Installing the Optional 9033 Univent Automatic Opener
The original Univent instructions are included with the 9033 Univent Automatic Opener, but have
limited usefulness as our application is slightly different.
Univent Adjustment
-
the only adjustment is the threading in or out of the cylinder –
with the
temperature cool enough so you
’
d like the door to be closed, adjust the cylinder until the top cover
begins to open. This sets the temperature that the cold frame will open for ventilation.
Step 1 Univent Assembly
1.
Remove the Univent from the box and open the plastic bags of parts.
2.
This step is also explained on the Univent instruction sheet should you have any questions.
Take the black cylinder and thread it into the holder, lining it up with the sleeve at the same time.
Thread it only a few turns, not all the way. Find the smaller of the wire clips and insert it thru the hole
in the sleeve and piston rod. Use the hole closest to the end of the piston rod. Push it firmly in place
so it won
’
t fall out.
Step 2 Mounting Plate Assembly
On the inside of the front panel locate the center of the top
board. Attach the mounting plate with the top of the plate 1
1/8”
from the top of the board like the picture to the right.
Step 3 Attaching the Automatic Opener to Top Cover
Turn the cover over and locate the center board of the top
cover. There is a mounting plate already attached to the
automatic opener. Attach the mounting plate to the center
board 1
11/16”
from the front edge of the top cover as shown
in the picture on the right.
Step 3 Attaching the Automatic Opener to Front Wall
Squeeze the mounting arms together and slide it onto the
mounting bracket as shown in the picture to the right and in-
figure #7 of the Univent instructions.
