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 and 93/68 EEC.
1 - APPLICATION - USE
•
Chilled water or hot water generator for air conditioning or heating of rooms for
terminal unit and boiler overhaul
applications.
NOTE : The electronic control parameterization is factory-set for terminal unit and boiler overhaul applications.
R 410 A
• R 410 A is a high-pressure refrigerant (+ 50% in relation to
R 22 and R 407 C).
• 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 410 A fluid.
Note: the pressure taps of the refrigerating circuit are
5/16 SAE (1/2 - 20 - UNF)
3 - In the case of a new charge:
- the charge
must be undertaken in liquid phase,
- use a balance and a dip pipe type R 410 A cylinder,
- charge the weight of R 410 A 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).
4 - 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.
5 - If the refrigerant circuit is opened, you must:
-
avoid the entry of air into the circuit as much as
possible,
- replace or install a drier,
- perform the “vacuum operation” at a minimum level of
0.3 mbar (static).

IMPORT
ANT:
Use monopropylene glycol.
A minium rate of 15% to 20% is needed to avoid any risk of
corrosion.
8.1 - PRINCIPLE OF USING THE CURVES
•
Choose the percentage of glycol according to the minimum
temperature to protect the hydraulic circuit against frost and
determine the coefficients to be applied to the power, the water flow
rate and the pressure drop.
8.2 - EXAMPLE
•
Protection at an external temperature of -15°C, which gives 30%
glycol ("Freezing points" curve).
•
The "Reduction of cooling capacity" curve gives the coefficient to be
applied to the refrigerating capacity (0.94).
• The "Water flow" curve gives the coefficient to be applied to the water
flow rate (1.113).
• The "Pressure drop" curve gives the coefficient to be applied to the
pressure drop (1.19).
Curves valid for temperature control on the water intake.
