controlled greasing canisters shall deliver 350 psig lubrication on a precision cycle to increase bearing longevity and practically eliminate bearing maintenance.

** NOTE TO SPECIFIER ** Delete bearing unit not required.1) All four unit bearings are to be automatically lubricated every second day

from a 240 cc lubrication canister.2) All six unit bearings are to be automatically lubricated every second day

from a 240 cc lubrication canister.3) All eight unit bearings are to be automatically lubricated every second

day from a 240 cc lubrication canister.b. The greasing canisters with pump driven microprocessor are to be located in

the main control panel for ease of adjustment. The grease canister shall contain a minimum quantity of grease to ensure two year supply prior to canister tank replacement.

** NOTE TO SPECIFIER ** Delete if not required.14. Humidification Plenum:

a. G90 galvanized steel. The unit shall include the humidifier mounted, wired and tested from the factory. Gas to steam microprocessor controlled humidifier. The humidifier is to automatically cool discharged hot water to 140 degree F (60 degree C) to meet governing code requirements and to prevent damage to PVC drain piping.1) Control to ±3% RH.2) Steam output rangeability up to 40 to 1 closely tracks humidity set point.3) Low nitrogen oxide (NOx) emissions of less than 20 ppm.4) Diagnostic test at unit start-up verifies system performance.5) 82% burner efficiency rating.6) Variable speed blowers and modulating gas valves provide consistent

humidity output.7) Full burner modulation and PID control provide accurate, responsive, and

adjustable RH control.8) The temperature sensor enables the controller to hold water at a preset

temperature allowing rapid response to a call for humidity, enables freeze protection, and allows rapid warm up.

** NOTE TO SPECIFIER ** Delete if not required.15. "Oil Mist" Filtration:

a. The unit will be complete with two stages of filtration. The primary filtration will be specifically designed to capture "oil mist" particulate. Farr ECO filters four inches (102 mm) thick media will be installed in a flat bank filter rack around the unit. The ECO filters will be equipped with a drain trough and these are to be connected to a common drain pipe from the unit. The secondary level of filtration will consist of two inches (51 mm) thick 30% efficient pleated filters.

16. Unit Efficiency Ouput: 80% of input (MBH).** NOTE TO SPECIFIER ** Delete model not required.
