FUSES

 

The system and its supply/interconnecting wiring must be protected by fuses, preferably High Rupture Current (HRC) motor rated types  
(EN60269)  or miniature circuit breakers (EN60898) or local codes having similar time lag characteristics,  that allow starting of the 
compressor yet still afford close overcurrent protection under running conditions. The ratings below are for HRC motor rated fuses.

INSTALLATION of 550 Series CONDENSING UNITS 
 

MCU+ = standard condensing unit + FSC + LP   
 

The installer will require:

 

2 open ended spanners for securing the flare fittings 
A 4 or 5mm Allen Key for the valves (dependant on valve type). 

Note: 

It is easier to fit kits prior to mounting the unit. 

 

 
These units are designed to stand on a flat surface. If the unit is to be wall mounted the following kits are available. 
(TEV cannot accept liability for installers own mounting arrangements). 

 
 
 
 

 
Whether floor or wall mounted, it is essential that the mounting surface is capable of supporting the unit weight.  
Leave space around the unit for air circulation and access for installation and maintenance.
