Operation, Maintenance and Installation Manual

Section A – Unit Operation NOTE The Blanket Warming Cabinet is factory set to 60°C

Before starting the Unit The unit 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 unit can then be connected to an earth leakage circuit breaker protected circuit if required. Plug into standard 240V outlet.

Starting the Unit Power ON, the preset temperature of the cabinet appears for approximately five seconds. After five seconds the unit switches to display the actual cabinet temperature.

Changing the set temperature (lock out feature) AUTHORISED PERSONNEL ONLY Authorised operators can change the temperature by holding the up and down temperature buttons at the same time for a total of 5 seconds. The temperature can then be adjusted. The setting will revert back to tamper proof 5 seconds after the temperature is adjusted or if the up and down temperature buttons are not pressed within 5 seconds. The unit has a built in electronic over temperature cut out which will switch off the elements if the selected temperature is exceeded by 5°C, and ‘Ot’ will flash on the display panel. (See Fig 1) If the electronic cut out fails, a secondary safety bi-metallic cut out temperature switch will switch off the power to the elements and the controller.
