3- Do not install on water that is microbiologically unsafe without adequate disinfection before or after the unit. Foreffective disinfection install a Rainfresh Drinking Water System or Rainfresh UV disinfection system.- For use on cold water only.- Only use thread seal tape (Teflon® tape) for fitting connections into unit. DO NOT USE pipe dope or chemicalsealants.- If water pipes are used to ground electrical system, install jumper wire (#4 gauge solid copper wire) across the unitto maintain proper grounding of your electrical system- Protect your unit from freezing - drain the unit if freezing temperatures exist.- NOTE: IF SOLDER TYPE FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections. All solder jointsshould be made before joining pipe to filter head. Use only lead-free solder and flux.- DO NOT over-tighten metal fittings on to unit connections.- You will need softener salt with this unit (not included). Softener salt is sold at most retailers.- Place the unit on a flat level surface. Do not place shims under the unit to level it. The weight of the unit full ofwater and salt can cause the softener tank to crack at the shim.- The unit should only be moved by 2 or more people due to heavy weight. Failure to do so can result in back or otherinjury.- The unit must be installed in an area where there is reasonable access to the salt tank for regular salt filling.INSTALLATIONElectrical Requirements: The automatic control valve requires a constant power supply - 110V AC. We recommend a GFI (ground faultinterrupter) outlet within 5 feet of the softener. Extension cords are not recommended. If water pipes are used to ground electrical system, you will need to install a jumper wire across the filter unit.Unpacking the unitThe unit includes:Unpack the unit and place it at the location where you intend to install it. Stand back and look at the softener to make sure it is standing straight up and nottilted to one side. Make sure your chosen location will be fairly level, dry, andprotected from possible freezing conditions. The softener can sit directly on the floorand will not corrode. DO NOT set the softener onto make shift platforms as this candamage the salt tank, or may cause it to topple. The system has 3 connections - an inlet, an outlet, and a drain line connection. If youare looking at the back of the unit (fig 1), the inlet is on the left side. Warning: Makesure that you have correctly identified the inlet of the system.
