The system should be able to monitor and guarantee specific temperatures up to 1900F so that the conveyor belt stops until a temperature set by the operator has been achieved. Under normal operating conditions, stops to achieved desired temperatures will not slow the operation of the tunnel washer by more than 5% in an 8 hour work day; (7) The prewash section, wash section, recirculated rinse section, and non-recirculated final rinse section shall each result in a spray sufficient to thoroughly cover each cage being washed in all positions across the belt so that at the end of the process each cage is visibly thoroughly clean, free of visible soap residue, andculturable bacterial numbers are reduced by a minimum of 99% (determined by counts from swabs taken from cages before and after the washing process).; (8) Jet spray headers shall be provided and shall be secure but easy to remove without tools; (9) The tunnel washing system shall operate so that light plastic cages are hydraulically held onto the conveyor belt; (10) The smoothness of the interior of the chamber and tanks will be assessed by sight, touch, and performance (preventing the build up of debris); (11) The booster heater with instantaneous steam to water heat exchange shall raise the temperature of the NIOSH tap water supply by a minimum of 800F; (12) The statement in the original specifications "The supply filter assembly will be complete with a periodic automatic reversing flush" refers to a self cleaning filter to strain debris provided by the wash pump to a size that will prevent the plugging of jet sprayers. This filter assembly shall be easily accessible by the operator; (13) The statement in the original specifications "the washer interior will be automatically cleaned and descaled" means that the cleaning/descaling system can be activated so that each tank is drained, cleaned and descaled, flushed, and refilled automatically in an operator programmable manner that greatly reduces or eliminates the need to manually clean the tanks; (14) A water hammer eliminator will be provided by NIOSH; (15) Acid neutralization of effluents will be done by NIOSH; (16) The heat in the dryer shall be adjustable with a maximum temperature which should be known, disclosed to NIOSH, specified by the offer and between 2050F and 2250F; (17) The dryer provided shall be able to dry polycarbonate cages so that they are free of visible beads of water and can be filled with bedding or stored immediately; (18) An exhaust system provided by NIOSH will be available in the room on the unload side.
