PRE-INSTALLATION 

 
 
The heat pump should never be stored or installed on its side. Upright 
transportation is recommended. If it becomes necessary to transport the heat 
pump on its side, the manufacturer recommends that the unit be in the upright 
position for a minimum of two hours prior to operation. Failure to follow these 
instructions may result in damage to the heat pump. 
 
After removing the unit from the crate/carton, immediately remove the 

 

panels and inspect for any damage that might have occurred during shipment. 
 
Report concealed damage immediately to the transportation company and 
request inspection. 
 
 
 
The electric power source must be the same voltage and phase as shown on the 
rating plate. Line and low voltage wiring must be done in accordance with local 
codes or the national electric code. 
 
The heat pump must be installed by authorised installation engineers and the 
installation  must follow the applicable local rules and regulations as well, as 
these installation  instructions described in this manual.
