• Place the unit on an even surface on a pad made of non-
flammable material.
F34-MC: The circulator fitted with a stainless steel bridge
is placed on on the back of the bath tank leaving the bath
open on the front side.
• 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 radiates to the environment. (Max. permissible
ambient temperature: 40 °C).
With regard to a disturbance in the cooling loop (leakage),
the guideline EN 378 prescribes a certain room space to
be available for each kg of refrigerant.
The necessary amount of refrigerant is specified on the
type plate.
> For 0.25 kg of refrigerant R134a, a room space of 1 m
required.
> For 0.48 kg of refrigerant R404A, a room space of 1 m
required.
> For 0.49 kg of refrigerant R507, a room space of 1 m
required.
• Set selector dial for cooling machine (19) in position "1" for
operation with MC circulator.
• 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.
Only for water cooled models: (see page 16)
Ensure circulation of cooling water by connecting the tubing to
cooling water inlet and outlet on the rear of the refrigerated
circulator.
Cooling water pressure 3,5 - 6 bar.
Cooling water temperature <20 °C.
