Installation Guidelines

Note:  The following information is provided to give guidance only. As all installations are not identical, please contact your GATIC representative for additional information, if required.

 
GENERAL INSTALLATION GUIDELINES
 
Correct installation is essential for a GATIC unit to operate satisfactorily and give a long service life for which it has been designed.
 
Incorrect methods of installation may cause:
 
• Movement or rocking under load;
• Excessive wear and reduced life;
• Damage and/or failure under load;
• Poor sealing between cover and frame seatings.
 
Square and Rectangular Cover Installation note: 

To prevent covers lifting, it is recommended to position covers such that traffic flow direction is from undercut to drawcut.

 

 
 
 
 
 
 
 
 
 
General Requirements
 
General guidelines for installation are provided to give guidance only. As all installations are not identical, please contact your GATIC representative for additional information, if required. Refer to the product catalogue for additional installation detail.
 
Forming of Pit or Slab Openings
 
The guidelines for installation outlined are for installing GATIC units in rebates formed in pit or floor slab openings.
 
As an alternative, units can be supplied with frames bolted to covers for installation directly into pit or floor openings during the actual forming of the pit or floor opening (contact your nearest Gatic office for details).
 
Cover to Frame Matching
 
Gatic covers and frames are mated individually during the machine process and are, therefore, not always interchangeable. A cover from one frame will not necessarily fit another frame. Covers in multiple units are marked and designated individually to particular locations in the frame.
 
Cover Orientation
 
The direction in which a cover can be slid out of its frames is indicated by the position of the cover edge with two or four keyholes. If a wall or other obstacle abuts the opening, ensure that the cover is installed so that the direction of removal is parallel to or away from the obstacle.
 
Concrete Infill and Curing
 
With the exception of solid top covers, all covers and frames must be filled with structural grade concrete (refer to AS3996 for additional information) This is essential if the full strength potential of these covers is to be realized. Concrete infill must be poured and allowed to cure with covers installed in frames.
 
Careful Handling Essential
 
Frames may suffer twisting and damage to joints if subjected to shocks or heavy blows.
 
Cover to Frame Sealing
 
The application of GATIC MANHOLE SEALING COMPOUND is recommended for all cover to frame seatings. Lubricating greases are not recommended as they melt, dry out and cause deterioration of seating surfaces.
