tubing, face masks, anaesthetic bags and other ancillary equipment.
A total of six (6) stainless steel shelves is provided. The shelves are removable, with 6 positions
including the base.
The cabinet is insulated with 25mm approved type insulation.
Magnetic door latches are fitted with toughened bi-parting glass doors and gasket to ensure
effective seal when the doors are closed.
All external panels are fabricated from satin finish stainless steel 0.9mm thick, 304/4 type.
A centrifugal fan is provided to circulate air throughout the chamber.
A solenoid operated damper is provided to allow air to be exhausted from the chamber. An inlet
for make up air is provided.
The heating bank (located in the air duct leading to the chamber) is controlled by a micro-
processor, which can be incremental set to 70°C.

Section A – Unit Operation
NOTE
The Drying Cabinet is factory set to 70°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.
NOTE: The unit is recommended for use in a controlled temperature environment.
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)
Note: This safety cut out is an automatic reset device.

Place instruments and utensils upside down where applicable.

Section C – Unit Installation
The cabinet must be installed level on adjustable legs.
Service Connections
Provide 98mm OD duct to atmosphere.
Electrical Connection – 240 Volt 15 Amp cycle.
Plug into 15 Amp G.P.O.
Wall Recessed Units
Plug into standard 240 Volt outlet. - Plug shall be accessible after installation.
Outside dimensions pass through – 1850h x 755w x 690d.
Cabinet clearance space dimension (eg at least 150mm per side and 500 mm on top) are to be
provided for the appliance.
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. There is
