SINGLE PACKAGE AIR CONDITIONER
GAS/ELECTRIC

Congratulations . . .
On your purchase of our Single Package Air Conditioning Unit. This energy efficient unit has been precision designed,
manufactured of high quality materials and has passed many rigorous inspections and tests to ensure years of satisfactory
service.
This manual is meant to increase your understanding of your system, tells you how to operate it efficiently and how to obtain
the greatest measure of comfort at the lowest operating expense. Please read this manual thoroughly.
We appreciate your interest in our products and your decision to purchase our Single Package Unit. Enjoy your comfort.

This gas/electric, heating/cooling
unit is designed for outdoor use and
can be installed anywhere from
grade level to the roof. Electric air
conditing in the summer and gas
heating in the winter - all from a
single unit.

SYSTEM OPERATION
THERMOSTATS
Set your thermostat for either
heating or cooling then set it for the
desired temperature. DO NOT
MOVE THE THERMOSTAT RAPIDLY ON AND OFF, OR BACK AND
FORTH FROM HEAT TO COOL.
THIS COULD DAMAGE YOUR
EQUIPMENT.
Always allow at least 5 minutes
between changes. Find the temperature that is most comfortable to
you, and then LEAVE YOUR
THERMOSTAT ALONE. (Exception
is for night or vacation "set back" to
conserve energy)
Manually moving the thermostat
up or down will not speed up temperature changes in your rooms.
This only causes the thermostat
switch to function at your command
rather than responding to room temperature.
Heat generated by devices other
than the furnace may interfere with
thermostat performance. Therefore,
lamps, radios, television sets, etc.
should not be placed near the
thermostat.
HOT SURFACE PILOT
IGNITION DEVICE
This unit is equipped with a hot
surface pilot ignition device. The
control is designed to automatically
light the burner each time the
thermostat "calls" for heat.

CAUTION: Do not attempt to
manually light the burners. Personal injury could result

2

HEATING
When the thermostat calls for
"HEAT", the thermostat energizes
the combustion air blower.
After airflow is established, the air
proving switch closes, the hot surface ignitor is energized and the pilot
valve opens igniting the pilot flame.
The flame rod senses a flame and
de-energizes the ignitor opening the
main gas valve and the main burners light.
30 seconds after the main burners
light the circulating fan is energized
at the heating speed.
When the thermostat is satisfied,
the ignition system is de-energized
closing the gas valve.
After a 5 second postpurge timing
period, the combustion air blower is
de-energized and the heat fan off
timing begins.
When this field selected heat fan
off timing is completed the circulating fan is de-energized.
If the primary, rollout and auxiliary
limit switches open, the thermostat
and ignition system is de-energized
and the gas valve closes. The combustion blower and the circulating
fan, at heat speed, are energized.
The combustion blower remains
energized for the 5 second postpurge timing period if the primary,
rollout and auxiliary limit switches
remake the contact (the rollout and
auxiliary limit switches must be
manually reset). The circulating fan
remains energized for the selected
heat delay off timing.
Normal operation of the system
resumes.

COOLING
When the thermostat calls for
"COOL", the thermostat signals the
compressor and outdoor fan to run.
After a cool fan on delay timing of
2 seconds, the circulating fan is energized at cooling speed.
When the thermostat is satisfied,
the compressor and outdoor fan is
de-energized,
After a cool fan off delay timing of
30 seconds the circulating fan is deenergized.
CIRCULATING FAN
When the thermostat calls for
"FAN", the thermostat terminal signals the circulating fan to run at the
heat speed 2 seconds after the
thermostat is energized.
If a call for "HEAT" occurs, the
circulating fan continues to run at
the heat speed.
If a call for "COOL" occurs, the
circulating fan switches to cool
speed after a 4 second delay.
When the thermostat ends the call
for "FAN", the thermostat is de-energized, de-energizing the circulating fan.
INPUT
The correct heat capacity of the
furnace is regulated by the burner
orifices and the gas pressure. The
proper orifices are furnished but the
gas pressure regulator must be adjusted by the installing serviceman
or gas company. This is a "one-time"
adjustment.

