Introduction

Use of this manual

This is the Liberty Heavy rebreather manual.The manual only deals with the specifics of the

Heavy version of Liberty and is only a manual supplementing the basic functions and controls

described in the Liberty main manual. Operation of bailout rebreather mode features is

described in the stand-alone Bailout standby mode manual.

To understand the full functionality of the device, read the CCR Liberty main manual.

The Liberty Heavy is intended for use exclusively by a trained person who is capable of fully

understanding the instructions contained in this manual or is in the process of training with

the Liberty Heavy in a course accredited by the manufacturer..

Responsibility of the Liberty Heavy user

Strong emphasis was placed on reliability during the development of the CCR Liberty Heavy.

Individual internal parts are separated in order to minimize the impact that failure of a given

part may have on the rebreather’s basic functionality. 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. When cave diving, the inability to submerge can mean not being able to return from

a dive; therefore, the Liberty Heavy does not impede submersion.

The user must always decide responsibly whether he/she switches to a backup apparatus or

even starts a dive with a partially malfunctioning rebreather.

A Liberty Heavy user must accept the fact that diving involves risk. Following everything that

the user has learned in the Liberty Heavy’s technical documentation and in training on diving

with this rebreather can reduce the risk but cannot eliminate it. Safety when diving is further

improved by regular training, methodical education and following good diving practices. Diving

with a rebreather requires a far higher degree of carefulness and discipline than diving with an

open-circuit apparatus.

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.

Notice

The Liberty Heavy is not a buoyancy compensator, nor a harness for attaching the device to

the diver’s body.

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 for

updates.

Technical guidelines

The manufacturer can issue technical guidelines. It is strongly recommended that the user

regularly checks www.CCRLiberty.com for new guidelines. Registered users will receive

notifications by e-mail.

Update of printed documentation

The electronic and printed forms of the manual may not be completely identical. In case of

insignificant changes (correction of minor typing errors, for example), only the electronic

version is updated.

User support

Registered users are entitled to technical support. The extent of free support can be limited.

The technical support department at Liberty systems s.r.o. will provide limited support for

potential and unregistered users.Prior to submitting a question, please familiarize yourself

with the general principles of rebreather diving with trimix and the freely available CCR Liberty

technical documentation.

Use

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.

Description

Liberty Heavy can be used in a number of different configurations consisting of mutually

compatible parts.The device’s own configuration can be created in the online configurator

https://ccrliberty.com/configurator.

Liberty Heavy brings a new configuration of the popular rebreather with completely redundant

electronics. Divers can clamp the Liberty to their own standard backplate, bringing a high

level of comfort, versatility, and a wide range of height adjustment options for any diver’s body

height. This gives the diver ample headroom that does not restrict anything. The adjustability

of the device’s seating on the back brings the possibilities of fine-tuning the perfect trim.

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.

The Liberty Heavy allows you to change the configuration of the on-board cylinders from the

classic 2–3 liter to the large 7 liter cylinders in DIR configuration. Up to 4 cylinders can be

mounted in various combinations.

The removable wire stand allows very practical and convenient mounting of the off-board

bottles while guaranteeing high stability of the device on land or on the boat.

The stainless steel frame of the instrument is well adapted for easy and elegant hose routing.

The Liberty Heavy is thus an excellent choice for all divers looking for a very comfortable,

compact and stable unit with a wide range of customization options, for divers looking for

a unit for the most demanding dives with many bailout cylinders, but also for recreational

divers at the beginning of their rebreather career.

All the extremely advanced features of the CCR Liberty remain. The configuration uses the

original back-mounted counterlungs and manual valve system right at the mouthpiece. The

work of breathing thus remains unchanged from the highest standard Liberty rebreathers.

Conversion

Liberty Heavy is compatible with the standard CCR Liberty , so it’s possible to convert CCR

Liberty to Liberty Heavy using a conversion kit.

The head including the handset and the buddy display, canister and scrubber are used from the

back-mounted device.Alternatively, it is possible to replace the scrubber with a canister for

a shortened version.This version is not a standard part of the conversion kit, and needs to be

requested separately.

By purchasing the conversion kit to the back unit, Liberty Heavy can be rebuilt to classic CCR

Liberty.
