INSTALLING THE PURA ULTIMATE
Position the Unit
1. Locate the unit as close to the water supply and the electrical connections as possible.
2. Level the machine using the adjustable feet.
3. Remove the top cover and the lower front panel to access the filters.
4. Check that the filters (optional) and RO cartridge (optional) are all securely installed after transporting to the
installation site.
Establish the Water connection
1. Flush the water supply pipe until it runs clear before making the water connection to rear of the unit.
2. Connect the unit to the water and plug in to a power supply.
3. Slowly turn on the water supply.
4. Check that the water treatment system begins to fill the reservoir. Check all connections for leaks.
5. Once the reservoir fills, depress and hold the Hot unlock button (left-most button) followed by the Hot dispense
button (right-most button) and verify that water dispenses from the faucet.
6. Depress and hold the Cold dispense button until water dispenses from the faucet.
7. Depress and hold the Room dispense button until water begins to flow
8. Turn ON the Red Power Switch to start the chilling and heating processes.
9. Verify that the compressor and heater are both working. This is best accomplished by placing a hand on top
of the compressor to feel for vibration, and by dispensing water from the hot tank (after 5 minutes) noting a
temperature increase in the water.
NOTE If the filters have remained in the unit for more than 24 hours since they were flushed and
transported to a customer location, it is highly recommended that they get flushed to the drain
before installing.
Install a pressure regulator, if needed, on the incoming water supply line, set to 40-60 psi.
The unit should not be exposed to direct sunlight, heat sources, or an ambient air temperature
above 90°F (32°c) or below 37°F (3°c).
Make sure there is adequate clearance around the unit to allow for heat dissipation of the
condenser. The warmer the environment is surrounding the unit, the more clearance that is
required. A typical office install should require 2 inches of clearance all around the machine.
Installs in factories, warehouses, and garages, where the ambient temperature is above 80°F, will
require a minimum of 4 inches clearance.
cAUTION! The unit is now live. Take suitable safety precautions.
NOTE do Not turn on Red Power Switch yet.
NOTE Because it will take three to five (3-5) hours for the RO system to fill the reservoir, take along
a few jugs of freshly prepared RO water from your shop to fill the reservoir for the first time.
