Beco BP109C - Intrinsically Safe Component Repair; Cabling Checks; Flammable Refrigerant Detection

Local Air-conditioner / User Manual

C
Note:
The use of silicon sealant may inhibit the
effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated
prior to working on them.
3. Repar to ntrnscally safe components
Do not apply any permanent inductive or capacitance loads to the
circuit without ensuring that this will not exceed the permissible
voltage and current permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked
on while live in the presence of a flammable atmosphere. The test
apparatus shall be at the correct rating. Replace components only
with parts specified by the manufacturer. Other parts may result in
the ignition of refrigerant in the atmosphere from a leak.
4. Cablng
Check that cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
effects. The check shall also take into account the effects of aging
or continual vibration from sources such as compressors or fans.
5. Detecton of flammable refrgerants
Under no circumstances shall potential sources of ignition be used
in the searching for or detection of refrigerant leaks. A halide torch
(or any other detector using a naked flame) shall not be used.
