2.2 Storage
2.2.1 Short term storage (less than 2 months)
The machine should be stored in a proper warehouse with a controllable
environment. A good warehouse or storage place has:
•
A stable temperature, preferably in the range from 10 V C (50 V F) to 50 V C
(120 V F). If the anti-condensation heaters are energized, and the surrounding
air is above 50 V C (120 V F), make sure that the machine is not overheated.
•
Low relative air humidity, preferably below 75 %. The temperature of the
machine should be kept above dew point to prevent moisture from condensing
inside the machine. If the machine is equipped with anti-condensation heaters,
they should be energized. Verify the operation of the anti-condensation
heaters periodically. The anti-condensation heaters shall be de-energised
when air temperature inside the machine enclosure exceeds +40 V C. Before
connecting power supply to the anti-condensation heater, check the supply
voltage and power in the Annex 8. Technical Specification or Annex 4.
Connection Instructions. If the machine is not equipped with anti-
condensation heaters, an alternative method of heating the machine and
preventing moisture from condensing in the machine must be used. Machine
can be e.g. heated by using power supply in the machine main terminals.
Required DC voltage is approx. 5% of the rated voltage and current shall not
exceed 30% of the nominal current.
•
A stable support free from excessive vibrations and shocks. If vibrations are
suspected to be too high, the machine should be isolated by placing suitable
rubber blocks under the machine feet.
•
Air which is ventilated, clean and free from dust and corrosive gases.
•
Protection against harmful insects and vermin.
If the machine needs to be stored outdoors, the machine must never be left 'as is'
in its transportation package. To store the machine outdoors:
•
Take the machine out from its plastic wrap.
•
Cover the machine to prevent rain from entering it. The cover should allow
ventilation of the machine.
•
Place the machine on at least 100 mm (4") high rigid supports. This prevents
moisture from entering the machine from below.
•
Provide with good ventilation. If the machine is left in its transportation
package, make large enough ventilation holes in the package.
•
Use anti-condensation heaters or alternative method of heating for heating the
machine and preventing moisture from condensing in the machine
•
Protect from harmful insects and vermin.
2.2.2 Long term storage (2-6 months)
In addition to the measures described in Chapter 2.2.1. Short term storage (less
than 2 months), some extra measures need taken depending on whether the
machine is stored indoors or outdoors.
NOTE: Be careful not to damage the seals or the bearings.
