Holes
The HT 8 consists of a double-walled housing with upper shell ① and lower shell ③
On the lower shell, the HT 8 has three small holes ②. These drill-holes are attached for the 
purpose of diverting the liquid that can penetrate into the space between the double-walled 
housing if the malleable protective shroud on the upper shell is pushed through.
