1 Safety and user notes

1.1 General safety notes

Carefully read the operating manual before com-

missioning the units for the first time. It contains

useful tips and notes such as hazard warnings to

prevent personal injury and material damage.

Failure to follow the directions in this manual not

only presents a danger to people, the environment

and the system itself, but will void any claims for

liability.

Keep this operating manual and the refrigerant

data sheet near to the units.

1.2 Identification of notes

This section provides an overview of all important

safety aspects for proper protection of people and

safe and fault-free operation.The instructions and

safety notes contained within this manual must be

observed in order to prevent accidents, personal

injury and material damage.

Notes attached directly to the units must be

observed in their entirety and be kept in a fully

legible condition.

Safety notes in this manual are indicated by sym-

bols. Safety notes are introduced with signal words

which help to highlight the magnitude of the danger

in question.

DANGER!

Contact with live parts poses an immediate

danger of death due to electric shock. Damage

to the insulation or individual components may

pose a danger of death.

DANGER!

This combination of symbol and signal word

warns of a situation in which there is immediate

danger, which if not avoided may be fatal or

cause serious injury.

WARNING!

This combination of symbol and signal word

warns of a potentially hazardous situation,

which if not avoided may be fatal or cause

serious injury.

CAUTION!

This combination of symbol and signal word

warns of a potentially hazardous situation,

which if not avoided may cause injury or mate-

rial and environmental damage.

NOTICE!

This combination of symbol and signal word

warns of a potentially hazardous situation,

which if not avoided may cause material and

environmental damage.

This symbol highlights useful tips and recom-

mendations as well as information for efficient

and fault-free operation.

1.3 Personnel qualifications

Personnel responsible for operation, maintenance,

inspection and installation must be able to demon-

strate that they hold a qualification which proves

their ability to undertake the work.

1.4 Dangers of failure to observe

the safety notes

Failure to observe the safety notes may pose a risk

to people, the environment and the units. Failure to

observe the safety notes may void any claims for

damages.

In particular, failure to observe the safety notes

may pose the following risks:

nThe failure of important unit functions.

nThe failure of prescribed methods of mainte-

nance and repair.

nDanger to people on account of electrical and

mechanical effects.

1.5 Safety-conscious working

The safety notes contained in this installation and

operating manual, the existing national regulations

concerning accident prevention as well as any

internal company working, operating and safety

regulations must be observed.

1.6 Safety notes for the operator

The operational safety of the units and compo-

nents is only assured providing they are used as

intended and in a fully assembled state.

nThe units and components may only be set up,

installed and maintained by qualified per-

sonnel.

nProtective covers (grille) over moving parts

must not be removed from units that are in

operation.

nDo not operate units or components with

obvious defects or signs of damage.

nContact with certain unit parts or components

may lead to burns or injury.

nThe units and components must not be

exposed to any mechanical load, extreme

levels of humidity or extreme temperature.

nSpaces in which refrigerant can leak sufficient

to load and vent. Otherwise there is danger of

suffocation.

nAll housing parts and device openings, e.g. air

inlets and outlets, must be free from foreign

objects, fluids or gases.

nThe units must be inspected by a service tech-

nician at least once annually. Visual inspec-

tions and cleaning may be performed by the

operator when the units are disconnected from

the mains.

1.7 Safety notes for installation,

maintenance and inspection

nAppropriate hazard prevention measures must

be taken to prevent risks to people when per-

forming installation, repair, maintenance or

cleaning work on the units.

nThe setup, connection and operation of the

units and its components must be undertaken

in accordance with the usage and operating

conditions stipulated in this manual and comply

with all applicable regional regulations.

nLocal regulations and laws such as Water

Ecology Act must be observed.

nThe power supply should be adapted to the

requirements of the units.

nUnits may only be mounted at the points pro-

vided for this purpose at the factory. The units

may only be secured or mounted on stable

structures, walls or floors.

nMobile units must be set up securely on suit-

able surfaces and in an upright position. Sta-

tionary units must be permanently installed for

operation.

nThe units and components should not be oper-

ated in areas where there is a heightened risk

of damage. Observe the minimum clearances.

nThe units and components must be kept at an

adequate distance from flammable, explosive,

combustible, abrasive and dirty areas or

atmospheres.

nSafety devices must not be altered or

bypassed.

1.8 Unauthorised modification and

changes

Modifications or changes to units and components

are not permitted and may cause malfunctions.

Safety devices may not be modified or bypassed.

Original replacement parts and accessories

authorised by the manufactured ensure safety. The

use of other parts may invalidate liability for

resulting consequences.

1.9 Intended use

Depending on the model, the equipment and the

additional fittings with which it is equipped is only

intended to be used as an air-conditioner for the

purpose of cooling or heating the air in an

enclosed room.

Any different or additional use shall be classed as

non-intended use. The manufacturer/supplier

assumes no liability for damages arising from such

use. The user bears the sole risk in such cases.

Intended use also includes working in accordance

with the operating and installation instructions and

complying with the maintenance requirements.

Under no circumstances should the threshold

values specified in the technical data be exceeded.

1.10 Warranty

For warranty claims to be considered, it is essential

that the ordering party or its representative com-

plete and return the "certificate of warranty" to

REMKO GmbH & Co. KG at the time when the

units are purchased and commissioned.

The warranty conditions are detailed in the "Gen-

eral business and delivery conditions". Further-

more, only the parties to a contract can conclude

special agreements beyond these conditions. In

this case, contact your contractual partner in the

first instance.

REMKO CMF/CMT

1.11 Transport and packaging

The devices are supplied in a sturdy shipping con-

tainer. Please check the equipment immediately

upon delivery and note any damage or missing

parts on the delivery and inform the shipper and

your contractual partner. For later complaints can

not be guaranteed.

WARNING!

Plastic films and bags etc. are dangerous

toys for children!

Why:

- Leave packaging material are not around.

- Packaging material may not be accessible to

children!

1.12 Environmental protection and

recycling

Disposal of packaging

All products are packed for transport in environ-

mentally friendly materials. Make a valuable contri-

bution to reducing waste and sustaining raw mate-

rials. Only dispose of packaging at approved

collection points.

Disposal of equipment and components

Only recyclable materials are used in the manufac-

ture of the devices and components. Help protect

the environment by ensuring that the devices or

components (for example batteries) are not dis-

posed in household waste, but only in accordance

with local regulations and in an environmentally

safe manner, e.g. using certified firms and recy-

cling specialists or at collection points.
