CHECKS AND SETUP BEFORE START UP
Set-up conditions
•
External power supply isolated
Procedure
1. Remove the boiler front panel, refer to
"Removal and In-
stallation of the Access Panels" on page 14
.
2. Set the internal MCB to OFF (See ML book).
3. Check all electrical connections for tightness.
4. Ensure all internal relays, contactors, etc. are secure on the
DIN rails.
5. Set all the control panel control switches to OFF.
6. Check the power stage delay timer settings:
•
Adjustment screw (
A
) is factory set to the “1 to 10 min.”
position which is the optimum setting for the boiler. The
timer can be adjusted from 0.1 sec. to 10 hours.
•
Adjustment screw (
B
) is used to set the DELAY ON time
of the following stage contactors, the available settings
are in 1 minute increments if A is set to 1 to 10 minutes.
•
This function is particularly useful in areas where gradu-
al switching of electrical load is required and the result-
ing maximum demand kept to a minimum. The timers
add to the flexibility of the installation but must be opti-
mised by a qualified engineer. The nominal setting is “1”.
7. Set the control thermostat to the desired temperature.
Cold water
Hot water
FILLING THE SYSTEM
If the system is fitted with an external
hot water tank, first put the DHW circuit
under pressure before pressurizing the
heating (primary) circuit. Refer to the hot
water preparation tank manual for more
information.
Set-up conditions
•
External power supply isolated
•
DHW circuit (if any) under pressure
Filling procedure
1. Open the isolating valves (1).
2. Make sure that the drain valve (2) is tightly closed.
3. Open the filling valve (3).
4. Make sure the air vent is open, as required.
5. Once the system is bled from air, bring the pressure to the
static pressure between 1.5 bar and 2 bar.
6. Close the filling valve (3)
