Make sure that after end of installation and when using the fan the impeller would rotate in correct direction. After mounting
fan to the proper construction turn on fan for 1 sec. and check the impeller rotation direction and generates air flow in correct
drection. The checking motor direction should be made in accordance with chapter 1 and 4 and with caution.
The work with impeller rotating in the wrong direction reduces fan parameters and may damage it. In case of improper impeller
rotation turn off the power supply, wait until impeller stops to move, and change proper wires in the terminal box (three phase
power supply), contact with manufacturer (single phase power supply fan).
4. USE
During fan use follow the guidelines contained in 1 section of this instruction and
use guidelines
.
Before first start of the fan follow guidelines from chapter 5.
4.1 use guidelines
•
Make sure that turning on of the fan does not make any risk for personnel and property.
•
Fan cannot work with voltage, frequency, current higher than shown on the fan nameplate.
•
The fan is designed for continuous operations (S1) – too high frequency of turning may lead to the motor regulator overheat and damage
(see also chapter 4.2 Guidelines for regulation).
•
The fan is not adapted to rotation speed regulation.
Power supply parameters (voltage, frequency) have to be equal with those indicated on
the nameplate.
•
In case of activation of any electrical protection, detection of damage, working with current greater than specified on the fan nameplate –
unit must by immediately turn out off use.
•
The device is adapted to work in certain range of characteristic. Too high volume flow rate of medium, start/work of device with completely
closed inlet and/or outlet may lead to motor overheat caused by current consumption exceeding value on the rating plate (current consumed
by fan grows as resistance of installation grows)
5. MAINTENANCE, REVIEW
During maintenance and review follow the guidelines contained in 1 chapter of this instruction and maintenance guidelines.
5.1 maintenance guidelines
•
Fan must be subject of regular review and maintenance (point 5.2). The set between routine checks and maintenance should be determined
by user, based on the observation of unit and specific conditions and actions. If irregularities are found, the device must be taken out of
service and repaired.
•
To clean fan use slightly damp delicate material. It is prohibited to use detergents, liquids under pressure and tools that may scratch the unit
surface. After fan cleaning (after end of maintenance) turn on the fan for 30 minutes (with full speed).
•
In case of long fan downtimes it should be run at least once per month for 2 hours (with full speed).
•
Prevent the accumulation of dust/dirt on and inside the fan. Dirt accumulated on: grids – may reduce the fan parameters; impeller – may
lose it balance; housing and motor – can reduce the cooling; hot surfaces – in extreme situations may ignite. If the device is secured by filter
- filter should by regularly inspected and replaced if it pollution is too high. The dirt accumulated on the filter reduces the fan parameters.
•
Ensure that there are no foreign bodies near and inside the fan, the impeller is not blocked, the unit is clean, dry and secured after
maintenance and review.
•
Fan motor is equipped with bearing with life expectancy 40 000 hours (ambient temperature 40˚C). Bearings do not need refill lubricate.
5.2 Unit maintenance and review
During review and before first use of the unit or after long time period of storage attention to the following should be paid:
•
accumulation of the dirt on the unit and filter (if used), state of grid / covers,
•
is the device stable, not damaged, the structure is complete, moving elements can move freely,
•
if there are any foreign bodies or loose elements inside the fan,
•
if there is loose bearing and rotating the shaft cause in its heavy/noisy work,
•
are connecting elements tightened, is fan surface without corrosion, are electrical wires not damaged,
•
is the safety equipment working and property set, is shock protection effective,
•
if there are leaks from the motor, overheating and vibrations.
During operations, especially after first start pay attention to:
•
correct operation,
•
there are no unusual noises and vibrations, leaks from the motor, overheating or vibrations,
•
the grids are in proper condition,
•
the fan current is not higher than show on nameplate. Exceed of current placed on the name plate could by a sign of unit damage.
6. REPAIR, WARRANTY
Use only original spare parts and original accessories. Fan repairs need to be made by manufacturer or after manufacturer permission.
Warranty conditions are placed in the fan warranty card.
7. DISMANTLING AND RECYCLING
Disconnect unit from its power supply, and dismount according to the guidelines from section 1 of this instruction. Therefore, please deposit
all left-over material and packaging in their corresponding recycling containers and hand in the replaced machines to the nearest handler of
this type of waste product.