WARNING: Should overheating occur, shut off the manual
gas valve external to the appliance before shutting off the
electrical supply.

PROPER CARE OF
YOUR SYSTEM

Filters should be checked monthly
especially since this unit is used for
both heating and cooling.

CAUTION: Prior to any of the
following maintenance procedures, shut off all power to the
unit.

REGISTERS
Supply air and return air registers
must be open when the unit is in
operation. Furniture must not block
airflow in or out of the registers.

LUBRICATION
The indoor blower motor, outdoor fan
motor and ventor motor are permanently lubricated and require no maintenance.

COIL CARE
An annual check and cleaning, if
necessary, of the condenser coil
should be done. Clean any debris
and dirt from the outside coil face
with a brush being careful not to
damage the fins. If extremely dirty,
a hose can be used to wash the coil
from the inside out while brushing a
soapy solution on the outside.

GENERAL MAINTENANCE
The manufacture recommends
that the furnace system be inspected once a year by a qualified
service person.
For proper and safe operation, the
gas heating section needs air for combustion and ventilation. Do not block or
obstruct air openings on the unit, nor
the spacing around the unit. Keep the
gas heating system area clear and free
of combustible materials, gasoline and
other flammable vapors and liquids.
Snow or debris should not be allowed to accumulate in or around
the unit. Do not permit overhanging
structures or shrubs to obstruct condenser air discharge or vent outlet
on your unit. These provide air for
combustion and ventilation.
FILTER CARE
Single phase units are shipped
without a filter and is the responsibility of the installer to secure a filter
in the return air ductwork or install
a Filter/Frame Kit (1FF0110).
A filter rack and a high velocity
filters are standard on three phase
units.
Filters must always be used and
must be kept clean. When filters become dirt laden, insufficient air will be
delivered by the blower, decreasing
your units efficiency and increasing
operating costs and wear-and-tear on
the unit and controls.

TROUBLESHOOTING
BEFORE CALLING A SERVICEMAN:
A. Check thermostat setting and
insure thermostat is calling for
heat or cooling.
B. Check thermostat for lint, dust, etc.
C. Check fuses or circuit breakers.
D. Check filters for excessive dust
accumulation and/or restriction.

PARTS INFORMATION
UPG renewal parts may be obtained from your local qualified UPG
contractor-check the yellow pages
in your telephone directory.

SOME EFFICIENCY
DO’S AND DON’TS
DON’T heat or cool unused areas.
Reduce supply and return air flow to
a minimum in areas which are not
living spaces (storage rooms, garaged, basements, etc.).
DON’T be a "thermostat jiggler".
Moving your thermostat setting will
not make your system heat or cool
any faster. Adjust your thermostat to a
comfortable setting and leave it there.

DON’T restrict air circulation. Placing furniture, rugs, etc. in such a way
that they interfere with air vents will
make your system work harder to
achieve a comfortable temperature
level. This requires more energy,
which means greater cost to you.
DON’T heat or cool when you are
away. If you are going to be away for
a day or more, re-adjust your thermostat accordingly. Your furniture is far
less demanding than you are when it
comes to comfort levels. However,
don’t expect the system to restore
comfort conditions immediately upon
returning home. It will take a little time.
DON’T locate lamps or other heatproducing appliances (radios, TV’s,
heaters, etc.) near your thermostat.
The heat from these items will give
your thermostat "false information"
about the temperature in the room.
DO select a comfortable thermostat setting, but keep in mind that
moderation in temperature selection
will save energy.
DO turn on your kitchen exhaust fan
when cooking and your bathroom exhaust fan when showering. Also, make
sure your clothes dryer is properly
vented. If these items are neglected, an
excess heat and humidity condition
may be created, causing your air conditioning system to run longer.
DO set your thermostat a few degrees lower than normal several hours
before entertaining a large group of
people in a relatively small area. People give off a considerable amount of
heat and moisture in a closed area.
DO keep drapes and Venetian
blinds closed when practical. These
items provide insulation against
heat loss/gain.
DO contact a qualified service
man to make repairs or adjustments
to your system. He has been trained
to perform this service.
