3.0 UNIT INSTALLATION
CAUTION
This Condenser shipped without R22 charge. Instead the system is charged with
Nitrogen. The condenser is NOT to be activated until there is an R22 charge in the
system. The installer needs to release the nitrogen, vacuums to 350 microns, then
charges with R22 according to the charging chart on the installation manual.
3.1 LOCATION
Before starting the installation, select and check the suitability of the location for both
the indoor and outdoor unit. Observe all limitations and clearance requirements. The
outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air
discharge and for service access. See Fig.2
NOTE
For multiple unit installations, units must be spaced a minimum of 18 inches
apart. (Coil face to coil face.)
If the unit is to be installed on a hot sun exposed roof or a black-topped ground area, the
unit should be raised sufficiently above the roof or ground to avoid taking the accumulated layer of hot air into the outdoor unit.
Provide an adequate structural support.
3.2 GROUND INSTALLATION
The unit may be installed at ground level on a solid base that will not shift or settle, causing strain on the refrigerant lines and possible leaks. Maintain the clearances shown in
Fig.2 and install the unit in a level position.
Normal operating sound levels may be objectionable if the unit is placed directly under
windows of certain rooms (bedrooms, study, etc.).
Top of unit discharge area must be unrestricted for at least 60 inches above the unit.
WARNING
The outdoor unit should not be installed in an area where mud or ice could cause
personal injury or system damage.
Elevate the unit sufficiently to prevent any blockage of the air entrances by snow in
areas where there will be snow accumulation. Check the local weather bureau for the
expected snow accumulation in your area. Isolate the unit from rain gutters to avoid any
possible wash out of the foundation.
3.3 ROOF INSTALLATION
When installing units on a roof, the structure must be capable of supporting the total
weight of the unit, including a padded frame unit, rails, etc., which should be used to
minimize the transmission of sound or vibration into the conditioned space.

3.4 UNIT PLACEMENT
1.
2.
3.
4.
Provide a base in the pre-determined location.
Remove the shipping carton and inspect for possible damage.
Compressor tie-down nuts should remain tightened.
Position the unit on the base provided.
CAUTION
This system uses R22 refrigerant. No other refrigerant may be used in this
system. Gauge sets, hoses, refrigerant containers, and recovery system must be
designed to handle R22. If you are unsure, consult the equipment manufacturer.
The outdoor unit must be connected to the indoor coil using field supplied refrigerant
grade copper tubing that is internally clean and dry. Units should be installed only with
the tubing sizes for approved system combinations. The refrigerant charge shown in
the nameplate is for standard size interconnecting liquid line lengths up to 15 feet.
NOTE
Using a larger than specified line size could result in oil return problems. Using
a too small line will result in loss of capacity and other problems caused by insufficient refrigerant flow. Slope horizontal suction lines at least 1" every 20 feet
toward the outdoor unit to facilitate proper oil return.
3.5 UNIT MOUNTING
If elevating the heat pump, either on a flat roof or on a slab, observe the following guidelines.
1. The base pan provided elevates the heat pump 2” above the base pad.
2. If elevating a unit on a flat roof , use 4”× 4”(or equivalent) stringers
positioned to distribute unit weight evenly and prevent noise and vibration (See Fig.3).
NOTE:Do not block drain openings shown in Fig.3.
3. If unit must be elevated because of anticipated snow fall, secure unit and
elevating stand such that unit and/or stand will not tip over or fall off.

3.7 PRECAUTIONS DURING LINE INSTALLATION
1. Install the lines with as few bends as possible. Care must be taken not to damage
the couplings or kink the tubing. Use clean hard drawn copper tubing where no
appreciable amount of bending around obstruction is necessary, if soft copper must
be used, care must be taken to avoid sharp bends which may cause a restriction.
2. The lines should be installed so that they will not obstruct service access to the coil,
air handling system or filter.
3. Care must also be taken to isolate the refrigerant lines to minimize noise transmission from the equipment to the structure.
4. The suction line must be insulated. Tape and suspend the refrigerant lines as shown.
DO NOT allow tube metal-to-metal contact. See Fig.5.
5. Use PVC piping as a conduit for all underground installations as shown in Fig.6.
Buried lines should be kept as short as possible to minimize the build up of liquid
refrigerant in the suction line during long periods of shutdown.
6. Pack a sealing material such as perma gum around refrigerant lines where they
penetrate a wall to reduce vibration and to retain some flexibility.

