Installation and Maintenance Instructions:
Maintenance
1.Once the unit has been correctly
fitted it is recommended that
periodic checks (every six
months) are carried out to ensure
all fixings are tight and the door
closes freely and positively into
the frame, without slamming.
2.A light oil lubricant (non-graphite)
should be applied to the moving
joints and exposed pivot points.
After Installation
1.When the closer operates to close
the door from its maximum opening
position, it should ensure the lock
latchbolt and any seals are overcome
and the leaf returned into its frame.
2.When the door is slightly open and
the latch bolt resting against the
strike, release the door to ensure the
leaf fully closes into its frame.
Warning
1.Please note the minimum power size requirement for fire / smoke
door assemblies is 3 as required by Approved Document B.
2.Do not install mechanical hold open devices on fire / smoke door
assemblies.
3.Take care not to exceed the maximum opening angle as detailed
above.
4.Care and attention must be taken when adjusting any of the units
control valves to avoid damage through over adjustment.
5.All Synergy Door Closer units are sealed for life and the internal
components assembled under high load, therefore, tampering
with the mechanism is to be strictly avoided.
Installation Instructions: Please refer to actual size template for exact fitting dimensions
Fixing in Fig.1 / Fig.61
Pre-Loading of Arm
For the unit to provide the optimum performance and overcome any resistance
upon closing it is recommended that the armset is “pre-loaded” To pre-load,
reposition the fixing angle of the arm onto the mechanism so that the end of the
closing cycle would be past the stop position, as indicated below.
Adjustment Details
After installation check the operation of the door closer. Adjustment to the
operation of the unit is made by altering the two valves at the front of the
mechanism. PLEASE NOTE each valve is at its fastest speed with the adjustment
of 1 full turn.
The following adjustment valves have a maximum adjustment of 1 full turn per
valve.
PLEASE NOTE
over adjustment will damage the mechanism and/or the
performance of the door closer and invalidate its guarantee.
Adjust the optional Backcheck (valve #3) before adjusting the Closing Speed
(valve #1) and Latching Action (valve #2).
