4.2.2 Charging level in liquid receiver
The liquid receiver is equipped with 2 sight glasses, one approximately at 30% charging quantity and
one at 80% quantity. The level watch device gives an alarm to the system controller at 20% charging
quantity.

4.2.3 Oil charging procedure
Copeland Large Outdoor OMTE & OLTE condensing units are pre-charged with oil. After
commissioning, the oil level should be checked and topped up if necessary.
As mentioned in chapter 2.6.1 "Qualified refrigerants and oils", Emerson recommends charging with
one of the following oil types:
▪
Emkarate RL 32 3MAF
▪
Mobil EAL Arctic 22 CC
Charging on a system in operation can be done through the Schraeder valve located on the suction
shut-off valve.
For an empty system the service connection port on the oil reservoir outlet can be used
– see
Figure
32 .
Figure 32: Oil charging service ports
The compressors in OMTE-152D and OLTE-82D units are equipped with a TraxOil OM4 oil
management device. The compressors will be switched off in case of insufficient oil level. The TraxOil
will inject an adequate quantity of oil if required. It is important to have a sufficient quantity of oil in
the system to ensure proper functionality of the oil management system.
NOTE: OMTE & OLTE units are equipped with an oil separator. This separator is pre-charged
with 3.8 litres of oil. The oil level in the oil separator sight glass should always be up to top
end.
4.3 Rotation direction of Scroll compressors
Scroll compressors, like several other types of compressors, will only compress in one rotational
direction. Three-phase compressors are protected against wrong rotation field by the unit controller.
