Application
Thermowarm TWT is a series of easily installed
convectors designed for heating installations
of a more technical nature such as offshore,
service areas, utility rooms and vehicles. TWTC
can also be used in corrosive and aggressive
environments.
Enclosure class TWT: IP44, TWTC: IP54.
Mounting
The appliance is supplied with a pre-installed
wall bracket for attaching horizontally to the
wall using four screws. There is a template
for placing the screws on the bottom of the
carton. Stick a sharp instrument through the
marks on the carton to mark where to place
the screws. The top two holes are “keyholes”.
See the dimensions on the introductory pages.
For minimum distance, see diagrams on
introductory pages.
Connection
TWT100 is designed for permanent installation.
The installation, which should be preceded by
an isolator switch with a contact separation
of at least 3 mm, should only be wired by a
competent electrician and in accordance with
the latest edition of IEE wiring regulations.
TWTC is equipped with a cord and plug for
connection to earthed outlet sockets.
Replacement of cable
If the cable is damaged the unit must be sent to
Frico for replacement. Contact Frico Technical
Support.
Start-up
When the unit is used for the rst time or after
a long period of non-use, smoke or an odour
may result from dust or dirt which has collected
on the element. This is completely normal and
disappears after a short time.
Maintenance
In all electrical heating appliances, small
clicks can occur due to movement when the
material expands and contracts with changes in
temperature.
As the components are maintenance-free, no
maintenance other than cleaning is necessary.
The frequency of cleaning can vary depending
on local conditions, although it should be at
least twice a year. Grilles and elements can
be vacuum cleaned or wiped using a damp
cloth. Use a brush when vacuuming to prevent
damaging sensitive parts.
Avoid strong solvents such as acetone or
similar, as well as alkaline or acidic detergents.
The plastic end covers must not be exposed to
oily substances.
Overheat protection
The convector is tted with overheat protection.
TWT100: The overheat protection can be reset
by pushing the button on the end plate of the
heater.
TWTC: The overheat protection is reset by
pressing the button located under a threaded
cover at the side of the heater. The cover can
be removed by a screwdriver.
Control
Thermowarm features an integrated
thermostat with setting range 0 – +35 °C. On
TWTC the thermostat is concealed to make it
dicult for unauthorised persons to change
the temperature setting. TWT100 has a circuit
breaker.
Packaging
Packaging materials are chosen with
consideration to the environment and are
therefore recyclable.
TWT100: A Celsius scale is marked on the side
of the thermostat dial. The dial is on the right
side of the heater. The scale of the thermostat
dial can be turned to calibrate the thermostat
to the actual room temperature.
TWTC: The thermostat is protected under a
threaded cover on the right side of the heater.
The cover can be removed by a screwdriver.
The thermostat is set by turning the notch to
the desired temperature. See the introduction
pages.
