Page 5: Safety
1.0 Safety Safe operation of the 3AL vacuum system requires strict adherence to all local and national codes. In addition to these requirements, specific dangers are identified within this manual and should be considered when installing and operating your Airtech vacuum system.
Page 6: Intended Use
1.2.7 Surfaces within the 3AL vacuum system can be cause burns or scalding. Do not touch internal surfaces within the system. 1.2.8 The 3AL can produce vacuums to 29 inches Hg vacuum. Be sure that the vacuum has been vented to atmosphere before working on the 3AL system.
Page 7: Prohibited Uses
Special material versions should be selected for these types of applications. 3.3 Do not use the 3AL on lethal gases. The 3AL is not gas tight and is not intended for these applications.

Page 9 3AL2430 1.85/7 4.4 The 3AL is an air cooled unit and therefore sufficient space as noted in this table must be allowed around the unit to ensure adequate air flow for cooling and proper operation. Front refers to the air inlet through the heat exchanger; back refers to the air outlet through the perforated metal grid and side refers to any other side of the unit.
Page 10: Transportation & Handling
5.0 Transportation and Handling 5.1 The 3AL liquid ring vacuum system is designed to be lifted easily by a forklift; this is the recommended method of transport. 5.2 If lifting the 3AL using a crane, use two lifting belts routed below the system in the area where the forklift would normally lift the unit.
Page 11 6.5 Consider local installation details to minimize vibration. Maximum vibration allowed is 0.177 inches/sec (4.5 mm/sec). Consult a vibration expert if this value is exceeded. For most applications, a special foundation or base plate is not required to achieve this level of vibration and the unit can simply be bolted to the floor.
Page 12 6.7 Once the electrical connections are complete, reattach the junction box cover and then reattach the 3AL metal cover sheets, ensuring that the wire is properly routed through the cut out in the side sheet near the bottom of the unit.
Page 13 6.10.1.1 Remove the pipe plug before connecting the inlet. The pipe plug is inserted prior to shipment to keep foreign bodies out of the operating liquid sump. 6.10.2 A check valve is included with each 3AL system and additional check valves are not required.
Page 14: Start-Up
6.13.5 Add a discharge pressure switch if connecting the system to a downstream process which could cause excessive back pressure onto the unit. 7.0 Start-up 7.1 Visually check the operating liquid level in the operating sump on the liquid level gauge on the back of the unit. Add or remove water as necessary to achieve a level of water just below the level of the overflow connection.
Page 15: Operation
9.0 Operation 9.1 Continuous operation at a maximum vacuum is possible. The power consumption of the vacuum system is at its lowest at this operating condition. In case of no load operation, we recommend operation at this condition (e.g. with the inlet blanked off from the process) rather than open flow to atmosphere.
Page 16: Servicing
10.3.3.3 Repeat this procedure until the system is free of debris or foreign matter. 11.0 Servicing 11.1 Do not attempt to service the system without consulting Airtech, Inc. for assistance. Normally, no service is required and the need for service may indicate a process problem that must be addressed prior to re-commissioning.

Remove the shroud covering the fan (note: cooler may need to be removed to remove the shroud). Turn the fan by hand (do not use leverage). If the shaft will not come free, the unit must be serviced by an authorized service center. Please contact Airtech for assistance.
