Before carrying out any work on the unit, power the unit down to avoid injury from electrical current.

Check that the unit is isolated and ensure that the appropriate point of the unit for the on-

site power supply is secured against being switched back on.

DANGER OF SCALDING!

Before performing work on the valves or the inlet or outlet pipes, seal o󰀨 the heating or cooling

medium inlet to prevent scalding. Do not commence work before the heating medium has cooled

down.

DANGER OF ROTATING UNIT PARTS!

Rotating fan wheels can cause injury! Before performing any work on the unit, ensure that

it is powered down. Ensure that the appropriate point of the unit for the on-site power

supply is secured against being switched back on.

Fan Coil Unit –Large Air Flow & High Static Pressure Type

1.Safety and User Information

Safety instructions

The Large Air Flow &High Static Pressure fan coil units are developed and manufactured

in accordance with the state-of-the-art technological standards and established technical

safety norms and regulations. The Large Air Flow & High Static Pressure fan coil units comply

with the Machinery Safety Directive.

The Large Air Flow & High Static Pressure fan coil units are reliable and satisfy high

quality standards. This product range combines advanced technology with ahigh level of user

friendliness and ease of maintenance.

However, all fan coil units inevitably pose residual risks of injury to the user or third parties

or material damage to the unit or other objects. For this reason, you should take into account

and follow all safety instructions. Ignoring these safety instructions is connected with risks to your

health and safety, can lead to the environmental damage and/or extensive material damage.

Observing the safety instructions in the operation manual will help you to avoid risks,

ensure economical operation of the unit and enjoy full benets of the product.

The safety aspects covered by this Chapter are valid for the entire operation manual. To ensure our

own safety consider the following safety instructions.

DANGER OF OVERHEAD LOADS!

Wear ahelmet and safety boots to prevent injury from falling components, especially when tting the

unit to the ceiling. Ceiling installations should always be performed by two people.

PERSONAL INJURY!

Always wear protective gloves when moving or tting the unit to avoid injury from sharp edges.

Important notes

The fan coil units are end units of chilled/hot water air conditioning system featuring high

profession and high technological requirement, therefore, the unit shall be installed, operated and

maintained only by qualied, specially trained and authorized sta󰀨.

Proper use

Large Air Flow &High Static Pressure fan coil units are exclusively designed for ventilating, hea-

ting, ltering and cooling purposes. Chilled water/Hot water may be used as the medium. The

following limit values apply to the medium for operating Cu/Al heat exchangers:

DAMAGE TO THE UNIT!

On open systems (e.g. when using well water observe the limit values stated in above table), the

used water should additionally be cleansed of suspended matter using alter which should be

located at the inlet. Otherwise there is arisk of erosion by suspended matter.

You also have to ensure that the unit is protected from dust and other substances that can cause

acidic or alkaline reaction when combined with water (aluminum corrosion).

– The Large Air Flow &High Static Pressure fan coil units may only be used indoors.

– The Large Air Flow &High Static Pressure fan coil units is suitable for ceiling installation. The

unit is considered to be used in an improper manner if it is applied for other purposes

or a purpose that is not covered by the scope of the given operation manual. The

manufacturer or supplier is not liable for any resulting damage: the user alone bears the full risk.
