INFORMATION FOR SAFE INSTALLATION, OPERATION
AND MAINTENANCE OF NUAIRE VENTILATION EQUIPMENT
To comply with EC Council Directives 89/392/EEC Machinery Directive
& 93/44/EEC Amendment to the Machinery Directive.
To be read in conjunction with the relevant Product Documentation (see 2.1)
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, please 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 in particular 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 eg. 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 ductwork systems. They must not be used to support
the ductwork.
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 (eg 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.
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 minium 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.
