This unit is not designed or intended to operate when
contaminated with silicone. Lubricants, greases or other items
containing silicone should not be used on this unit.
DRYER MAINTENANCE (DRYER OPTION)
WARNING
The dryer’s refrigeration system operates in a pressurised
shutdown mode. If the compressor stops, the system will
contain high pressure refrigerant. The refrigeration system
must only be opened by a qualified technician certified in
handling refrigerants. Never adjust thermal expansion valve. It
has been factory set.
Oil level checking procedure
The oil level should be checked regularly. An oil level sight glass is
located at the bottom of the refrigeration compressor and while the
machine is running on load, oil should always be visible in the sight
glass. The normal position is half way.
Adding oil
The refrigeration circuit is hermetically sealed so adding oil should
never be necessary unless the system is leaking or has been pumped
down or recharged.
If adding oil is necessary, do the following.
Run the dryer for a minimum of 2 minutes, the oil level should be
visible in the sight glass. If not, slowly add the proper oil, using the
appropriate pump, to the Schrader
t
valve on the suction connector
of the compressor. Continue until the oil level is visible in the sight
glass with the compressor running.
CAUTION
Do not mix oil types. Use only oil specified by IR
