D. At full load, the chiller will discharge
approximately15,000BTU’sperhourper
ton of cooling.
E. On blower units, air discharge duct work
shouldbesizedbyaqualiedHVAC
engineer. Sizing shall be according to
rated CFM at the static pressure of .90
inchesofwater.Seegureatright.
F. On blower units, a damper control
assembly is required in low ambient
temperature areas or when outdoor air
make-up is used. The assembly works
in conjunction with refrigerant head
pressuretoregulateairowtomaintain
proper refrigerant head pressure when
condenser intake air temperature will be
lessthan60°F.Seeguretotheright.
G. All air cooled units MUST have all enclosure panels in place before operating
compressor. Air will not be drawn through the condenser coil if the panels are not in
place. Starting the unit without the enclosure panels in place will result in a refrigerant
fault.
H. Condenser Air Filtering.Usealterthatproducesverylowairowrestrictions.
GenerallyadisposableberglasslterwithaMERVratingof2-3providesadequateair
ltration.Thepurposeofthelteristopreventlargeparticlessuchasdust,lintanddebris
fromfoulingthecondenser.Youshouldbeabletoseethroughtheltermedia.Using
restrictiveltermediacancauselossofchillercapacity,difcultyrunninginwarmweather

Typical Filter materials.
Typical Filter shown on 10 ton air-cooled unit.
WARNING: Do not attempt to start or operate an air-cooled portable chiller without all cabinetry
panels in place. Air-cooled chillers require air to be drawn through the air-cooled condenser. This
will not occur if the panels are not in place.
