that will not shift or settle. To reduce the possibility of sound transmission, the foundation slab should not be in contact with or be an integral part of the building foundation. Care should be taken to ensure the unit is installed away from noise sensitive locations such as bedrooms, windows and outdoor living areas. Ensure the foundation is sufficient to support the unit. A concrete slab raised above ground level provides a suitable base.

OOFTOP INST ALLATIONS

If it is necessary to install this unit on a roof structure, ensure the roof structure can support the weight and that proper consideration is given to the weather-tight integrity of the roof. Since the unit can vibrate during operation, sound vibration transmission should be considered when installing the unit. Vibration absorbing pads or springs can be installed between the heat pump unit legs or frame and the roof mounting assembly to reduce noise vibration.

ELECTRICAL NOISE

The unit should be well grounded so that potential effects of electrical noise from the inverter to surrounding equipment can be minimized.

When selecting an installation location, keep sufficient distance from the heat pump unit and wiring to radios, personal computers, stereos, etc., as shown in the following figure.

UNITS IS EXTREMELY

Use only refrigerant grade (dehydrated and sealed) copper tubing to connect the heat pump unit with the indoor unit. After cutting the tubing, install plugs to keep refrigerant tubing clean and dry prior to and during installation. Tubing should always be cut square keeping ends round and free from burrs. Clean the tubing to prevent contamination. The liquid line must be insulated if more than 50 ft. of liquid line will pass through an area that may reach temperatures of 30 °F or higher than ambient in cooling

Page 4

mode and/or if the temperature inside the conditioned space may reach a temperature lower than ambient in heating mode. Never attach a liquid line to any uninsulated potion of the gas line.

Do NOT let refrigerant lines come in direct contact with plumbing, ductwork, floor joists, wall studs, floors, and walls. When running refrigerant lines through a foundation or wall, openings should allow for sound and vibration absorbing material to be placed or installed between tubing and foundation. Any gap between foundation or wall and refrigerant lines should be filled with a pliable silicon-based caulk, RTV or a vibration damping material. Avoid suspending refrigerant tubing from joists and studs with rigid wire or straps that would come in contact with the tubing. Use an insulated or suspension type hanger. Keep both lines separate and always insulate the gas line.

Heat Pump BEL OW Indoor Coil

Insulation is necessary to prevent condensation from forming and dropping from the gas line. Armflex or satisfactory equivalent with 3/8” min. wall thickness is recommended. In severe conditions (hot, high humidity areas) 1/2” insulation may be required. Insulation must be installed in a manner which protects tubing and connections from damage and contamination.

Where possible, drain as much residual compressor oil from existing systems, lines, and traps; pay close attention to low areas

where oil may collect. NOTE: If changing refrigerant, the indoor

coil and metering device must be replaced. Only AV**PVC air handlers or TXV** expansion valves are compatible and have been manufacturer approved for use with these models. See unit specifications or AHRI for an approved system match.

IMPORT ANT

To avoid overheating the service valve, TXV or filter drier while brazing, wrap the component with a wet rag, or use a thermal heat trap compound. Be sure to follow the manufacturer’s instruction when using the heat trap compound. Note: Remove Schrader valves from service valves before brazing tubes to the valves. Use a brazing alloy of 2% minimum silver content. Do not use flux.

Torch heat required to braze tubes of various sizes is proportional to the size of the tube. Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed.

NOTE: The use of a heat shield when brazing is recommended

to avoid burning the serial plate or the finish on the unit.

1. The ends of the refrigerant lines must be cut square, deburred, cleaned, and be round and free from nicks or dents. Any other condition increases the chance of a refrigerant leak.

2. “Sweep” the refrigerant line with nitrogen or inert gas during brazing to prevent the formation of copper-oxide inside the refrigerant lines. The FVC oils used in R-410A applications will clean any copper-oxide present from the inside of the refrigerant lines and spread it throughout the system. This may cause a blockage or failure of the metering device.

