Hardware
The AD500 requires suitable latching in order for the frame seals to fully seal the gap between door leaf and frame. Mechanical latching hardware is essential for the performance of this door, push/pull hardware is not an option.
Extended backset locks (70mm or more) should be used if at all possible. There is a high probability of interference between hardware and frame stop on the push side if standard backset locks are used. Proposed hardware must be advised to Pacific Door Systems Ltd to assess the suitability, before manufacture.
Due to the weight of this door we recommend using the ASSA ABLOY DC700 G-CM heavy duty closer.
Due to the high acoustic nature of this door set, a door closer will pull the door into the closed position, however the door may require additional manual force for latching and full acoustic performance. Installation into small rooms with poor air flow can make the door difficult to open and close.
If a power transfer device is fitted to the door, the door leaf will not be able to open past 110 degrees.
Concealed hinges are not an option on this doorset. The doorset is only available with a full height Pemko _FS_ Full Surface Aluminium Hinge.
Any penetrations through the leaf should be packed with acoustic materials (e.g. batts) wherever possible.
Recommended latching points are shown in the below diagram. Pair doorsets require a designated inactive leaf which is secured top and bottom.
Seals
Frame seals
The perimeter frame seals are self-adhesive seals mounted in the frame rebate, so are hidden when the door is closed. Frame seals should be undamaged and continuous along all sides of the frame.
Bottom seals
There are two options for the bottom seals:
Threshold Plate + Drop Seal | Double Drop Seal |
| A steel threshold plate with a 20 mm step to hold one line of self-adhesive foam seal (identical to perimeter seals) is fitted to the floor. In addition to this there is one drop seal rebated into the bottom edge of the door. The height of the gap between the finished floor level and the bottom of the door must be set up carefully during installation of the door set so that the door will engage with the threshold seal as intended. For optimum performance the threshold plate should be sealed to the floor. | Two drop seals are fitted to the door leaf; one rebated into the bottom edge and one face mounted along the bottom of the blank face. The seals need to engage on a flat, hard surface e.g. a smooth concrete floor or a flat steel threshold plate as shown in drawing below. If a threshold plate is used it should be sealed to the floor. |

Drop seals are supplied fully retracted so as to minimise the chance of damage during transport and installation. After the doorset has been installed, the drop seal should have its throw adjusted to ensure the seal engages fully on the floor along its full width. The drop seal rubber should be long enough to touch the jambs on both sides. This means the seal will project beyond the edge of the leaf.
