Installing in a vacuum system
➨ Remove the transportation safety device (foam insert) in
the cove of the cold trap.
➨ Grease the ground joints prior to use with vacuum grease.
➨ Assemble the cold trap to a base plate or fixate at a stand
mounting.
➨ Connect the cold trap to the vacuum pump and the recipi-
ent.
☞ Prevent mechanical stress at the connection due to tensile
force or vibrations.
➨ Close the condensate drain valve.
☞ Due to the O-ring, the valve seals already at small contact
pressure of the valve face.
PC 3 with GKF 1000i:
➨
Assemble the separately packed vacuum hose (1) be-
tween the cold trap (connection of vacuum pump) and the
inlet of the rotary vane pump / Chemistry HYBRID pump
RC 6 (small flange connections NW 16, see figure).
During operation
➨ Remove cover and plastic insert of the cool trap. Fill cool-
ant into the coolant chamber.
➨ Switch on the vacuum pump immediately after filling in the
coolant. Open valve (2) between vacuum pump and cold
trap (PC 3). Do not pump condensable vapours or gases
until the vacuum pump has reached its operating tempera-
ture.
☞ The coolant consumption is increased if the condensate
chamber is not evacuated.
☞ The lifetime of the coolant may be restricted due to icing in
case of high operating pressures.
➨ Vent the cold trap for de-icing or draining of condensate.
☞ Check coolant level at appropriate intervals.
Use and operation
Check the level of condensate at appropriate intervals
and if necessary drain condensate via the condensate
drain valve. Vent the system prior to opening the drain
valve!.
- Wait until the condensate has liquidised, if necessary.
• Ensure that condensate drain tubing and collecting
equipment are chemically resistant against the con-
densate.
