3. CONTROL PANEL LAYOUT
4. USING THE BOILER
- Be sure to keep the indicated pressure on the hydrometer (6) around 1.5 kg/cm
2
.
- Turn on the boiler by pressing the main switch (1).
- Select TIMER or NON TIMER mode by pressing the TIMER switch (2).
NON TIMER MODE:
- Switch on the First power switch (3) you will hear then the pump moving the water. As long as this luminous switch
remains lit it means the first power is generating heat.
The radiators need purging at the highest points of the installation.
- Switch on the switches (4) and (5) if the total power is required. These switches require the switch (3) to be on, to
operate.
- Set the thermostat control (11) to the maximum position.
- Once the required temperature is reached in the thermometer (5) turn the thermostat control anti-clockwise until
the luminous indicators of switches (3), (4) and (5) are off. The temperature will be then automatically maintained.
- This this boiler can be controlled by an external ambient thermostat (not included). This device will switch on and
off the power elements maintaining the ambient temperature.
TIMER MODE:
- Set the timer by rotating the dial clockwise until the correct time is indicated opposite the datum mark.
- Pull the appropriate segments out to set the desired programme. Each segment represents 15 minutes. This
programme will repeat itself every day. The timer may be set to give as many “on” periods of any length as may be
required.
- The
small red switch in the timer means: “A” automatic mode, “0” Always off, “I” always on.
5. SAFETY
The boiler includes safety devices as follows:
- Flow switch. It avoids the power elements to connect in the case the water is not flowing properly.
- Overpressure valve. Should the pressure exceed 3 kg/cm
2
it will drain water.
- Heating safety limiter. Should the heating temperature arise over 100ºC it will disconnect the heating elements. Once the
cause of the overheating is cleared (see troubleshooting section) press the pin under the black cover at (10) when the
boiler cools down.
- Should the boiler be disconnected when the heating elements are on, the thermal inertia could overheat the heating tank.
To avoid this, the pump will remain on even in the case the boiler is off (only when the
thermostats (11) “ask” for heat).
For this reason, it is highly recommended to disconnect the boiler by means of its switch instead of the main electrical
protections. In this case, do not set the thermostat (11) set to the minimum because the pump will be always running.
