Normal Operating Range Minimum temperature ... 0 °C (32 °F) Maximum temperature ... 40 °C (104 °F)Range of Humidity Minimum Humidity "Non-condensing" ... 5% Maximum Humidity "Non-condensing" ... 95%The vacuum pump has the following specifications for short term storage:Short Term Temperature Range Minimum temperature ... −25 °C (−13 °F) Maximum temperature ... 70 °C (158 °F)Short Term Range of Humidity Minimum Humidity "Non-condensing" ... 65% Maximum Humidity "Non-condensing" ... 95%Short Term Storage - Short Term defines the storage period of two months or less.Short Term conditions cover the time when the equipment is in transit from the factory to the dealer or from the dealer to the customer site. The system should be stored under short term conditions for only two months or less.The vacuum pump has the following specifications for long term storage:Long Term Temperature Range Minimum temperature ... 0 °C (32 °F) Maximum temperature ... 40 °C (104 °F)Long Term Range of Humidity Minimum Humidity "Non-condensing" ... 5% Maximum Humidity "Non-condensing" ... 95%Long Term Storage - Long Term defines the storage period of three to twelve months.The system can be stored under long term conditions without any additional concerns. If the UPS is stored longer than one year, you will need to change the oil for the vacuum pump. Thereafter, change the oil in the vacuum pump annually. After completing the oil change for the vacuum pump, you will need to energize the vacuum pump. Operate the vacuum pump for four hours. Operation of the pump will ensure proper lubrication of the seals for the vacuum pump.The vacuum pump is shipped from Service Parts without oil. Therefore, you are not required to change the oil for the vacuum pump for any inventory from service parts.Do not utilize a vacuum pump that has exceeded specifications for storage of the vacuum pump. Do not utilize a vacuum pump that has exceeded the operational environmental specifications of the vacuum pump. The vacuum pump must be replaced. The replacement cost of the vacuum pump is not a warrantable repair. Setup Procedure
The vacuum pump has a tamperproof label. This prohibits the service technician from utilizing a 120 VAC source to begin the process for vacuum draw on the flywheel during the commissioning procedure. A tamperproof label that is corrupted will void any warranty claim that is associated
