Coolant load
Depending on the model of the heating module, the installer has to fill a minimum load
of refrigerant according to the following table:
Standard
Models
Refrig.
Minim.L
oad (kg)
HTM-24E
R407C
3,1
IMPORTANT: Refrigerant 407C, is a zeotropic mix that is composed by 3 different
components. For this reason, the refrigerant has to be in liquid state at the moment of the
loading to ensure the homogeneous charge of each compound.
Do the load always taking the refrigerant of the bottom of the recipient
Load the refrigerant ALWAYS WITH THE MODUEL SWITCH OFF and using the load port
located at the high pressure line, always in liquid state.
Once the initial load has been done, make hydraulic and electric installation.
When the heating module has been connected to the grid, switch on the grid voltage via
the line circuit breaker.
DO NOT ACTIVE TH SYSTEM BY THE THERMOSTAT: The heating module must be
switch off at least 10 minutes, while the crankcase heater is heating the compressor in order to
avoid any risk of liquid hammer in the compressor.
After this period, switch on the heating module using the thermostat key (or the switch)
and start the refrigerant load until achieve the appropriate load. For this issue, check the
ambient temperature and load refrigerant until the evaporation pressure (indicated in the
pressure gauge) match with the values at the table below:
