General Technical requirement For TE :i) Firm shall have valid BIS License conforming to IS:1475(Part-1)2001(Reaffirmed2007).ii)iii)iv)The water Coolers shall be suitable for operation on 230 V +/-10 %,50 Hz,singlephase A.C.supply.The tenderers shall declare specn. details of non-CFC compressor.(a) During inspection production routine tests as mentioned in clause 7.2 ofIS1475(Part-1):2001(reaffirmed 2007) will be carried out as acceptance test on upto10% of the samples from the lot offered for inspection.(b) Complete testing facilities should be available as per IS: 1475(part-1) withthe firm with instruments accuracies as per clause 7.6 of the specification.v) Tank shall be fabricated from S.S Sheet of 0.8mm minimum thickness as per AISI 304and shall be made by electrically seam welded lap joints or alternatively from 0.63mmthickness Stainles steel sheet with PUF insulation. However tank fabricated by doubleseam jointing is also acceptable if the same is reinforced and sealed by lead-freesolder material. Use of lead soldering material for sealing the joints of water tankis not permitted. Water tank cover and lid bottom shall be made of 1.25mm aluminimumsheet duly anodised/eppoxy painted/high impact polystyrene (HIP) of1.5mm thickness.Positive locking of the lid is to be provided (lock with two keys). Adrain valve at the bottom of the storage tank to be provided to draw outwater while cleaning.vi)The cabinet of the water cooler shall be made of GS sheet of 1.0mm. The front panelbelow the water outlets in the storage type water coolers shall be made ofstainless steel of 0.8mm. The drain pan for storage type water coolers shall be made ofstainless steel sheet of 0.63mm upto size 40 ltrs/hr and beyond 40 ltrs/hr of 0.8mmthickness. The bottom pedestal shall be made of 2.65mm minimum thick stainless steelsheet. Pedestal shall have a minimum ground clearance of 100mm for ease ofcleaning.Pedestal shall be strong enough to withstand weight with storage tank fulland shall be reinforced to prevent askewing. The body shall be held securely with thepedestal with stainless steel nuts and bolts.The drain size should be 25mm or above.In case water outlets are provided on three sides then all the three lower panelsshould be made of aluminium sheet or stainless steel sheet.vii) The mild steel components used in the manufacture of the cabinet shall beindividually degreased, pickled, scrubbed and rinsed to remove grease, rust, scaleor/any other foreign elements. Immediately after pickling the M.S. parts shallbe given phosphating treatment. The components alongwith the front panels shall then begiven a primer coat with a finish coat of stove enamel paint. The finish shall be smoothand uniform with hard tough film of the enamel adhering to the surface. The finishshall be free from all the visible defects and shall not chip when tappedlightly with a dull pointed instrument. Alternative method of corrosion protection likeplastic powder coating, electrostatic painting shall be permitted.viii) Refrigeration coils to be fully soldered to the outside of the tank for good thermalcontact and not merely tack welded.ix)The tenderers are required to furnish wattage/litre for the model as actually obtainedin their product at rated conditions.x) There shall not be any gap between water tank cover (mask) and water tankto prevent rodent/inspect/dust entry.xi)xii)Condensor fan motor shall be capacitor start and capacitor run(CSR) or permanently splitcapacitor(PSC)or alternatively permanently lubricated motor may be provided.Water tank overflow should be adequately covered with strainer such as wire

meshetc. to avoid rodent/insect/dust entry.xiii) The power factor of water cooler shall not be less than 0.85 at capacity rating testconditions.xiv)xv)The thermostat shall conform to IS:11338-1985 (Reaffirmed 1999) The position of thethermostat shall be adjustable through a rotary switch mounted on the front or sidepanels. Minimum and maximum of the thermostat setting shall be from 10 deg C and 25deg.C which shall be marked.During inspection performance of thermostat shall also be checked at minimum and maximumpositions.SAMPLING:No of samples for acceptance test shall be 10% of the offered lot capacitywise subject tominimum of 1 number.Pre- despatch ispection of stores against the R/C shall be reported as perinspectionReport proforma CSIDC Technical DWC.
