Lubricate all movable parts with a light oil after fitting,
each Spring and as required during the Summer. Apply
petroleum jelly to the cylinder thread occasionally.
It is recommended that your window opener - or at least
the cylinder - is removed from your greenhouse for the
Winter. Store it in a dry place and do not forget to lubricate particularly the piston rod before remounting in
the Spring. Check that the piston rod moves smoothly.
Your automatic window opener is guaranteed for a
periode of 1 year from the date of purchase provided
that it has been fitted an maintained in accordance with
the instructions.
1. Check that the greenhouse window opens freely and
is not obstructed.
Remove existing casement stays and arms from the
window and frame.
2. Fit the opener onto the window and its outer
2a. On most greenhouses made out of aluminium
Fitting is done using the enclosed clamps (11)
– se Fig.3. Fit one clamp loosely onto the windowbracket (10) of the opener using the enclosed screws. Choose the most suitable holes
on the sillbracket of the opener and fit the second clamp onto this. Make sure that the upper
edge of the sillbracket 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 instructtions outlined under pos. 3-4-5-6
2c. On aluminium-greenhouses where our clamps
do not fit, read the manual supplied by the
greenhouse manufacturer – and then follow
our instructions mentioned under pos. 3-4-5-6
3. Insert the piston rod (2) on the cylinder (1) into the
push-rod (4), and align the hole at the end of the
piston-rod with Hole A in the push-rod, and lock it
by inserting the small hairpin (5) – see Fig.5.
4. Tighten the sillbracket of the opener onto the centre of the windowsill – see Fig.6.
5. Tighten the windowbracket onto the windowframe
right above the sillbracket. 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 (3). Then wind the cylinder on until
equally much of the cylinders thread is visible on
either side of the cylinder housing – see Fig.7.
7. Check if the window can open freely as much as the
opener allows it to. If not, the opening width of the
window opener should be reduced.
A. The opening width can be obstructed at a width
of 32 cm (appr. 12½”) by inserting the big hairpin
into hole C on the arm called K (7) and locking the
push-rod to the piston-rod using hole B.
B. By assembling the piston-rod and push-rod in hole
B, a small reduction of the opening width is gained,
at the same time as the start-opening temperature is
delayed. If the thread of the cylinder has just been
entered a few rounds into the cylinder housing –
and the locking is made using hole B – the opener
begin opening at appr. 28°C.
Draw back the thermometer cover (13) without turning
it and without removing it completely from the thermometer. See Fig 8.
Read the thermometer and put back the cover. The
thermometer must always be protected by the cover as it
does no stand light very long.
In order that your vent control should start opening the
window at a different temperature, adjustment can be
made by turning the cylinder:
One complete turn corresponds to approximately
