Method Of Statement for Testing & Commissioning Of Water Filtration System

The water filtration system is used to filter the suspended particles in the water and mostly in the residential and commercial building these are installed in the mechanical floor for the purpose of turbidity, odor and smell removal. Typically the water filtration system consists of a booster pump, filtration tanks and filtration media.

Installations are done as per manufacturer recommendations with all necessary piping and accessories to be completed as per approved layout drawings etc. Before testing & commissioning of water filtration system following pre commissioning checks to be done.

  • Approved brand and reference no. to be checked
  • Alignment and level of equipment to be checked.
  • Accessibility for maintenance to be checked.
  • Flexible, valves and check valves to be checked.
  • Electrical panel, wiring, conduits IP rating to be checked.

Testing & Commissioning Of Water Filtration Systems

Step 1: The location of your multimedia filter is important. It should be in a protected dry, level and non-freezing area (34-120 degrees F).

Step 2: You will need a drain for the back-washing cycles. If possible, the drain should be no farther than 20 feet from the filter. The drain line will be under pressure when the backwash cycle is working, therefore make sure the drain line is secured.

Step 3: Make sure the main water supply is off. With the water supply off, place the bypass valve into the service position. Open the water supply valve very slowly to approximately the 1/4 open position. In this position, you should hear air escaping slowly from the drain line. CAUTION: If opened too rapidly or too far, some multimedia filter media may be lost and plugging of the valve is possible.

Step 4: Check for leaks and tighten any loose fittings if any leakage is observed.

Step 5: When water begins to flow steadily from the drain, signifying the air has been purged from the tank, open the main water supply valve all the way. You will notice that the water running in the drain line is slightly cloudy. This is normal, and you are now backwashing a small amount of “fine” material contained in the multi-media filter media from the bed. After the water in the drain line is running clear to the drain (this can sometimes take up to ½ hour), initiate a manual backwash and allow the unit to run through a complete cycle.

Step 6: Now refer to the manual that was supplied with you specific model and set the time and backwash cycle frequency as directed. We recommend that you set the multi-media filter to backwash one to two times each week.

Testing The Micro Switch Function

The V3017 can be used as an auxiliary switch that sends a signal to enable or disable operation of a secondary piece of equipment when the WS2 valve starts a regeneration cycle and sends another signal when the WS2 valve returns to service.

Remove the switch actuator on the drive bracket. Install the washer on the piston rod in the correct orientation.

Nip off the shorter actuator to allow room to make wire connections to the microswitch. Orientate the actuator so the word SERV is pointed toward the valve and up so the longer actuator is in contact with the piston rod. Attach the microswitch/ actuator combination to the drive bracket using the screws. Do not over-tighten screws.

Because the V3303 terminals are unshielded, make sure the connection is made using the plastic V3302 connector.

Connection to the supplied switch may be made using the V3303 terminals. Use installer supplied wire to connect the secondary piece of equipment. The wire connects to the microswitch using the V3303 terminals.
