2.10. Electricity check list
Check that
• all phases going to the switchboard are in the correct phase sequence
• tension difference between phases is 400V
• the main fuse size is correct
• the fuse size of ground source heat pump is correct (slow)
• as needed, the current control is installed in to the electric control panel
2.11. Operating switches
• Q1 - Main switch
• F3 - Control current
• S1 - Heating on/off
• S2 - Heat distribution pump 1
• S5 - Heat distribution pump 2
• S3 - AUTO - 0 - MAALÄMPÖ
• S4 - Condenser pump and magnetic valve
• QM1 - Compressor
• QM2 - Brine pump
2.12. Before startup
Before startup, check that:
• the heating system has been connected, filled and deaerated appropriately
• the ground loop has been installed, filled and deaerated appropriately
• electrical connections have been made appropriately
• all sensors has been installed
• fuses are in position:
on
2.13. Startup
• Turn on the main switch.
• Press down black motor protection switches QM1 and QM2.
• Turn the switch S1 on.
• Turn the AUTO - 0 - MAALÄMPÖ switch to the position MAALÄMPÖ.
• Start the ground source heat pump with the switch F3.
• Check the rotation direction of brine pumps. Check the phase rule in case of the incorrect rotation direction.
The Lämpöässä ground source heat pump starts. If the installation is carried out carefully and in accordance with the
instructions provided the system will work faultlessly from the very beginning.
