Hazards with incorrectly ﬁ lled systems

Overﬁ lling

Overﬁ lling the system inevitably results in a high condensing pressure and loss of cooling capacity. The high

pressure switch can be triggered as a result.

Underﬁ lling

A system which is insufﬁ ciently ﬁ lled results in the following:

Output reduction due to evaporation temperatures which are too low, and triggering of the low pressure

switch. Excessive overheating temperature which can result in compressor damage.

Note:

Recommended superheating:

12 - 18°F (7 - 10 K)

Recommended subcooling:

> 3.6°F (2 K)
