Installation and Maintenance Instructions.
THESE INSTRUCTIONS MUST BE READ FULLY BEFORE COMMENCING INSTALLATION.
Owner / installer: The life of this apparatus and its eciency will be increased if
its use and maintenance is carried out in accordance with these instructions and
current statutory requirements. The installation and initial adjustments should
be carried out by a qualied and competent technician. Hydor Limited should be
consulted before substituting or tting parts from another manufacturer. It is the
responsibility of the installer to verify that the installation is in accordance with all
current statutory requirements and the owner is given the current User’s Manual.
Any modications to the fan or its installation, even the smallest
modication, change or elimination of security components or pieces
that inuence the eciency or loss of ventilation, will result in the CE
Certication and Hydor’s warranty being cancelled.

1. General
1.1 It is important these Installation and Maintenance Instructions are fully
adhered to.
1.2 Full details of the unit supplied are shown on the product nameplate. If in
doubt about any detail contact Hydor or its agents for clarication.
1.3 All electrical installation must be carried out by suitably qualied and
competent personnel in accordance with all current statutory
requirements.
1.4 These instructions cover only the Hydor product and do not include
the supply or installation of any safety equipment that may be required
e.g. adequate guarding or protection from rotating parts and proper
electrical isolation.
1.5 Any declarations made by Hydor about product installation and safety,
are dependent on the fan equipment being used within installations which
themselves meet the requirements of the relevant Standards and
Directives of your region.
1.6 The fan is designed for use in an ambient temperature of -20°C up to a
maximum of +70°C, speed controlled operating
temperatures of -20°C and +50°C and up to 95% relative humidity. EC fans
are designed for ambient temperatures up to +60°C. The fan is not
suitable for corrosive or explosive atmospheres.
1.7 The installer should provide easy access to the fan to facilitate future
maintenance.
1.8 The installer should ensure the fan is adequately supported.
1.9 This product is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction
concerning use of the product by a person responsible for their safety.
Children should be supervised to ensure that they do not play with
the product.
1.10 At end-of-life, the unit must be disposed of in an environmentally friendly
manner by suitably qualied and competent personnel in accordance with
the requirements of applicable Standards and Directives.
2. 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, Hydor should be
contacted prior to the installation.
2.3 The fan must be securely mounted in the desired position to suit the

application. The fan can be mounted at any angle.
2.4 Check the details on the motor 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 fan 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 backow of gases into the room from the open ue of gas or
other fuel burning appliances.
3. Start Up
3.1 Before power is supplied to the unit, check that the wiring is correct as per
the fan connection diagram.
3.2 At initial start-up, check that impeller rotation and airow direction is
correct.
3.3 Check that the motor amperage drawn does not exceed the nameplate
rating.
3.4 Minimum interval between consecutive starts: 5 minutes.
3.5 Maximum 1 connection from power supply cycle per 5 minutes.
4. Fan Maintenance
4.1 Inspection of the fan at least once every 3 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.
4.2 All fastenings including electrical should be checked for tightness. In
addition, all rotating items should be checked.
4.3 Bearings are of the ‘sealed for life’ type and will not need a detailed
inspection.
WARNING: This fan is tted with an auto-reset thermal contact which
switches the fan o in the event of a fault condition. Once the motor
cools down the fan may start unexpectedly.
Only a suitably qualied and competent person may carry out
maintenance after the electrical supply has been isolated.
5. Guarantee
Hydor will, free of charge, within a period of 3 year from the date of
dIspatch from their works, repair or at its option replace any goods
which are proved to have defects as a result of defective materials or
workmanship. The goods MUST be returned to Hydor carriage paid
for examination.

149-CD-POT
149-CD-POT
The 149-CD-POT is a commissiong device designed to be used with our EC range of fans.
This device will be as standard with our box fan range from May 2018.
The device will allow the for the installer to set the maximum operating speed of the fan that it is
connected to.
The installer or commissioning engineer can adjust the fan speed using the potentiometer built onto the
149-CD-POT board. This potentionmeter can either be used for single speed adjustment or to set a
maximum speed for the fan to operate at when an external control source is used.
If external speed control is required, the jumper connection next to the potentionmeter on the board
would need to be removed, the installer can then connect to ST1 (using the diagram provided).
When an external speed control is tted, the maximum speed setting available to the external control is
limited by the potentiometer setting of the commissioning device.
