Note
applying to this product.

6.1 Pump set location

Warning
Pump set with diesel engine:
Ensure an adequate supply of air for the combustion
engine and an adequate removal of heat and
exhaust.
Non-compliance or impairment of the ventilation or
exhaust system may result in suffocation of people.
Lubricants, fuels or other highly volatile or
combustible materials must not be stored near the
diesel engine. Such materials must be stored in a
suitable, separate room.
Place the pump set in a dry, frost-free, well-illuminated and well-
ventilated location. The pump set, primarily the control cabinet,
must not be exposed to direct sunlight.
Allow sufficient clearance around pump and engine to enable
maintenance and operation.
Warning
The area around the pump set must be cleaned and
cleared to avoid personal injury due to slipping and
falling.

6.1.1 Ventilation
For optimum room ventilation, the air supply ventilator and air
discharge must be located on opposite walls. The pump room
temperature must be minimum 10 °C.
Ventilation must be provided for the following functions:
1. To control the maximum temperature to 25 °C at the engine air
filter inlet with the engine running at rated load.
2. To supply air for engine combustion.
3. To ensure adequate cooling for air-cooled engines.
4. To remove any hazardous vapour.
5. To ensure sufficient oxygen in the breathing air.
Water-cooled engine
You can use the following as a rule of thumb when removing
radiated heat from the engine.
Minimum air flow through the pump room:
3
– 0.1 m /min per kW of engine gross power
For further information, see the installation and operating
instructions for the engine.
Fig. 6 Ventilation of the pump room
Install louvres on-site that open as soon as the engine starts.
The louvres must be dimensioned according to NFPA 20. This will
ensure an adequate amount of fresh air to remove engine heat
and combustion from the room.
