4. Once the lamp is fully seated on the connector, slide the
connector over the aluminum retaining nut. Make sure
the metal retaining ring on the connector is pulled away
from the body of the connector in order that the connector
may slide fully over the retaining nut. Once the connector is
located fully over the retaining nut, slide the metal ring back in
to lock the connector in place (Figure 2E). As this connector is
keyed to the reactor chamber, make sure the notch on the
connector (Figure 2D) is located over the ground lug located
on the reactor chamber.
Quartz Sleeve Replacement / Cleaning:
Mineral deposits and sediment may accumulate on
the quartz sleeve decreasing the UV energy detected.
Good maintenance of filtration equipment will reduce
the accumulation of residues. If necessary, remove the
quartz sleeve and clean with a commercially available
scale remover (CLR, Lime-Away, etc.) and a lint free
cloth. Repeat the process as often as necessary to keep the quartz
sleeve clean. Be sure to remove all traces of cleaning fluid from the
sleeve before it is reinstalled in the reactor (be sure not to allow
liquid inside the sleeve).
1. First remove the UV lamps by following steps 1 & 2 as outlined
in the “Lamp Replacement” section on page 7.
2. Shut off the upstream water supply that feeds water into the
reactor chamber.
3. Shut off the downstream water supply. If your system does not
have a separate downstream valve, simply open a downstream
faucet to release any pressure that may be built-up in the
system.
4. Remove the aluminum retaining nut by turning counter
clockwise (Figure 3A). To drain reactor, remove drain plug
(see page 1) and drain into a bucket. Grasp the quartz sleeve and
fully remove from the reactor chamber. As with the lamp, make
sure the sleeve is removed from the reactor chamber being careful
not to angle the sleeve as it is removed from the reactor
(Figure 3B) to avoid breakage.
5. Clean the sleeve as outlined above, or replace with a new
sleeve. Reinstall the quartz sleeve in the reverse order. The
Cobalt reactor is designed for easy installation of the quartz
sleeve by incorporating a unique sleeve centering guide. To
install the sleeve, carefully insert the sleeve into the reactor
chamber (do not drop) and push the sleeve until it firmly seats
in the end of the reactor centered in the sleeve centring guides
(Figure 3C). Install a lubricated (silicone release grease) o-ring
(Part number OR-212) onto the sleeve until it is positioned
against the chamfered seat (Figure 3D).
6. Reinstall the aluminum retaining nut on the reactor chamber
and tighten by turning clockwise. The retaining nut should
be hand-tightened only, the use of a wrench is not required, or
recommended. Reinstall the UV lamp and Safety-Loc™ connector
as outlined in step four of the “Lamp Replacement” section.
7. Slowly turn on water and pressurize the reactor to verify that
there are no leaks.
8. Reconnect to power source and follow the Controller start-up
sequence to make sure the system is operating properly.
