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 (for "split systems", refer to the installation instructions as the charge must consider the length of the connecting lines),

- IMPORTANT: see paragraph 3.

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).

4.2.1 - INSULATION OF PIPES

• Insulate the 2 tubes separately.

• Use polyethylene sheathing at least 8 mm thick.

• Pay particular attention to water entering along the pipes through the wall.

4.2.2 - CONNECTION TO THE INDOOR UNIT

• According to the side for pipe passage, knock out one cap. Protect the pipes passage from metal sheet edge using the rubber seal supplied or the rubber profile supplied. For sides outlet, the rubber seal has to be cut in 2 parts, as well as the top of it.

• Connect the gas and liquid tubes on the corresponding Flare connectors.

• Screw up by hand.

• Tighten using torque wrenches (to torques shown in the adjacent table).

• Caution: hold the FLARE coupling tight using a wrench.

• Note: If a hydrothermostat is used, the electric heater

accessory is obligatory.

• Theory of operation:

- This remote control contains both a thermostat (settings: 10/35°C) and a hygrostat (settings: 35/ 100% relative humidity).

The hygrostat is used for the "dehumidification" function.

Cooling is triggered by a request from the thermostat or the humidistat.

• IMPORTANT As cooling and heating control signals are provided

by the same change-over contact, there is not neutral zone. The unit thus operates permanently to maintain the required temperature (differential

1K).

Depending on the surrounding conditions, it is possible to encounter simultaneous operation of the heater, requested by the thermostat, and of the air conditioner, requested by the hygrostat (dehumidification).

•An external humidifier, not supplied, may be controlled by the hygrostat by relaying the humidification signal (230 VAC - relay not supplied).
