Installing New Components
Comments
1
Remove old compressor, drier and any other
defective component.
If the compressor is removed, seal the
suction and discharged tubes to prevent a
spill.
2
Install new FPG approved spare parts.
A new dryer must be fitted if the compressor
is replaced.
3
If the two access line tubes are not at least
30cm long, add more tube with brazed
pinched-off ends. Reinstall tap valves.
Access tubing lines may need to be braced
to prevent bending over.
4
Purge with Nitrogen again at 70 to 140 hPa
while brazing. Wrap drier with wet rag when
brazing.
5
Fill the system with Nitrogen to 1000 kPa and
check for leaks.
6
Release Nitrogen and pull a vacuum on the
system to 250 microns or less. Turn off the
vacuum and confirm that it holds the vacuum.
7
If vacuum holds, the system can now be
charged.
Propane labelled
‘R-290 Refrigerant’ must be
used.
DO NOT USE BBQ PROPANE
.
8
Purge the charging hoses and ready your
gauge set and hoses so they will not move
during the charging process.
9
Check the cabinet Serial Number label for the
required charge.
10
Use the ball valves installed on your hose to
meter in the charge.
Because the charge is small, take care and
be precise.
11
Charge the circuit. (preferred method of
charging is to charge liquid into liquid line).
12
If new starting components have been fitted,
check electrical connections and install all
terminal covers.
FPG compressor start components are
designed for use with HC refrigerants. Do not
use non-FPG approved spare parts.
13
Start the system and check operation. Do a
final check for leaks
