Moving and Storage
Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packag-
ing. Do not stack more than three units in total height. Vertical units may be stored one upon another to a maximum height
of two units. Do not attempt to move units while stacked. When the equipment is received, all items should be carefully
checked against the bill of lading to be sure all crates and cartons have been received. Examine units for shipping damage,
removing the units from the packaging if necessary. Units in question should also be internally inspected. If any damage is
noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage.
Unit Location
 Locatetheunitinanindoorareathatallowsforeasyremovalofthelterandaccesspanels.Locationshouldhave
enoughspaceforservicepersonneltoperformmaintenanceorrepair.Providesufcientroomtomakewater,electrical
andductconnection(s).Iftheunitislocatedinaconnedspace,suchasacloset,provisionsmustbemadeforreturnair
tofreelyenterthespacebymeansofalouvereddoor,etc.Anyaccesspanelscrewsthatwouldbedifculttoremoveafter
the unit is installed should be removed prior to setting the unit. On horizontal units, allow adequate room below the unit for
a condensate drain trap and do not locate the unit above supply piping. Care should be taken when units are located in
unconditioned spaces to prevent damage from frozen water lines and excessive heat that could damage electrical
components.
Installing Vertical Units
Prior to setting the unit in place, remove and discard the compressor hold down
shipping bolt located at the front of the compressor mounting bracket.
 Verticalunitsareavailableinleftorrightairreturncongurations.Topairdis-
charge vertical units should be mounted level on a vibration absorbing pad slightly
largerthanthebasetoprovideisolationbetweentheunitandtheoor.Itisnot
necessarytoanchortheunittotheoor(seeright).
 Bottomowunitsshouldbemountedlevelandsealedwelltooortopreventair
leakage.Bottomowunitsrequirethesupplyairopeningtobecutatleast1/2˝larger
thantheunit’sairoutlet.Protecttheedgesofcombustibleooringwithsheetmetal
over-wrap or other non-combustible material.
WARNING: Before performing service or maintenance operations on a system, turn off main
power switches to the indoor unit. If applicable, turn off the accessory heater power switch.
Electrical shock could cause personal injury.
Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical
components.Onlytrainedandqualiedservicepersonnelshouldinstall,repairorserviceheatingandairconditioningequip-
ment.Untrainedpersonnelcanperformthebasicmaintenancefunctionsofcleaningcoilsandcleaningandreplacinglters.
All other operations should be performed by trained service personnel. When working on heating and air conditioning equip-
ment, observe precautions in the literature, tags and labels attached to the unit and other safety precautions that may apply.

Installing Horizontal Units
Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket
prior to setting the unit in place. Horizontal units are available with side or end discharge. Horizontal units are normally sus-
pendedfromaceilingbysix3/8-inchdiameterthreadedrods.Therodsareusuallyattachedtotheunitbyhangerbracket
kits furnished with each unit.
Lay out the threaded rods per the dimensions below. Assemble the hangers to the unit as shown. Securely tighten the
brackets to the unit using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to
thebracket,adoublenutisrequiredsincevibrationcouldloosenasinglenut.Toallowlteraccess,onebracketonthelter
sideshouldbeinstalled180°fromthepositionshowninthegurebelow.Theunitshouldbepitchedapproximately1/4-inch
towards the drain in both directions to facilitate the removal of condensate. Use only the bolts provided in the kit to attach
hanger brackets. The use of longer bolts could damage internal parts.
 Someresidentialapplicationsrequiretheinstallationofhorizontalunitsonanatticoor.Inthiscase,theunitshould
be set in a full size secondary drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible
condensateoveroworwaterleakagedamagetotheceiling.Thesecondarydrainpanisusuallyplacedonaplywoodbase
isolated from the ceiling joists by additional layers of vibration absorbing material.

