DESIGN AND OPERATING PRINCIPLE

Depending on the model the fan casing is made of polymer coated steel, aluminium or galvanized steel. The units feature electronically commutated (EC) direct current motors with an external rotor and centrifugal impellers with backward curved blades. EC motor is free of friction and wear parts such as a commutator and brushes. These components are replaced by a maintenance- free electronic circuit board. In conditions of low temperatures and high humidity, in order to avoid freezing or water ingress into the duct, the unit must be operated continuously.

MOUNTING AND SET-UP

BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER). WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.

• Fans are designed for horizontal mounting on a flat roof directly above an air duct or a ventilation shaft.
• In order to avoid ingress of water and snow into the ventilation duct, it is possible to install a fan on the mounting frame.
• The fan is connected to the ventilation duct by means of a counter flange, which is attached directly to the fan base.
• The fan base has holes for fixing bolts that attach the fan to a stationary even surface or to a mounting frame.
• In the TOWER-V 225 ЕС, TOWER-V/H 500 ЕС, TOWER-V/H 630 ЕС models the counter flange is attached together with the fan inlet ring.
• A mounting frame, a counter flange and mounting bolts are not included in the delivery set and must be purchased separately.

INSTALLATION EXAMPLES

CONNECTION TO POWER MAINS

DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

• The unit is rated for connection to power mains with the parameters specified in the «Technical specifications» section, according to the wiring diagram.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of the unit. The trip current of the automatic circuit breaker QF must exceed the maximum current consumption of the unit (refer to the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.

Electrical connection is made on the terminal block located in the remote or integrated terminal box of the electric motor. The terminal designations are shown on the label inside the fan casing.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION

• The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
• When carrying out fan maintenance, it is necessary to partially disassemble it in order to access contaminated parts of the fan.
• The impeller blades require thorough cleaning once in 6 months.
• Use a soft dry cloth, brush or compressed air to remove dust.
• Carry out wet cleaning using warm water and a mild household detergent.
• Protect the electric motor against liquid ingress.
• Do not immerse the unit in water!
• Do not use aggressive solvents, or sharp objects as they may damage the impeller.
