PLANNING
WARNING
The door guides must be fitted with mechanical stops
that prevent the bottom rail from passing through in
the opening direction. The opener should stall if driven
into the mechanical stops
.
Identify the type and dimensions of your commercial rolling door. A check of the application is recommended to ensure suitabil-
ity of the opener model to the door.
Installer is to check that the temperature range marked on the drive is suitable for the location.
Note: 2.0 openers are not recommended for use on residential garage doors
.
* Door size is stated as a guide only. Refer to "max door mass" to assess drive suitability.
** Maximum door mass is:
- before spring balancing. Door must be spring balanced.
- based on at least 4:1 sprocket ratio, and curtain load with 200mm drum diameter.
If any conditions above are not met, some consideration should be given to increasing the sprocket ratio, or opener size. The
opener should be installed on the most suitable side of the commercial door. Consider an In-Board Mounting Kit (P/N IBMK) if
there is insufficient side room. Select the side that meets the requirements listed below.
Must have minimum distance of 15mm between mounting plate and door drum sprocket (refer pg 6 image no. 1)
Must have minimum distance of 10mm between APE housing and imposing structure (refer pg 7 image no. 4)
Must have minimum overhead clearance of 150mm from the main control housing (refer pg 7 image no. 5)
Note: Before installing the opener, check that the commercial door is in good mechanical condition, correctly balanced and
opens and closes properly.

Doors of Rigid Construction
When using a Grifco® 2.0 on commercial doors of ‘rigid’
construction (eg. bi-fold, vertical lift, sectional or continuous
steel roller doors etc.), consider that the
limit confirmation
movement requires a 1/4 turn of the output shaft downward at
the closed position (refer to page 12 for more information on
how to reset the re-find movement). Sufficient mechanical free-
dom must be provided at the closed position for this
reason.
