Inground Installation Instructions

 

Recommendation

• Installation work has to be carried on according to the enclosed installation manual of Unilamp.

• The water drainage system must be tested to ensure that it is working sufficiently. Water must drain in not more than 30min from the installation niche. Insufficient drainage will result in moisture accumulation within the luminaire housing.

 

➝ Before installation

• Power supply must be cut off before installation of the inground luminaire.

           

 

• Carefully check the dimension of the luminaire and verify suitability of the installation location.

            

 

• The inground luminaire must be installed flush to the installation surface to prevent accumulation of water and being a trip hazard.

            

 

• Use gravel or other suitable porous material, with a depth of 200-300 mm to drain water. If use of gravel is not possible use a drain pipe if suitable diameter of not less than 16mm for efficient water drainage. Verify the drainage efficiency.

           

 

• Water must drain in not more than 30min from the installation niche.

           

• Use additional drainage methods if required based on the installation condition. Consult the Unilamp after sales team for assistance.

 

• Check properly the minimum distance to the lighted surface.

           

 

➝ After installation

• Regularly check lens and keep it clean and free of debris such as dirt, sand, leaves, mulch, etc. to maintain the light output.

           

 

Do:

• Turn the power off before installing or performing any maintenance on the inground luminaire.

           

 

• Any damaged safety glass cover must be replaced only with the original spare part.

           

 

• Check the luminaires once a year for accumulated dirt or debris. Clean when necessary in order to maintain the light output.

           

• Only use solvent-free cleaning solutions on the inground luminaire. Consult the Unilamp after sales team for assistance.

 

• Install a surge protection device to suppress high voltage transients and prevent damage to the electronic control gear.

           

 

Do not:

• Installation should not be done under high humidity environment e.g. rainy day or after the rain, foggy weather.

           

 

• Do not let the exposed part of the inground luminaire be covered by the soil, dried weeds or foliage.

           

 

• Do not throw or drop any hard objects onto the top of fittings.

           

 

• Do not use chemical compounds and aggressive agents such as weed repellents fertilizers, acid solvents, and contaminated irrigation water near the inground luminaire.

           

 

• Do not use a high pressure washer to clean the luminaire.

           

 

• Do not use cable protection tape or apply silicon on the connection point. Only use connection accessory recommend from Unilamp. Unilamp recommends to use IP68 quick connectors or gel filled junction boxes.
