Safety Tips
By drilling the walls of the unit or the isothermal cold room, you could damage
the electric wires or the refrigeration piping. Should such action be strictly nec-
essary, great care should be taken to avoid any damage.
Touching turning fans and moving belts can cause irreparable damage or injury.
Be careful with the blades of the condenser and evaporator; their edges are very
sharp.
The refrigeration oil used is a synthetic, mineral-base oil; it can irritate the skin in
case of long contacts or if after coming into contact with oil, the affected areas
are not carefully washed.
Refrigerant
Some special safety warnings need to be reminded concerning the refrigerant.
DO NOT HANDLE THE REFRIGERANT BEFORE READING THE NOTES
BELOW.
If heated, the refrigerant gives off a gas that irritates the respiratory system.
Never heat a closed refrigerating system.
Be careful when servicing the refrigeration circuit. On contact with the air, the
pressurized refrigerant evaporates and it immediately frostbites whatever is in
close contact with it. Should this gas come into contact with the body, below are
some first aid measures:
1. Cover the affected area.
2. Quickly heat the frostbitten area with lukewarm water. AVOID USING HOT
WATER.
3. If there is no water available, wrap up the affected area carefully with a clean
cloth.
4. If the gas comes into contact with the eyes, rinse them immediately with run-
ning water and call an ophthalmologist.
