10 - Maintenance and Spare Parts
10.1 - Safety instructions
All maintenance operations must be carried out strictly by observing the European and National accident prevention regulations. We refer
especially to the accident prevention regulations concerning electrical systems, refrigerators, and manufacturing resources.
Maintenance may be done to air conditioning equipment only by authorized and qualified technicians.
In order to keep all warranties valid, the maintenance must adhere to the manufacturer’s regulations.
DANGER: The work should be done in the system only when it is at standstill. Do this by switching off the air
conditioner at the controller and the main switch. Post a warning sign saying: “DO NOT SWITCH ON.” Electrical
components of device have to be switched off and be checked that they are not under voltage.
Ignoring the safety instructions can be dangerous to persons as well as to the environment.
Soiled parts always cause a loss of performance and for switch or control devices can lead to the break-down of a plant.
10.2 - Spare parts
Only original spare parts made by Vertiv may be used. Using third party material can invalidate the warranty. When making inquiries
always refer to the ”Component List” supplied with the equipment and specify the model number, serial number and, if available, also the
part number.
NOTES:
1) When a faulty component is replaced, follow the relevant manufacturer instructions.
2) When the spare parts must be welded, be careful not to damage the internal parts (gaskets, seals, o-rings, etc.).
10.3 - Maintenance schedule
Monthly, quarterly, biannual and annual checks are to be conducted according to the following guidelines.
All tasks and periods listed here are regulations from the manufacturer and need to be documented in an inspection report.
CAUTION: All these tasks should be carried out only by an authorized and trained technician. We recommend the

10.4 - Air filter check and replacement
It is important to check the state of the air filter every month to maintain a good efficiency of air distribution through the evaporator coil.
CAUTION: Sharp edges, splinters and exposed fasteners can cause personal injury! Only properly trained personnel,
electrically instructed, wearing appropriate safety headgear, gloves, shoes and glasses can carry out this operation!
