Please make sure that no humidity may penetrate
the vacuum tubes/collector housing. Do not install the
collector during humid conditions or in rain.
Disposal
The collector contains harzardous waste. Dismounted col-
lectors can be returned to the manufacturer Oventrop. They
will be disposed of professionally.

3.3 Heat transfer liquid for a frost-free operation of
the solar plant
To guarantee a perfect operation of the solar plant and to
prevent freezing of the plant at temperatures below zero,
the heat transfer liquid "Tyfocor LS" available from Oven-
trop has to be used.
The heat transfer liquid is available separately.
Item no.: 136 16 90 = "Tyfocor LS", 10 l canister
Item no.: 136 16 91 = "Tyfocor LS", 25 l canister

4 Roof installation of collector

1. Mount roof hooks according to illustr. 6 and fix them
on rafter using wood screws. Provide for a sufficient
anchorage of the roof hooks at the roof construction.
Due to the total load in regions with high snow and wind
load stressing, the installation must be approved by a
structural engineer.
Illustr. 6: Fitting of roof hooks (Illustr. roof hook item no.
136 12 62)
2. Fit mounting rails onto the roof hook. The mounting
rails can be fitted onto the roof hooks from below or lat-
erally with the help of a sliding block (see illustr. 8 and 9).
The sliding block must introduced into the mounting rail
(see illustr. 7).

3. Fit mounting rails onto the roof hook. Tightly screw
roof hook to the sliding block with an M8 screw.
