3. Remove the outlet pipe together with the nipple.
4. Fit the nipple to the new outlet pipe and tighten. Use only PTFE tape.
5. Fit the plastic insert in place as indicated on the drawing and assemble the outlet pipe with a
maximum torque of 5 Nm (3.7 lbf.ft). Do not end turning counterclockwise in order to avoid leaks.
Use only PTFE tape.
Warning:
If the outlet pipe is tightened too hard, the thread of the element can get damaged or the
insert can break, resulting in overheating of the compressor element!
6. Fasten coupling (3) while holding nipple (2) with a wrench.
The outlet pipe of the 5.5 kW element does not contain an insert and does not require any maintenance. In
case of disassembly, please apply the same torque and procedure as described above.
6.10 Refrigerant dryer maintenance
Safety precautions
The dryer circuit contains refrigerant.
When handling refrigerant, all applicable
must be observed. Specifically be aware of following points:
• Contact of liquid refrigerant with the skin can cause freezing. Wear special gloves. If contacted with
the skin, the skin should be rinsed with water. On no account may clothing be removed.
• Fluid refrigerant can also cause freezing of the eyes. Wear safety glasses.
• Avoid inhalation of refrigerant vapors. Check that the working area is adequately ventilated.
Be aware that internal components of the dryer such as the pipes can reach a temperature of up to 110˚C
(230˚F). Therefore, wait until the dryer has cooled down before removing the side panels.
Before starting any maintenance or repair work, switch off the voltage and close the air outlet valve.
