12) Install the new Drier.
13) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.
14) Evacuate the system, and charge it with refrigerant. See the Nameplate for the required
refrigerant charge and type.
15) Connect the Terminals to the Compressor, and replace the Terminal Cover in its correct
position.
16) Replace the panels in their correct position, and turn on the power supply.
4. REMOVAL AND REPLACEMENT OF DRIER - EXCEPT F-2000MLH/-C
IMPORTANT
Always install a new Drier every time the sealed refrigeration system is
opened. Do not replace the Drier until after all other repair or replacements
have been made.
1) Turn off the power supply, and remove the panels.
2) Recover the refrigerant and store it in an approved container, if required by an
applicable law.
3) Remove the Drier using brazing equipment.
4) Install the new Drier with the arrow on the Drier in the direction of the refrigerant flow.
Use nitrogen gas at the pressure of 3 - 4 PSIG when brazing the tubings.
5) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.
6) Evacuate the system, and charge it with refrigerant. For the water-cooled models, see
the Nameplate for the required refrigerant charge and type. For the remote air-cooled
models, see the label on the Control Box.
7) Replace the panels in their correct position, and turn on the power supply.
