The device involves cooling gas and transporting procedures should be applied by complying with all
conditions of local regulations. In case of gas leakage, gas accumulation inside closed areas causes a high
risk. Gas may lead to suffocation by replacing oxygen (in case it is inhaled for a long period or it is exposed
of, it causes irritation on skin and at eyes, irregular heartbeat, loss of consciousness and even death) or
explosions.
Equipments on cooling circuits are must be checked if they operate right or not.
Global warming potential of R-410A gas in use is (GWP):1975. According to European or local laws,
periodical maintenance and controls need to be carried out for cooling gas leakages. These maintenance and
controls should be performed according to national laws.
NF E29-795 standard regulating the use and collection of halogenated hydrocarbons should absolutely be
known about.
Conditions defined for refrigerant charge should be considered.
The device should have R-410A base and an operation pressure of ~40 bar. While working on the cooling
circuit, special protection equipments should absolutely be used.
Whether there is any bubble formation at the liquid line should be checked from the sight glass to see that the
gas charge is enough, bubble formation shows that gas charge isn’t enough.
Don’t step on refrigerant lines, equipments may break or crack when exposed to load. This situation may lead
to injuries.
When 410A gas or steam causes irritation when touches the eye and/or skin. Therefore, exposure to this gas
should be abstained from.
Hot pipe line, compressor outlet and electric heater are structures with high thermal hazard. These hazards
should be considered.
Caution! If cooling gas contacts with flame, it generates poisonous gas.
Due to electromagnetic effects, the device shouldn’t be operated near sensitive devices. People with cardiac
pacemakers should be cautious about that.
Room-type combines heat or humidity meter should be mounted minimum at 1.5 m.
The device should be taken into pre-controls before commissioning.
In a cooling system working right, extra heating level should be between 4-10 ºC.
Power used by compressor should be measured by the contactor on the panel and checked if the given values
are exceeded.
Operation status of high pressure prosestat should be checked.
Operation status of low pressure sensor should be checked.
While cleaning the device, it shouldn’t be passed over that wrong applications may cause unwanted damage
on the device and/ or operator. Disposed as to solid waste procedure.
Compressed air should be used for fan cleaning, if possible. Air shouldn’t involve possible lubricant particles.
