 WARNING

Before closing the cover, check that

the gasket is positioned correctly in its

seat. Make sure it is perfectly clean, and

lubricate it with a thin ﬁlm of silicone

grease.

NOTE

When applying the silicone grease, be

careful not to get the battery or contact

plates dirty.

NOTE

Nemo Air may show a low battery charge

after the battery has been replaced. If this

happens, run a battery check by entering

SYSTEM mode.

NOTE

Do not discard the old battery in the

environment. Mares adopts a policy of

respect for the environment, and urges

use of the appropriate separated waste

collection service.

 WARNING

Do not replace the battery within the

3 minutes immediately following a dive.

Replacing the battery too soon after the

dive will result in loss of the data for that

dive. In any case, remember that replacing

the battery causes the residual nitrogen,

desaturation time and no-ﬂy time data to

be lost. It is therefore advisable to make a

note of this information before replacing

the battery.

 WARNING

Do not replace the battery between

repetitive dives.

INSTRUCTIONS FOR CONNECTING NEMO AIR

TO THE HP HOSE

Nemo Air is made up of two distinct elements:

the computer and the high-pressure hose,

which are connected to each other by means

of a quick-release coupling designed and

tested for an operating pressure of 300 bar.

The hose must be connected to the regulator’s

ﬁrst stage before the latter is mounted on the

tank: if this operation is carried out when the

regulator is already assembled on the tank,

make sure that the tank valve is fully closed

and that the entire system is depressurized

by pressing the purge button on the regulator

second stage.

 WARNING

Under no circumstances replace the

hose ﬁtted on the computer with one of

a different type; consult your dealer or

Mares for information about the type of

hose to be used.

 WARNING

Before pressurizing the instrument, check

that the quick coupling has been correctly

engaged.

 WARNING

The Nemo Air can only be connected

and subsequently disconnected from the

high-pressure hose after depressurizing

the group. Therefore, if the computer

is assembled on the ﬁrst stage of a

regulator that is already connected to a

tank, depressurize the group as described

above.

In order to connect the computer to the hose,

insert the connector attached to the hose into

the connector attached to the computer, and

then press all the way in (ﬁgure 55 and 56):

FIG. 55

FIG. 56

Do not use tools to tighten the Nemo Air

connection.

 WARNING

Attempting to carry out operations in the

presence of high pressure may result in

serious injury.

Connect the threaded 7/16” UNF

terminal to a high-pressure outlet on the

regulator’s ﬁrst stage (check the regulator

instruction manual to ﬁnd out which are

the high pressure outlets) and tighten

(max 4-5 N.m. / 35.4-44.3 lb.in) with a

hexagon wrench (14 mm).

INSTRUCTIONS FOR ATTACHING

THE COMPASS

(OPTIONAL COMPONENT, SOLD SEPARATELY)

With reference to ﬁgure 57, the following steps

are necessary in order to attach the compass:

1. Unscrew the 6 screws that fasten the two

shells of Nemo Air.

2. Remove the bottom shell.

3. Remove the top shell.

4. Remove the top cover.

5. Fit the compass module.

6. Replace the bottom and top shells and lock
