Danger to life from incorrect handling and transport!

Incorrect handling and unsuitable transport of window elements can result in dangerous circumstances and cause severe accidents, even including death. Therefore:

  • During loading and unloading, select force application points which exclusively create reaction forces appropriate to the designed layout of the hardware components for the intended installation location.
  • During handling and transport, ensure that hardware is in the locked position, so as to prevent an uncontrolled opening of the window. During transport, additionally use suitable means of securing, e.g. tensioning belts.
  • Use only transport protections designed for the respective clearance.
  • Wherever possible, undertake transport in the intended installation position – transport windows upright and glazed.
  • Prevent diagonal moving and slipping of the sash with respect to the frame (e.g. by using spacers).
  • If transport in the intended installation position is not possible, unhinge the sash, and transport it separately from the frame to which it belongs.


Operating & Safety Instruction

Handle Installation

The Handle is installed on the window sash and it has to be in the turn-mode. To dismantle an old one, apply the instructions in the reverse order.

You must maintain the finish to provide continued protection of the wood. Not maintaining the exterior and interior finishes can cause permanent damage to the product. Lack of proper maintenance can cause product performance to deteriorate. An inspection every six months on painted surfaces is necessary and every 90 days on stain finish surfaces. Do not power-wash the windows and doors. We recommend using the “Wood stain and paint cleaner and conditioner” to remove all the dirt on top of the finish coat and remoisture the coat and it will provide more durable to the wood protective coat.


  • Casement and awning operator hinges and locks should be lubricated every year. Use white Lithium grease on the hardware gears and silicone spray on hinge tracks and locks. Be sure to clean the areas needing lubricant prior to applying the lubricant.
  • Sliding and lift & slide door hardware should be lubricated on a yearly basis. This includes the lock mechanism and door roller wheels and track. Use silicone spray. Clean track before applying lubricate.

Exterior, Joint Maintenance & Weather-stripping

  • Be sure to inspect all exterior wood joints every 6 months. This includes the stucco/brick mold joint, frame joint or frame sill nose joint. If any joint is not sealed, repair and refinish the parts involved.
  • Be sure to inspect all exterior clad finish every year. This includes the stucco/brick mold joint and complete frame. If any rust or unfinished part is exposed to the elements, then sealed, repair and refinish the parts involved or replace it if it is corroded.
  • Be sure to inspect all hinges every year. This includes the search for rust or any sign of corrosion. If any rust/corrosion is found, replace the part immediately with an equivalent approved hinge.
  • Check weather-stripping on a 2 year schedule. Replace as needed. The weather-stripping is an important part of the product. It helps keep water and air from penetrating to the interior of the home.

Coastal Clad Additional Unit Maintenance Requirement

In order to maintain the appearance and extend the finish life on clads units, it is necessary to proceed to a normal and regular maintenance (including hardware). It is required to maintain the Warranty. Windows and doors which are located near to a salt concentration water (20 miles) have to follow a systematic fresh water cleaning program so as to prevent the accumulation of concentrated salt deposits.
