"MACKRIDGE AND KENSTACK" ROOF VENTILATORS
OPERATION, SERVICE AND MAINTENANCE SCHEDULE
GENERAL DESCRIPTION
Mackridge and Kenstack Roof Ventilators can be either ridge (Mackridge) or slope (Kenstack) mounted. The units can be supplied with or without
an internally mounted operating damper, controlled by a series of options, ie: manual cable operation, pneumatic controls or electric actuators.
TESTING
Where the unit is part of a system providing day-to-day ventilation only, we recommend that the units be tested on a monthly basis.
Units should not be left for long periods without testing as this may affect the functioning of the unit.
OPERATING INSTRUCTIONS (TESTING ONLY)
ELECTRO-MAGNET TYPE
TO OPEN: Interruption of the power supply will cause the damper to open by the action of the internally mounted springs.
TO CLOSE: Reinstate the power supply, then pull down on re-set cable until the magnet faces meet and the louvres stay closed.
Note: Care must be taken to ensure that the manual reset cable is unobstructed and free running.
230 VOLT-24 VOLT MOTOR
TO OPEN: Interruption of the power supply will de-activate the electro-magnet built into the tubular motor, thereby allowing control cable to unwind
and the damper to open by the action of the internally mounted springs attached to the control bar.
TO CLOSE: Re-instate the power supply and then turn the operating switch to the “close” position. This will re-activate the magnet contained in
the motor and the motor will activate and rewind the control cable to close the damper. (The motor will stop turning when the control bar makes
contact with the limit switch). 24 volt supply must be maintained to hold blades in the closed position.
MANUALLY OPERATED (CLAM CLEAT)
TO OPEN: Pull cord/cable in a downwards and outwards direction to disengage the clam cleat cable grip and release the cable to open the unit.
TO CLOSE: Pull cord/cable in a downwards direction until damper is closed then allow cord/cable to engage into the clam cleat assembly to hold
the damper in the closed position.
OPERATING CABLE - IMPORTANT
Care must be taken to ensure that the manual operating cable is installed in accordance with our recommended fixing instructions and is
unobstructed and free running. Pulleys must be used when direction of cable run is changed, with number of direction changes kept to
a minimum with no acute angles.
PNEUMATICALLY OPERATED
TO OPEN: Turn control panel switch to open.
TO CLOSE: Turn control panel switch to close.
ELECTRIC ACTUATOR
TO OPEN: Turn switch on control panel to “open”.
TO CLOSE: Turn switch on control panel to “close”.
MANUALLY OPERATED (WINCH TYPE)
TO OPEN: Turn handle anti-clockwise.
TO CLOSE: Turn handle clockwise.
RESET CABLE - IMPORTANT
Care must be taken to ensure that the manual reset cable located on units with electro-magnet controls, is unobstructed and free
running. The cable must not be tied to the wall or restricted in any way which may prevent the unit opening.
OPERATING INSTRUCTIONS (DAY TO DAY USE)
ELECTRO MAGNET CONTROLS
NOT RECOMMENDED FOR DAY TO DAY USE
240 VOLT-24 VOLT MOTOR
TO OPEN: Turn the control switch to the “open” position and the motor will operate allowing the damper to open on the internally mounted springs.
The motor will automatically stop at the fully open position when the limit switch is activated.
TO CLOSE: Turn the control switch to the “close” position and the motor will close damper. The motor will automatically stop when the damper
are in the closed position.
Note 1: The damper may be held in any position between fully open and fully closed on either the opening cycle or closing cycle.
The closing procedure is as previously described under the “close test” heading.
MANUALLY OPERATED –(CLAM CLEAT)
TO OPEN: Pull cord/cable in a downwards and outwards direction to disengage the clam cleat cable grip and release the cable to open the
damper.
TO CLOSE: Pull cord/cable in a downwards direction until the damper is closed then allow cord/cable to engage into the clam cleat assembly to
hold the damper in the closed position.
MANUALLY OPERATED (WINCH TYPE)
TO OPEN: Turn handle anti-clockwise.
TO CLOSE: Turn handle clockwise.
PNEUMATICALLY OPERATED
TO OPEN: Turn control panel switch to open.
TO CLOSE: Turn control panel switch to closed.
Note: If units are “failsafe to open”, air supply must be maintained at all times to allow units to close.
If units are “failsafe to close”, the units will automatically return to the closed position.
ELECTRIC ACTUATOR
TO OPEN: Turn switch on control panel to “open”.
TO CLOSE: Turn switch on control panel to “close”.
MAINTENANCE
APPLICABLE FOR ALL CONTROL OPTIONS –MACKRIDGE/KENSTACK
1. Check the fixings securing the ventilator and all ventilator fastenings/nuts/bolts/springs etc.
2. All internal drainage channels should be inspected and debris removed to ensure correct drainage and weathering.
3. Ensure that no foreign objects are interfering with the operation of the unit.
4. Reset cable –on units operated by electro magnets, ensure the reset cables are free running and not tied off or restricted.
CLEANING IN SITU
It is the responsibility of the customer to ensure that the goods are properly maintained.
THE USE OF ABRASIVE, POLISH OR CLEANERS SHOULD NOT BE USED.
STRONG SOLVENTS SHOULD NOT BE USED FOR CLEANING COATED SURFACES UNDER ANY CIRCUMSTANCES.
Clean off any dirt/debris using a mild detergent and warm water using a sponge or soft cloth and, if required, a stiff (not wire) brush. The use
of chemicals should be avoided.*
*See paragraph below if units are finished in polyester powder coating.
CLEANING POLYESTER POWDER COATINGS
PPC products should, under NO CIRCUMSTANCES, be cleaned using abrasive cleaners, strong solvents, strong alkali or acid material or cutting
and abrasive polishes.
The coated products should be cleaned at periods not exceeding 12 months. In HIGHLY POLLUTED AREAS this interval should be reduced to 6
months.
Cleaning should take place using water containing a mild cleaning solution. This is to be applied using a soft brush, sponge or chamois leather.
HARD SCRUBBING MAY DAMAGE THE PPC.
ANY DAMAGED AREA MUST BE CORRECTED IMMEDIATELY.
SERVICING
It is recommended that, after installation, the ventilators should be serviced at least once a year. The frequency may have to be increased subject
to the type of environment. This work to be carried out by a suitable qualified technician and any repairs or modifications reported. After carrying
out the service work, the whole system should be tested to ensure that it operates in accordance with the specification for the project.
Cleaning and/or maintenance should be undertaken by a responsible contractor. It is the responsibility of the contractor to apply all necessary
safety procedures under the relevant CDM requirements.
