R 407 C

• Fluid R 407 C is not a pure fluid but a blend composed of:

- 23% R 32 + 25% R 125 + 52% R 134 A.

• The compressors approved for operation with this fluid are filled beforehand with polyalcohol oil. Contrary to mineral oil, it is very hygroscopic: it absorbs the humidity of the ambient air very quickly. This can modify its lubricant properties and lead in time to the destruction of the compressor.

MAINTENANCE INSTRUCTIONS

- Never add oil to the appliance; the compressor is filled with polyalcohol oil, a special oil which cannot tolerate the presence of other oils.

2 - The instruments used for:

- filling,

- pressure measurements,

- emptying under vacuum,

- recovering the fluid,

must be compatible and only used for the R 407 C fluid.

3 -

The weight of the refrigerant contained in the storage bottle must be checked constantly. Do not use it from the moment the remaining weight is less than 10% of the total weight.

4 - In the case of a new charge:

- do not use the charging cylinder,

- use a balance and a dip pipe type R 407 C cylinder,

- charge the weight of R 407 C as per the value indicated on the unit’s identification plate,

- IMPORTANT: see instruction 3 above.

5 - The charge must be undertaken in liquid phase. 6 - In case of leakage, do not complete the charge: recover

the remaining refrigerant for recycling and perform a total charge. Recovery, recycling or the destruction of the fluid must be done in compliance with the laws in force in the country concerned.

7 - If the refrigerant circuit is opened, you must:

- avoid the entry of air into the circuit as much as possible,

- replace the filter drier,

perform the "vacuum operation" at a minimum level of

0.3 mbar (static).

8 - Do not release R 407 C fluid into the atmosphere. This

fluid is a fluorinated greenhouse gases, covered by the Kyoto Protocol with a Global Warming Potential (GWP) = 1653 - (EC Directive 842 / 2006).

SUMMARY TABLE OF ALARMS

(*) The insufficient heat exchange alarm is activated if the temperature difference between the water inlet and outlet (after the

compressor has been operating for a few minutes) is insufficient (coolant charging problem, three-phase compressor running “backwards”, jammed switch-over valve, faulty temperature probe, problem on the equipment; etc.).

5.8 - SPECIAL OPERATING FEATURES

• Reduction of water volume

- the controller uses a self-adapting algorithm that analyses the compressor's operating time and can indicate deviations of the current set point (and the corresponding hysteresis) in case of too short operating times (in order to extend the operating times),

- for special applications, in which case the dimensioning of the unit and the circuit are carefully designed, this function can be deactivated. To do this, set the parameter

C08 to 0 in the "CP" section of the parameterization menu.

• Defrosting:

- if the temperature detected by probe SD3 drops below the frosting temperature (dependent of the outside temperature), a time counter is activated. This counter records the operating time in icing conditions. This status is indicated by the flashing frosting indicator lamp (

7),

- after an accumulated operating time of 30 minutes, a defrosting operation is launched (inversion of the refrigerating cycle and shut-down of the fan) until the temperature detected by probe SD3 rises above the end of frosting temperature threshold. The defrosting phase is indicated by the (steady) illumination of indicator lamp (

7).

Note:

The ventilation can restart after defrosting is completed to prevent excessive pressure build-up. For special climatic conditions, the factory-set time counter value of 30 minutes can be adjusted.

To do this, modify

parameter

d03 in the defrosting section "dFr".

• Evaporation pressure regulation:

- the ECH controller is equipped with a variable voltage regulator for the fan's power supply,

based on temperature information (read by the

SD3 probe located on

the evaporator), the controller varies the supply voltage of the electric fan according to the diagram opposite.

•

Circulating pump control

- the pump is actuated when the unit operating or in stand-by mode,

- the pump is stopped when the unit is completely

OFF. The shut-down

of the pump is delayed 1 minute after the compressor stops.

An anti-

freeze device forces pump operation if the outside temperature (probe

SD4) drops below 0

°C,

- an "anti-sticking" device forces pump operation (if stopped) for 3 seconds every 24 hours.

• Condensate tank heating cord control:

Actuated if the outside temperature (probe

SD4) drops below 0

°C (regardless the unit's operating mode). The "heating

element" indicator light (8) illuminates.

•

Operating mode selection:

The regulator is configured in the factory for On/Stand-by

control using an external contact

- In stand-by mode, the circulating pump continues to function.

Note:

It is possible to shut the unit down completely (circulating pump stopped) by pressing the ON/OFF button (1).

- This configuration is adapted to system applications,

- For other applications, complete shutdown (“

OFF”) by remote contact (instead of stand-by) can be achieved by

modifying the configuration.

In the "

CnF" configuration section, change the parameter H20 from 7 (remote stand-by) to 4 (remote OFF). In the

case of remove "OFF" complete shut-down, the display is of

f. Only the decimal indicator lamp

flashes.

The stand-by mode is indicated by the extinction of the heating mode indicator lamps.

