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 Procedure 

 

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 the supplier for advice. 

 

SPECIAL NOTE 

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