Recommended Disposal
4.2
When the product reaches the end of its service life, its primary components can be recycled.
Before the materials can be removed, the product must be disassembled. Product parts and materials can be dismantled and separated.
Generally, all metals, such as steel, aluminum, copper and its alloys, and precious metals can be recycled as material. Plastics, rubber, and
cardboard can be used in energy recovery. Printed circuit boards and large electrolytic capacitors with a diameter of over 2.5 cm (1 in)
need further treatment according to IEC 62635 guidelines. To ease recycling, plastic parts are marked with an appropriate identification
code.
Contact your local office for further information on environmental aspects and recycling instructions for professional recyclers. End-of-
life treatment must follow international and local regulations.
All products are designed and manufactured in accordance with company guidelines on prohibited and restricted substances. A list of
these substances is available at www.danfoss.com.
This symbol on the product indicates that it must not be disposed of as household waste. Do not dispose of equipment
containing electrical components together with domestic waste.
It must be handed over to the applicable take-back scheme for the recycling of electrical and electronic equipment.
• Dispose of the product through channels provided for this purpose.
• Comply with all local and currently applicable laws and regulations.

Preventive maintenance actions
(2)
Conductive dust and aggressive gases, such as sulphide, chloride,
and salt mist, can damage the electrical and mechanical compo-
nents. Air filters do not remove airborne corrosive chemicals. Act
based on findings.
The expected life time of the capacitor is determined based on
load and the temperature of the environment. Replace parts ac-
cording to the service schedule. For applications with heavy loads
or demanding environments, replace the capacitors every 12
years. In a typical environment, within the specifications of the fil-
ter, replace every 15 years. Only trained service personnel are al-
lowed to perform this action.
Visually inspect the printed circuit boards for signs of damage or
degrading due to aging, corrosive environments, dust, or environ-
ments with high temperatures. Only trained service personnel are
allowed to perform the inspection and service action.
Inspect the insulators for signs of degradation due to high temper-
ature and aging. Replacement is based on findings. Only trained
service personnel are allowed to perform this action.
Inspect the condition and operational status of all cooling fans.
With the power off, the fan axis should feel tight, and spinning the
fan with a finger, the rotation should be almost silent and not have
abnormal rotation resistance. When in RUN mode, fan vibration,
excessive or strange noise is a sign of the bearings wearing, and
the fan must be replaced.
