Safety
• When the cause of the shutdown has been removed, the motor may restart. This can be
dangerous for machines and installations, and it is therefore important that the user takes
adequate precautions against restarting if the motor makes an unscheduled stop.
• System maintenance must always be carried out by personnel who have the necessary
training and experience.
2.3.7 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, al-
ways collect the used oil in containers marked “waste oil,” and send them to an approved hazard-
ous waste disposal site. It is not recommended to reuse oil.
2.3.8 Refrigerants
Be very careful when dealing with refrigerants. For safe handling, please refer to the safety/data
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.
2.3.9 Purging of DualPAC
Purging of air or other non-condensable gases is required in order to keep high system perform-
ance and avoid corrosion of the equipment which could endanger the safety of persons and
equipment.
When purging the DualPAC, make sure to observe the following:
• Refrigerants must not be released into the atmosphere.
• When purging an R717 system, use an approved air purger. The purged air must pass
through an open container or water for any remaining R717 to be absorbed. The water
mixture must be sent to an authorised incineration plant.
• Halocarbon refrigerants (CFC, HCFC and HFC) cannot be absorbed by water. An approved
air purger must be fitted to the system. This must be checked regularly by use of a leak
detector. All precautionary measures practicable must be taken to prevent and minimise
leakage of refrigerant from refrigeration and air conditioning systems to the atmosphere.
