     Installation

NOTE:

 These instructions must be carefully followed to 

assure that your Helos 100 is safely installed. Study them 
thoroughly before installing your Helos 100.

NOTE:

 The following instructions assume the mounting 

surface is of standard wood frame and standard sheet 
rock construction. If you wish to mount the Helos 100 to 
another type of material, you should consult a bonded 
contractor.

Warning!

 Before installing check 

local building codes to verify com-
pliance with local regulations.

Warning!

 Before installing check 

for obstructions behind the drywall 
(electrical,  plumbing  and  other 
fixtures). To do this make a small 
hole, cutting at a 45° angle (this 
will make the hole easier to patch 
if obstructions are found). 

Only 

cut the mounting hole after 
you have verified there are no 
obstructions behind the wall .

Stud finder
Sharp pencil or pen
