East Tower Chillers Issue

Dear Residents, One of the 2 chillers that serves the East Tower is out of service. An engineer has attended and we are awaiting a part to be delivered. One chiller could usually service the building but due the current high temperatures and increased use the temperature of the water getting to the cooling may not be as cold as usual during peak times(18.00-06.00). As a short term measure during these high temperatures can I ask that you only use the cooling in the rooms you are in and keep your windows closed if trying to cool the room. Thank you for your assistance and apologies for the inconvenience. Kind regards Barry
