INSTALLING & OPERATING
SETTING OF THE UNIT
• Unobstructed condenser air inlet and
discharge
• 10 inches minimum air clearance on all sides
• 18 inches clearance at the service access
• Unit to be mounted solid level foundation
• Make sure rooftop application can handle the
weight
ELECTRICAL SERVICE
• Unit rating plate will list electrical data
for proper size of electrical service
• Make owner familiar with location of the
over
• 18 gauge wire is needed for 24 volt
control wiring
REFRIGERANT TUBING
• USE ONLY REFRIGERANT GRADE COPPER
INDICATED IN TABLE 1
• SUCTION LINE INSULATION IS
NECESSARY TO
PRESENT
CONDENSATION
• 3/8 WALL THICKNESS OF ARMFLEX IS
SATISFACTORY
BRAZING THE LINE SET
• Tubing should be cut with a good tubing cutter
• Clean off any burrs
• Wrap a wet rag or use a thermal paste around a
service valve to prevent overheating
• Trickle a small amount of nitrogen through the
line set
• Braze with silver solder
LEAK TESTING
• Visually check all solder joints with an
inspection mirror
• Add a trace amount of R22 and then fill
line with 200 psig of dry nitrogen
• Test with soap bubbles or electronic
leak detector
• If there are no leaks vacuum line set to
500 microns and hold for 30 minutes
SYSTEM CHARGE
• System comes charged for 15 foot of
line set and matching evaporator
• Adjust the charge for every additional
foot of line set(see chart)
• Systems with over 50 foot line set may
require an oil charge adjustment
• Adjust the charge by the Superheat
Method (see video)
CLJ & CPLJ
Conversion To Scroll Compressors
Scroll Compressors should
never
be pumped down into a vacuum
.This could could cause internal
arching and cause the
compressor to fail.
Scroll Compressors do not
need
crank case heaters.

CAPACITORS
IT IS IMPORTANT TO KNOW THAT THE CAPACITOR IS PRODUCING THE CORRECT
EFFECT TO THE MOTOR CIRCUIT. TESTING THE CAPACITOR WITH A METER CAN
BE MISLEADING. THE METER PRODUCES 9 VOLTS TO THE CAPACITOR WHEN
TESTING THE MICRO-FARAD CAPACITY. THE CAPACITOR OPERATES WITH
GREATER THAN LINE VOLTAGE APPLIED. THE START WINDING PRODUCES WHAT
WE CALL COUNTER EMF [ELECTROMOTIVE FORCE]. THE CAPACITOR CAN BE
TESTED WHILE OPERATING BY READING THE VOLTAGE APPLIED AND THE
AMPERAGE TO THE START WINDING OF THE MOTOR. ONCE THOSE READINGS ARE
TAKEN, THE TECH CAN APPLY THEM TO THIS FORMULA.

A WEAK CAPACITOR CAN CAUSE THE
COMPRESSOR TO OVERHEAT
CAUSING A HIGH DISCHARGE
TEMPERATURE WHICH GETS US
BACK TO THE BREAKDOWN OF THE
LUBRICANT.
INSTALLATION
LOCATION
• 10 TO 12 INCHES FROM WALLS OR OBSTRUCTIONS
• IF THERE IS AN OVERHANG….. SHOULD BE AT LEAST 36 INCHES
CLEARANCE
• UNIT IS TO BE MOUNTED ON A SOLID, LEVEL FOUNDATIONS
ELECTRICAL
• ALL WIRING MUST BEIN ACCORDANCE WITH THE NATIONAL
ELECTRICAL
CODE
• RATING PLATE ON THE CONDENSING UNIT LISTS ELECTRICAL
DATA NECESSARY FOR THE SELECTION OF PROPER SIZE
ELECTRICAL SERVICE AND OVER-CURRENT PROTECTION
• CONTROL WIRING REQUIRES A 24 VOLT MINIMUM 25 VA SERVICE
FROM THE INDOOR TRANSFORMER ……………...
18 GAUGE
WIRE MUST BE USED
TEMPERTURE RISE METHOD
CFM = KW x 3413
TEMPERATURE RISE x 1.08
where :
KW = The indoor section's measured input power =
Volts x Amps
and :
Volts = The measured Volts at the Indoor Section
Amps = The measured Amps at the indoor Section
Temp. Rise = The temperature of the supply air minus the temperature of the
return air
3413 = BTU per KW
1.08 = specific heat air constant
e.g. :
The input power to the indoor section = 10 KW
The Temperature Rise = 20o F
CFM = 10 x 3413 = 1580
TEMPERTURE SPLIT
Verifying proper air flow
 Set thermostat to emergency heat
mode. Call for heat.
 Measure DT @ indoor coil
 Measure Electric Heat volts & amps
 BTU = Watts (Volts X Amps) X 3.413
 CFM = BTU / (DT X 1.08)

Normal Operation
Outdoor Thermostat Mode
Control Environment
Primary Functions
• Interface Between a Heat Pump
Thermostat and a Heat Pump
and a Fossil Fuel Furnace
• Option for an Outdoor
Thermostat
• Compressor Short Cycling
Prevention
Normal Operation
• 1st Stage Cooling from Thermostat
Operates the Heat Pump Compressor
• 2nd Stage Cooling or an Emergency
Heat Call Operates the Fossil Fuel
Furnace & Disables Compressor
• Timer Prevents Compressor from
Operating for 120 Seconds from DeActivation
Control Inputs
• “R” - Source is Furnace “R” Terminal
– Distributes “R” to Heat Pump & Thermostat
• “C” - 24VAC Common ; Source is Furnace
– Distributes “C” to Heat Pump & Thermostat
• “O” - Reversing Valve Routed to Heat Pump
• “E”- Emergency drops out heat pump via
K2 contact energizing W2 gas furnace heat
• “W2”- 2nd Stage Call for Heat
– Identical to Emergency Heat ; Connected to Same on
Control
Control Outputs
• Furnace “W” - Heat Pump “W2/OT-NO”
• Furnace “G” - T-Stat Input for High Speed
Fan
• Heat Pump “O” - Reversing Valve Output
• Heat Pump “Y” - Heat Pump Compressor
Call
Control Outputs Continued...
• Heat Pump “OT-NC” - Connects to Heat
Pump “Y” thru N.C. Relay K2 and N.O.
Relay K3
– Determines if Heat Pump Will Run When “Y” Call is
Received from Thermostat
• “OT-C” - Common Terminal for Outdoor
Thermostat
– “BREAK FOR ODT” Tab must be removed
Outdoor Thermostat
Mode
• Provision for SPDT Outdoor Thermostat
• Outdoor Thermostat Must be Connected to
the OT-NC & OT-C Terminals
• Determines Whether Heat Pump or
Furnace will Run in 1st Stage Heating.
• The “BREAK FOR ODT” Must be Removed
Before Connecting the Outdoor Thermostat
