HC R290 Refrigerant Lssues
Basics
HC R-290 (propane) is an odourless and colourless gas of the group of hydrocarbons.
HC R-290 is heavier than air and at high concentrations can cause
narcotic effects and eventually asphyxiation.
R-290 is highly ammable within the range of 2,1% and 9,5% by volume, or 38
g/m3 to 170 g/m3 in air. The auto-ignition temperature is about 470°C.
Since R-290 is an odourless and colourless gas, it is difcult to perceive that it is
present (as with most other refrigerants).
Propane is often used as a fuel such as for heating or barbecues. However, for
use on refrigeration systems, fuel-grade propane is not suitable since it contains
high levels of impurities, which would damage the refrigeration system and may
not provide the desired refrigerating capacity or efciency.
Please notice that the unit is filled with propane. Details to this refrigerant are found in chapter “refrigerant”. Propane is highly
ammable and leads to explosion under certain conditions. Inappropriate treatment of the unit involves the risk of severe damages
of people and material.
The structural formula of HC R-290 (propane)
HC R-290 refrig-
erant has a high
grade of purity.

Flammability
Safety Data
Hazard Identication
Three components are needed simultaneously for causing re:
For ignition, the concentration of HC in air has to be between the lower and upper
ammable limits. If the concentration is below the lower ammability limit (LFL) of about
2% by volume in air, there is not enough HC for combustion. If the concentration is
above the upper ammability limit (UFL) of about 10% there is insufcient oxygen for
combustion.
Possible ignition sources are:
1. A flame, for example from brazing torch, halide torch leak lamp, match or
lighter, cigarette
2. A spark from an electrical component
3. Static electricity
4. Hot surfaces
· Extremely ammable (F+).
· Readily forms an explosive air-vapour mixture at ambient temperatures.
· Vapour is heavier than air and may travel to remote sources of ignition (e.g.
along drainage systems, into basements etc).
· Liquid releases generate large volumes of ammable vapour (approx 250:1)
· Cold burns (frostbite) will result from skin / eye contact with liquid.
· Liquid release or vapour pressure jets present a risk of serious damage to
the eyes.
· Abuse involving inhalation of high concentrations of vapour, even for short
periods, which can produce unconsciousness or may prove fatal. Inhalation
may cause irritation to the nose and throat, headache, nausea, vomiting,
dizziness and drowsiness. In poorly ventilated areas unconsciousness or
asphyxiation may result.

Note: vapour may collectin conned spaces.
Further actions:
· Stop release
· Use dry powder or carbon dioxide extinguishers
· Cool containers exposed to re by using water / mist spray.
Due to the flammability of R-290 and the risk of fire or explosion during servicing,
special safety rules must be followed during operation. In order to avoid damage for
people and property, particular requirements are listed hereafter.
Before servicing the unit, the surrounding area were the work will be done must be
clear of safety hazards to ensure safe working. Nevertheless it is required to carry out
a risk assessment in order to minimise the risk of ignition of R-290.
1. Any employees and other present persons must be informed about the service and the way the service is done, rst.
2. It is recommended to isolate the working environment in order to keep out any unauthorised personnel.
3. It is useful to set up signs such as „no smoking“ or „access denied“.
4. It is prohibited to store any combustible goods within the working environment.
5. Within two (2) metres radius, ignition sources are not allowed in the working area.
6. Fire extinguisher (dry powder) must be easily accessible at any time.
7. During service work, proper ventilation of the environment must be ensured.
Accidental Release Measures
Accidental Release Measures
The following safety measures must be followed:

10 Technical Information
Service Manual
Sign plate to protect and mark the working area.
Appropriate detectors, suitable for hydrocarbons, must be available and operational all the time. Appropriate tools and
appliances must be available and ready for operation.
Any employees need to be instructed extensively about the safety measures and the possible safety hazard.
Before starting service work on the refrigerant circuit, the existing refrigerant must
be removed. When carrying out removal of the refrigerant, the following must be
considered:
· The recovery cylinder must be permitted for the use of R-290 (especially regarding the
pressure and the compatibility of the connectors and the valves).
· The recovery machine must be suitable for operation with R-290. Importantly, the
recovery machine must not itself be an ignition source.
· The lling of the recovery cylinder should be monitored closely by controlling the weight.
It is recommended to place and then to leave the cylinder on a digital scale. Pay attention
to not overfilling the cylinder. The cylinder is only allowed to be filled up to 80% of its
complete volume by liquid refrigerant.
· The pressure must be controlled in order to ensure that the permissible pressure of the
cylinder is not exceeded at any time.
· After filling, the cylinder must be marked with the mass and the type of refrigerant
recovered.
· The recovery machine should be operated until the pressure reduces to 0,3 bar
absolute pressure. R-290 is soluble to oil. This may lead to a rise of pressure because the
refrigerant vaporises from oil. It may be necessary to operate the recovery machine for a
second or even a third time.
· Small amounts of R-290 can be vented in safe manner to the environment.
· Remaining amounts of HC absorbed by the oil can be extracted from the system using
a vacuum pump in combination with an exhaust vent hose.
· A second “two way excess” recovery cylinder can be used in serial connection to act as
an oil-separator.
· After the systems‘ pump out, the system should be ushed with oxygenfree
dry nitrogen (OFDN) in order to ensure no ammable gas are inside
the system.

