To comply with EC Council Directives 2006/42/EC Machinery Directive and
2004/108/EC (EMC).

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, 

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 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 

duct work systems.  They must not be used to support the ductwork.

4.4

In the event of RF interference the fan may change speed. This is normal and will 
have no adverse effect on the fan. The speed will return to normal once the 
interference has subsided.

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.

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.