Duct System
An air outlet collar is provided on vertical top air discharge units and all horizontal units to facilitate a duct connection
(verticalbottomowunitshavenocollar).Aexibleconnectorisrecommendedfordischargeandreturnairductconnec-
tionsonmetalductsystems.Uninsulatedductshouldbeinsulatedwithaminimumof1-inchductinsulation.Applicationof
the unit to uninsulated ductwork in an unconditioned space is not recommended as the unit’s performance will be adversely
affected.
If the unit is connected to existing ductwork, check the duct system to ensure that it has the capacity to accommodate
the air required for the unit application. If the duct is too small, as in the replacement of heating only systems, larger duct-
work should be installed. All existing ductwork should be checked for leaks and repaired if necessary.
 Theductsystemshouldbesizedtohandlethedesignairowquietlyandefciently.Tomaximizesoundattenuationof
theunitblower,thesupplyandreturnplenumsshouldincludeaninternalductlinerofberglassorconstructedofductboard
fortherstfewfeet.Onsystemsemployingasheetmetalductsystem,canvasconnectorsshouldbeusedbetweenthe
unitandtheductwork.Ifairnoiseorexcessiveairowisaproblem,theblowerspeedcanbechanged.
Water Piping
 Theproperwaterowmustbeprovidedtoeachunitwheneverthe
unitoperates.Toassureproperow,usepressure/temperatureports
todeterminetheowrate.Theseportsshouldbelocatedatthesupply
andreturnwaterconnectionsontheunit.Theproperowratecannot
be accurately set without measuring the water pressure drop through
the refrigerant-to-water heat exchanger.
 Allsourcewaterconnectionsoncommercialunitsarettingsthat
accept a male pipe thread (MPT). Insert the connectors by hand, then
tightenthettingwithawrenchtoprovidealeakproofjoint.Whencon-
necting to an open loop (groundwater) system, thread any copper MPT
ttingintotheconnectorandtighteninthesamemannerasdescribed
above.
All source water connections on residential units are swivel piping
ttings(seeFigure4)thataccepta1-inchmalepipethread(MPT).
The swivel connector has a rubber gasket seal similar to a rubber hose
gasket,whichwhenmatedtotheushendofany1-inchthreaded
pipe provides a leak-free seal without the need for thread sealing tape
or compound. Check to ensure that the rubber seal is in the swivel
connector prior to attempting any connection. The rubber seals are
shipped attached to the waterline. To make the connection to a ground
loopsystem,matethebrassconnector(suppliedinCK4Lconnectorkit)
against the rubber gasket in the swivel connector and thread the female
locking ring onto the pipe threads, while maintaining the brass connec-
tor in the desired direction. Tighten the connectors by hand, then gently
snugthettingwithplierstoprovidealeak-proofjoint.Whenconnectingtoanopenloop(groundwater)system,threadany
1-inchMPTtting(SCH80PVCorcopper)intotheswivelconnectorandtighteninthesamemannerasnotedabove.The
openandclosedlooppipingsystemshouldincludepressure/temperaturetapsforserviceability.
 Neveruseexiblehosessmallerthan1-inchinsidediameterontheunit.Limithoselengthto10feetperconnection.
Check carefully for water leaks.

ENVISION RESIDENTIAL INSTALLATION MANUAL
Water Quality
In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be pres-
ent, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time,
loseheatexchangecapabilitiesduetoabuildupofmineraldepositsinside.Thesecanbecleaned,butonlybyaqualied
service mechanic, as special solutions and pumping equipment are required. Desuperheater coils can likewise become
scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger
mayrequireoccasionalushing.
Units with cupronickel heat exchangers are recommended for open loop applications due to the increased resistance to
build-up and corrosion, along with reduced wear caused by acid cleaning.

Condensate Drain
On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a
3/4-inchPVCfemaleadapterandaexibleconnectinghose.Thefemaleadaptermayexiteitherthefrontorthesideofthe
cabinet.Theadaptershouldbegluedtotheeld-installedPVCcondensatepiping.Onverticalupowunits,acondensate
hose is inside all cabinets as a trapping loop; therefore, an external trap is not necessary.
On horizontal units, a PVC stub is provided for condensate drain piping connection. An external trap is required (see
below).Ifaventisnecessary,anopenstandpipemaybeappliedtoateeintheeld-installedcondensatepiping.

Oncepipingiscompletedbetweentheunit,pumpsandthegroundloop(seegurebelow),nalpurgingandcharging
oftheloopisrequired.Aushcart(ora1.5HPpumpminimum)isneededtoachieveadequateowvelocityintheloopto
purge air and dirt particles from the loop itself. Antifreeze solution is used in most areas to prevent freezing. Flush the sys-
temadequatelytoremoveasmuchairaspossiblethenpressurizethelooptoastaticpressureof40-50PSI(summer)or
50-75PSI(winter).Thisisnormallyadequateforgoodsystemoperation.Loopstaticpressurewilluctuatewiththe
seasons.Pressureswillbehigherinthewintermonthsthanduringthecoolingseason.Thisuctuationisnormalandshould
be considered when initially charging the system.
Afterpressurization,besuretoopentheplug1turnintheendofthelooppumpmotor(s)(ifapplicable)toallowtrapped
airtobedischargedandtoensurethatthemotorhousinghasbeenooded.Ensurethatthelooppumpsprovideadequate
owthroughtheunit(s)bycheckingthepressuredropacrosstheheatexchangerandcomparingittotheunitcapacitydata

Open Loop Ground Water Systems
Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control
valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize
mineralformationduetoairexposure.Insureproperwaterowthroughtheunitbycheckingpressuredropacrosstheheat

Desuperheater Connections
 Tomaximizethebenetsofthedesuperheateraminimum50-gallonwaterheaterisrecommended.Forhigher
demandapplications,usean80-gallonwaterheaterortwo50-gallonwaterheatersconnectedinaseriesasshown
below. Electric water heaters are recommended. Make sure all local electrical and plumbing codes are met for installing
a desuperheater. Residentialunitswithdesuperheaterscontainaninternalcirculatorandttings.
Note: Under certain conditions, Envision dual capacity units operate with very low refrigerant discharge temperatures,
producing little or no water heating capability. This scenario occurs when the unit is operating with cold entering source
water (loop or well). Allowing the desuperheater pump to operate during these conditions actually removes heat from the
DHW circulating through the unit. To overcome this, Envision unit microprocessors have been programmed to disengage
the desuperheater pump during such conditions. (During low capacity cooling operation, the pump will operate only if
theDHWtemperatureenteringtheunitislessthantheliquidlinetemperatureplus35ºF.Duringhighcapacitycooling
operation,thepumpwilloperateonlyiftheDHWtemperatureislessthantheliquidlinetemperatureplus60ºF.)Using
apreheattank,asshowninFigure12,willmaximizedesuperheatercapabilities.
