Operation, Maintenance and Installation Manual 1.1 Device Operation NOTE The Drying Cabinet is factory set to 70°C

Before starting the Drying Cabinet The Drying Cabinet should be run initially on a power supply not protected by an earth leakage circuit breaker for approximately three hours. This will allow any moisture in the heaters to dry out. The Drying Cabinet can then be connected to an earth leakage circuit breaker protected circuit if required. Plug into standard 15A 240V outlet.

Note: The Drying Cabinet is recommended for use in a controlled temperature environment. Starting the Drying Cabinet Press the Power ON button on the display, the pre-set temperature of the cabinet appears for approximately five seconds. After five seconds the unit switches to display the actual cabinet temperature and will heat to the set target temperature

2.3 Wall Recessed Devices Plug into standard 240 Volt outlet (plug shall be accessible after installation). Outside dimensions pass through – 1850H x 755W x 690D. Clearance space dimensions are required; at least 150mm per side and 500 mm on top. Drying cabinet sides are to fit through the wall cavity, ensuring that the power cord and filter are not obstructed. Placement should be typically 150mm from the operating panel side doors. A 5-10mm gap between the side panel and the timber is required. Clearance on the top of the Drying Cabinet needs to be typically 500mm. This allows access to replace the electric motor, heating elements etc. Allowing for this 500mm may require the facility to install a false panel in the dividing wall. All electrical service work must be accessible through the top of the Drying Cabinet. Position the Drying Cabinet in the cavity, ensuring that the doors can open and close with clearance for the doors at hinge point. Issue 23
