All CoolSafe models utilize low temperature refrigeration to -55°C, -95°C, -100°C or -110 °C and
under no circumstances should the cold surfaces of the condenser be touched whilst switched on,
in operation or in the de-icing process.
Do not handle, move or service the vacuum pump whilst in operation or if it is switched off, until it
has cooled down to ambient temperature. (See paragraph regarding maintenance & changing of oil
in the vacuum pump).
It is advisable that safety glasses and personal protective garments are worn by all users of the
equipment.
CoolSafe Basic or Pro models 95-15 and 100-9 are fitted with castors, the front pair being lockable.
Once located in the position conducive to both the safety of the laboratory environment and
personnel, it is advised that the castors be in the locked position.
The safety system is designed according to safety requirements for electric equipment, control and
laboratory use (EN 61010-1), which assumes that two separate faults do not occur simultaneously.

Installation
3.1
Installation of CoolSafe
Make sure that the mains supply is according to the specifications on the type label placed
on the rear panel.
It is important that free air circulation is available at the air inlet and outlet grills. If the
CoolSafe is positioned against a wall, there must be at least 100 mm free space at the rear
of the unit.
The CoolSafe Basic or Pro 95/55-15 and the CoolSafe Basic or Pro 100-9 are both floor
standing units fitted with castors, the front pair being lockable. Before operating the system
insure that the castors are in the locked position.
3.2
Installation of vacuum pump
A two-stage vacuum pump (with 2-5 m
3
/h capacity or greater) must be connected to the CoolSafe
Basic or Pro via the connection on the rear of the CoolSafe Basic or Pro cabinet in order to allow
cryo pumping.
On the floor-standing models, the vacuum pump can be installed on the rear of the CoolSafe on a
shelf support delivered with the equipment. On table models the vacuum pump must be placed near
to the freeze dryer.
LaboGene recommends the VacuuBrand RZ2.5 rotary vane pump for which a variety of protection
accessories, against aggressive materials are available. The vacuum pump outlet/exhaust is fitted
with an oil mist filter as standard.
