Application area
The heater fans type CAT are intended
for heating buildings. The compact and
robust design makes the fans ideal for use
in different areas, e.g. warehouses, garages,
workshops, shops, etc. The heater fans are
approved according to SEMKO, NEMKO,
DEMKO and FIMKO. Enclosure class: Splash-
proof design.
Electrical connection
The heater fans are fitted with a terminal
block for connection to the mains supply
and terminal blocks for connections to an
external isolator, thermostat and timer.
There are two knockouts at the rear for the
external connections that should be fitted
with appropriate grommets to ensure the
enclosure's classification.
The heaters can be connected for either
230V3~ and 400V3N~. The 3 kW model can
be connected for single phase. Note! Other
models cannot be connected for single phase.
Installation
The installation should be permanent
and carried out by a qualified technician
according to applicable directives. The
installation should be preceded by a fully
isolating switch with at least a 3 mm gap and
preferably fitted with a status lamp. Ensure
that the mains voltage and the information on
the type plate correspond. The wiring diagram
can be found in the inside of the cover.
NOTE! The heater must be dead when
carrying out all work on it.
