6. Mechanical installation
This section describes the installation of a complete pump set.
6.1 Pump set location
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.
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
– 0.1 m
3
/min per kW of engine gross power
For further information, see the installation and operating
instructions for the engine.
Air-cooled engine
To calculate the minimum air flow through the pump room, see
the installation and operating instructions for the engine.

Ventilation of the pump room
Install louvres on-site that open as soon as the engine starts.
The louvres must be dimensioned according to EN 12845.
This will ensure an adequate amount of fresh air to remove
engine heat and combustion from the room.
Warning
You must not disconnect any parts of the entire
pump set without guidance by Grundfos Service.
Warning
Use personal protective equipment when
carrying out commissioning, maintenance and
test in order to prevent or minimise the risk of
personal injury if other measures cannot be
taken.
Such equipment must comply with the
requirements specified by the main contractor or
operator of the operations room or the site in
question.
Minimum requirements are well-fitting clothing,
protective gloves, hearing protection, safety
goggles and safety shoes.
Caution
The installation should be carried out by qualified
staff in accordance with the following
instructions.
Note
Observe also the instructions in the standards
applying to this product.
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.
Warning
The area around the pump set must be cleaned
and cleared to avoid personal injury due to
slipping and falling.
