Note:
Whenever a relief valve/safety valve has been activated, we recommend recalibrating it.
This must be carried out by competent personnel only. See also EN 378 and existing national
legislation.

Cooling water system
Warning!
The recirculation water system may contain chemicals or biological contaminants, including le-
gionella, which can be harmful if inhaled or ingested. Water systems should only be operated
with an effective biological treatment programme.

Lubricating oils
Compressor oils include the following oil types:
Code design
Oil types
M
Mineral oil, naphtenic base
A
Synthetic oils based on alkylated aromatics (alkyl-benzene)
AP
Synthetic oils blended from alkyl-benzene and poly-alfa-olefin base stocks
S
Semi synthetic oils (hydro-treated mineral oil on paraffinic base)
PAO
Synthetic oils based on poly-alfa-olefin
POE
Synthetic oils based on polyol esters
PAG
Synthetic oils based on polyalkylene glycols
See the Sabroe oil recommendation for the recommended type of oil.
Warning!
When charging oil, follow the safety instructions given by the oil supplier (MSDS: Material
Safety Data Sheet). Always avoid direct contact with the oil as this may cause skin allergies.
Always use protective equipment, goggles and gloves, when charging oil.
When changing oil on the compressor or draining oil from the vessel of the refrigeration plant,
always collect the used oil in containers marked “waste oil,” and send them to an approved
hazardous waste disposal site. It is not recommended to reuse oil.
2.4.9
Refrigerants
Be very careful when dealing with refrigerants. For safe handling, please refer to the safety/da-
ta sheets delivered by the refrigerant supplier.
Warning!
Be aware that large amounts of leaking (or released) refrigerant entail a risk of asphyxiation. If
in direct contact with leaking liquid refrigerant, there is a high risk of injuries caused by
frostbite.
2.4.10
Purging a refrigeration plant
Purging of air or other non-condensable gases is required in order to keep high system per-
formance and avoid corrosion of the equipment, which could endanger the safety of persons
and equipment.
When purging a refrigeration system, make sure to observe the following:
