5.3 Filling the store with fuel

Note the following when loading the machine with fuel:

❒ Only use permitted fuels! 

⇨ See "Permitted fuels" [page 7]

❒ Remove foreign bodies from the store before filling

 
NOTICE! Systems in which the fuel is delivered by tanker and is blown into the store
space must be fitted with a rotary valve.

 

CAUTION

Entering the store space when the system is switched on
Risk of injury due to automatic startup of system, particularly the discharge

system!

Therefore, before entering the fuel store:

❒ Switch off the power supply to the entire system

➥ Depending on the model via boiler, expansion switch cabinet, etc.

For blowing in fuel the following precautions also apply:

 

CAUTION

Blowing in fuel when the boiler is switched on:
The underpressure generated from blowing in fuel can lead to smoke being

sucked back into the store if the boiler is switched on. Possible excess pressure

could cause smoke to escape into the installation room, possibly resulting in injury

and damage!

Therefore, before blowing in the fuel:

❒ Switch off the power supply to the entire system

➥ Depending on the model via boiler, expansion switch cabinet, etc.

❒ Allow the system to cool for at least two hours
