TECHNICAL DOCUMENTATION: EN

1. IMPORTANT INFORMATION

This manual contains important information about preventing possible accidents and damage to Cube units during operation.

Special care should be taken during all actions with the unit and obey to this manual and all technical data. FLOWAIR shall not be

responsible for any omissions and damages caused by them.

In the manual you will find warnings and important tip marked as below:

 Threat of loss of life or

health or permanent

damage to the unit.

 Risk of electric shock.

 Warnings regarding

unauthorized use of Cube

devices. Unsafe practices,

the occurrence of which

may result in property

damage or minor personal

injury.

 Advice and

information on how to

use Cube devices.

SAFETY INFORMATION:

Cube units are compiled with PED 97/23/UE directive (does not apply to Cube R8)

Obey safety instructions under all circumstances!

• It is prohibited to use Cube units for industrial vacuum caused by renovations or other construction

works when dust, harsh or explosive compounds are emitted.

• It is prohibited to use Cube units for rooms’ ventilation system where harsh chemicals are emitted

due to buildings purposes.

• The appliance presents a risk of injury from rotating parts.

• The appliance presents a risk of injury from sharp edges and considerable weight.

• The appliance presents a risk of injury from compressed gas.

• The appliance presents a risk of injury from high and low temperature elements.

• The appliance presents a risk of injury from burns to the refrigerant.

• The appliance presents a risk of injury from burns from high-temperature exhaust fumes.

• Prior to start operations it is essential to switch off the unit with main switch.

• Prior to open casing it is essential to assure that electricity is disconnected and secured against

accidental switching on by other persons.

www.flowair.com | 7

• Cube units must not be used by children or adults with reduced mobility, or limited mental abilities.

• Cube units must not be used by non-trained users or who are not familiar with this manual.

• Cube unit must be used in accordance with its intended use.

• All installation or service works must be done by qualified staff with proper attestations for electricity

and controlled substances (cooling factors).

• Staff should wear suitable protective equipment (helmet, glasses, gloves, etc.).

• During cooling unit operation, some of its parts heat up over 60°C. Precautions shall be taken. Even after

switching off the unit, high temperature may persist which can lead to skin burns.

• Do not touch water exchanger radiators, condenser or vaporizer.

• Do not touch electric heaters with skin under any circumstances.

• Pressure monitoring, filling or emptying cooling systems must be done with existing installation and

proper equipment.

• Installation must be drained from any refrigerant before any dismantling or unsoldering to avoid

explosion risk due to oil and refrigerant splashes.

• Tampering in cooling system by abusing cables or other elements is unacceptable as it may lead to

cooling system decompression and refrigerant leak to atmosphere. The direct contact with refrigerant

may lead to hands or mucous membranes frostbites.

• In order to comply with CE regulations, only original spare parts accepted by the manufacturer can be

used..

• Cube’s cooling system is equipped with safety system protecting against pressure increase, however

containment loss can happen due to safety valve trigger or system unsealing. In such case please leave

the place immediately and call the service. .

• After service works make sure that doors are closed..

• Before unit is launched make sure that all fans and moving parts won’t be interfered by any external

factors.

REFIGERANT:

Cube’s cooling system is filled with R410A – R32/125 (50/50%) refrigerants. It is a HFC group refrigerant not containing chlorine

atoms, therefore it’s ecological and was authorized to use with no limitation.

R410A refrigerant is non-explosive and non-toxic (PED 2nd group), however when contacted with fire, some toxic or corrosive

vapors may appear because of thermal decomposition. Inhaling large amount of this factor may result in narcotic state, oedema,

arrhythmias and in extreme cases – heart attacks and sensitization to adrenaline.

 R410A refrigerant, if in contact with fire can create toxic and corrosive (high moisture) hydrogen fluorine

vapors.

 R410A refrigerant is heavier than air (gas density 0,44kg/m3) therefore in case of leakage it can accumulate

in hollows, displacing oxygen – risk of suffocation.

In case of first aid need due to injuries caused by:

• Do not administer medication to a person in distress.

• Move to fresh air, administer oxygen and apply artificial respiration if necessary. Leave the victim in safe place. Call the

ambulance.

• Do not administer adrenaline or any similar substances.

In case of a frostbite sprinkle with water for at least 15 minutes. Put a sterile dressing and ask for medical help.

RESIDUAL HAZARD

Despite the Cube unit was designed and tested to be fully safe during operation, there is a slight risk connected to improper

use. The residual risk is connected with improper servicing by a user. By obeying the rules mentioned in points 1.10. and 1.11. a

risk is limited to the lowest level, where there will be no risk of life, health or natural environment.

NAMEPLATE

Each Cube unit is equipped with nameplate stuck under the main switch as shown in picture below:

The nameplate contains basic product information such as unit’s code allowing to determine configuration, serial number,

parameters and amount of refrigerant and also basic electrical and air flow parameters.

2. REGULATIONS

2.1. Regulation (EC) No 842/2006 of the European Parliament and the Council

In accordance to UE Regulation 842/2006 regarding some fluorinated gases, Cube user is obliged to control them regarding

leakages according to timetable once a year.

ATTENTION: Not complying with the regulation is an offence and is subject to administrative penalties!

Check that refrigeration equipment must be registered in accordance with the laws in force in your country.

3. GENERAL INFORMATION

3.1. Cube application

The Cube unit, due to its compact construction, has all modules for full air processing like air condition and ventilation.

Depending on unit’s type and size, Cube can be used for air recovery ventilation, heating and cooling in buildings like:

• large industrial buildings.: production or storage halls, printeries, logistic centers,

• commercial buildings (shopping malls, supermarkets, petrol stations, car showrooms),

• public buildings such as: cinemas, theatres, gyms,

• restaurants or fast-food places.

3.2. Device configuration

Cube units can be additionally equipped with heater to increase the temperature of air at outlet. There is a water, electric or gas

modulating heater and an option of a reversible heat pump paired with an electric, water or gas heater. Unit’s size, together with
