E. Valvesandltersmaybeinstalledintheprocesswaterpipingtofacilitateserviceand
maintenance provided that such devices maintain the full inside diameter of the process
connection. If installed, all such devices must be open and clean during unit operation.
F. It is important to check all external process connections for leaks prior to starting the
unit.Itisalsoimportanttocheckexternalconnections,internalhoseclampsandtting
connections for leaks after servicing the unit.
2.4 MAKE-UP WATER SUPPLY CONNECTION
A. The automatic water make-up system continually monitors the
reservoirtankandllsitwhenneeded.Connectasfollows:
1. Usingappropriatelyratedhoseoruidpipingconnectthe
“watermake-up”connectiontotheplant’swatersource.
2. Minimum make-up water supply pressure is normally 20 psi.
3. Install an owner supplied shut off valve in the make-up water supply line. Install
this valve on the outside of the unit.
4. Useabackowpreventiondeviceasrequiredbylocalcodestopreventpossible
contamination of potable water.
B. Do not use automatic water make-up system when operating with glycol below 48°F.
C. Whenthelevelsensorindicatesalowtanklllevelanalarmsignalisinitiated.The
unit will continue to operate while in a low tank level state but an alarm screen will
bedisplayeduntiltheuidllisattherecommendedlevel.Accesstoalloperating
parameters will be available through the menu function.
2.5 AIR COOLED CONDENSER
A. Air-cooled condensers require ambient air temperatures between 60°F and 95°F for
efcientoperation.Operatingabove95°Fmayresultinelevatedcondensingpressures
and eventual shut-down on the high pressure limit switch. Air temperatures below 60°F
may result in over condensing pressures and cause a low pressure refrigerant fault.
ConsultwiththeManufacturer’s service department for more information on operating
with ambients air temperatures above 95°F or below 60°F.
B. Airowisgeneratedbythemotormountedpropellerfan(s)orcentrifugalblower(s).Air
owisfromtheoutsideofthechiller,throughthecondenserandexhaustedthroughthe
top of the unit. On centrifugal blowers models, exhaust air can be ducted outside of the
plant’sinteriorenvironment.SpecialductworkisrequiredandaHVACcontractorshould
beconsultedforsizingandmaterialspecications.Exhaustaircannotbeductedon
propeller fan models.
