Hydor HEB Technical specifications

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 qualified and competent technician. Hydor Limited should be
consulted before substituting or fitting 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 modifications to the fan or its installation, even the smallest
modification, change or elimination of security components or pieces that
influence the eciency or loss of ventilation, will result in the CE Certification
and Hydor’s warranty being cancelled.

qualified and competent personnel in accordance with local regulations.

3. Delivery
3.1 All HEB units are tested and inspected prior to despatch and leave the
factory in good condition. Upon receipt, it should be examined for visible
damage, ensure that the impeller is free to rotate and that all parts listed
on the delivery note are present.
3.2 Any damage or shortages should be notified to the carrier immediately.
3.3 Hydor cannot accept any responsibility for damage sustained whilst
unloading from the carrier, or subsequent damage on site.
3.4 If there are any queries concerning the fan unit, Hydor should be
contacted prior to installation.
4. Installation
WARNING: All electrical installations must be carried out by suitably
qualified and competent personnel in accordance with local regulations.
4.1 The HEB range of fans is normally supplied assembled. The single phase
units are supplied with the Capacitor loose.
4.2 The fan must be securely mounted in the desired position to suit the
application. The fan can be mounted at any angle.
4.3 Precaution must be taken to locate any exhaust discharge terminals so as
to avoid the backflow of gases into the room from an open flue of gas or
other fuel burning appliances.
5. Existing aperture installation
5.1 If the HE fan is mounted using the 4x fixing holes in the mounting plate,
then the HEB will directly replace it as follows for the 630mm and 710mm
models. When replacing the 760mm HE with a 710mm HEB, the mounting
will need to be adjusted.

Old HE Fan Unit
New HEB Fan Unit

5.2 Isolate supply to HE fan.
5.3 Disconnect the wiring from the motor terminals. Make sure the wiring
is adequately marked for reconnection.
5.4 Withdraw all cables from the motor and detach from motor arms to clear
HE fan assembly.
5.5 Ensure the HE fan assembly is adequately supported to avoid injury or
damage.
5.6 Unbolt the HE fan assembly from its mounting (4x fixings in the mounting
plate).
5.7 Lift the HE fan assembly away from its mounting location and place out of
the way for disposal or recycling at a local facility.
5.8 The new fan can now be fitted as follows:
5.9 Lift the new HEB fan into the original mounting place.
6.0 The fixing holes will line up exactly to the HE fan fixing points for 630mm
and 710mm models. When replacing the 760mm HE with a 710mm HEB,
the mounting holes will move slightly.
6.1 Ensure the HEB fan assembly is adequately supported.
6.2 Fix the HEB fan assembly into the aperture in the same manner as the HE
fan was.
6.3 Re-run power supply cables to the new motor.
6.4 Connect wiring to new fan, see section 9. Please note
that if the fan is single phase, the capacitor value will have changed.
6.5 Secure all loose cable as required to make safe.
6.7 The fan is now ready to switch on and test.

Optional flanges attached to edges
Optional flanges ready to be
marked and drilled with fixing
locations
7. Additional steps when your existing HE fan is part of another Hydor
product installation (such as a HE sidewall unit):
In some instances, the fixing may not be by the 4 plate mounting holes,
but by fixings through the return flange around the outside of the HE fan
plate. If this is the case, there are 2 options for fan replacement.
Option 1
Return flanges are available as an optional extra and can be purchased
at the time of order. These will be fitted to the plate ready for you to install.
There will not be any fixing holes in the return flange supplied and these
will have to be drilled on site by the customer when fitting.

arms and prop removed

through the existing
mounting holes on the
HE unit 630mm and

Option 2
The existing HE fan plate can be left in-situ. The motor, arms and propeller
can be removed. The plate could then be cut down in-situ so that the new
HEB plate fan will use the existing plate 4 point fixings to locate it.
All other parts of the replacement instructions are still valid.
IMPORTANT: The unit is heavy. Use correct fixing hardware to secure the
unit. Observe recommended lifting practices to guard against injury.

8. Electrical Connection
Electrical wiring should only be undertaken by technically trained competent
personnel in accordance with good industry practice and should conform to all
local governing and statutory bodies.
8.1 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.
8.2 Refer to the appropriate wiring diagram. Ensure that all earth connections
are made. See section 9.
8.3 If the fan is being used through a speed regulation device, please refer to
the relevant control device instructions or contact Hydor.
8.4 Check that the motor amperage draw does not exceed the nameplate
rating.
8.5 Means for electrical disconnection must be incorporated in the wiring
installation in accordance with the relevant wiring and electrical
regulations.
8.6 The capacitor should be installed as per the electrical drawings shown in
section 9 for single phase installations.
8.7 Ensure that all earth connections are made. Means of electrical
disconnection must be incorporated in the wiring installation in
accordance with the relevant wiring and electrical regulations.
WARNING: The fan(s) must be isolated from the power supply during
installation and maintenance.

10. Troubleshooting
10.1 Should the unit trip out, check the motor current or connections as an
overload condition has occurred, indicating misconnection, faulty motor
or capacitor (on single phase models), or a jammed impeller.
10.2 If the unit airflow direction is incorrect at initial start-up, re-check the
electrical connections for the desired connection.
10.3 If the unit is slow to start or will not start, it is likely that the capacitor needs
replacing (on single phase models).
11. Maintenance
11.1 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, motor or guards should
be removed using a non-abrasive cleaner. Failure to keep the unit clean
can lead to overheating and damage which is not covered by the warranty.
11.2 All fastenings should be checked for tightness. In addition, all rotating
items should be checked.
11.3 Bearings are of the ‘sealed for life’ type and will not need a detailed
inspection.
