Manual Operation; Fit The Steel Reinforced Nylon Racks - Kenner KND800 User Manual

Prior to installing the opener, you should have
or build a concrete pad to support the base plate
of opener in order to maintain proper stability.
The installation proceeds are as follows:
1. Dig a hole for a concrete pad which should be
approximately 40 x 24 x 30cm (16"x 9.5"x 12").
It may protrude 10 cm (4") above ground and 20
cm (8") in depth underground. Increase the pad
height if necessary to protect the system from
flooding, heavy snow etc.
2. Prepare one or more conduits for the electrical cables before pouring concrete. Remember that cable
conduits have to pass through the hole in the opener base.
3. Pour concrete and before it starts to harden, check that it is parallel to the gate leaf and perfectly level.
4. Make sure the positions of the expansion tubes are placed according to the position of mounting holes on
the opener base.
5. Mount the opener to the concrete Pad. This is a temporary installation. Further adjustment will be
required when installing the rack.

Manual operation

You can open the gate manually during a power failure. The opener should also be put in the manual
(emergency release) position before fitting the rack, and installing the opener and limit switch. The process
is as follows:
Insert the release key and turn it 90° clockwise, then pull the release handle outwards 90° to disengage the
clutch between the gear shaft and motor. Now the opener is in manual operation mode.

Fit the steel reinforced nylon racks

1. Start with gate in closed position
2. There are four nylon racks which are each one meter in length. (You can order extra racks from your dealer
if necessary)
3. Place one end of a rack on the gear of the opener as a temporary support.
Make the rack level and mark the mounting holes of the rack on the gate. (four holes for light duty or six
holes for heavy duty)
4. Fit the rack by self-threading screws. This kind of nylon rack is quieter and allows height adjustments to
be made even after it has been fixed. Please keep 1.0mm space between the rack and the gear to avoid the
weight of the gate acting on the opener.
