SERVICE & MAINTENANCE
Failure to adequately maintain the unit and provide a suitable cleaning schedule will
WARNING:
result in a loss of performance and reduced life expectancy of the air-curtain and
possible overheating and fire risk with electric heated units.

Every 3 months

Before servicing, isolate and disconnect the air curtain from the electrical power.
WARNING:
The following servicing and maintenance must be carried out by a competent electrician
WARNING:
or a Biddle appointed technician.
Always disconnect and isolate the mains electrical supply before installing, maintaining or repairing this
equipment. With 2.5m vertical air curtains there are two air curtains, one stacked on top of the other.
Isolate the mains supply to both top and bottom air curtains.
To ensure the air curtain operates at full efficiency the back casing and inlet casing panel, fan impellers,
housings and motors must be kept free of dust and debris. Build up of dust on the fan impellers can
cause vibration, noise and excessive wear on the motor bearings.
Frequency of cleaning will depend on the environment, but we would recommend that the unit be
cleaned a minimum of every 3 months (failure to adequately maintain the unit and provide a suitable
cleaning schedule will result in performance degradation and reduce the life expectancy of the air-
curtain).
Remove the back and inlet panels from the air curtain. Vacuum and clean the build-up of dirt and debris
within the air-curtain (please note that the motor(s) are permanently lubricated and require no additional
lubrication).
Once the air curtain has been cleaned check all electrical connections within the unit ensuring terminals
are tight and that crimped connections have not become loose.
Re-install the back and inlet panels. Reconnect the electrical supply and fully function test the air-curtain
to ensure correct operation (See Commissioning).