3. After brazing, quench the joints with water or a wet cloth to prevent overheating of the service valve.

4. A bi-flow filter drier is shipped with the unit as a separate component and must be brazed on by the installer onsite. Ensure the bi-flow filter drier paint finish is intact after brazing. If the paint of the steel filter drier has been burned or chipped, repaint or treat with a rust preventative.

The recommended location of the filter drier is before the expansion device at the indoor unit.

WARNING

AVOID THE RISK OF FIRE OR EXPLOSION, NEVER USE OXYGEN, HIGH PRESSURE AIR OR FLAMMABLE GASES FOR LEAK TESTING OF A REFRIGERATION SYSTEM

PSIG

To locate leaks, pressure test the system using dry nitrogen or leak detector fluid per the manufacturer’s recommendation. If you wish to use a leak detector, charge the system to 10 psi using the appropriate refrigerant then use nitrogen to finish charging the system to working pressure then apply the detector to suspect areas. If leaks are found, repair them. After repair, re-

peat the pressure test. If no leaks exist, proceed to System Start-

up Procedure.

YSTEM START-UP PROCEDURE

1. Connect the vacuum pump with 250 micron capability to the service valves.

2. Evacuate the system to 250 microns or less using gas and

liquid service valves. Using both valves is necessary as some compressors create a mechanical seal separating the sides of the system.

3. Close pump valve and hold vacuum for 10 minutes. Typically pressure will rise during this period.

• If the pressure rises to 1000 microns or less and remains steady the system is considered leak-free; proceed to start-up.

• If pressure rises above 1000 microns but holds steady below 2000 microns, moisture and/or noncondensibles may be present or the system may have a small leak. Return to step 2: If the same result is encountered check for leaks as previously indicated and repair as necessary then repeat evacuation.

• If pressure rises above 2000 microns, a leak is present. Check for leaks as previously indicated and repair as necessary then repeat evacuation.

ATTENTION INSTALLER - IMPORTANT NOTICE!

Please read carefully before installing this unit.

When opening valves with retainers, open each valve only until the top of the stem is 1/8” from the retainer. To avoid loss of refrigerant, DO NOT apply pressure to the retainer. When opening valves without a retainer, remove service valve cap and insert a hex wrench into the valve stem and back out the stem by turning the hex wrench counterclockwise. Open the valve until it contacts the rolled lip of the valve body.

NOTE: Units may utilize ball valves or front seating valves. These

are not back-seating valves. It is not necessary to force the stem tightly against the rolled lip.

After the refrigerant charge has bled into the system, open the liquid service valve. The service valve cap is the secondary seal for the valves and must be properly tightened to prevent leaks. Make sure cap is clean and apply refrigerant oil to threads and sealing surface on inside of cap. Tighten cap finger-tight and then tighten additional 1/6 of a turn to properly seat the sealing surfaces.

Do not introduce liquid refrigerant from the cylinder into the crankcase of the compressor as this may damage the compressor.

Break vacuum by fully opening liquid and gas base valve.

• For AVZC20, do not install the 24 Volt Transformer that is included with the CTK04 Thermostat in the Heat Pump Unit; it is not needed.

3. Convert the liquid pressure to temperature using a temperature/pressure chart.

4. Temporarily install a thermometer on the liquid line at the liquid line service valve.

a. Ensure the thermometer makes adequate contact and is insulated for best possible readings.

5. Subtract the liquid line temperature from the converted liquid pressure to determine subcooling.

6. Before starting the Subcooling adjustment, make sure the outdoor ambient temperature is in a below range and the unit is operating at 100% capacity.

SUBCOOLING = (SA T. LIQUID TEMP .) - (LIQUID LINE TEMP.)

SUPERHEA T = ( SUCT. LINE TEMP .) - (S AT . SUCT. TEMP .)

e. If subcooling and superheat are high, adjust the TXV

valve to 7 to 9°F superheat, then check subcooling.

f. If subcooling is high and superheat is 7 to 9°F, remove

charge to lower the subcooling to 7 to 9°F, then check superheat.

g. If subcooling is high and superheat is low, adjust the

TXV valve to 7 to 9°F superheat and remove charge to low the subcooling to 7 to 9°F.

h. If subcooling is 7 to 9°F and superheat is low, adjust the

TXV valve to 7 to 9°F superheat and remove charge to lower the subcooling 7 to 9°F, then check the superheat.

