. A number of systems have multiple backups . The logic of the Liberty Heavy’s control never prohibits the start of a dive even in the event that malfunctions are detected; it only indicates the status if able to do so in light of the damage .
If you do not accept the risk and you are not a trained, careful and disciplined diver, do not dive with the Liberty Heavy . The manufacturer does not bear any responsibility for use of the Liberty Heavy if the apparatus has been modified in any way that is not stated in this manual or in the technical guidelines issued by the manufacturer.
System of documentation Version The technical documentation is subjected to a process of continual development and improvement .Therefore, please regularly check the website at www .CCRLiberty .com updates . Technical guidelines The manufacturer can issue technical guidelines . It is strongly recommended that the user regularly checks www .CCRLiberty .com for new guidelines .
Heavy Liberty Rebreather is a modification of the original Liberty Rebreather . Liberty Heavy retains the complete head of the device including electronics, handsets and all sensors . However, Liberty Heavy requires a different mounting than the classic Liberty . This procedure is included in this manual and assembly checklist .
. The Liberty Heavy configuration has a 20 l wing in the base, but any other rebreather wing (with holes for hose passages) can be used according to the required volume to your chosen size and number of cylinders .

For the 2–3 liter bottle configuration we use the small brackets . If we want to use the so- called GUE configuration with 7 liter bottles, we use large brackets . In both cases, it is still possible to attach a second set of bottles via the additional holes for the attachment straps . Stand for 2×3 litre configuration .

Each configuration comes with just one set of brackets suitable for that configuration . In case of combining different configurations, it is possible to purchase separately brackets for the given configuration .
Assembly The Liberty Heavy frame is designed so that any wing and backplate can be used as long as they have standard bolt hole spacing . Assemble the Liberty Heavy by installing the wing, counterlung assembly and backplate onto the bolts in the frame one at a time .
Fixing the Tanks Attach the tanks to the frame using straps with an buckle . The height of the tanks affects the reach of the low pressure hoses, so choose a height that will allow the hoses to reach the intended position . In particular, the position of the oxygen hose connection to the solenoid is critical Close the strap with the buckle and make sure...

Left post diluent first stage • 580 mm long hose for MAV diluent, which runs along the inspiratory hose to the single hose adapter on the BOV . • Dry suit hose leading directly down from the bottom port . This hose is not supplied with the unit .
. This allows the counterlungs to be positioned one level higher or lower . Adjusting the trim At Divesoft, we have tried to make the unit as balanced as possible . Yet, of course, it cannot be guaranteed that the trim will be tuned for everyone . Fine adjustment of the horizontal balance is achieved by moving the on-board cylinders relative to the unit .
Location of tanks for dry suit The dry suit filling tank can be positioned in two ways: 1 . The standard way on the backplate . In this position, the tank may interfere with proper counterlung filling and thus impair work of breathing . 2 .

Location of additional equipment The positioning of the light canister or heating system can be either classically on the belt, or if you have space left, the battery can be placed in the position of the second set of cylinders . Assembly of the loop and Dive checks USE THE MAIN LIBERTY USER MANUAL FOR THE REST OF THE REBREATHER INSTALLATION.

Maintenance After each dive in salty or polluted water, the device must be washed with clean, fresh water . After each day of diving, disassemble the device . For dismantling, use the reverse assembly procedure . Put caps on the MAV and ADV connectors and disinfect the entire loop, including the counterlungs, and rinse with drinking water .
