1 Introduction
This pressure equipment is designed for installation in
refrigeration systems according to the EC Machinery
Directive 2006/42/EC and the Pressure Equipment Dir-
ective 2014/68/EU. They may only be put into operation
if they have been installed in the machines according to
these Assembly/Operating Instructions and if the over-
all system complies with the applicable legal provisions
(applied standards: see Declaration of Conformity).
The pressure equipment has been built in accordance
with state-of-the-art methods and current regulations.
Particular importance was placed on user safety.
Always keep these operations instructions near the re-
frigeration system for the whole lifetime of the pressure
vessel.

3.1 Special notes for CO2 liquid receivers
• Last letter K, PS = 45 bar
• For the usual application of the vessels as liquid re-
ceivers, special corrosion protection measures and
additional insulation are required due to low operat-
ing temperatures.
• The receivers may only be operated in combination
with a pressure relief valve (max. 45 bar). Select and
arrange valves according to the manufacturer's in-
structions.
DANGER
CO2 is an odourless and colourless gas and
cannot be perceived directly in case of emis-
sion!
Lost of consciousness and danger of suffocation
by inhaling higher concentrations!
Avoid CO2 emission and uncontrolled deflating,
particularly in closed rooms!
Aerate closed machine rooms!
Make sure that the safety regulations in accord-
ance with EN378 are complied with!
3.2 System registration
Liquid receivers and oil separators are pressure equip-
ment according to the EU Pressure Equipment Direct-
ive 2014/68/EU. For this reason the entire system must
be registered with the supervisory authority and duly
approved in accordance with the local regulations.
The category for the conformity assessment of each
pressure vessel is listed in the following table.
For the inspection before commissioning and recurring
inspections, national regulations must be considered
(for example the Industrial Safety Regulation BetrSichV
in Germany).
In non-EU countries, local regulations must be com-
plied with.

4 Mounting
4.1 Transporting the pressure vessel
Transport the pressure vessel screwed on a pallet. Lift
it using the eyebolts or the upper fastening brackets if
available.
DANGER
Suspended load!
Do not step under the machine!
4.2 Installation location
For outdoor installation, take suitable measures to pro-
tect the pressure vessel against corrosion (e.g. caused
by seawater or aggressive atmosphere) and low out-
side temperatures. Consultation with BITZER is recom-
mended.

DB-300-910
4.3 Maximum allowable pressure
The whole system must be designed and operated in
order to guarantee that the maximum allowable pres-
sure in the pressure vessel cannot be exceeded.
Pressure relief valves are absolutely necessary if
• it is to be expected that the maximum allowable
pressure will be exceeded due to external heat
sources (e.g. fire), or if
• the entire refrigerant charge of the system is more
than 90% of the vessel volume at 20°C. Vessel
volume means the volume between the valves be-
fore and after a pressure vessel, which can be shut
off during normal operation. In case of vessels in-
stalled in series, it is the volume of all vessels and
the connecting pipe.
In these cases, pressure relief devices should be in-
stalled to direct the refrigerant or the oil towards the
low-pressure side of the system (emission reduction).
Safety switching devices for limiting the pressure
According to the local regulations, safety switching
devices for pressure limiting must be provided.
4.4 Removal clearance for probe
• Option
• Liquid receivers FS202 .. FS5502
If the probe for infinite liquid level monitoring is moun-
ted or should be retrofitted, the liquid receiver must be
mounted such that the probe can be taken out upwards
(see figure 1, page 10).

4.6 Delivery condition
The pressure vessel is sealed in the delivery condition
and filled with inert gas. The inert gas overpressure is
0.2 .. 0.5 bar. All Rotalock and flange connections are
closed by blanking plates. These plates must be re-
moved before commissioning.
4.7 Connecting the pipelines
The pipe connections are suitable for pipes in all com-
mon dimensions in millimetres and inches. Brazed con-
nections have stepped diameters. The pipe will im-
merge more or less depending on its dimensions. If not
required the end with the largest diameter can be cut-
off.
DANGER
Risk of bursting the pressure device due to
mechanical stress.
Serious injuries are possible.
Connect the pipeline to the pressure unit without
stress!
First relieve the excess pressure from the pressure
vessel: Open the connections carefully.
WARNING
The pressure equipment is under pressure!
Serious injuries are possible!
Depressurise the pressure equipment!
Wear safety goggles!
Remove shut-off valves and/or solder connections.
!
!
NOTICE
Potential chemical reactions due to air penetra-
tion!
Install the open pressure vessel immediately in
the system.
Reseal the pressure vessel during installation breaks.
!
!
NOTICE
Do not overheat the shut-off valves!
Cool the valve body during and after the brazing
operation.
Maximum brazing temperature 700°C!
When brazing or welding, rinse the corresponding con-
ductive parts with inert gas.

DB-300-912
Clean pipes
Use only pipelines and system components which are
• clean and dry inside (free from slag, metal filings,
rust and phosphate coatings) and
• which are delivered with an air-tight seal.
4.7.1 Mounting the pressure relief valve
Internal thread 3/8-18 NPTF: Screw in the pressure re-
lief valve.
External thread 1 1/4-12 UNF: Screw the pressure re-
lief valve into the adaptor. Then fasten the adaptor at
the pressure vessel with the union nut.
Available adaptors see figure 3, page 12.

4.8 Oil separator
Install oil heater(s) in the oil separator and connect
them according to the schematic wiring diagram (see
also SH-100, SH-500). During long shut-off periods, the
oil heater prevents excessive refrigerant concentration
in the oil and therefore reduction of viscosity. It must be
on when the compressor is at standstill.
Insulate the oil separator:
• for operation at low ambient temperatures or
• with high temperatures on the high-pressure side
during standstill (e.g. heat pumps).
The oil level switch and the oil thermostat are sup-
plied separately and must be mounted on site.
Mounting position see figure 4, page 13.
