INSTALLING THE HEPA FILTER (OPTIONAL) 
The air conditioner can accommodate a HEPA filter which will purify the 
air expelled back into the room in any operating mode. These can be 
purchased from the stockist using the code: FIL-ECOSILENTHEPA. 
The HEPA filter should be unwrapped and installed in the upper air inlet. 
To install, remove the upper filter frame from the air conditioner by 
pressing the two clips on the top of the filter frame. Place the HEPA filter 
within the filter frame before refitting onto the unit. 
In order to maintain performance, the filter should be regularly 
vacuumed. The filter should be replaced every six months, depending on 
usage and air quality. 
NOTES: 
•  The window kit is only designed to be installed with sliding or sash windows or doors. The window 
kit is not designed or to be used with any other style of windows.  
•  The fish tail adaptor can be used without the slide bar with most windows / doors.  
•  When using the air conditioner ensure that the opening left around the fishtail is as small as 
possible as the cooling will be less efficient.  
•  The best form of installation is through a wall duct. By properly venting you expel hot air from your 
room while efficiently cooling it.  
•  Your air conditioner should be used without the vent pipe in dry mode. When using dry mode 
ensure that an external water tank is used, monitored and regularly emptied before overflowing. 
Permanent plumbing can be also installed for dry mode or an external uplift water pump can be 
set up for unattended use.  
IMPORTANT SAFEGUARDS 
The length of the soft hose extends from approximately 35 cm to 200 cm. If hose is extended above this 
length, the unit may malfunction which can invalidate the warranty. The outlet vent must be well ventilated 
and not obstructed as this will cause the unit to overheat. Keep the hose as straight and short as possible 
and avoid bending the air hose by more than 30 degrees in order not to reduce the performance of the 
unit.
