaning is limited to wiping the dial and casing with a damp cloth to remove dust or grease. The timer should not be immersed in water or exposed to high-pressure steam, as moisture can enter the mechanism and cause corrosion or misalignment of the internal spring and gears.

The kit is supplied as a single unit, with no variants or additional components. It is listed in the LF catalogue under oven spares and accessories for PIRON models.
