4 The presence of a dangerous volt- age is identified with this safety to this warning could damage the unit or affect its Manual contains basic information on the instal-lation, operating and Maintenance and should be followed carefully. It is essential that these instructions are carefully read before installation or commissioning by both the installation crew as well as those respon-sible for operation or Maintenance . The operating instructions should always be readily available at the location of the modification and spare parts manufacturingModifications or changes to the unit/ installation should only be carried out after consulting with ITT. Original spare parts and accessories authorized by the manufacturer are essential for compliance. The use of other parts can invalidate any claims for warranty or regulations for the owner/operatorAll government regulations, local health and safety codes shall be complied dangers due to electricity must be avoided (for details consult the regulations of your local electricity supply company).

5 Identification of safety and warning symbolsNOTE!Qualifications of personnelAn authorized (certified) electrician and mechanic shall carry out all pictures in this Manual may differ somewhat from the delivered jet aerator depending on the size and AND STORAGEPRODUCT DESCRIPTIONI ntroductionThank you for buying a Flygt designed submersible self-aspirating jet this installation Manual you will find general infor-mation on how to handle, install and service the jet aerator to give it a long and reliable parts list and installation Manual of the pump that forms part of the jet aerator give full technical data on your particular , self-aspirating jet aerator intended for aerating and mixing of waste water. The Flygt jet aera-tor is based on a submersible Flygt pump and a Flygt designed ejector jet aerator is designed for use in small to medium tanks and basins, where the tasks include BOD/COD reduction, mixing, homogenization, odor control and/or oxidation of nutrients.

6 Common applications are the activated sludge process, aerobic sludge digestion, retention basins and storm water further information on applications contact your ITT dataLiquid temperature: maximum 40 C (104 F)For temperature higher than 40 C (104 F), please contact your ITT density: maximum 1100 kg/m ( lb per US gallon).The pH of the pumped liquid: - 14 Choose Stainless steel for the pH of the pumped liquid > flow data: given at 1 atm. and 20 C (68 F).Oxygen transfer data: 1 atm, 20 C (68 F) water tem-perature, and dissolved oxygen content of 0 mg O2 alternativesP = Semi permanent wet well arrangement with pump installed by means of twin guide bars with automatic connection to discharge.

Never work alone. Use a lifting harness, a safety line and a respirator, as required. Do not ignore the risk of drowning!2. Make sure there is sufficient amount of oxygen and that there are no dangerous gases within the work Check the explosion risk before welding or using electric hand Observe strict cleanliness.

8 Do not ignore health Bear in mind the risk of electrical Make sure that the lifting equipment is in good condition, and comply to local Provide a suitable barrier around the work area, for example a guard Make sure that you have a clear path of Use safety helmet, safety goggles and protec tive All personnel who work with sewage systems should be vaccinated against diseases they may be exposed A first-aid kit must be close at Note that special rules apply to installation in ex-plosive all other health and safety rules and local codes and recommendationsTo ensure proper installation , see please dimensions on the dimensional the horizontal positioning of the jet aerator ac-cording to the dimensional jet aerator should be installed in such a way that the water jet propagates freely in water without meet-ing obstacles or side walls and the direction of flow created does not conflict with flows of other mixers or jet aerators has to be within specified submergence range.

9 installation should be in such a way that the pump inflow is not disturbed and air is not sucked into the more detailed information, please contact your ITT equipmentAlways pay extra attention to safety aspects when working with lifting equipment is required for handling the jet aera-tor. The lifting chain and the schackle should be in stainless steel and inspected every year. S-installationThe minimum height between the lifting hook and the ground must be sufficient to be able to lift the jet aera-tor out of the lifting equipment could cause damage if the pump should stick when being sure that the handling equipment is securely that the lifting handle and chain are in good further information of installation , contact your ITT jet aerator on siteThe various parts shall be assembled as indicted in the assembly instruction, using the screws supplied and applying the recommended tightening torques. Always use the supplied lifting equipment Pump lift and Chain sling when lifting the jet aerator.

10 Assembly of the lifting equipment must be done according to the assembly ! Stay clear of suspended loads. Always lift the pump by its lifting handle - never by the motor cable or tightening torquesFlygt standard screws in Nm and ft-lb. Chart valid only for lubricated screws. Use suitable screwsTo maintain screw tightness and prevent screws from seizing or getting stuck use a suitable lubricant such as Kl ber ALTEMP Q alternativesThe total submergance H is the depth from the liquid surface in the tank to the bottom of the distance Z is measured from the bottom of the tank to the floor above the pump is installed on a discharge connection fixed to the base of the tank, with the ejector system mount-ed on it. This installation is recommended for large jet aerators, where moving the pump is more practical than moving the ejector jet aerator is placed on the bottom of the tank without the need for any kind of anchoring device.
