5. Preparations
5.1. Installation
• Place the unit on an even surface on a pad made of non-flammable
material.
• Press down the castor levers on model FT902, FT903.
• The place of installation should be large enough and provide sufficient
air ventilation to ensure the room does not warm up excessively
because of the heat the instrument rejects to the environment.
For a fault (leakage) in the refrigeration system, the standard EN 378
prescribes a certain room space to be available for each kg of
refrigerant.
> For 0.52 kg of refrigerant R404A, 1 m
3
of space is required.
> For 0.423 kg of refrigerant R452A, 1 m
3
of space is required.
> For 0.68 kg of refrigerant R23, 1 m
3
of space is required.
• The instrument should be set up at a frost-proof and dry location.
• The ambient temperature must not exceed 35 °C (32 °C at units with
R452A).
• Keep at least 20 cm of open space on the front and rear venting grids.
• Do not set up the unit in the immediate vicinity of heat sources and do
not expose to sun light.
• Before operating the unit after transport, wait about one hour after
setting it up. This will allow any oil that has accumulated laterally
during transport to flow back down thus ensuring maximum cooling
performance of the compressor.
