Safety Information
This machinery must not be put into operation until prior
to reading mounting instructions and safety information.
All units are intended for transportation of air in air
handling systems. They are meant to be used after
building them into machines or duct systems or after
contact protection grid have been installed. (EN ISO
13857). The unit must be connected to ducts on both
sides (inlet/outlet). When there is a risk of water
entering the motor, via the ducts, external protection is
required. No moving parts shall be accessible after
installation. The units are not to be used in hazardous
environments or connected to flues. The TLP units must
not be installed outdoors. Safety accessories (i.e. motor
protection, safety grille) may not be dismounted, short
cut or disconnected. CAUTION Before servicing or
maintenance, switch off power, (all-pole circuit breaker),
and make sure the impeller has come to a standstill.
CAUTION The equipment can have sharp edges and
corners which may cause injuries.CAUTION, be careful
when opening the units service-hatches in case the unit
is mounted with the inspection hatch downward.
Transportation and Storage
The TLP units are packaged at the factory to withstand
normal transport handling. When handling the goods use
suitable lifting equipment in order to avoid damage to
equipment and personnel. Do not lift the unit by the
connecting cable, connection box, impeller or inlet cone.
Avoid blows and shock loads. Store the unit in a dry
place protected from weather and dirt until final
installation
.
Installation
Refer to Safety information above. Installation, electrical
connection and commissioning are only to be carried out
by authorised personnel and in accordance with
requirements and demands. Electrical connections are
made according to the wiring diagram, markings on
terminal blocks or on cable. All 3 phase units are
delivered from factory in 400V 3~ connection. CAUTION
do not use metal compression gland fittings with plastic
terminal boxes. Use a dummy plug seal for the
compression gland fitting as well. If the wiring to the K
fan in the unit is carried out using cables with diameter
12-14 mm, the entrance bushing must be replaced
(applies to type K). Assemble the TLP unit in the
direction of the airflow (see arrow on unit). The unit must
be installed so that vibrations are not transmitted to duct
systems or the frame of the building. (Suitable
accessories like fast clamps and diffusers are available).
Make sure the assembly of the fan is firmly fixed and
stable. The smaller sized of TLP 125 to 200, can be
mounted upside down in false ceilings. In this case the
heater must be rotated so that the connection box with
the overheating protection switches face upward or to
the side. NB TLP 315 cannot be placed upside down.
The TLP units must be mounted so that service and
maintenance can be performed easily and safely.
Disturbing noise can be avoided by installing silencer
(available accessory).
For frequency regulation an all pole sinus filter must be
mounted between motor and frequency controller
(version all poles: phase to phase, phase to earth). The
TLP unit is meant for continuous use within the
temperature range stated.
The fans inside the TLP unit are equipped with manual
thermal contacts (reset by cutting the current, motor
protection SP1), must be taken into consideration when
connecting surrounding equipment with automatic on/off
function.
Operation
Before initial operation, check the following:
- Electrical connection has been properly completed.
- Protective conductor has been connected.
- Safety devices in place (protection grid)
- Leftover installation materials and foreign materials
have been removed from the casing.
When putting into operation, check thefollowing:
- Connection data corresponds to the specifications on
the nameplate: Maximum v6%, -10%, according
to IEC 38. Rated current must not be exceeded with
more than 5% at rated voltage. CAUTION when speed
regulating by reducing the voltage the motor current may
exceed the rated current at a lower voltage. In this case
the motor windings are protected by the thermal contact.
- Smoothness of motor operation, (no abnormal noises).
-Fans must only be operated by a person that has
sustainable knowledge or education within this field or
handling must be carried out with the supervision of such
person.
Maintenance, Service and Repair
Before maintenance, service or repair, make sure that:
- Power supply is interrupted (all-pole circuit breaker).
- Fan impeller has come to a complete standstill
- Observe personnel safety regulations!
The fan in the unit should be cleaned when necessary,
at least 1/year to avoid imbalance and unnecessary
damage to the bearings. Periodical changing of the filter
inside the unit will prolong the time interval between
each cleaning of the fan. The fan bearings are
maintenance free and should only be replaced if
damaged. Do not use a high-pressure cleaner (steam
jet) when cleaning the unit. Listen for abnormal operating
noise.
Resetting of the thermal trips
Manual thermal trips (SP1) are reset by disconnecting
the mains for approx. 10-20min.
Make sure the unit has not been blocked or that the
motor protection has tripped. Contact the supplier if the
motor does not start after controlling and/or resetting the
motor protection.
