FITTING INSTRUCTIONS for RC Range of Stop Seals.
The illustration above includes a milled slot as supplied when the holder lengths are specially cut to customers requirements. Standard
lengths do not have milled slots.
POSITION OF SEAL RELATIVE TO THE FACE OF THE DOOR
Blade seals are designed to function correctly when compressed to approx. 1/3rd of their vertical position when fitted. Tubular
seals are normally compressed by 1mm, just sufficient to stop draughts without excessiver resistance. The diagrams below show
the range of inserts available which can be used with the RC holder. The distance given between the door face and the rear of
the holder when correctly fitted reflect the compressibility ratios of the seal inserts.
Normally RC is fitted to a planted stop. This enables fine adjustment of the seal position to be made relative to
the door face.
It can either be surface mounted or set into a groove. Fixing is by pins.
Before starting to fit the seal
refer to the drawings below to identify the seal insert which you have ordered.
Measure the dimensions of a section (Fig.1)
and check that the actual combined depth of the holder plus the seal insert allows for the compression ratios shown
in the illustrations.
It is vitally important that provision for these sizes is made in the joinery detail.
PREPARATION Of TIMBER
Timber edges which may affect the proper working of the seal must be chamferred or well rounded to avoid damaging the insert.
The groove, into which the holder is pinned, is cut on one edge and must be accurate to the sizes of the aluminium holder (Fig. 1).
FITTING TO PLANTED STOPS
With the planted stops fitted on the head and side frames, at the correct distance from the door, measure the distance at the head
between the side stops. Cut the holder and insert seal to fit and fix the holder in place across the head stop using the supplied pins.
If the holder has been cut to customers measurements there should be a small milled slot, approx. 100mm from one end.
This allows the rubber insert to be installed even though both ends of the holder may be covered when installed in place.
If the aluminium strip is supplied in standard lengths it may be necessary to cut the slots as required. See Fig.1 for details.
Measure each side stop between the head and threshold. Cut the holdr to suit and fix with the pins. The milled slot can be either at
the top or the bottom.
Cut and feed the seal insert into the holder through the slot and push along its complete length.
To prevent movement of the seal insert in use crimp the ends of the holder on to the insert.
Operate the door and adjust if necessary.
FITTING RC TO AN EXISTING STOP
RCV/RCW PINNED INTO A REBATE CUT IN EXISTING INTEGRAL STOP
IMPORTANT REMINDER
To prevent damaging the insert the closing edge of the hinge side of the door should be well rounded as shown. This applies
particularly when fitting RCY, RCX and RCZ.
Solvent base glues, paints etc must not be allowed to come in contact with the elastomeric seal inserts.