3.8 PRECAUTIONS DURING BRAZING OF LINES
All outdoor unit and evaporator coil connections are copper-to-copper and should be
brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO
NOT use soft solder. The outdoor units have reusable service valves on both the liquid
and suction connections. The nitrogen charge is retained within the outdoor unit during
shipping and installation. The reusable service valves are provided to evacuate and
charge per this instruction.
Serious service problems can be avoided by taking adequate precautions to assure an
internally clean and dry system.
CAUTION
Dry nitrogen should always be supplied through the tubing while it is being
brazed, because the temperature required is high enough to cause oxidation
of the copper unless an inert atmosphere is provide. The flow of dry nitrogen
should continue until the joint has cooled. Always use a pressure regulator
and safety valve to insure that only low pressure dry nitrogen is introduced into
the tubing.Only a small flow is necessary to displace air and prevent oxidation.
3.9 PRECAUTIONS DURING BRAZING SERVICE VALVE
Precautions should be taken to prevent heat damage to service valve by wrapping a wet
rag around it as shown in Fig.8. Also, protect all painted surfaces, insulation, during
brazing. After brazing cool joint with wet rag.
The valve can be opened by removing the plunger cap and fully inserting a hex wrench
into the stem and backing out counter-clockwise until valve stem just touches the chamfered retaining wall.
11
Connect the refrigerant lines using the following procedure:
1. Remove the cap and Schrader core from both the liquid and suction service valve
service ports at the outdoor unit. Connect Iow pressure nitrogen to the liquid line
service port.

Fig.8 Heat Protection
2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure to wrap the valve
body with a wet rag. Allow the nitrogen to continue flowing. Refer to the Tabular Data
Sheet for proper liquid line sizing.
3. Carefully remove the rubber plugs from the evaporator liquid and suction connections
at the indoor coil.
4. Braze the liquid line to the evaporator liquid connection. Nitrogen should be flowing
through the evaporator coil.
5. Slide the plastic cap away from the suction connection at the indoor coil. Braze the
suction line to the evaporator suction connection. Refer to the Table 1 for proper
suction line sizing.
6. Protect the suction valve with a wet rag and braze the suction line connection to the
outdoor unit. The nitrogen flow should be exiting the system from the suction service
port connection. After this connection has cooled, remove the nitrogen source from
the liquid fitting service port.
7. Replace the Schrader core in the liquid and suction valves.
8. Leak test all refrigerant piping connections including the service port flare caps to be
sure they are leak tight. DO NOT OVER TIGHTEN (between 40 and 60 inch -lbs.
maximum).
9. Evacuate the suction line, evaporator, and the liquid line, to 350 microns or less.

5.0 EVACUATION
It will be necessary to evacuate the system to 350 microns or less. If a leak is
suspected, leak test with dry nitrogen to locate the leak. Repair the leak and test again.
To verify that the system has no leaks, simply close the valve to the vacuum pump
suction to isolate the pump and hold the system under vacuum. Watch the micron
gauge for a few minutes. If the micron gauge indicates a steady and continuous rise,
it's an indication of a leak. If the gauge shows a rise, then levels off after a few minutes
and remains fairly constant, its an indication that the system is leak free but still
contains moisture and may require further evacuation if the reading is above 350
microns.

7.0 SYSTEM OPERATION
7.1 COMPRESSOR CRANKCASE HEATER (CCH) (Heat pump only)
Refrigerant migration during the off cycle can result in a noisy start up. Add a crankcase heater to minimize refrigeration migration, and to help eliminate any start up
noise or bearing “wash out”.
All heaters must be located on the lower half of the compressor shell. Its purpose is to
drive refrigerant from the compressor shell during long off cycles, thus preventing
damage to the compressor during start-up.
The crankcase heating start condition:
1.The crankcase heating start must meet two conditions:
A. Outdoor temperature <37.4° F.
B. Compressor stops working more than 3 hours.
2. Outdoor temperature <37.4° F and just connected to the power source.
The crankcase heating stop must meet condition:
Outdoor temperature >44.6° F or compressor start.