•

Pre-ventilation:

- Generally speaking, in order to condition the air heat exchanger, the fan always starts at full speed a few seconds before the compressor.

•

Anti short-cycle time delays:

- The compressor control features a time delay system in order to respect:

• a maximum number of starts per hour (10),

• a minimum stop time.

•

Cycle inversion valve:

- The valve is actuated during defrost cycles.

•

Control hysteresis:

- See the operating diagrams in paragraph 5.4.

- The factory setting for hysteresis in heating mode is 4k. Modification is possible. To do this, modify parameter

C04

(heating hysteresis) in the compressor section "CP".

7.1 - CHECK

• That hydraulic connections are properly tight and that the hydraulic circuit functions correctly:

- purge of circuits,

- position of valves,

- hydraulic pressure (2 bar).

• That there are no leaks.

• That the machine is stable.

• That the power cables are well fixed to their connection terminals. Terminals that are poorly tightened may cause overheating and malfunctions.

• That the electric cables are well insulated from any sections of sheet metal or metal parts which could damage them.

• That probe, control and power cables are properly separated.

• That the machine is earthed.

• That there are neither tools nor other foreign objects in the units.

7.2 - WATER QUALITY

• In order for the heat pump to operate under good conditions and provide optimum performance, it is essential to ensure that the system’s water circuit is clean. If the water circuit becomes clogged, this will significantly affect the machine’s performance.

The circuit must therefore be cleaned with suitable products in compliance with current standards as soon as

it is installed, both for new and renovation work. W

e recommend the use of products which are compatible with all metals and synthetic materials and approved by of

ficial

bodies. Recommendations regarding water quality:

- PH: 6 to 9

- TH: 10 to 20°F

Dry material in suspension: < 2 g/l

Granulometry: < 0.4 mm

- Chloride: 50 mg/l maximum

Conductivity: 50 to 500

µS/cm

- Resistivity: 1 to 10 kΩ

- Fibre: no fibres

Any disorder which may occur on our machines due to the poor quality of the fluid in the installation will not be covered by the TECHNIBEL warranty.

Page 14

7.3 - STARTING-UP THE UNIT

• Power up the unit.

• Turn the water on.

• Start the appliance (see paragraph 5).

CAUTION: On three-phase units, make sure that the phase rotation order is correct. If the rotation order is not respected, the compressor will turn backwards (and make an abnormal noise). T

o fix this, simply invert the 2 phases.

7.4 - CHECKS TO BE MADE

• Water flow-rate.

• The generator is equipped with 1/4 SAE pressure taps at the circulator inlet and outlet, to enable the pressure drop to be measured using a hydraulic pressure gauge. Use the circulator curves in paragraph 10 to find the water flow rate.

Note: In order for the device to operate correctly, there must be a constant flow of water. It must correspond to the data

given in the circulator graphs (in paragraph 10), particularly for the high temperature application (water outlet greater than 55° C).

• Hydraulic circuit pressures.

• Control system operation.

• Sealing of the cooling circuit (according to the decree of 7th May 2007).

IMPORTANT: If antifreeze is added (monopropylene glycol), a minium rate of 15% to 20% is needed to avoid any risk of corrosion.

• The LP pressure switch cuts at 0.5 bar.

• The HP pressure switch cuts at 29 bar.

8 - MAINTENANCE INSTRUCTIONS

8.1 - MAINTENANCE

All equipment must be properly maintained in order to provide optimum performance over time. Faulty maintenance can result in the cancellation of the product guaranty. Depending on the products, maintenance operations consist in the cleaning of filters (air, water), internal and external exchangers, casings, and the cleaning and protection of condensate tanks.

Treating odours and the

disinfection of room surfaces and volumes also contributes to the cleanliness of the air breathed by users.

•

Carry out the following operations at least once a year (the frequency depends on the installation and operating conditions):

- check for leaks on the refrigerating circuit (according to the order of 7th May 2007).

- check for traces of corrosion or oil stains around the refrigerating components,

inspect the composition and the condition of the coolant and check that it does not contain traces of refrigerating fluid,

- cleaning the exchangers,

- checking the wear parts,

checking the operating instructions and points,

- check the safety devices: particularly check that the high and low-pressure controllers are properly connected on the refrigerating circuit and that they disengage the electrical circuit if triggered,

- de-dusting the electrical equipment cabinet,

checking that the electrical connections are secure,

- checking the earth connection,

- check the hydraulic circuit (clean the filter, water quality, purge, flowrate, pressure, etc.).

• Before carrying out any work on the installation, make sure that it is switched off and that access to it is prevented.

• Also check the discharge of the compressor capacitor for the single-phase voltages.

• Any work must be carried out by personnel qualified and authorised to work on this type of machine.

• Prior to all maintenance and servicing on the refrigerating circuit, one must first shut down the unit then wait a few minutes before installing temperature or pressure sensors. Certain equipment, such as the compressor and piping, may reach temperatures above 100°C and high pressures may lead to serious burns.
