Page 7: Rigging
installation Rigging The WaterGard unit should be lifted and moved by a forklift. If the WaterGard unit is lifted by a crane it should be lifted from the bottom using a platform. The unit should be secure to the platform using the anchor locations. A test lift should be done in order to determine the weight centerline. -
Page 8: Electrical Requirements
installation Electrical Requirements WaterGard’s provided cord serves as the ground. Conduit and water Warning pipes are NOT an acceptable ground. • All wiring must be properly sized, rated, and connected in accordance with local, state, and national electrical codes. The system is pre-wired and tested at the factory. -
Page 9: Startup And Operation
operation Startup and Operation WaterGard membranes cannot be used immediately, they must Note be filled with feed water and allowed to soak for a minimum of 30 minutes, see step 10. 1. Connect the carbon filter (if present) to your potable water supply. The carbon filter will need to be flushed for 30 minutes before being piped into WaterGard. - Page 10 operation 12. Once the pump has started, membrane inlet (pump) pressure should never exceed 135 psi. Use the valve on the discharge side of the pump to adjust the pressure to 105 psi. If pressures over 135 psi are observed it could be an indication of membrane fouling.

Exit and save the calibration. 6. The same procedure applies to the Feed Probe calibration. The probe calibration must be performed using solutions with con- Note ductivity of less than 900 ppm or μS. The conductivity calibration circuit will behave erratically if you attempt to calibrate using a higher value.

maintenance of all setpoints, check the display and the status of all lights and indicators. The more information available when you contact us, the easier it will be to determine the source of the problem. Servicing If any component of the water treatment system is changed or re- Note placed, the user should conduct appropriate tests to ensure that the revised system meets all standards to which it was initially tested. - Page 24 maintenance Typical Service Intervals Task Frequency Estimated Replacement Time Yearly or as quality degrades to be more than 35% of Membrane replacement 15 minutes per membrane incoming conductivity, which- ever comes first.