DEHUMIDIFICATION

The thermostat reads the indoor humidity level from the CTK04 and allows the user to set a dehumidification target based on these settings. The thermostat controls the humidity level of the conditioned space using the cooling system. Dehumidification is engaged whenever a cooling demand is present and structural humidity levels are above the target level. When this condition exists, the circulating fan output is reduced, increasing system run time, over cooling the evaporator coil and ultimately removing more humidity from the structure than if only in cooling mode. The CTK04 also allows for an additional overcooling limit setting from 0°F to 3°F setup through the Installer Option menu (directions following). This allows the cooling system to further reduce humidity by lowering the temperature up to 3°F below the cooling setpoint in an attempt to better achieve desired humidity levels.

By default, dehumidification needs to be turned ON at the thermostat via the Dehumidification Equipment menu. Dehumidification can be activated at the original equipment setup by selecting the A/C with Low Speed Fan button in the Dehumidification Menu. Availability can be verified by pressing MENU on the home screen. Scroll down and if a Dehumidification button is present, dehumidification is activated.

If Dehumidification is not available in the menu then it must be enabled through the Installer Options menu. Use the following procedure to enable and disable dehumidification:

1. On the CTK04 HOME screen select MENU.

2. From the MENU screen, scroll down and select Installer Options.

3. Enter installer password if known.

a. The password is the thermostat date code and can

be obtained by selecting the red Cancel button and selecting the Dealer Information button.

b. Once recorded, click the green OK button and re-

turn to the previous step.

4. Select YES to continue.

5. Select View / Edit Current Setup.

6. Scroll down and select Dehumidification.

7. Once open select Dehumidification Equipment: None.

8. From the Dehumidification Menu select A/C with Low Speed Fan and click the green Done button.

9. Additional Dehumidification operational options can be selected in the resulting window.

10. Once satisfied with the selection, navigate to the HOME screen by selecting the Done button and selecting Yes to verify the changes.

11. Select Previous Menu, then the HOME to return to the main menu.

DEHUMIDIFICATION TIPS

For effective dehumidification operation:

• Ensure “Dehum” is ON through the Installer Options menu and/or in the ComfortNet User Menu (COOL SETUP).

- If ON, the Dehumidification menu should be visible in

the main menu.

• Verify the cooling airflow profile is set to “Profile D”.

- See the Cool Set-up section of the Installation Manual

for complete airflow profile details.

- By default, “Dehum” is ON and the cooling airflow pro-

file is set to “Profile D”.

• For additional dehumidification control, airflow settings are field adjustable and can be fine-tuned to a value that is comfortable for the application from a range of +15% to -15%.

- See the Heat Pump Advanced Feature Menu section

of the Installation Manual for more detail.

COMFORTNET™ SYSTEM

OVERVIEW

A ComfortNet inverter heating and air conditioning system uses an indoor unit, outdoor unit and thermostat which digitally communicate with one another via a two-way communications path. The thermostat sends commands to the indoor and outdoor units. The thermostat may request and receive information from both the indoor and outdoor units. This information may be displayed on the CTK04 thermostat. The indoor and outdoor units also interact with one another. The outdoor unit may send commands to or request information from the indoor unit. This twoway digital communications between the thermostat and subsystems (indoor/outdoor unit) and between subsystems is the key to unlocking the benefits and features of the ComfortNet system.

Two-way digital communications is accomplished using only two wires. The thermostat needs 24 VAC for power. 4 wires between the indoor unit and thermostat plus two wires between the indoor unit and outdoor unit are all that are required to operate the system.

COMFORTNET SYSTEM ADVANCED FEATURES

The ComfortNet™ system permits access to additional system information, advanced set-up features, and advanced diagnostic/troubleshooting features. These advanced features are orga-

nized into a menu structure. See the HEAT PUMP ADVANCED FEATURES MENU section for the menu layout.

