1.0 SAFETY INFORMATION

The provision of the electrical supply and the connection of the unit to the mains 
must be carried out by a qualified electrician. Ensure that the mains supply (Voltage, 
Frequency and Phase) complies with the rating label.

Isolate from power supply before removing any covers. During installation / 
maintenance ensure all covers are fitted before switching on the mains supply.

All-pole disconnection from the mains as shown in the wiring diagram must be 
incorporated within the fixed wiring and shall have a minimum contact separation of 
3mm in accordance with latest edition of the wiring regulations.

This unit must be earthed.

Ducting must be securely fixed with screws to the spigot to prevent access to live 
parts. 

If the supply cord is damaged, it must be replaced by its service agent or similarly 
qualified persons in order to avoid a hazard. 

When installing the unit, take care not to damage electrical or other hidden 
components – do not drill the unit casing. 

Precautions must be taken to avoid the back-flow of gases into the room from the 
open flue of gas or other fuel-burning appliances. 

The unit must be installed indoors, and away from direct sources of frost, heat and 
water spray or moisture generation. Ambient temperature range -5 to 40 deg C. 

The cooling unit is an electro-mechanical device that contains and uses R407C 
refrigerant. The unit provides cooling in the range of 0.4 to 1.4 kW. The weight of the  
R407C refrigerant is 0.63Kg.

This appliance should not be used by children or persons with reduced physical, 
sensory or mental capabilities or lack of experience and knowledge, unless they 
have been given supervision or instruction concerning the safe use of the appliance 
by a person responsible for their safety. Children shall not play with the appliance. 
Cleaning and user maintenance shall not be carried out by children. This unit contains 
live electrical components, moving parts and refrigerant under pressure. Always site 
out of reach of children and protect from vandalism and accidental damage.
