The Cobalt is supplied with a lightweight, small diameter
high pressure hose that is both flexible and highly durable
(maximum 5000 psi (344 Bar) working pressure). The
smooth outer covering is UV resistant and will not abrade
or collect sand or debris. The quick disconnect feature
allows you to easily disconnect the Cobalt from the high
pressure hose and regulator system for separate transport
or storage.
Important Note: Always turn the air pressure off
and depressurize your regulator before attempting to
remove or connect the Cobalt to the high pressure
quick disconnect. It will be very difficult to connect or
disconnect if there is pressure in the hose.
Initial set up
Note: We recommend initial set up and check be done
by an authorized Atomic Aquatics dealer.
1. To assemble the hose to your regulator, first identify
the High Pressure port on your first stage you wish
to use (marked HP). Remove the plug, and install the
threaded end (7/16-20 thread) of the hose. Screw in
the hose fitting hand tight, then snug it securely with
a wrench (9/16"). Do not over tighten or you may
damage the threads (maximum 40 inch/pounds).
2. Connect the Cobalt to the quick disconnect fitting.
Unscrew the large plastic locking ring towards the
hose so the end is flush with the end of the metal
quick disconnect fitting ( Fig. 1). Push the quick
disconnect onto the Cobalt and twist 1/4 turn
clockwise to lock it in place (Fig. 2). Gently screw the
plastic locking ring up against the base of the Cobalt
to keep it in place (Fig. 3).
3. Connect the regulator to your tank and slowly turn the
air on. Check for leaks by listening and submerging
the hose fittings in water.
4. Press the Select button to wake the Cobalt and go to
the dive screen to check the air pressure. Upon initial
pressurization it will take approximately 20 seconds
for the air pressure to display.
5. To remove the Cobalt from the quick disconnect,
depressurize the regulator, unscrew the locking
ring, push in and turn the disconnect 1/4 turn
counterclockwise to release. Replace the rubber
protective cap on the high pressure inlet of the Cobalt
when not in use.
