0 = Moisture Indicating Sight Glass -
The sight glass shows if the liquid line has a full line of
liquid or if it has bubbles which shows it’s a liquid/vapor mix. It should not be used to determine
proper charge. The moisture indicator shows if the system is dry or if it has harmful moisture
content.
A = Moisture Indicating Sight Glass + Compressor Isolation Valves –
In addition to the
Moisture Indicating Sight Glass, ball type Compressor Isolation Valves
are mounted on the cooling
circuit discharge and suction lines permitting isolation of the compressor for service or replacement.
The valves are located close to the compressors. The valve works through a quarter turn from open
to closed. Teflon seals and gaskets are used with a nylon cap gasket to prevent accidental loss. This
option reduces the amount of refrigerant that must be recovered during compressor service or
replacement since closing these valves isolates the compressor.
B = Moisture Indicating Sight Glass + Replaceable Core Filter Driers -
In addition to the
Moisture Indicating Sight Glass,
Replaceable Core Filter Driers allow for easy changeout of the
filter-drier element.
C = Moisture Indicating Sight Glass + Replaceable Core Filter Compressor Isolation
Valves
Digit 36 — Water Connection
0 = Grooved Pipe Connection, Standard Header Length
A = Grooved Pipe Connection, Extended Header Length –
To provide additional spacing
beyond the standard ¾” between modules,
t
he Grooved Pipe Connection, Extended Header Length
Kit consists of grooved pipe couplings and spacer pipe to allow for easy installation of water
manifold units.
D = No Header Piping (Heat Exchangers Only) –
When chiller is used in standalone operation
(i.e., single module) an array header is not necessary. It is a cost savings to use the 6” array header
only when needed for array applications or it is desirable to keep field piping to a minimum. Field
piping can be connected to heat exchangers instead of factory provided header.
