Cartridge Replacement
(See Figure 3, page 9)
The frequency with which you will need to replace car-
tridges is dependent on your feedwater’s characteristics
and your purity requirements. Replace the cartridges
when the product water purity drops below acceptable
levels of resistivity or when organic levels become too
high.
Cartridge Removal
1.
Disconnect the unit from the power supply.
2.
Open the cartridge access door in the rear of the
unit by sliding the latch down and pulling the door
toward you. The door will swing down.
3.
Grasp one of the cartridges at the bottom and pull it
straight up to disconnect the lower end cap from
the lower socket.
4
Move cartridge upward until upper socket is in key-
hole of keyway. (See Figure 3.)
5.
Pull cartridge straight out from unit to disconnect
upper end cap from upper socket.
6.
Repeat steps 3 - 5 with the other cartridge.
7.
Discard the used cartridges. (See note below.)
8.
Install new cartridges and rinse according to the in-
structions for Cartridge Installation in the Initial
Operation section (page 8).
0.2 Micron Filter Replacement
Replace the 0.2 micron filter whenever any of the follow-
ing conditions occur: every 30 days, the product water
flow rate is reduced or bacteria break through. The 0.2
micron filter is shipped assembled with a bell. To replace
the 0.2 micron filter assembly:
1.
Remove the old 0.2 micron filter assembly by turn-
ing it counter-clockwise until it is free from the Luer
fitting.
WARNING
Disconnect from the power supply prior to main-
tenance and servicing.
Disassembly of water lines and removal of car-
tridges will result in water spillage. Do not per-
form these operations where spilled water could
contact equipment that requires electrical service.
Electrical shock hazard could result.
Refer servicing to qualified personnel.
NOTE
The cartridges will still contain water when re-
moved. Therefore, you will want to have a sink,
bucket or other waterproof container available to
place them in after removal.
NOTE
A small amount of water will drain from the car-
tridge when it is disconnected from the lower
socket. Plug the cartridge’s lower opening with
your finger to minimize water spillage while you
finish removing the cartridge.
NOTE
Used cartridges may be recycled. See P.U.R.E. in-
formation packed with new cartridges.
