Translation of the original operating manual
The cooling water demand is controlled automatically by the cooling water
control valves in line with the load of the refrigeration units. For
preadjustment, the cooling water control valves are equipped with an
adjusting knob which can be adjusted with the aid of a screwdriver. The
preadjustment must ensure that, under the present cooling water conditions
(pressure and temperature), the pressure on the high-pressure side of the
refrigeration circuit is approximately 13 bar under no-load conditions. The
pre
ssure difference (∆p) must be 1.5 bar at a minimum (see chapter 10 -

If the supply with cooling water is insufficient, the pressure inside the
refrigeration system will rise and the refrigeration unit will be switched off
via the overpressure switch. The error will be indicated by the control
system of the freeze-dryer.
Please contact our specialists if the cooling water temperature is higher
than +20°C.

WARNING
Risk of poisoning/infection caused by vacuum pump exhaust gases
The exhaust gases of the vacuum pump may contain harmful substances
originating from the product.
Inhalation may cause severe damage to health.
• User the freeze-dryer only if it is equipped with a pipe that is properly
connected to the outlet of the vacuum pump/exhaust filter (oil mist
separator) and led to the outside via the roof!
• Depending on the product that is dried in the freeze-dryer, it may be
necessary to install a suitable filter system in the exhaust gas pipe!
Compliance with the local rules and regulations concerning the
