Applications (cont.)

Application

ConsiderationsIt is important for air conditioning systems to beproperlysizedforeachapplicationinordertoachievedesiredtemperatureandhumiditylevels.ItisstronglyrecommendedthataprofessionalengineermatchthePTACunitswiththebuildingstructureandclimate.

The following application considerations are allimportantinchoosingtheproperPTACsystemforthebuildingstructure.

UNDERSIZING

IfaPTACunitisundersized(coolingcapacityislessthan required capacity for an application), the unitwillnotbeabletocoolthespacedowntothedesiredtemperatureduringveryhotdays.

OVERSIZING

IfaPTACunitisoversized(coolingcapacityisgreaterthanrequiredcapacityforthespecificapplication),theunitwillcoolthespacedowntothedesiredtemperaturetoo quickly creating a cool, yet excessively humid,space.

AIR INFILTRATION

Excessive air infiltration can intensify problemsassociated with undersizing or oversizing a PTACunit. This can be the cause of insufficient cooling,dehumidification,orheating.Sourcesofairinfiltrationincludevents, gaps aroundwindows anddoors, andimproperlysealedfloors,ceilingorwalljoints.

Whether it is an exact replacement unit or a newconstructionproject,Islandaireisthesmartchoiceforallyourairconditioningandheatingneeds.

Indoor Air QualityIn addition to an already quiet unit, we have co-developed an indoor air quality option calledDr.PTAC.

Condensate Drain Kit

Figure 11 External Drain Installation

Figure 12 Block-Off Plate Installation

External Drain InstallationPart Number 6140165 The drain kit can be installed as an external drain on the left or right side drain opening on the sleeve. Determine which drain opening will provide the best drainage for the installation.

Local codes will determine the proper method for condensate disposal. The drain kit must be installed before installation of the wall sleeve condenser grille.

1. Remove the rear enclosure panel and the cardboard sleeve stiffener.

2. Install the outdoor drain fitting and one of the outdoor drain fitting gaskets over one of the drain holes on the rear of the wall sleeve. Secure this assembly to the rear of the sleeve with two sheet metal screws into the holes provided in the wall sleeve.

3. Cover and seal the remaining drain hole using the remaining outdoor drain gasket, cover plate and remaining sheet metal screws provided

Condensate Drain Kit Part Number 4090661An indoor/outdoor drain kit is available as an accessory item. When a drain kit is to be installed, do so before installing the wall sleeve in the wall.

During periods of high humidity and/or during heat pump operation condensate water will collect in the bottom pan of the chassis. When the chassis bottom pan is full, the water will overflow into the wall sleeve and out the drainage holes on the back edge of the wall sleeve.

The Condensate Drain kit contains an overflow tube to direct excess condensate water from the bottom of the sleeve to either an internal or external drainage path. Because heat pumps generate condensate even during the heating season, it is recommended to always use a drain kit with heat pump models. Determine whether the kit should be installed as an internal or external drain system.

OUTDOOR GASKET

OUTDOOR GASKET OUTDOOR

DRAIN FITTING

BLOCK-OFFPLATE

SHEET METAL SCREWS

SHEET METAL SCREWS

Periodically inspect drain passages for blockage. Blow out drain tubing annually to prevent overflow from entering the building.

This drain kit serves only as a link between the unit and field-supplied condensate drain system.

Installing the kit without connecting it to a drainage system will result in inadequate condensate removal, possible leakage and corrosion.

NOTE

Figure 15 Block-Off Plate Installation

INSTALL BLOCK-OFF PLATES AND GASKETS OVER LEFT AND RIGHT EXTERIOR DRAIN HOLES

Internal Drain Installation Part Number 6140165

The drain kit can be installed as an internal drain on the bottom of the wall sleeve to allow condensate to drain into an internal drain system inside of the building. Locate the drain so that it will be on the room side of the wall when the cabinet wall sleeve is installed.

NOTE: The drain kit must be installed prior to the installation of the wall sleeve.

1. Locate an area on the wall sleeve that will be inside the room when the sleeve is installed. If a subbase is installed, locate the kit a minimum of 3 1/2” from the front flange of the wall sleeve. This clearance will provide adequate clearance for the subbase.

2. Cutout the template shown to the right. Using this template, locate and drill the drain kit holes as close to the outside wall as possible.

3. Using detail A (above) as a guide, assemble the drain gasket, drain fitting plate, and indoor drain fitting together. Install the assembly into the drilled holes and secure using the two indoor mounting screws provided. The screws must be inserted INSIDE the wall sleeve and TOP driven down into the drain fitting plate.

Ensure drain tube is not restricted. Cover the two screw heads with a good quality outdoor caulking (not supplied) for additional corrosion protection.

NOTE: If the drain fitting is not connected to an indoor drainage system immediately after the wall sleeve is installed; plug the hole with cork (not included) to prevent indoor water damage in case it rains.

4. Install a 1/2” ID tube or hose (not included) on the drain fitting and interconnect it to the drain system inside of the building. Ensure that there are no kinks or traps in tube or hose. Kinks or traps can cause improper drainage.

5. Install the two drain blank-off plates and outdoor drain gaskets on the outdoor portion of the wall sleeve as shown in figure 5. These components can be installed after the sleeve is secured in the wall opening just prior to the installation of the condenser grilleandchassis.

Manufacturersofsolidstateoutputthermostatsincludeloadingresistorsintheirinstallationkits.These(560Ohm 3W) resistors are meant to load thermostatsolidstateoutputs inorder for theoutputvoltage tobeeither0or24VAC,i.e.nofloatingvoltage.TheseresistorsareconnectedfromW,Y,Gtocommon(C),respectively

Youcanwire any typeof 24Vac thermostat straightinto the RemoteThermostat Interface on the PTACcontrolboard(seepage37).

Wireless Wall Thermostat

Wireless wall thermostats are designed to provideprecise temperature control without the installationlaborandexpenseofwiring.

•PoweredbyAAbatteries

•Mountsinanysuitablelocationthatwillprovideanaccurateroomtemperaturereading.

•Large LCD display provides the user withcurrent room temperature, set point temperature,time, program interval, and other system statusinformation.

RemoteControlNode

Used with a wireless wall thermostat, the RCNcommunicates with the thermostat using unlicensed900MHz,radiofrequencyenergy.

Energy Saving OptionsAutomatic Change-Over Remote MountedThermostatscanbeobtained toswitch fromheatingtocoolingandfromcoolingtoheatingautomatically.With automatic change over, the operation of theheating cycle or the cooling cycle is determined bythetemperaturerequirementofthespace.

Most thermostatswith this featureare set tochangeoverwhentheroomtemperaturevaries3-1/2°Ffromtheset-point.Theunitisplacedinthecoolingmodewhentheset-pointisover3-1/2°F;3-1/2oFundertheset point places the unit in the heating mode. This3-1/2°Fvariation is usually adjustable froma 1/2°Fdeadbandtoa5°Fdeadband.Eachcycleisrununtilthe set point temperature is reached, then that cycleisde-energized.Onsomethermostats, theautomaticchangeoverfunctioncanbeoverriddenmanuallybymovingthethermostatselectorswitchto“heat”orto“cool.”

The fan operation, with an automatic change overthermostat, is controlled by the fan selector switch.When placed in the “fan” mode, the fan runscontinuously.When placed in the “auto”mode, thefanwillonlyenergizewhen the thermostat calls forheatingorcooling.