DIRECTIONS TO HEAT PUMP ADVANCED FEATURE MENUS

Press MENU, scroll down and press COMFORTNET USER MENU.

Enter the date code (password) when prompted. The date code is

printed on the back of the thermostat; or press MENU > EQUIP- MENT STATUS and scroll down to find the date code. After you

enter the password, select COMFORTNET USER MENU, answer YES to the following menu and select HEAT PUMP to view the system menus.

DIAGNOSTICS

The heat pump’s diagnostics menu provides access to the most recent faults. The six most recent faults are displayed on the first screen. Six additional faults are displayed under fault history. Faults are stored in order from most recent to least recent. Any consecutively repeated fault is stored a maximum of three times. Example: A leak in the system, low refrigerant charge or an incompletely open stop valve can cause the unit to flash error code E15. This error code suggests that the unit is experiencing operation at low pressure. The control will only store this fault the first three

consecutive times the fault occurs. NOTE: It is highly recommended that the fault list be cleared after

performing maintenance or servicing the system.

TROUBLESHOOTING

NETWORK TROUBLESHOOTING

Communications is achieved by taking the difference between a positive dc signal and a negative dc signal. The positive dc signal is termed “data 1” or “1’. Data 1 is positive with respect to ground (or common). The negative dc signal is termed “data 2” or “2”. Data 2 is negative with respect to ground (or common).

Data 1 should be approximately 2.8 volts dc. Data 2 should be approximately 2.2 volts dc. The voltage difference between data 1 and data 2 should be approximately 0.6 volts dc.

Verify that the bus DS1 dip switches are in the ON position.

SPLIT SYSTEMS

AIR CONDITIONING AND HEA T PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS

We strongly recommend a bi-annual maintenance checkup be performed

before the heating and cooling seasons begin by a qualified servicer.

REPLACE OR CLEAN FILTER

IMPORT ANT NOTE: Never operate unit without a filter installed as

dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.

An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.

Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.

Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced. Reusable type filters may be cleaned.

You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types. These filters can do a better job of catching small airborne particles.

COMPRESSOR

The compressor motor is hermetically sealed and does not require additional oiling.

MOT ORS

Indoor and outdoor fan motors are permanently lubricated and do not require additional oiling.

CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)

Air must be able to flow through the outdoor unit of your comfort system. Do not construct a fence near the unit or build a deck or patio over the unit without first discussing your plans with your dealer or other qualified servicer. Restricted airflow could lead to poor operation and/or severe equipment damage.

Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or debris could also restrict the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could easily puncture the tubing in the coil. Even a small hole in the tubing could eventually cause a large loss of refrigerant. Loss of refrigerant can cause poor operation and/or severe equipment damage.

Do not use a condensing unit cover to “protect” the outdoor unit during the winter, unless you first discuss it with your dealer. Any cover used must include “breathable” fabric to avoid moisture buildup.

BEFORE CALLING YOUR SERVICER

• Check the thermostat to confirm that it is properly set.

• Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor operation for awhile, and then reset automatically. Also, some power companies will install devices which shut off air conditioners for several minutes on hot days. If you wait several minutes, the unit may begin operation on its own.

AVOID THE RISK OF EQUIPMENT DAMAGE OR FIRE, INSTALL

SAME AMPERAGE BREAKER OR FUSE AS YOU ARE

THE REPLACING AGAIN TO

F YOU REPEATEDLY RESET THE BREAKER OR REPLACE

THE YOU RUN THE RISK OF SEVERE EQUIPMENT DAMAGE

. IF

WITHIN THIRTY DAYS, CONTACT A QUALIFIED SERVICER

CORRECT THE PROBLEM

FUSE WITHOUT HAVING THE PROBLEM CORRECTED

THE CIRCUIT BREAKER OR FUSE SHOULD OPEN

• Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.

• Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.

• Check for obstructions on the outdoor unit . Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.

• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains or furniture).

• Check the filter. If it is dirty, clean or replace it.

• Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If you hear unusual noise(s) coming from the unit, call a qualified servicer.
