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maybe
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.
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fansor
centrifugalblowers.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 motor mounted fan models.
C. A free air space of at least two (2) feet is required at
the condenser intake and six (6) feet at the condenser
dischargetoallowforproperairow.
