INSTALLATION AND OPERATING INSTRUCTIONS
 

1. Your automatic window opener is not suitable
for use where temperatures will exceed 50C/122F.
2. Ensure that your greenhouse window is able
to open and is not obstructed otherwise damage could occur.

Technical data:

A. Maximum window opening approximately 45cm/18".
B. Maximum opening at 30C/86F depending on adjustment and load.
C. Suitable for greenhouse vents weighing up to 7kg/151b.
D. Your automatic window opener can be adjusted to open at temperatures in the range 15'
25'C/60'-77'F.

Components:
See fig. 1.
1. Cylinder
2. Cylinder housing 3. Piston rod 4. Push rod 5. Hair pin 6. Stop pin 7. Arm b 8. Arm a
9. Frame bracket 10. Window bracket 11. Clamps

Maintenance:

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.

Winter storage:
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.

Guarantee:
Your automatic window opener is guaranteed for a period of 1 year from the date of purchase, provided that it has been fitted and maintained in accordance with the instructions.

Fitting 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. Loosely fit a clamp (11) to the window bracket (10) using two of the screws supplied. See fig. 2. On wooden greenhouses the window and frame brackets can be screwed directly on to the woodwork. See fig. 3.
3. Choose the most suitable pair of holes and loosely fit the other clamp to the frame bracket (9). Ensure the upper edge of the frame bracket is as close to the edge of the window frame as possible. See example in fig. 3.
4. Screw the cylinder (1) into the cylinder housing (2). See fig. 4.
5. Now measure the distance that your window will open.
A. If the window will open at least 42cm/161/2":
Push the piston rod (3) into the push rod (4). The hole in the piston rod should be placed in line with hole a in the push rod, see fig. 1. The hairpin (5) should then be fitted through the holes, see fig. 5.
B . If the window will only open between 30 and 42cm/12" and 16":
Follow the same procedure as described above except use hole b and fit the stop pin (6) on to the arm (7), see fig. 6.

IMPORTANT:

Do not fit the stop pin (6) unless the hairpin (5) is placed in hole b.

6. Now unscrew the cylinder from the cylinder housing. Piston and push rod remain assembled. Pull the cylinder clear of the housing but do not attempt to completely remove the cylinder.
7. Fit the frame bracket to the window sill, see fig. 7.
8. Fit the window bracket to the window frame just above the frame bracket. The window must be in the closed position.
9. Open the window sufficiently to allow you to screw the cylinder into the cylinder housing. Screw in the cylinder until the thread is equal length on both sides of the housing and then release the window.

Adjustment:
In order that your window opener should start opening the window at a different temperature, adjustment can be made by turning the cylinder:
Clockwise to achieve an earlier/higher opening.
Anticlockwise to achieve a later/lower opening.
One complete turn corresponds to approximately 0,5C/1F.

WINTER USAGE: The solar vent openers use a waxy proprietary substance in the vent cylinder. When it is warm, the material expands and contracts to move the vent arm. If it is to cold, the cylinder will not move and in some cases freezing and thawing can cause damage to the unit.
