1.0
GENERAL
1.1
The equipment referred to in this
Declaration of Incorporation
is supplied by Nuaire to be assembled into
a ventilation system which may or may not include additional components. The entire system must be
considered for safety purposes and it is the responsibility of the installer to ensure that all of the equipment is
installed in compliance with the manufacturers recommendations and with due regard to current legislation
and codes of practice.
2.0
INFORMATION SUPPLIED WITH THE EQUIPMENT
2.1
Each item of equipment is supplied with a set of documentation which provides the information required for
the safe installation and maintenance of the equipment. This may be in the form of a Data
sheet and/or Installation and Maintenance instruction.
2.2
Each unit has a rating plate attached to its outer casing. The rating plate provides essential data relating to the
equipment such as serial number, unit code and electrical data. Any further data that may be required will be
found in the documentation. If any item is unclear or more information is required, contact Nuaire.
2.3
Where warning labels or notices are attached to the unit the instructions given must be adhered to.
3.0
TRANSPORTATION, HANDLING AND STORAGE
3.1
Care must be taken at all times to prevent damage to the equipment. Note that shock to the unit may result in
the balance of the impeller being affected.
3.2
When handling the equipment, care should be taken with corners and edges and that the weight distribution
within the unit is considered. Lifting gear such as slings or ropes must be arranged so as not to bear on the
casing.
3.3
Equipment stored on site prior to installation should be protected from the weather and steps taken to prevent
ingress of contaminants.
4.0
OPERATIONAL LIMITS
4.1
It is important that the specified operational limits for the equipment are adhered to e.g. operational air
temperature, air borne contaminants and unit orientation.
4.2
Where installation accessories are supplied with the specified equipment e.g. wall mounting brackets. They
are to be used to support the equipment only. Other system components must have separate provision for
support.
4.3
Flanges and connection spigots are provided for the purpose of joining to duct work systems. They must not be
used to support the ductwork.
4.4
Local Environment - Humidity.
Ambient humidity (the humidity at the unit’s installed location) shall be
within the range: 10 to 95% (for controls, non-condensing). Air humidity (the humidity of
the air passing through the unit) shall be within the range: 10 to 95% (for controls, non-condensing).
5.0
INSTALLATION REQUIREMENTS
In addition to the particular requirements given for the individual product, the following general requirements
should be noted.
5.1
Where access to any part of equipment which
moves
, or can become
electrically live
are not prevented by
the equipment panels or by fixed installation detail (e.g. ducting), then guarding to the appropriate standard
must be fitted.
5.2
The electrical installation of the equipment must comply with the requirements of the relevant local electrical
safety regulations.
5.3
For EMC all control and sensor cables should not be placed within 50mm or on the same metal cable tray as
230V switched live, lighting or power cables and any cables not intended for use with this product.
6.0
COMMISSIONING REQUIREMENTS
6.1
General pre-commissioning checks relevant to safe operation consist of the following:
Ensure that no foreign bodies are present within the fan or casing.
Check electrical safety e.g. Insulation and earthing.
Check guarding of system.
Check operation of Isolators/Controls.
Check fastenings for security.
6.2
Other commissioning requirements are given in the relevant product documentation.
7.0
OPERATIONAL REQUIREMENTS
7.1
Equipment access panels must be in place at all times during operation of the unit, and must be secured with
the original fastenings.
7.2
If failure of the equipment occurs or is suspected then it should be taken out of service until a competent
person can effect repair or examination. (Note that certain ranges of equipment are designed to detect and
compensate for fan failure).
8.0
MAINTENANCE REQUIREMENTS
8.1
Specific maintenance requirements are given in the relevant product documentation.
8.2
It is important that the correct tools are used for the various tasks required.
8.3
If the access panels are to be removed for any reason the electrical supply to the unit must be isolated.
8.4
A minimum period of two minutes should be allowed after electrical disconnection before access panels are
removed. This will allow the impeller to come to rest.
NB: Care should still be taken however since airflow generated at some other point in the system can
cause the impeller to “windmill” even when power is not present.
8.5
Care should be taken when removing and storing access panels in windy conditions.
Note: All standards used were current and valid at the date of signature.
