Installation
General
The cabinet is supplied fully assembled and ready for use.
The following guidelines should be observed when installing the cabinet:
Site the cabinet in a draught free position with a minimum of 200mm from the top
of the cabinet to the ceiling to prevent obstructing the air inlet and to provide
access to change the pre-filter. Installation within a clean area is preferred as this
will maximise and prolong filter life.
Connect the cabinet to a 13A electrical socket.
Optional VFC relay.
A Volt-free contact is available as a factory-fit option. If fitted, it is located to the
rear of the cabinet next to the power inlet. This allows for connection to external
monitoring systems/BMS etc.
When the cabinet is powered on, after approx. 30 secs, the relay will be
energized, when the cabinet airflow alarm is triggered or the unit is powered off,
the relay is de-energized.
Relay is rated at 0.5A@125Vac / 1.0A@30Vdc/ 0.3A@60Vdc, normally open
contacts
An unterminated plug is provided for user connection and should be wired as
below.
