1.1 Systems according to VdS
In systems made according to VdS, installation, operation and
maintenance must take place according to VdS guidelines.
Installation, maintenance and repair of Grundfos Fire NKF pump
units must only be carried out by qualified personnel certified by
the German VdS Schadenverhütung GmbH.
2. Applications
The Grundfos Fire NKF pump units are designed for fire systems
for supplying water to hose reels, fire hydrants and sprinkler
systems.
3. Delivery, transport, storage
3.1 Delivery
The pump unit is delivered from factory in an open wooden box or
wooden/cardboard box which is specifically designed for
transport by fork-lift truck or similar device.
3.2 Transport
For lifting the entire pump unit, use the lifting eyes welded on the
base frame and specifically marked. When lifting, the lifting point
should always be above the centre of gravity of the pump unit.
See fig. 1.

3.3 Storage
3.3.1 Pump
Apply a suitable antirust agent on all machined, non-coated
surfaces. If the pump must be stored for more than six months
before start-up, the inner pump components must be treated with
a suitable antirust agent.
The antirust agent must meet these requirements:
•
It must not attack rubber parts.
•
It must be easy to remove.
•
It must be applied according to the instructions of the
manufacturer.
To prevent water, dust, etc. from entering the pump, all openings
must be covered until pipes are connected.
3.3.2 Engine
Engines may be stored for up to 12 months in a dry room after
delivery. It is recommended to protect the engines with an air-
permeable cover. At least once a month, the engine should be
checked for accumulation of dirt or water. Any dirt or water must
be removed immediately.
If the engine is stored for more than 12 months or stopped for
more than six months, it must be protected against corrosion and
damage as follows:
1. Drain the engine of oil, and replace the oil filter. See section
2. Fill the engine housing with MIL-L-21260 oil. See section
3. Replace the fuel filter. See section
4. Separate the engine from the pump.
5. Turn on the engine. See section
. Let the
engine run for one or two minutes.
6. Drain oil and cooling liquid. See sections
9.6 Changing the cooling liquid
.
7. Drain fuel. To do so, loosen the drain screw in the tank bottom
(fig. 29, pos. 9), and collect the diesel fuel in a suitable
container. After draining, tighten the drain screw in the tank
bottom.
8. Place a warning label on the engine: Engine without oil. Do not
start the engine.
Repeat these steps every six months.

Warning
The pump unit must only be used for the
applications mentioned. Any other use is
considered improper use. Grundfos cannot be
held responsible for damage caused by improper
use. The liability rests solely with the operator.
Note
Check the pump unit carefully on delivery, and
transport and store it correctly before
installation.
Warning
When lifting the entire pump unit, never use the
lifting eyes of the individual components.
Use only suitable lifting equipment in proper
condition. See also weight specifications in
section 4.4 Technical data.
During transport of the pump unit, the front door
of the control cabinet must be closed and locked.
