2.1 GENERAL
A. Chillers are shipped skid mounted and wrapped in plastic prior to shipment. Check the
overall condition of the equipment prior to accepting delivery. Check for visible damage
and document any evident damage on the delivery receipt. Shipping damage is the
responsibility of the carrier.
B. Allprocesspipingmaterials(suchashose,rigidpiping,valvesorlters)usedinprocess
water piping circuitry must be rated for 100°F minimum temperature and 100 PSI
minimum pressure.
C. All such materials must have the equivalent or larger diameter of the particular process
connection that length of process water piping is connected to.
2.2 UNIT LOCATION
A. Foundation. The chiller must be installed on a rigid and level mounting surface with
adequate strength to support the operating weight of the chiller including the weight of
water and attached piping.
This unit will contain water or water/glycol when operating. Locate the chiller
where an unforeseen uid leak will not cause damage to the surroundings or
install the unit in such a way that an unforeseen uid leak will not damage its
surroundings.
B. For air-cooled and water-cooled models:
1. These units are designed for indoor use only.
2. Formostefcientoperation,locatethechillerinalevel,clean,dryandwell
ventilated environment.
C. For air-cooled models:
1. The unit has an air-cooled refrigerant condenser. For air- cooled condensers, a
motor driven fan (on models from 5 to 20 tons) or a centrifugal blower (standard
onmodelsfrom25to30tonsandoptionalonothermodels)generatesairow
through the condenser to remove heat from the refrigerant system. The air
cooledcondenserontheunitwilldischargeapproximately15,000BTU’sperhour
pertonofcoolingandtheairowrateisapproximately1,000cfm/nominalton.
2. The unit must have a minimum entering air temperature of 60°F and a maximum
enteringairtemperatureof95°Fforefcientoperation.
3. The unit must have a minimum of two feet clearance at the air intake and six
feet at the vertical exhaust air discharge and must have adequate ventilation to
dissipate the rejected heat. The unit must not be placed in non-ventilated areas.
4. The unit must have all enclosure panels in place before operating the
compressor. Air will not be drawn through the condenser coil if the panels are not
in place. Starting the unit without all the enclosure panels in place will result in a
high pressure refrigerant fault.

5. Units with a motor-driven fan may not use duct work unless a booster fan of
equal volume rating has been installed in the duct.
2.3 TO AND FROM PROCESS CONNECTIONS
A. Useappropriatelyratedhoseoruidpipingtoconnecttheprocesspipinggoingtoyour
process to the “to process” connection on the chiller.
B. Useappropriatelyratedhoseoruidpipingtoconnecttheprocess
piping coming back from your process to the “from process” connection
on the chiller.
C. Install a high volume basket strainer in the From Process line with
isolationvalves.Abasketstrainerorbaglterwithameshscreen
of 20-40 microns will protect the unit. A “wye” type strainer is not
recommended because it does not have adequate debris holding
capacity.
D. Process water piping should be designed to avoid excessive elbows
and/orlengthsofpipeorhose.Ifusingexiblehoseavoidtighttwists
or curls and excessive lengths.
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 for leaks and internal hose clamps and
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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.

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
and fan motor overheating.

2.6 WATER-COOLED CONDENSER
A. Connect the facility cooling tower or city water supply to the
“condenser water in” connection on the unit.
1. Requiredowratefromacitywatersourceis1.5gpmat
65°F per ton of rated capacity.
2. Requiredowrateforatowerwatersourceis3gpmat85°Fpertonofrated
capacity.
B. Connect the facility tower system return or drain to the “condenser
water out” connection on the unit.
1. Note:Followalllocalcodesifdumpingtotheplant’s
sanitary or other drain.
C. The pressure differential requirement between the condenser “water in” and the
condenser “water out” lines must be 30 psi.
D. The installation of a strainer in the condenser “water in”
line is recommended. This removes solids from the water
supply and serves to protect the water saver (regulator)
valve.
E. The water regulator valve is normally factory set for
properoperation.Wheneldadjustmentsarerequired,
turn the adjusting nut on the top of the valve counter
clockwise to raise the refrigerant pressure and clockwise
to lower the pressure. Adjustments should be made only
when the chiller is running at full load.
