1. GENERAL INFORMATION
The Sectional-500/DIY-500 electromechanical chain operator is designed for automation of residential sectional doors.
It consists of a mechanical gear and an electric engine with a built-in control unit. The gear and the electric engine are
incorporated into a housing.
It consists of an electromechanical motor reducer, an electronic control unit and an illuminating lamp, incorporated into
a housing. The electric operator is easily secured on a track and mounted to the ceiling, opening of the doors is carried out by
means of a chain/belt gear. The self-locking operator gear ensures mechanical interlocking of the doors, if engine is not functioning,
but in the absence of electric power the manual emergency release allows you to open and to close the doors manually.
For maximum safety, the control unit has force protection.
Besides, optionally, the operator can be equipped by electronic protective sensors, which stop the doors closing, if there are
obstacles or people within the operating range of automatic system.

2. SAFETY INSTRUCTIONS
IMPORTANT! You should observe the safety regulations to preserve people’s health. You must keep the present Manual.
 You should follow all the recommendations of the given Manual, as incorrect equipment installation could lead to serious
damages.
 The Sectional-500/DIY-500 operator is designed for automation of residential sectional doors. It should be used only for
the purpose intended; any other use is forbidden.
 DoorHan is not liable for personal injuries, if the product was used for purposes other than intended.
 Make sure that the doors are balanced and function smoothly before installing the operator.
 The installation is to be carried out according to the standards EN 12453 and EN 12445. For providing the required safety
level, these requirements should be observed in non-EU countries.
 You should check if the doors conform to the standards EN 12604 and EN 12605 (see documentation on the doors). For
non-EU countries these measures are to be observed for ensuring the normal safety level.
 The mechanical door assembly units must conform to the provisions of the standards EN 12604 and EN 12605.
 Before installing the operator, make sure that the mounting location by its climatic conditions corresponds to the
operator’s specifications.
 You should not install the equipment in rooms with highly flammable substances or other hazardous media, as this can
result in explosion or fire.
 You should use tools, indicated in Section “Tools” of the given Manual, during assembly, installation and adjustment
of the operator.
 You should use a stable support when working at height.
 The operator is allowed to install at more than 2.5 m height.
 You should use hand and face protection when drilling holes.
 You should use metal goods from the operator package or other goods equivalent to them for fastening the product.
 You should power off when performing installation, cleaning or maintenance of the operator.
 When mounting the operator on doors with the infitting pass door, it is necessary to install an additional safety device,
which prevents the operator activation, when the door is open.
 Make sure, that there will not be trapping of articles between movable and fixed elements of the operator when the doors
move.
 You should use additional DoorHan accessories, since the accessories of third party manufacturers can damage the
automatic system.
 DoorHan is not liable for unstable work of the automatic system, if you use safety devices and accessories, produced by
other manufacturers without securing approval of DoorHan.
 You should not leave electric engines in a released state. This can lead to uncontrolled movement of the door wings and,
as a result, to their damage.
 You should not use the operator, if it is necessary to repair or to adjust the equipment, since defects during the assembly
of the operator or incorrectly installed doors can result in injury.
 DoorHan is not liable, if the product is not correctly installed or is damaged during operation.
 The electric operator is not equipped with the stationary power cord; therefore mains supply is to be fed to the automatic
system via an automatic switch with a distance between the adjacent contacts minimum 3 mm. It is recommended to use
double pole circuit breaker 10 A.
 Make sure, that there are no foreign bodies within the operating range of the electric operator before its start.
 You should not introduce changes, not stated in the given Manual, into the automatic system.
 You should remove the product package and dispose of it. You should not leave the packaging materials within the reach
of children.
 You should not allow children to play in the door movement area during the operator operation. All remote control panels
and also stationary control buttons must be absolutely inaccessible for possible use by children.
 It is allowed to drive in and to pass only when the doors do not move and the operator is switched off.
 The contents of the Manual could not serve as a basis for laying claims of any kind.
 The manufacturer reserves the right to introduce modifications into the structure and to improve it without prior notice.
IMPORTANT! For safe and correct work of the operator it is necessary to install a mechanical stop to limit the door leaf
motion.
