INTRODUCTION
Shown below, you can find the procedure that you must follow to replace compressors.
INSTALLATION INSTRUCTION
Steps to follow:
1)
Remove the damaged compressor and define the reason of the flaw.
2)
Wash the system with a R134a solution or another specific solution.
3)
ERA strongly recommends to use a specific solution for the washing which is also more efficient
from a chemical point of view, After the washing is not recommended to use the removed coolant
from the circuit, because it could be contaminated by the remaining of the old compressor.
4)
If the replaced compressor left impurities, remaining or particles in the AC system, the condenser
should be replaced, otherwise this could produce the break of the compressor.
5)
Complete the installation of the spare parts ( dryer / accumulator filter, expansion valve or orifice
pipe).
