Instructions
2 – Handling and storage
When the condensing unit is hoisted with ropes for delivery, take care to maintain the centre of gravity. It could drop off if the stability is lost.
After completing the wiring work, test with a DC 500 V insulation resistance meter between terminals of electric part and ground, and confirm it
detects 1 MΩ or more. However, do not measure the insulation resistance at the electronic circuit (DC circuit).
High voltage is retained for a while (about 1 minute) owing to the residual charge after turning off the power supply of condensing unit. Do not
touch electric parts till the LED on the inverter PCB extinguishes, because it is dangerous.
Delivery
• Determine the delivery route, and deliver the unit to the installation place without removing the packing.
• When hoisting the unit, use a pair of ropes and cushions to protect sections chafed by the ropes.
NOTE:
• Make sure to pass the ropes through square holes on the fixing legs of condensing unit.
• Protect surfaces of the condensing unit where the ropes are applied with wear plates or cushions.

• It is recommended not to open the packaging before the unit is at the final place for installation.
• Handle the unit with care. The packaging allows for the use of a forklift or pallet jack. Use appropriate and safe lifting equipment.
• Store and transport the unit in an upright position.
• Store the unit between -35°C and 50°C.
• Don't expose the packaging to rain or corrosive atmosphere.
• After unpacking, check that the unit is complete and undamaged.
3 – Installation precautions
Do not braze as long the condensing unit is under pressure.
Never place the unit in a flammable atmosphere
Place the unit in such a way that it is not blocking or hindering walking areas, doors, windows or similar.
• Ensure adequate space around the unit for air circulation and to open panels. Refer to picture below for minimal values of distance to walls.
• Avoid installing the unit in locations which are daily exposed to direct sunshine for longer periods.
• Avoid installing the unit in aggressive and dusty environments.
• Ensure a foundation with horizontal surface (less than 3° slope), strong and stable enough to carry the entire unit weight and to eliminate vibrations and interference.
• The unit ambient temperature may not exceed 50 °C during off-cycle.
• Ensure that the power supply corresponds to the unit characteristics (see nameplate).
• Use clean and dehydrated refrigeration-grade copper tubes and silver alloy
brazing material.
• Use clean and dehydrated system components.
• In Optyma™ iCO2 condensing unit has suction and liquid service valve with
schrader port for field service operation
• Confirm that the strength and levelness of foundation can prevent vibration
and noise.
• Fix the unit securely so that it will not be toppled by earthquake, or sudden
gust.
