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 i-HP units are designed for outdoor installation and for places not directly accessible to unqualified 

personnel. 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 repair. 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.

The top part and discharge pipes of the compressor operate at high temperatures. Be sure to let the unit to become 

cool before beginning any maintenance work. 

Be careful to the surface of the driver boards’ heatsinks which could be too hot. 

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. 
It recommended not to remove/tamper with the safety pressure switch and its connections in order not to endanger 

its functionality as safety device. Burst risk.
