The unit is intended to be located on a tabletop or on the lower shelf of a trolley.
3.2. Installation of vacuum pump
A vacuum pump (two-stages with 2-5 m
3
/hour capacity) must be connected to the CoolSafe in order to allow
cryo pumping.
LaboGene recommends the VacuuBrand RZ2.5 rotary vane pump for which a variety of protection
accessories against aggressive materials are available. If the pump outlet/exhaust is not discharged via a
fume hood, an oil mist filter should always be connected. See accessories section for recommended rotary
vane pump and oil mist filter.
Check that the mains supply for the pump is according to the specifications on the type label.
Connect the vacuum hose to the suction side of the pump.
Connect the pump to the vacuum connection pipe on the rear panel of the CoolSafe.
Check the oil level on the pump and fill it if necessary. The oil level sight glass should be 1/2 - 3/4
full.
LaboGene recommends that when the pump is running the gas ballast valve should be open.
