Method to be Employed

Material Handling & Storage

On receipt of pipes and fittings, the materials shall be handled and stored in line with the following procedure:

All materials delivered to the site shall be new, free from defects, and of the same type & model as per approved material submittal.

The materials should be received factory packed and should remain so until installation.

Delivered materials shall be carefully off-loaded using necessary manpower, or lifting equipment as
necessary to ensure no damage occurs. All lifting & handling procedures will conform to the manufacturer’s recommendations.

Upon completion of receiving inspection, the Electric Water Heater units will be segregated model/size-wise and stored accordingly for easy identification.

Materials to be stored on a flat surface in well ventilated, dry, and covered storage area.

Electric water heaters and their accessories shall be transported to the site in their original packaging.
Sufficient manpower & appropriate lifting equipment shall be used to load and transport the materials to the site/installation area.

Electric water heaters shall be fully protected/covered at all times.

Preparations/Pre-installation checks

Ensure that the Method Statement for Water Heater Installation is approved and the material delivered is inspected & approved by the consultant representative.

Confirm all approvals such as layout/detailed shop drawings, MEP coordination drawings, material submittals are available.

Ensure the materials/accessories that are available which are received from the store are free from damages during transportation.

Check & coordinate with other trades/services prior to the installation. Ensure all civil works are completed for the area of installation plastering, painting, etc.

Ensure that the exact location of EWH is coordinated with the electrical layout to have access to the power supply layout.

Installation-Method Statement for Water Heater

Installation of Electric Water Heaters

Follow the manufacturer’s procedure on how to install the electric water heaters.

Select the installation as per the approved shop drawing and coordination drawing.

Confirm the correct model no., size & capacity of the electric water heaters & mark the final location for installation.

Make sure EWH is mounted on the wall surface. Mark and drill correct holes for the bolts.

If it is not possible to directly install the EWH on the wall surface, use additional steel supports as required such as C- channels, angle bars, etc. Mark and drill correct holes for the bolts of the frame on the walls.

Use appropriate drilling machine to drill for required diameter/size of screws insertion on the wall with a correct drill bit and ensure that all fasteners are properly tightened, supports are aligned & secured.

Raise and install the EWH gently into the wall bracket/structure supports.

Ensure the EWH is properly installed, all screws are fastened and supports are rigid.

Piping Connections to Electric Water Heaters

Install the cold water supply inlet & hot water supply outlet piping by removing the temporary caps from the inlet & outlet connection nipples. Re-check to ensure that all pipes, valves, fittings & accessories are properly connected and the direction of water flow is correct.

Install valves and other accessories as per the latest shop drawing. All valves to be installed should be located for easy access to closing maintenance purposes.

Install the temperature & pressure relief-safety device valve as per the manufacturer’s recommendation.

Provide proper pipe supports and pipe hangers to the associated piping, ensure pipe supports, and hangers are secured.

Provide proper identifications, tagging & labeling of pipes for flow direction of the water.

Provide access doors for EWH where ever necessary/applicable for maintenance purposes.

A thermostatic mixing valve will be installed for the regulation of the hot water supply to the building.

Approved standard detail will be followed for the installation of the thermostatic mixing valve.
