January2005:  E\Manuals\Others\Qualitair\ICC\0412115B  

 

 

 

 

 

 

1. INSTALLATION & SAFETY 
 

1.1 Installation 

 

The units making up the Air Conditioning System must only be installed by a qualified engineer, 
following the mandatory and local codes of practice. 

 

1.2 Handling 
 

Care must be taken when the units are moved or lifted to ensure that everyone and everything is 

safe. When lifting equipment is used, it must be suitable and approved. 
 

1.3 Application 

 

Ensure that the unit is only used for suitable purpose/application. 
 

1.4 Electrical Connection 

 
Electrical work and connections must only be made by authorised electricians, in accordance with 

mandatory regulations and local codes of practice. 

 
1.5 Warranty 

 

Failure to comply with the manufacturer’s installation instructions could affect the performance of the 

unit and invalidate the warranty.  Warranty is also subject to the implementation of a planned 
service/maintenance agreement as documented in the warranty booklet supplied with the unit. 

1.6 Safety Procedures 
 
General 

1.

 

All works must be carried out in accordance with the manufacturer’s installation and operating 

procedures. 

2.

 

Good working practices must be followed at all times so that Mechanical and Electrical hazards are 

kept to a minimum. 

3.

 

The equipment has been fitted with doors and covers to prevent access during operation. These 

must be kept in place and additional guards fitted, if necessary. 

4.

 

The equipment must be connected to an external electrical isolator if one is not supplied fitted to 

the unit. 

5.

 

Servicing and maintenance must only be carried out by fully qualified and competent staff.  Before 
any work is started, electrically isolate the units to make sure that they cannot be switched on 

accidentally and allow sufficient time for isolated parts to come to rest before removing panels.  

Electrical isolation switches must be labelled to show that they are OFF during servicing and 
maintenance operations. 

Note: 

Some units are dormant in standby mode and can restart without warning if they are not 

electrically isolated. 

6.

 

Care must be taken not to touch components or pipework which may be extremely hot or cold, for 
a period after the unit is electrically isolated. 

7.

 

After completing any tasks ensure all guards, covers and doors are correctly refitted before 

restoring the power supply to the unit. 

8.

 

Air conditioning equipment may generate unacceptable noise levels. If noise levels are 

unacceptable sound and vibration attenuators may be required.  For noise level guidance refer to 

technical literature, or contact Qualitair, or their distributors for advice. 

 

SPECIAL NOTE 

IF ANYTHING IS NOT CLEAR, PLEASE CONTACT YOUR DISTRIBUTOR FOR CLARIFICATION.
