QAD#IM6010 RevD 11.01.19
Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The heater integrated in the control
unit prevents this in general.
Manual Hand Wheel and Lever
HQ actuators are provided with a manual operation system.
The HQ006 actuator comes standard with a manual override nut.
This is located on the bottom of the unit, and can be easily operated with a 5M wrench.
Turn the hand wheel until the valve reaches the required position
Turn clockwise to open and counter clockwise to close
When nut becomes tight
DO NOT FORCE
further as this will cause serious damage to the gearing.
CAUTION:
The manual nut is to facilitate the setting up of the actuator drive to the valve shaft at time of assembly or to drive the
valve to a fail safe position in the event of power failure.
It is NOT designed to free up a jammed valve. Using the manual nut
when the valve is tight or jammed will damage the gears and void any warranty.
To free up a tight or jammed valve you must remove the actuator from the valve, using a spanner directly on the valve shaft, rotate
until it turns freely.
If the torque required to move the valve is greater than the rated output torque of the actuator the unit will not operate.

Note:
The override engagement lever returns automatically to auto position when the actuator is operated electrically.
Lubrication
HQ is a totally enclosed unit with a permanently lubricated gear train (Moly EP Grease). Once installed lubrication should not be
required. However, periodic preventative maintenance will extend the operating life of the actuator.
