1. Make sure that the permeate water can flow freely and that there is no backpressure Backpressure can cause damage to the membrane CAUTION The plumbing in the permeate line can contaminate the high quality water produced by the system ensure that the components are compatible with the application The pH of the reverse osmosis permeate will normally be 1 2 points lower than the feed water pH A pH of 6 5 or lower can be very aggressive to some plumbing materials such as copper piping 5 Locate the concentrate waste tubing Locate the concentrate outlet on the drain side of the concentrate control valve 6 Attach the drain line to the concentrate tubing 7 Run the concentrate line to the drain Water must be allowed to run freely without any restrictions or blockage in the drain line Make sure that no backpressure exists on the concentrate line 8 Ensure that the electrical power requirements of the Spot Zero system match your electrical power supply 9 Spot Zero systems are typically controlled with a liquid level switch in a storage tank The liquid level switch turns the system on when the water level in the tank drops and off when the tank is full If your reverse osmosis system is equipped with an electrical control box the level control is connected to the level control connections in the control box Do not exceed the level control s power rating Liquid level switches can be obtained by your local dealer or dist2.
