GENERAL SATEFY NOTICES
WARNING:
Use ONLY Polyol Ester based refrigeration compressor oil in units. DO NOT mix Polyol Ester and standard
synthetic compressor oils. Keep Polyol Ester compressor oil in tightly sealed containers. If Polyol Ester oil becomes
contaminated with moisture or standard oils, dispose of properly—DO NOT USE!
WARNING:
When servicing Zanotti units, use only those service tools certified for and dedicated to refrigerant and
Polyol Ester compressor oils. Residual non-HFC refrigerants or oils will contaminate R- 404A and R-134A systems.
1.
Always wear goggles or safety glasses. Refrigerant liquid, refrigeration oil, and battery acid can
permanently damage the eyes (see First Aid under Refrigeration Oil).
2.
Never operate the unit with the compressor discharge valve closed.
3.
Keep your hands, clothing and tools clear of the fans and belts when the unit is running. This
should also be considered when opening and closing the compressor service valves.
4.
Make sure manifold gauge hoses are in good condition. Never let them come in contact with a
belt, fan motor pulley, or any hot surface.
5.
Never apply heat to a sealed refrigeration system.
6.
Fluorocarbon refrigerants including r134a and r404a, in the presence of an open flame or
electrical short, produce PHOSGENE. A toxic gas that are severe respiratory irritants
capable of
causing death.
7.
Make sure all mounting bolts are tight and are of correct length for their application.
8.
Use extreme caution when drilling holes in the unit. The holes may weaken structural
components, and holes drilled into electrical wiring can cause fire or explosion.
9.
Use caution when working around exposed coil fins. The fins can cause painful lacerations.
10.
Use caution when working with a refrigerant or refrigeration system in any closed or confined
area with a limited air supply (for example, a vehicle box or garage). Refrigerant tends to displace
air and can cause oxygen depletion
resulting in suffocation and possible death
.
11.
When performing any check of the system make sure the unit is turned off and the battery power
supply is disconnected.
12.
Be sure unit is turned off before working on motors, controllers, solenoid valves and electrical
components. Problems with the system should be diagnosed, and any necessary repairs
performed, by qualified service personnel only.
13.
Do not bypass any electrical safety devices, for instance bridging an overload or using any sort of
jumper wires.
14.
Do not wear any electrically conducting materials. I.E. jewelry, rings, watches, necklaces, etc.
15.
Secure any loose objects on self. Such as hair, jacket laces, shoe laces, etc...
Refrigerant
Although fluorocarbon refrigerants are classified as safe refrigerants, certain precautions must be observed when
handling them or servicing a unit in which they are used. When exposed to the atmosphere from the liquid state,
fluorocarbon refrigerants evaporate rapidly, freezing anything they contact.
In the event of frost bite, the objectives of First Aid is to protect the frozen area from further injury, to warm the
affected area rapidly and to maintain respiration.
