9 SAFETY INTERLOCKS
The diesel boiler included in the module has two types of safety interlocks:
9.1 Temperature safety interlock
This locking occurs when the boiler exceeds a temperature of 110°C. To unlock it, press the button
on the safety thermostat
(24)
after first removing the button cover.
9.2 Burner interlock
This cut-out is indicated by the light for the locking of the burner
(1)
. This occurs as a result of an
anomaly in the burner or in the fuel installation. To lock it, press the illuminated button that lights
up on the burner.
If any of these cut-outs occur repeatedly, call your nearest official Technical
Assistance Service.
10 MODULE MAINTENANCE
To keep the module in perfect working condition, a review must be carried out annually by personnel
authorised by
DOMUSA TEKNIK.
Module and flue maintenance
The most important aspects to be checked are as follows:
- The water pressure in the heating/air conditioning installation,
when the water is cold
, must
be between 0.1 and 0.15 MPa (1 and 1.5 bar). If it is not between these values, it must be filled
until they are reached.
- The control and safety devices (thermostats, gas valve, etc.) must operate correctly.
- The burner and the inside of the boiler chamber must be clean. Soft brushes or compressed air
are recommended for cleaning the boiler, to prevent damage. Do not use chemical products.
- The expansion vessel must be full, in accordance with the specifications on the vessel plate.
- Check the tightness of the water installations.
- The flues must be free of any obstacles and have no leaks.
- The circulation pumps and diverter valves must not be blocked.
10.1 Cleaning the boiler
To keep the boiler in perfect working order, we recommend cleaning the boiler chamber,
exhaustion ducts and condenser on a yearly basis. A cleaning brush of a suitable size for cleaning
the inside of the exhaustion ducts is supplied with the boiler for this purpose. This brush is located
at the rear of the boiler, beside the condenser.
The combustion chamber and exhaustion ducts should not be cleaned using chemical products
or hard steel brushes
. After any cleaning operation has been carried out, it is important to run
several ignition cycles to check all the elements are functioning correctly.
10.2 Anti-frost protection
In areas subject to very low temperatures, it is advisable to take precautions in order to avoid
damage to the boiler by frost. It is advisable to add anti-freeze to the water in the heating circuit. If
the boiler is to be out of use for long periods of time, we recommend
draining all the water from
the boiler.
10.3 Characteristics of the water
In areas with water hardness of over 25-30ºF, treated water must be used in the heating/air
conditioning installation to avoid any scale deposits on the module.
