Vert-I-PakInstallationRecommendations

Forproperunitperformanceandmaximumoperatinglifepleaserefertotheminimuminstallationclearancesbelow.

Figure1

VERT-I-PAK® units must be installed on an outside wall. Confined spaces and/or covered areas should be avoided. Units should be installed no closer than 12" apart when two units are side by side. If three of more units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical clearance of 60" should be maintained between units. Units installed on the bottom floor should be mounted at least 6" off of the ground.

Any time obstructions are present use the following guidelines for proper spacing from the VERT-I-PAKlouver:

For minor obstructions such as lamp poles or small shrubbery a clearance of 24" from the outdoor louver should be maintained.

For major obstructions such as a solid fence, wall or other heat rejecting device like a condensing unit, a minimum distance of 72" should be kept.

A.Ensure that the wall plenum is installed in accordance with the VPAWP1-8/1-14Installation Manual.

B.Ensure that the VPDP1 drain pan is installed correctly (see page 8). Using the 3/4" plugs supplied with the pan, plug the unused condensate drain hole. Connect a drain to the condensate exit location. Be sure to use teflon tape or approved pipe sealant on all drain connections and plugs (see page 8).

C.Place the chassis into the closet with the outdoor side facing the wall plenum opening.

D.Slide the chassis into the wall plenum until the plenum divider seal is established and the factory-installedchassis to plenum gasket has sealed to the top flange of the plenum. (See Figure 10)

Figure10

Each chassis is also equipped with a factory installed bellows that will drain water from the base pan to prevent the fan slinger from freezing during winter weather.

11)HeatingDefrost (HeatPumpModelsOnly)

All Heat Pumps have a passive heating defrost system. Defrost occursasneededandautomaticallyswitchestoelectricheatduring defrost.Whentheoutdoorambienttemperaturedropsbelowa45°F factory setting, the chassis automatically switches to electric heat. As outdoor ambient temperatures rise above 45°F, the chassis returns to the heat pump mode. The changeover temperature is user adjustable from approximately 32°F - 55°F. The defrost thermostat may also be used to lock out the compressor in an emergency heat situation.

12

920-159-01(10-03)

12)FreshAirDoor

The Fresh Air Door is an "intake" system. The fresh air door is opened via a slide on the front of the chassis located just above the indoor coil. Move the slide left to open and right to close the fresh air door. The system is capable of up to 60 CFM of fresh air @ ~.3" H20 internal static pressure.

13)CondensateDisposalSystem

The VPDP1 drain pan features two 3⁄4 female PVC fittings to attach a drain connection to on the left or right side of the drain pan. Condensate piping can be routed to the left, right or beneath

the unit platform.

See page 8 or the drain pan installation manual for more information.

Part 1: The system’s first stage increases energy efficiency utilizing a factory installed fan that slings the cold condensate onto the hot outdoor coil.

Part 2: When high outdoor humidity prevents the slinger from disposing of all the condensate, the excess condensate overflows into the condensate drain pan and out of the 3⁄4" internal drain connections.

Part 3: If Parts 1 & 2 fail for any reason, excess condensate overflows from a spillway directly into the wall plenum to the outside of the building.IF

THIS OCCURS, THIS IS YOUR WARNING THAT THE CHASSIS OR DRAIN NEEDS SERVICING.

14)Servicing/ChassisQuickChangeouts

The chassis is designed for quick disconnect and change out. For minor electrical service, the control box cover lifts straight up after the screws & disconnect head are removed. For major electrical, refrigeration and fan service the chassis may be removed from utility closet.

To Remove the Chassis from the Closet:

A.Switch the wall Thermostat off.

B.Pull the Power Disconnect located in the front of the chassis.

C.Disconnect the thermostat wiring harness.

D.Disconnect the electrical connection.

E.Disconnect the ductwork.

F.Slide the chassis out of the wall plenum.

G.Lift the chassis out of the utility closet.

15)RoutineMaintenance

PerformingRoutineMaintenance

With the proper maintenance and care, your system will operate economically and dependably. Maintenance can be accomplished easily by referring to the following directions. However, before performing any maintenance, consider these important safety precautions:

WARNING:ElectricalShockHazard.Beforeattemptinganyservice work or routine maintenance, turn off all electrical connections to the unit. Failure to do so may result in property damage, personal injury and/or death.

CAUTION: Although great care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit.

ReplaceAirFilter

A dirty air filter reduces the efficiency of your Vert-I-Pakand allows lint and dirt to accumulate on theindoor-aircoil. Lint and dirt on theindoor-aircoil can damage your unit and void the warranty. The air filter should be replaced as it becomes dirty.

To replace the filter (chassis mounted return air filter):

1.Slide the filter clear of the filter rails.

2.Remove the filter.

3.Install new disposable filter.

CAUTION: Do not operate your system without a filter in place, nor block the front of the unit return air opening.

InspectandCleanIndoor-airCoil

Eventually, minor amounts of lint and dirt may pass through the filter and collect on the indoor-aircoil. These minor accumulations can be carefully vacuumed away with a brush attachment on

a vacuum cleaner. Care must be taken to avoid bending the aluminum fins on the coil. Bent fins should be straightened using a special fin tool available from most HVAC service technicians.

InspectOutdoor-airIntakeandExhaust

The unit’s outdoor-airintake andoutdoor-airexhaust paths must remain clear. Check the OA exhaust frequently. Keep it free of all debris, snow, or ice. The OA intake should also be kept free of obstructions. Blocking the OA exhaust or OA intake opening will reduce the efficiency of your unit, could damage it, and may void your warranty.

InspectandCleanCondensateDrain

The condensate drain must be routed to a suitable drainage area. Check the unit condensate drain periodically. Keep it free of anything that may block or impede the flow of condensate water. If there is any accumulation of foreign matter in the drain pipe, it should be removed and cleaned. The entire drain line must be protected from freezing.
