MARKING
This product marked conforms to the essential requirements of the Directives:
- Low voltage no 2006/95/EC.
- Electromagnetic Compatibility no. 89/336 EEC, modified 92/31 EEC and 93/68 EEC.
- Pressure Equipment Directive No. 97/23/EC.
1 - APPLICATION - USE
• Air cooled type chilled water generator intended for climate control in buildings.
• Single package unit, factory assembled and tested.
•
Designed for outdoor installation.
• Supplied fully charged with R 407 C refrigerant.
• Convenient hydraulic and electrical connections.
• Practical service access via removable panels.
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 W
arming Potential
(GWP) = 1653 - (CE Directive 842 / 2006).
