APPLIANCES FILLED WITH R 407 C

R 407 C

• Fluid R 407 C, as opposed to R22, 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

1 - 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 - (CE Directive 842 / 2006).

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.

•

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 antifreeze 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.

• Operating mode selection:

- the controller is factory configured to control the unit by 1 external:

• On / Stand-by 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, the following configurations are possible by modifying the parameterization: a) Complete shut-down (" OFF") by remote contact (instead of "stand-by").

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

remote "OFF" complete shut-down, the display is off. Only the decimal indicator lamp flashes.

11

GB

b) Selection of the stand-by / cooling mode using the display unit's keys.

In the " CnF" configuration section, change the parameter H27 from 1 (selection by remote contact) to 0 (selection by keypad).

The operating mode is thus selected by successively pressing the "

mode" button (2) according to the following sequence:

---> stand-by ---> cooling ---> stand-by ---

The stand-by mode is indicated by the extinction of the cooling mode indicator lamp.

•

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 (12),

• a minimum stop time (150 seconds).

•

Control hysteresis:

- see the operating diagrams in paragraph 5.4,

- the hysteresis in both cooling mode are factory set at 2k. It is possible to modify it. To do this, change parameter

C03

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

•

"Dynamic" set point:

• The diameter of the pipes must be calculated according to the installation (take care with high head losses).

6.5.3 - ELECTRICAL CONNECTIONS

See the general information about the electrical connections in § 4.2.1.

• The tank is equipped with an 800 W anti-freeze resistance.

• Power supply and control of this resistance shall be separate from all other installation circuits. It must be installed by qualified service personnel who are familiar with this type of equipment and in compliance with local regulations and recognized trade practices.

• Before all operations on the unit, make sure that the power supply is disconnected and locked out.

• The 230 Vac electrical power supply must be fitted with a separate overcurrent protection and disconnect switch in compliance with the rules and regulations in force.

• The power supply wiring must be secured. Use the cable gland located on the resistance cover.

• Route the cable through the grommet located on the front left-hand upright.

• Note 1: The resistance is equipped with an adjustable limiting thermostat set at approximately 5°C.

• Note 2: Power to the resistance must be turned on only

when the circuit is full of water.

•

Note 3: Make sure that wiring is securely clamped in the terminal block and the ground connection is correctly attached.

7 - STARTING

IMPORTANT

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

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

7.1 - CHECK

• That all hydraulic connections are properly tightened and that the hydraulic system functions correctly:

- purge the circuits,

- position of valves,

- hydraulic pressure (1.5 to 3 bar).

• That there are no leaks.

• That the machine is stable.

• That the power cables are well fixed to their connection terminals (loose terminals can cause heat build-up on the terminal board).

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

• That electrical wiring is a safe distance from refrigeration lines.

• 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 unit.

7.2 - STARTING-UP THE UNIT

• Power up the unit.

• Start the unit. See § 5.5.

CAUTION:

As the unit's power supply is three-phase, make sure that the phase rotation order is correct. If the phase order is not respected, the phase order controller KA1 prevents the unit from operating (OK indicator light off) and causes an alarm. To fix this, simply invert the 2 phases.

7.3 - CHECKS TO BE MADE

• Water flow-rate.

The generator is equipped with 1/4 SAE pressure taps upstream and downstream from the circulating pump to enable the pressure loss to be measured using a hydraulic pressure gauge. Use the circulating pump curves in paragraph 10 to determine the water flow rate.

Note:

The generator’s water output must be ensured at all times (particular attention should be paid in the case of control of the terminal units on 2-way valve).

• Pump rotation direction. Should a problem occur, invert 2 phases on the pump's power supply.

• Purge the hydraulic system, with special attention given to the pump.

• Water circuit pressure.

• Filter cleanliness.

• Check the HP and LP pressures (route the pressure tap lines through the hole provided, see

§ 2.2) and check the intensities on the commissioning sheet.

• Check control system operation.

Filling and purge

Draining

IMPORTANT:

• The unit's electronic control features a frost protection device that automatically starts the water circulating pump depending on the outside temperature (threshold: 0°C), even if the unit is turned off.

• When the unit is turned on, It is thus important to make sure that the hydraulic circuit is ready to operate (purge, water pressure, position of valves).

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

If the installation includes a supplementary boiler, make sure that the antifreeze used will not damage it.

8 - MAINTENANCE INSTRUCTIONS

IMPORTANT NOTE

• Before doing any work on the installation, make sure that it is switched off and locked out.

• 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.

GB

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,

- 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.),

- verification of the unit's safety valve (and that of the tank, if any).

8.2 - GENERATOR SHUT-DOWN DURING WINTER

•

2 possibilities:

1) Drain the unit and disconnect the power supply.

2) Unit full of water and power on: as the unit is equipped with an antifreeze device which actuates the water circulating pump when the temperature drops below zero, it is imperative to ensure that the water can circulate within the unit.

9 - TROUBLESHOOTING

• All maintenance and servicing operations on the refrigerating circuit must be conducted in accordance with standard trade practices and safety rules: recovery of the refrigerant, inert shielded (nitrogen) brazing, etc…

• All brazing operations must be conducted by qualified welders.

• For equipment loaded with R 407 C, refer to the specific instructions at the beginning of the installation manual.

• This unit is equipped with pressurized equipment, for example piping.

Use only genuine parts listed in the spare parts list for replacing defective refrigeration components.

• Pipes may only be replaced by copper tubing in compliance with standard NF EN 12735-1.

• Leak detection, in the case of pressure testing:

- Never use oxygen or dry air, as the risk of fire or explosion is present.

- Use dehydrated nitrogen or a nitrogen and refrigerant mix indicated on the manufacturer's plate.

- For units equipped with pressure gauges, the test pressure must not exceed the gauges' maximum allowable pressure rating.

• All part replacement with other than genuine parts, all modifications of the refrigerating circuit, all replacement of refrigerant by a fluid other than that indicated on the manufacturer's plate, all use of the unit outside the application limits defined in the documentation, shall result in the cancellation of PED CE marking compliance which shall fall under the liability of the individual who carried out these modifications.

• The technical information, relative to the safety requirements of the various applicable directives, is indicated on the manufacturer's plate of the unit and mentioned on the 1 st page of this manual.
