Special warning 

To ensure the actuator complete unit’s outer housing properties, during adjustment and maintenance, the 

user should operate according to the operation manual and this special warning! If the user does not operate 

correctly or does not operate according to the operation manual and special warning and causing the actuator 

out of the factory, all the parts related to outer housing protection have been inspected strictly and be ensured 

to be well sealed. If the user open the following parts due to the needs of adjustment or maintenance: 

control box cover 

wiring box cover 

wire outlet assembly 

after opening, the user must ensure: 

during the operation of adjustment maintenance or some needed, at that time the actuator does not have the 

precious protection properties, the user should ensure that it is kept from the invasion of rain, snow, hail, 

moisture, dust and so on. 

after operation, when the cover is put on or the wire outlet is tightened, the user should ensure that the opened 

parts inside does not have any disadvantage elements such as water, dust moisture that may led to the 

protection properties damaging. 

after operation and the cover is put on, the user should ensure that all the fixing screws and the flat spacer and 

spring spacer on the box cover should be tightened, with no phenomenon of leakage or loosening. at the 

same time, the user should ensure that the rubber sealing ring which function as sealing part at the 

contacting part of cover box and housing, does not be damaged and be painted calcium grease, and then 

assemble as previous. 

after the wire pass through the wire outlet, the user should ensure to tighten the tightening nut, to ensure 

sealing. The screw sealing between the tightening nut and housing must have PTFE. At the same time, the 

cable and tightening nutinner holes must be painted sealing (such as 609). 

if other parts such as position window or local button, is opened due to some causes. And reassembled, the 

user should ensure that the sealing is not affected with disadvantage.
