HOW TO INSTALL A SAFE
Ideally the safe needs to be bolted down to a concrete floor. If this is not possible and you have a timber floor then make sure it is bolted through into the timber floor joist.
Make sure there are no water or gas pipes or electrical cables under the floor before drilling the fixing holes. Do not fix in areas where there is underfloor heating.
You need to position the safe in the exact spot and mark the floor through the fixing holes in the safe. Then move the safe out of the way and drill the bolt holes into the floor. Then replace the safe and fit the anchor bolts throught the base of the safe into the floor. Follow the manufacturers instructions and bolt the safe down to the floor with the fixing bolts provided. If fixings for a timber floor are not provided then use timber coach bolts. Fix to the wall as well if possible.
If fixing to the wall as well then make sure the safe is flush against the wall. You may have to remove a section of skirting board to achieve this. If you are unable to bolt to the floor then make sure you bolt the safe to a solid wall.
Please check with your insurance provider to make sure you are covered when installing your own safe.
To ensure their high security attributes, Underfloor Safes require a High Grade Concrete Encasement containing suitable reinforcement.
The installation should be undertaken by a qualified installer whose survey would determine a convenient ground floor site free from any electrical wiring, water or gas pipes, etc., and where the use of attacking tools would be restricted.
If the safe is for insurance requirements your insurance company should be made aware of your intention prior to installation.
WHEN THE INSTALLATION IS COMPLETE NO PORTION OF THE NECK OR DEPOSIT TUBE MUST PROTRUDE ABOVE FLOOR LEVEL.
1. Remove door from safe to a place away from site to avoid any form of contamination.
2. To prevent dust or concrete from entering during installation fill the inside of the safe and neck with crumpled newspaper.
3. For round door models ensure that the A.B.S neck is fully engaged in the steel collar. Where two necks are used see that they are correctly located. Single or double A.B.S necks may be glued to avoid subsequent dislodgement.
4. Apply sealant around neck-to-collar joint. Replace lid
Steel reinforcement must be used. A suitable type is Weldmesh Ref. No.26: 2” x 2” (50 mm x 50mm) x 6 S.W.G. Round door safes require a vertical layer approximately 9” (225mm) diameter by 3” (75mm) high formed to fit around the A.B.S neck. A 30” x 30” (762 mm x 762mm) piece is notched at the corners and the edges are bent downward leaving a horizontal layer approximately 22” x 22” (560 mm x 560mm). A hole is cut into the mesh to accommodate the neck and to allow positioning in the concrete 2” (50mm) below floor level. Additional steel reinforcement may be added to increase concrete protection at sides of safe if required. Reinforcement is arranged similarly for square door safes with both vertical and horizontal layers.
1. Remove any floor covering and expose concrete floor.
2. Mark an area on the floor to allow not less than 6” (150mm) of concrete round the sides of the safe.
3. Cut through the concrete and excavate to a depth of 3” (75mm) more than the total depth of the safe.
4. Angle the sides of the hole outwards by 2” in order that the concrete is dovetailed into the floor.
5. For installation in a wooden floor it will be necessary to confine the concrete to the dimensions given with the use of shuttering.
CONCRETE PREPARATION AND DAMP-PROOFING
Use only good quality sand, aggregate and cement. Recommended Specification: PARTS BY WEIGHT
Coarse Graded Aggregate ¾” MAX 3 Fine Graded Aggregate 3/16” MAX 1 ½ Ordinary Portland Cement 1 Water Not to exceed 24.4 litres for every 50 kgs of Cement
All materials to conform to the appropriate Bristish Standard Specification. A suitable dry mix preparation is Marley Mix 3-1 ½ - 1 B.S 5838 Part 1 DO NOT CONCRETE UNLESS THE AMBIENT TEMPERATURE IS AT LEAST 3ºc MIN.
INSTRUCTIONS FOR INSTALLING UNDERFLOOR SAFES IN CONCRETE AND WOODEN FLOORS & GUARANTEE REGISTRATION
Materials must be frost free and in cold conditions use water heated to 10ºC. Accelerating or other admixtures containing calcium chloride must not be used as these are highly corrosive. The addition of a waterproofing agent, however, may be necessary. Where site excavation reveals extreme damp presence, the hole should be lined with a heavy gauge polythene sheeting.
Thoroughly dry mix all materials and then add a minimum of water to allow the concrete to be compacted. Do not add too much water as this will reduce the strength of the construction. The amount of water shown in the column above produces a 2” (50 mm) slump which should not be exceeded.
1. Cover the base of the hole with 4” (100 mm) of the concrete mix.
2. Lift safe by top plate (avoid dislodging round type neck), place in centre of hole and work down into the concrete bed until the lid is at the correct level with surrounding floor.
3. Use a spirit level to span the hole to check the safe is level.
4. The concrete is added in layers of 4” (100mm): each layer worked well into the previous layer with a tamping tool. A section of timber, or similar, about 39” (1m) long, with a ramming face approximately 1” (25mm) square is ideal for the purpose. Work methodically over entire surface and ensure full compaction of concrete. Take care not to disturb the safe or dislodge the neck through-out installation.
5. The steel reinforcement is introduced into the concrete at the appropriate stage.
6. When the hole is filled with the concrete mix to within ½ “ (12mm) of the surface, take the safe door from bag and after removing lid, insert door into safe to ensure that misalignment has not occurred. ANY NECESSARY ADJUSTMENT WOULD NEED TO BE MADE NOW BEFORE CONCRETE IS SET.
7. Screed last ½“ (12mm) with a mixture of sand and cement to bring to a smooth finish. THE SAFE MUST NOT BE USED FOR 14 DAYS AFTER INSTALLATION.
CARE AND MAINTENANCE
The subsequent application of a lino paint by the owner/user will act as a surface stabiliser and help to control grit. Ensure that any floor washing activity etc. does not result in water entering the safe. Keep safe door and locating collar dry, clean and lightly oiled. Dirt and grit etc. can be damaging to the locking mechanism. To ensure that the safe remains in good working order always close the escutcheon and see that the lid is replaced properly after use. The use of silica gel is recommended where condensation is a problem or where the safe remains locked for any extended period of time.
Wall safes are designed to be cast in place with reinforced concrete. This invloves removing the bricks or blocks out of a section of wall where you want the safe to go and replacing them with the safe surrounded by reinforced concrete. It is advisable to get competent person to install a wall safe.
Wall safes are designed with similar dimensions to standard bricks and blocks so that they easily fit into the space created.
