2.0 Installation
WARNING – The fan must be isolated from the power supply during installation and maintenance. The fan must be earthed in
accordance with the local regulations.
2.1 Upon receipt, the fan equipment should be visually inspected to check for any damage. Ensure that the impeller is free to rotate.
2.2 If there are any queries concerning the fan equipment, Elta Fans Ltd should be contacted prior to the installation.
2.3 The fan must be securely mounted and the panels adjusted to suit the desired position to suit the application, straight through or 90°
airflow. The fan can be mounted at any angle.
2.4 Check the details on the motor/fan rating plate to ensure that the correct power supply (voltage, frequency and phase) is available.
An incorrect power supply will lead to permanent damage to the motor.
2.5 Refer to the appropriate wiring diagram. Ensure that all earth connections are made.
2.6 Means for electrical disconnection must be incorporated in the wiring installation in accordance with the relevant wiring and electrical
regulations.
2.7 Precaution must be taken to locate the exhaust discharge terminal so as to avoid the backflow of gases into the room from the open flue
of gas or other fuel burning appliances.
3.0 Storage
3.1 The storage place must be vibration free, clean, dry and not subject to extreme temperature variations.
3.2 When storing for prolonged periods, whereby non rotation of motor occurs, we recommend electrical and bearing inspection, as they
may have incurred damage or require possible re-lubrication.
4.0 Start Up
4.1 Before power is supplied to the unit, check that the wiring is correct as per the fan connection diagram.
4.2 At initial start-up, check that impeller rotation and airflow direction is correct.
4.3 Check that the motor amperage draw does not exceed the nameplate rating.
5.0 Fan Maintenance
5.1 Inspection of the fan at least once every 12 months is recommended to ensure that the motor, fan blades, and supporting guards, are
clean. Any build up of dust and deposits on the blades or guards should be removed using a non-abrasive cleaner.
5.2 ll fastenings should be checked for tightness. In addition, all rotating items should be checked.
5.3 Bearings are of the ‘sealed for life’ type and will not need a detailed inspection.
5.4 The Qube-HT range has an easily removable motor/impeller assembly, and panel arrangement fixed to Multi-thread “U” nuts, ideal
for frequent cleaning.

Elta Fans Ltd will, free of charge, within a period of 1 year from the date of dispatch from their works, repair or at its option replace any
goods which are provided to have defects as a result of defective materials or workmanship. The goods MUST be returned to Elta Fans
Ltd carriage paid for examination.
7.0 Wiring
IMPORTANT - Correct rotation must be ensured as Air flow direction will be correct even if the impeller is rotating in the wrong
direction. Incorrect direction of rotation will result in lower air volumes, increased noise and higher electrical current, which will harm
the motor.
