Prior to fitting the Autovent, the power-tube has to be cooled by placing it in a
refrigerator for approximately 30 minutes. See step# 1. This can be achieved by
either placing the complete Autovent in the refrigerator or by removing the power-
tube and cooling it separately. Removal of the spring clip releases the power-
tube.
When the power-tube is cool, place the steel piston rod, See step# 2, against a
hard surface and push it firmly back into the power-tube. If the power-tube has
been detached from the Autovent, reversing the removal process should refit it. Lift
the Autovent arm with one hand, See step# 3, and slip the threaded steel piston
rod into the brass-knurled adjuster, which is fixed in the swivelling block. The brass-
knurled adjuster will be used later to adjust the vent closing position. see step #4.
Fit adaptor P203, using screws 447X2 to the serrated side of the black tube bracket.
See step#5.
Fit adaptor P204,using screws 447X2 to the arm bracket. See step#6.

IMPORTANT
If you are fitting the Autovent on a new SL Greenhouse please follow steps# 9
and forward.
If you are replacing a manual vent with the Autovent you detach the old vent
handle and brackets. See steps# 7 & 8.
Note
: You should leave the screws connecting the handle in place. Remove only
the nuts. These screws and nuts will be used to connect the Autovent.
Fit the two ends of the Autovent to the vent and to the vent frame. See steps#
9, 10 and 11, using screws 448x2 & 421x2 and nuts 422x2.
Adjust the closing gap using the brass-knurled adjuster.See step# 12.
To assure proper functioning of the vent fit two stoppers P205 at each side of
the vent. Centralize the vent and then insert the stoppers in the groove in the
main beam of your greenhouse. See step#13.
