3.2.7.1 Initial Charge of Lubricating oil
At initial commissioning or after periodical inspection, the compressor's moving parts such as bearings
and mechanical seals may not be sufficiently lubricated. So, charge the compressor with lubricating oil
according to the following procedure.
1. Thoroughly evacuate the compressor and oil separator (approximately 40 Torr).
2. Open the downstream side valve of the oil filter, and charge 10 liters of lubricating oil from the oil
supply port.
3. Turn the compressor's rotor shaft.
4. Close the downstream side valve of the oil filter.
5. Open the upstream side valve of the oil filter, and charge lubricating oil to the oil separator until it
reaches the specified level.
 Be sure to conduct the initial charge of lubricating oil in such a way that the oil cooler and oil filter
are filled with lubricating oil.
 For details about lubricating oil to be used, refer to Section 4.1 "Lubricating Oil (Refrigerant Oil)"
in this manual.
 Depending on the equipment configuration of your package unit, define the amount of initial
charge of lubricating oil, and make sure to provide users of this product with the information.
3.2.7.2 Additional Charge of Lubricating Oil
Define the procedure of the additional filling of lubricating oil based on the configuration of the package
unit, and make sure to provide users of this product with the information.
3.2.8 Charge of Refrigerant
Depending on the use working fluid and equipment configuration of your package unit, specify the work
procedure that considered safety enough, and conduct the refrigerant filling work accordingly.
In addition, specify the procedure of the additional filling of refrigerant, make sure to provide users of
this product with the information.
3.2.9 Check after Installation
Depending on the package unit to which this product is
installed, formulate the necessary confirmation items and
methods for package unit after installation and conduct them
accordingly before the commissioning. Also, make sure to
record and keep the results of your confirmation.
In addition, in case of i160*, make sure to confirm the following
point. Do not forget it.
 The angle valve (P/N: 554) shown in Figure 3-2
should be always closed during operation.
Confirm that the valve is closed at the check work
after installation before the commissioning.
Note that i125* models don’t have this valve.
