BY-PASS CALIBRATION OPERATIONS FOR 5-6-7-8 TYPES AND 13-14-15-16 TYPES
- - Switch on the appliance.
- Wait for the unit operation to get stabilized
- Check the heat rise between system delivery and return which must be between 4°C and 6°C
- If it is not so, operate the calibration by-pass, opening it to increase the heat rise or closing it to decrease the heat rise
- After adjusting the by-pass, bring the unit back to steady state and check if the heat rise between system delivery and return is between
4°C and 6°C.
- Replace the inspection panel
After operating the by-pass valve (to be installed downstream of the machine for 5-6-7-8 types and 13-14-15-16 types), wait for the
unit operation to get stabilized and repeat the check .
Should not it be possible to regulate the heat rise between system delivery and return within 4÷6°C, check the system load losses
and compare them with the flow rate-available lift chart of the pump on page 8.
A heat rise over 6°C entails the risk of ice forming in the plate heat exchanger
For the by-pass location, refer to the hydraulic diagram on page 21
It is not allowed to operate the unit with a heat rise over 6°C.
SWITCHING THE EQUIPMENT ON AND OFF
To SWITCH ON and OFF the “COOLING” and “HEATING” functions, use the CONTROL PANEL installed on the machine, or the two “SO”
ON-OFF and “SEI” SUMMER-WINTER REMOTE SWITCHES, if installed..
If the “Er 20” indication appears on the display in this first phase, please follow the instructions i:
- Check the water flow rate and the connection with the flow switch terminals 9 and 10.
To access the control panel, open the relevant door:
- Remove the lock screw
- Simultaneously press the (A) points and lift the door
After operating the control panel:
- Close the door and replace the lock screw.
