To ensure that your WS system remains at its optimal performance levels, we recommend that you make a plan to carry out regular maintenance on your system, this should be carried out at the very least once a month, and should include the following actions: Removal & cleaning of all dust filters With dust filters removed, if the radiator is exposed then dust this off with a paint brush/ compressed air With dust filters removed, if the cooling fans are exposed then hold these in place and proceed to dust these off with a paint brush/ compressed air. Determine which of the below diagrams refers directly to your specific case, based on its appearance: Inadequate maintenance of your system can lead to a build-up of dust and debris over time. This can dramatically reduce the effective air flow and cooling required to maintain quiet and stable operation of your system. It can also impede optimal performance and reduce component life. In the unfortunate event that your system develops a fault and our engineers assess and diagnose either remotely or at our support lab, that the fault is determined to be as a result of such inadequate maintenance, then subject to clause 8.4.3 as laid out in your terms & conditions, WS reserves the right to apply a charge for the repair. This will be communicated before any such work is carried out and applies throughout the contracted warranty period. “8.4.3 The Products have not been altered, modified or subject to misuse, incorrect installation/maintenance, neglect, accident or damage by excessive current or used with incompatible parts.” In light of the above, WS advises that the steps towards cleaning your filters as shown in the above diagrams, be implemented into a regular maintenance plan. We advise that these actions are carried out on average at the very least once per month with heavy usage systems, and should be adjusted according to environmental conditions such as naturally dusty working environments. Following the advice given above, this will greatly reduce chances of system downtime, component degradation, and any potential drop in system performance as a result of overheating. WS also offer a chargeable service/maintenance check on all of our systems.
