frontcenter of the unit. Refer toTable 4and Table5for required circuits and recommended wiresizefor each circuit.
DANGER: Electrical shock hazard. Turn OFF electric power at the fuse box or service panel before making any
electrical connections and ensure a proper ground connection is made before connecting line voltage. Failure to do
so can result in property damage, personal injury and/or death.
Unit Wiring with VPDB1 Distribution Block
1If wire is applied at ambient greater than 30°C (86°F), consult Table 310-16 of the NEC (ANSI/NFPA 70). The ampacity of nonmetalic-sheathed
cable (NM), trade name ROMEX, shall be that of 60°C (140°F) conductors, per the NEC (ANSI/NFPA 70) Article 336-30. If other than uncoated (non-
plated), 60°C or 75°C (140°F or 167°F) insulation, copper wire (solid wire for 10 AWG and smaller, stranded wire for larger than 10 AWG) is used,

B. Thermostat Mounting and Wiring
The thermostat is a precision instrument and was carefully adjusted at the factory. Handle it carefully.
CAUTION: Disconnectthe powersupply before beginning installationof the thermostat to preventelectrical shock
or equipment damage. Do not short across the thermostat terminals. This can burn out the thermostat anticipator.
All wiring for the thermostat circuit must comply with NEC, state and local codes. Use No. 20 AWG color-coded,
insulated (35°C minimum) wire. If the thermostat is located more than 100 ft. from the unit (as measured along the
controlvoltagewires), use No. 18 AWG color-coded wires to avoid excessive voltagedrop.
1. In replacement applications, check the existing thermostat wiring for cracked or frayed insulation. Replace any
wiring in poor condition. All wiring must comply with local codes and ordinances.
2. Run wiring (if necessary) to the location. Thread the wires through a hole in the packing material saved in Step 2.
Connect the wires to the terminals on the back of the thermostat. (See Figure 11.)
3. Push the excess wire back through the hole and plug any opening with packing material to prevent drafts that may
affectthermostat performance.
4. Loosely secure the thermostat to the wall with screws through the two mounting holes in the middle of the thermo-
stat.
5. Level the thermostat. Tighten the two mounting screws.
6. Replacethe thermostat cover.

NOTE: If the unit is to be installed in an attic or furred space where damage may result from condensate overflow, it may
benecessary to provide a field-suppliedsecondary drainpan. Alwaysrefer to local and nationalcodes.
Test Run
Test run in Heating, Cooling, and Emergency Heat mode as follows:
a. Set fan control to ON. If fan runs, return control to AUTO setting. This verifies fan is working properly.
b. Set system control from OFF to COOL. Lower temperature selector to 50°F or lower. The compressor should
energizeandcoolair should flow from room registers. Once cooling test is complete, return system controltoOFF
setting. Wait 5 minutes.
c. Set system control to HEAT and raise temperature selector to 80°F or higher. Compressor should energize, and
warm air should flow from room registers.
d. Set system control to EM HEAT (Emergency Heat). Compressor should turn off and warm air should continue to
flow from the registers. (This step is for heat pumps only.)
NOTE: During EM HEAT operation, temperature of air flowing from room registers may be slightly warmer than
during normal HEAT mode operation.
Leave both Installation Manual and Users Manual with owner or user of equipment.
After 72 hours of operation, the unit will achieve full rated operating performance.

IDENTIFYING YOUR SYSTEM
Take the time to familiarize yourself with the type of system you have. This knowledge will be of use in understanding the
basic operation of your unit.
Aself-containedunit,liketheVert-I-Pak,hasallofitsmajorcomponentsinonecabinetlocatedinsideyourhome. Theunit
does not have a separate outdoor unit like a traditional “split-system”air conditioner or heat pump. Figure 4 shows the
location of the major components inside the cabinet.
Theproductmodelandratingdatalabelisaffixedtotheunitfrontpanelandprovidesthenecessaryinformationforspecific
identification of the unit. You should familiarize yourself with the model and serial numbers listed on the label.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts:
Your system should never be operated without a clean air filter properly installed. A dirty, clogged air filter will increase
operating costs and shorten the life of the unit. The air filter should be replaced as it becomes dirty.
Supply-air and return-air registers should not be blocked. Restricted airflow reduces the efficiency and life span of your
unit.
For your system to function properly, it MUST have a constant supply of outdoor air to the outdoor air coil located inside
theunit.Theoutdoor-airintakeandexhaustopeningsarelocatedonthebacksideoftheunit. Familiarizeyourselfwiththe
outside air openings on the building and check to ensure that they are not obstructed.
Thermostat
Yourmultipurposeindoor thermostat is the control center for your comfort system.You should familiarizeyourself with its
properoperation.Attemptingtocontrolthesystembyothermeans–forinstance,switchingtheelectricalsupplypowerON
and OFF –may cause damage to the unit.
With some thermostats, increasing the HEAT mode temperature set point more than 2°F may cause the auxiliary electric
heaters to operate to satisfy the call for heating. To minimize energy costs, do not increase the HEAT mode temperature
set point by more than 2°F at a time.
Depending on the design of your home and its ventilation ductwork and registers, areas of warm or cool air may develop
throughout the home. Operating the unit with the fan switch “ON”increases air mixing throughout the home and reduces
temperature variations within the home.
Dehumidification
Duringthecoolingseason,theVert-I-Pakalsodehumidifiestheairinthehomewhileisitcoolingtheair.Afterafewminutes
of operation, water should run freely from the condensate drain line extended to the outside of your home. If condensate
isnotrunningfromthedrainline,checktobesurethatthedrainhoseorpipeisproperlyconnectedtothedrainfittinglocated
on the bottom of the unit which is accessible from beneath the home. Check the drain line periodically during the cooling
seasonto ensure the condensate is running freelyfrom outside thehome anddraining awayfrom thehome’s foundation.
(Note: in lower humidity climates, the indoor air may be too dry to generate condensate during the cooling mode.)
Heat Pump
If you are a first-time owner of an all-electric heat pump, the operating characteristics of the system may be different than
you are accustomed to as compared to conventional electric resistance, gas or oil furnaces. Air entering a conventional
furnaceat60°Fmay bewarmed 60°to100°F.Thesupplyair leavingthe registerswould thenbebetween120°and160°F
depending on the system. A heat pump warms the same 60°F air 20°to 30°F. The supply air leaving the registers would
then be between 80°and 90°F. This air may feel cool because it is slightly less than your body temperature. However, it

Thetemperature controlis aselectoror setof buttonsthatallows youto establishthedegree oftemperature thatyouwish
to maintain for your personal comfort. Some thermostats have two temperature control selectors: one for setting the
temperature desired during the cooling cycle, and one for setting the heating operation temperature.
Typical settings are 78°F for cooling and 68°F for heating.
Fan Control
The FAN control offers two options for controlling the indoor-air blower: AUTO and ON. When the FAN control is set to
AUTO,theblowerwilloperateonlywhilethethermostatoperatesthecoolingorheatingequipment.WhentheFANcontrol
is set to ON, the blower will operate continuously –regardless of whether cooling or heating equipment is operating. This
setting allows for continuous air circulation and filtration.
