During transport in a closed container the refrigerant charge
must be transferred to the condenser. This prevents that
the pressure in the evaporator reaches the valve calibration
pressure during transport (if this happened, the charge
would be evacuated to the atmosphere and the unit would
be empty when it arrives on site). For this reason the charge
is transferred to and stored in the condenser, and the liquid
and discharge line valves are closed.
The following precautions must be taken during installation:
• Ensure that there is sufficient water flow in the
evaporator.
• Energise the unit.
• Open the liquid line valves.
• Open the EXV to return the charge to the evaporator;
pressure equalisation must be verified by a quick test
procedure.
• Open the discharge line valve.
11.5.2 - Units equipped with hydronic kit
If the antifreeze concentration exceeds 30%, it is recom-
mended to reduce the brine flow rate to prevent over-
loading and over-heating of the motor.
The flow rate limits are given in the table below:
For an application between 32 and 40% and operation at
an outside air temperature between 40 and 48°C use linear
interpolation.
IMPORTANT: Never use a glycol concentration of less
than 20%, as the brine will become aggressive and there
will be an increased risk of corrosion of the cast iron
parts of the hydronic kit.
