The following table, shows which are the routine maintenance visits, which are the specific maintenance visits, and when
these visits must be performed. Depending on the level of maintenance contract chosen, the routine maintenance visits
can be performed by customer and under customer’s responsibility (requiring that the customer is qualified to perform
such work in the local jurisdiction. Socomec requires the customer to provide a maintenance report to Socomec after each
routine maintenance operation). The specific maintenance visits must always be performed by Socomec or an authorized
third party.
The following inspections should be performed at the recommended intervals given in the table below:
Table of Preventative Maintenance
Schedule Inspections/Procedure
Yearly * • Check and keep the site clear around the unit removing any foreign material that could block the intake grills.
• Check all the ventilation grills are free from dirt and debris.
• Check all the C-Cab filters for any dirt and debris accumulation; clean, wash or replace as required
following the instructions below; the replacement must be done at least once per year.
• Check the SPD functionality in the C-Cab following guides and procedures (See details below). If
defective, must be replaced.
• Clean the pollen from the cabinet if needed during the pollen season to prevent the mesh from being
blocked.
• If there are fluid leaks, or other indication that fluid levels in B-Cabs are low, then ‘Topping up the cooling
system’ may be required (This is to be done by trained personnel only).
• To ensure the free circulation of air in the B-Cab, clean the system regularly as required. Especially for
dusty application scenarios, it is important to clean the air inlet and outlet of the fans. Check and clean the
drain on the floor drain when necessary, using a vacuum cleaner (usage of air-compressor is forbidden).
• Check in all the B-Cabs for the operation of the temperature and smoke sensors as indicated by the red
LED flashing every few seconds.
• Clean the dust on the B-Cabs condensers.
• Inspect signs of external corrosion and use a suitable paint to mitigate the spread of rust. Check for any
wire distortions or colour change. Contact Socomec for additional details.
*Note: The optimal inspection frequency will depend on the operating environment; the minimum recommended inspection frequency is
yearly for clean dry locations, but it is also recommended that there should be monthly inspections for the first quarter to establish an optimal
inspection frequency for the specific site. More frequent inspections may be required for adverse environmental conditions (e.g., Dust, airborne
contaminants, chemical fumes, etc.).
During maintenance visits at the
end of years 3, 5 and 7
• Replace the UPS that is inside the SUNSYS C-Cab L.
Every five years
(by Socomec or trained service
technician only)
Note: The system is completely
powered off for this inspection
• Check for signs of discoloration on all electrical power terminals which is indicative of overheating, if so
clean and re-torque terminals.
• Re-torque all connections including the AC & DC power connections.
• Inspect signs of corrosion and use appropriate paint to mitigate the spread of rust wherever observed.
B-Cab:
• Drain the coolant following the procedure and replace with fresh automotive grade antifreeze (50% Glycol).
• Replace the desiccant in the condenser.
C-Cab:
• Replace the UPS that is inside the SUNSYS C-Cab L.
• Replace the fans (modules and cabinets).
• Replace the extractor.
• Replace the Humidity/Temperature PCB.
• Replace the hygrostat.
• Replace the DC capacitors PCB.
• Replace the AC capacitors PCB.
• Replace the 230Vac/24V DC Power Supply inside Automation Box.