· Removing the refrigerant from the system in order to avoid an uncontrolled
discharge.
· Examine the leak source, determining the reason for the leak and carry out the
proper course of action
· Repair properly (NO „temporary repairing”)
· Based on the results of the systems’ examination, suitable measures need to be
identied in order to avoid a recurrent appearance of the leak.
· Before embarking on the repair, ensure that the refrigerant has been removed
and the system ushed with OFDN, especially if brazing is to take place
· After each intervention into a refrigeration system (repairing leaks, replacing
components, brazing) the system must be subject to a leak test and following
strength test of the system.

While servicing the unit it is recommended for the whole period of work — before,during
and after — to monitor the gas concentration in the air within the work environment. By
monitoring the air within the work environment the danger of a possible formation of
ammable atmosphere can be detected early.
Doing the monitoring, ensure that the gas detectors are suitable for hydrocarbon detection.
Never use open re or a device with an ignition source for the detection of gas or for leak
detection.
Gas Detection
The HC leak de-
tector is indeed
a PPE device!

12 Technical Information
Service Manual
Before operation of the gas detector the instruction manual must be read carefully.
In case of any questions refer to the detector manufacturer. Furthermore ensure the
detector is correctly calibrated. Instructions for calibration can be found in the instruction
manual of the detector or upon request from the manufacturer.
A possible re-calibration must be done within an area which is free of refrigerants.
In case of a positive detection by the detector any work must be stopped immediately.
Any open ames or ignition sources must be extinguished or removed. In addition to a
suitable and approved HC gas detectors, portable gas detectors can be used.
Such a detector can be clipped to clothing or placed on the floor within the working
area. It should be switched on for the duration of the work, and set to alarm at 15% of
the lower ammability level (LFL), to warn that ammable concentration may be nearby.
In this way, technicians can be alerted whenever an inadvertent release of ammable
refrigerant occurs, and can immediately act upon the relevant emergency procedures.
Portable HC Gas Detector
R-290 is available in a large variety of different cylinders which are to be distinguished
whether they are rellable or not. Most rellable cylinders are equipped with pressure relief
valves, often with own special construction of valves in order to distinguish them from the
cylinders of different refrigerants.
Often special legal requirements about the handling of ammable refrigerants exist in the
different countries. These requirements must be studied and adhered to. Principally the
following regulations in dealing with R-290 cylinders apply:
1. Do not remove or destroy ofcial stickers of the cylinder
2. Close the cylinder with a cap any time the cylinder is not used
3. Never expose the cylinder to direct heat
4. Do not repair or modify the cylinder or the cylinders‘ connections
5. Only use suitable equipment for transportation of the cylinder, even for short distances.
Never roll the cylinder across the ground.
6. Take appropriate measures in order to prevent impurities, water or oil from entering the
cylinder.
7. Should it be necessary to warm the cylinder, only use warm water or air which temperature
must not exceed 40 °C (104 °F). O pen ames or radiant heaters are not allowed at any
time.
Cylinder Handling

Service Manual
8. Weigh the cylinder and compare it against the tare weight (normally stamped on the
cylinder) in order to make sure that it is empty. Pressure control is no secure method to nd
out if and how much refrigerant there is inside the cylinder.
9. For accurate charging, use a set of reliable scales with appropriate resolution (depending
on the size of system charged with refrigerant) and use the smallest size of cylinder
available.
10. For recovery of R-290, only use cylinders which are allowed to be lled with R-290.
11. Make sure that safety inspections are still valid (i.e. within date), specically with regards
to safety test certication.
12. For refillable recovery cylinders keep in mind that with recovered amounts of HC
refrigerant, oil will always be present specific amounts may remain in the cylinder after
emptying.

Always use the
smallest cylin-
der possible and
relay on appro-
priate accurate
and sensitive
scales
The storage of R-290 cylinders is controlled by regulations. These regulations take priority
over the present guidelines. Typically, such rules imply the following:
1. Cylinders should be stored in a separate area, preferably outside, otherwise in a dry, well
ventilated place far away from any ignition source.
2. Admission to storage area must only be given to authorised personnel only. Storage areas
must be labelled with “no smoking” and “no naked ames” sign.
3. Storage areas should be at ground level and never in the basement.
4. Access should be easy – exclude any obstacles.
5. Cylinders should be stored and operated only in an upright position.
6. Choose appropriate measures to prevent static charges
7. Please remember that the maximum quantity of stored refrigerant sometimes might be
regulated by national regulations.
Basically the following must be regarded concerning the transport of R290 cylinders:
1. During the transportation of R290 always carry along printed information about the
refrigerant. In case of emergency these information must be easy accessible. There
are often different demands to the transporters carrying a great quantity of gas. Inform
yourself before the scheduled transport.
2. Make yourself familiar with the risks of the refrigerant and the emergency measures
in case of accident or emergency.
3. Always carry a re extinguisher during transportation with you. It should be a dry
powder re extinguisher with a capacity at least of 2 kg. Make sure that the driver is
experienced in re extinguisher operation.
4. Cylinders must be transported in an upright position and be tightly secured.
5. Make sure of a proper ventilation inside the van even though it might request a
change in the vans‘ body construction.
6. Place the security advise „ammable gas“ upon the rear side of the van.
7. Smoking or open re is strictly forbidden inside the van.
8. Do not leave cylinders in a locked van without surveillance longer than necessary.
The transport of cylinders is controlled by laws in most countries. These laws must always be regarded first before the
mentioned guidelines here. In many cases information about regulations for the transport of cylinders could be given by the
dealer of the refrigerant.
