Prima Klima PK125EC-2 Instructions

Instructions for PK125EC-2

Safety instructions

Please read the assembly and operating instructions before commissioning Prima Klima duct fans. Our fans are designed to promote indoor air
in ventilation systems. To avoid the creation of condensation, fans should be isolated in unheated rooms. Fans can be commissioned only
following successful installation in the ventilation system, or following the installation of protection against contact (EN ISO 13857). Suitable
protection systems must be installed to protect the fan against the ingress of water from the sewage system. No moving parts may be present
in the vicinity of the motor following installation. Fans are not suitable for operation in hazardous areas. Fans are allowed for indoor use only
and must not come into contact with liquids. Outdoor operation is not possible. The power supply must be interrupted at all poles in the event
of necessary maintenance. The motor impeller must be stationary before opening or maintenance. All Prima Klima fans have a temperature
safety shut-off function that switches the engine off in case of overheating. The engine will restart automatically once it has cooled.

Transport and storage

Prima Klima fans are securely factory packed solid so as to be protected against normal transport conditions. At temperature below 5° C,
special transport conditions are required in order to avoid breakage of plastic, i.e. the box must be handled carefully. The fan may not be
transported on a connection cable. Avoid exposure to shock and vibration. Fans must be stored in a dry place that is protected against the
weather and dust and in temperatures between -10 and 45°C.

Assembly

The safety instructions detailed above must be observed. Assembly and electrical connection may only be performed by trained personnel.
The relevant VDE and other applicable regulations must be observed. The electrical connection must be installed in accordance with the circuit
described in the terminal box. The fan must be mounted in the correct flow direction (arrow on the sticker). The fan must be mounted that no
vibrations are transmitted to the duct system. Fan noise can be avoided through the use of a suitable silencer.
The fan mounting bracket can used to anchor the fan.
Turn the fan to achieve the optimum assembly position.
Ideally, the power supply should be at the bottom.
Caution !!!!
The metal mounting bracket
is not burred - there is
a risk of injury.

Switch

The switch can be used to manually set the fan power level at 1 or 2. The relevant performance data and characteristics are presented in Table
1.1.

Commissioning

Before turning on the fan on, check if the electricity has been connected correctly. Has the protective conductor been connected? Has any
leftover connection material been removed from the fan? Commissioning must be checked by trained personnel in accordance with
regulations.
CAUTION !! The fan is not speed-controlled and may not be connected to a phase angle control or a regulating
transformer.

Maintenance and repair

The fan must be disconnected from the power supply before maintenance or repair. The motor impeller must be stopped. Safety regulations
must be complied with. To ensure a long lifecycle, the inside of the fan should be cleaned once per year. If the fan isn't running, interrupt the
power supply for a few minutes and try again. The motor requires approximately 20 seconds to go through its self-checking process before the
motor restarts. If the fan still does not work, please contact your dealer.
