PLEASE NOTICE :
1. Your automatic window opener is NOT suitable for use where the
temperature will exceed 50°C / 122°F.
2. Ensure that your greenhouse window is able to open - and is not
obstructed - otherwise damage may occur.
TECHNICAL DATA:
A: Maximum window opening is approximately 45 cm / 18 inches
B: Maximum opening at 30°C / 86°F depending on load and adjustment
C: Suitable for greenhouse vents weighing up to 15 kg / 33 lbs
D: Your automatic window opener can be adjusted to start opening at
temperatures between 15-25°C / 60-77°F
COMPONENTS:
See Fig.1

width

MAINTENANCE:
Lubricate all movable parts using a light oil : after tting – each spring – and
as required during the summer.
Apply petroleum jelly to the cylinder thread occasionally.
WINTER STORAGE :
Remove the entire opener - or the cylinder only if this is easier. Store it in a
dry place during the winter. Remember to lubricate the piston rod and the
cylinders thread before remounting the following spring. Check that the
piston rod moves smoothly !
GUARANTEE
A correctly used opener is guaranteed for 1 year provided that it has been
tted and maintained in accordance with our instructions.
FITTING INSTRUCTION:
Place the cylinder (part no 2) in a cool place (cold water or refrigerator) for at
least 30 minutes at max. 10°C.
1. Check that the window in the greenhouse / cold frame opens freely and
is not obstructed. Remove existing casement stays and arms from the
window and from the sill.

2. Ways of tting the opener onto a greenhouse window and its sill :
2a On most greenhouses made out of Aluminium tting is done using
the enclosed clamps (part no 11)– see Fig.3. Fit one clamp loosely
onto the window brackets (part no 10) of the opener using the
enclosed screws – see Fig.2. Choose the most suitable holes on the
sill bracket (part no 9) of the opener, and t the second clamp onto
this. Make sure that the upper edge of the sill bracket is as close as
possible to the edge of the windowsill.
2b For greenhouses made out of wood get some screws for wood, and
then follow our instructions outlined under pos. 3-4-5-6-7
2c For Aluminium greenhouses where our clamps do not t, read the
manual supplied by the greenhouse manufacturer – and then follow
our instructions outlined under pos. 3-4-5-6-7
3. Insert the piston rod (part no 2) of the cylinder (part no 1) into the clutch
T (part no 4) and align the hole at the end of the piston rod with hole A
in the clutch T – and lock it by inserting the small hairpin (part no 5) – see
Fig.4.
4. Tighten the sill bracket of the opener onto the center of the windowsill -
see Fig.6
5. Tighten the window bracket onto the window frame right above the sill
bracket. The window must remain closed during this operation.
6. Open the window just enough to allow the thread on the cylinder to
catch the thread inside the cylinder housing (part no 3). Now wind the
cylinder on until equally much of the cylinders thread is visible on either
side of the cylinder housing – see Fig.5
7. Check if the window can open freely as much as the opener allows it to. If
not, the opening width of the opener should be reduced.
