IMPORTANT NOTICE
All Baltic units are compliant with the PED directive 97-23-
CE.
The following note must be followed carefully.
IMPORTANT NOTICE
All work on the unit must be carried out by a qualified and authorised employee.
Non-compliance with the following instructions may result in injury or serious accidents.
Work on the unit:
• The unit shall be isolated from the electrical supply by disconnection and locking using the
main isolating switch.
• Workers shall wear the appropriate personal protective equipment (helmet, gloves,
glasses, etc.).
Work on the electrical system:
• Work on electric components shall be performed with the power off (see below) by
employees having valid electrical qualification and authorisation.
Work on the refrigerating circuit(s):
• Monitoring of the pressures, draining and filling of the system under pressure shall be
carried out using connections provided for this purpose and suitable equipment.
• To prevent the risk of explosion due to spraying of coolant and oil, the relevant circuit shall
be drained and at zero pressure before any disassembly or unbrazing of the refrigerating
parts takes place.
• There is a residual risk of pressure build-up by degassing the oil or by heating the
exchangers after the circuit has been drained. Zero pressure shall be maintained by
venting the drain connection to the atmosphere on the low pressure side.
• The brazing shall be carried out by a qualified brazer. The brazing shall comply with the
standard NF EN1044 (minimum 30% silver).
Replacing components:
• In order to maintain CE marking compliance, replacement of components shall be carried
out using spare parts, or using parts approved by Lennox.
• Only the coolant shown on the manufacturer's nameplate shall be used, to the exclusion of
all other products (mix of coolants, hydrocarbons, etc.).
CAUTION:
In the event of fire, refrigerating circuits can cause an explosion and spray coolant gas and oil.