7.3 PROTECTION FUNCTION INTRODUCTION (Heat pump only)
Sensor T3 (condenser pipe temperature) and T4 (outdoor ambient temperature)
When open-circuit, compressor, outdoor fan motor and reverse valve will be OFF.
T3>149°F,compressor stop working ; T3<140°F,compressor start working.
When T4 < 5 °F, compressor will stop.If the electrical heater kit is installed in the
indoor unit, the outdoor unit would provide a signal to drive up the heater.
When T4 > 10.4 °F, the compressor will restart.
Discharge temperature protection
When discharge temp. > 275 °F, the compressor will stop.
When discharge temp. < 194 °F, the compressor will restart.
High pressure protection
When high pressure is > 479 PSIG, the compressor and the outdoor fan motor will stop.
When high pressure is < 348 PSIG, the compressor and the outdoor fan motor will restart
(3 minutes delay necessary).
Low pressure protection
Low pressure is < 4.4 PSIG, the compressor and the outdoor fan motor will stop.
Low pressure is > 14.5 PSIG, the compressor and the outdoor fan motor will restart
(3 minutes delay necessary).
In stand-by status, the compressor will not start in low pressure protection.
Within 30 mins, if 4 protection cycles occurs.The system will be locked. It will
be restore after power cycle.
7.4 DEFROST MODE INTRODUCTION (Heat pump only)
Start-up conditions of defrost mode:
When JUMP switch is set to “1”(See in Fig 11), the mode will start up in either of
the two following conditions:
1. Compressor operating, when T4 is > 28.4 °F and T3 is < 32 °F last for 40 minutes;
2. Compressor operating, when T4 is < 28.4 °F and T3 is < 32 °F last for 50 minutes.
When JUMP switch is set to “0”:
Compressor operating, when T3 is < 32 °F last for 30 minutes.
Shut-down conditions of defrost mode:
The mode will shut down in either of the two following conditions:
1. The defrosted time lasting for 10 minutes;
2. T3 is ≥ 77 °F.

8.0 CHECKING REFRIGERANT CHARGE
Charge for all systems should be checked against the Charging Chart inside the
access corner panel or Charging by weight in 6.1.
IMPORTANT:Do not operate the compressor without charge in system. Addition of
R22 will raise pressures (suction, liquid and discharge).
8.1 CHARGING BY LIQUID PRESSURE
In order to properly charge the system, the following conditions must be met:
1) Outdoor temperature above 60°F.
2) Indoor temperature between 70°F to 100°F.
3)Installation must be complete with brazed joints and drier visually inspected.
4) The unit electrical installation must be checked and unit powered for one (I) hour if
crankcase heater is used or five (5) minutes if no crankcase heater is used.
Follow these steps:
1. Run in cooling mode at least 10 minutes.
2. Measure OUTDOOR AMBIENT TEMPERATURE within 6 inches of coil.
3. Measure SUCTION LINE PRESSURE.
4. Find the TARGET LIQUID PRESSURE at the intersection between the SUCTION
LINE PRESSURE and the OUTDOOR AMBIENT TEMPERATURE, if falls between
rows or columns then estimate the TARGET LIQUID PRESSURE or SUCTION LINE
PRESSURE falls between rows or columns then estimate the TARGET LIQUID
PRESSURE between the rows and columns.
5. Compare the measured LIQUID LINE PRESSURE to the TARGET LIQUID
PRESSURE, add charge to raise the pressure or recover charge to lower it.
6. After running unit for 10 minutes if the SUCTION LINE PRESSURE changes, go back
to step 2 otherwise remove test equipment and cover the valves.
8.2 CHARGING BY WEIGHT
For a new installation,evacuation of interconnecting tubing and indoor coil is adequate;
otherwise,evacuate the entire system. The refrigerant charge shown in the nameplate
is sufficient for 15 feet of standard size interconnecting liquid lines. Calculate actual
charge required with installed liquid line size and length,please see 6.1 of instruction.
With an accurate scale (+/- 1 oz.) adjust charge difference between that shown on
the unit data plate and that calculated for the new system Installation. if the entire
system has been evacuated, add the total calculated charge.
8.3 FINAL LEAK TESTING
After the unit has been properly evacuated and charged, a halogen leak detector
should be used to detect leaks in the system. All piping within the condensing unit,
evaporator, and interconnecting tubing should be checked for leaks. If a leak is
detected, the refrigerant should be recovered before repairing the leak. The Clean Air
Act prohibits releasing refrigerant into the atmosphere.
