SAFETY INFORMATION
Electrical Safety
• Only connect the power cord to a 120V properly grounded outlet.
• Never pull the power plug from the outlet with a wet hand or allow the plug to get wet.
• Keep the power cord out of heavy traffic areas.
• To avoid a fire hazard, never put the power cord under rugs, near radiators, stoves or heaters.
• Do not use a damaged power cord or plug. If the power cord is damaged, a qualified service technician must replace it.
• Do not use an extension cord with the PURA Ultimate.
Installation and Usage Safety
• Keep the PURA Ultimate away from direct sunlight and excessive humidity.
• Keep at least four (4) inches from the wall.
• Don’t lay the PURA Ultimate down on its side. If for some reason the unit was placed on its side, it must stand
upright for a minimum of two (2) hours before operation to allow the compressor to stabilize.
• Connect the water supply to a cold water line only. Feedwater over 105°F (40°C) can damage the treatment
components.
• Never install the system where it could freeze.
• If the feedwater pressure is over the recommended operating pressure of 60 psi (4 bar), install a pressure-reducing
valve in the water line. Be aware of pressure surges or water hammer.
• Filters should be replaced on schedule. Overused filters will deteriorate the performance of the system.
• Drain the water out of the PURA Ultimate after long periods of non-use, such as over the long weekend; this will
allow a fresh batch of water to fill the system.
