INSTALLATION 

 

WARNING:  All  the  operation  described  in  next  chapters  MUST  BE  DONE  BY  TRAINED  PEOPLE  ONLY.  Before  any 
operation on the unit, be sure that the electric supply is disconnected. 

5.1

 

GENERALITY 

When  installing  or  servicing  the  unit,  it  is  necessary  to  strictly  follow  the  rules  listed  in  this  manual,  to  conform  to  all  the 
specifications of the labels on the unit, and to take any possible precautions. Not observing the rules reported on this manual can 
create dangerous situations. 

 

After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition; any eventual 
damage has to be questioned to the carrier and recorded on the Delivery Note before signing it. 

The company has to be informed, within 8 days, of the extent of the damage. The Customer should prepare a written statement of 
any severe damage. 

 

WARNING: The units are designed for outdoor installation. The place of installation must be entirely far away from 
fire risk. All the necessary measures should be adopted in order to prevent the fire risk in the place of installation. The 
outdoor ambient temperature shall not exceed 46°C. Above this value, the unit is no longer covered by the directives 
in force in the area of pressure equipment. 

 

WARNING: The unit should be installed so that adequate clearance is available for maintenance and repairation. The 
warranty does not cover costs related to platforms or handling equipment necessary for any maintenance. 

 

All maintenance and testing operations should be carried out only by QUALIFIED PERSONNEL. 

 

Before any operation on the unit, make sure the power supply is disconnected. 

 

WARNING: MOVING PARTS, RISK OF DEATH. 
Disconnect the power supply and ensure that the fan is stopped before opening the front panel. 

 

The temperatures of heads and discharge piping of the compressor are usually high. 

 

Be careful when working near condensing coils. 
The aluminum fins are very sharp and can cause serious injuries. 

 

After the maintenance operations, close the panels tightly with the fastening screws. 

5.2

 

LIFTING AND HANDLING 

When unloading and installing the unit, it is highly recommended to 
avoid  any  sudden  move  in  order  to  protect  the  inner  components. 
Units can be lifted by means of a forklift or, in alternative, of belts, 
being  sure  not  to  damage  the  lateral  panels  and  the  cover.  It  is 
important to keep the unit horizontal during these operations. 

 

5.3

 

LOCATION AND MINIMUM TECHNICAL CLEARANCES 

The all HP_OWER  units are designed for outdoor installation: any cover over the unit and location near trees (even if they partially 
cover  the  unit)  has  to  be  avoided  in  order  to  prevent  air  recirculation.  It  is  advisable  to  create  a  proper  basement,  with  a  size 
similar to unit foot-print. Unit vibration level is very low: it is advisable however, to fit a rigid rubber band between basement and 
unit  base-frame.  It  is  also  possible  to  install  anti-vibration  supports  (springs  or  rubbers)  to  keep  vibrations  at  a  very  low  level. 
Absolute care has to be taken to ensure adequate air volume to the condenser. Re-circulation of discharge air has to be avoided; 
failure to observe this point will result in poor performance or activation of safety controls. For these reasons it is necessary to 
observe the following clearances:
