INSTALLATION Condensing Unit Location

The condensing unit should be located outdoors as close as possible to the evaporator. Consider the following factors:

Clearances

The air inlet should be located at least 12" from a wall or other

bstruction for unrestricted air flow.

o The air outlet should be located so as to direct discharged air

away from the building. Three feet of clearance around the unit and a minimum of six feet clearance above the unit is required to avoid recirculation of condenser discharge air on vertical discharge models. Avoid locating unit under low overhanging roofs.

Support

Mount the unit on a sturdy base approximately four to six inches above the ground. In areas known for snow accumulation, the unit should be elevated at least 18" above the ground. A concrete slab is recommended. Concrete slab should not contact the building foundation to prevent possible sound or vibration transmission.

Rooftop installation is acceptable in areas of low snow accumulations, provided the roof will support the unit and provisions are made for water drainage and the noise or vibration through the structure.

Exposure

If practical, unit should be located on the south side of the structure away from northerly winds to minimize the effects of blowing snowdrifts and freezing rain. A wind screen or wind block can also be used.

Placement of the unit should be in a well-drained area, or the unit must be supported high enough so run-off will not enter the unit.

Avoid installations under roof overhangs without guttering. Water draining from the roof onto the unit could produce excessive noise and may cause ice to build up on the coil or fan during cold weather.

Locate unit away from windows, patios, decks, etc. where unit operation sound may disturb customer.

Do not locate where heat, lint or exhaust fumes will be discharged on the unit (as from dryer or furnace vent).

112

Proximity to Evaporator

Locating the condenser as close as possible to the evaporator will increase the system capacities by reducing the line set refrigerant pressure drop, and will make the system less

usceptible to liquid migrations due to less refrigerant charge.

Electrical Connections (cont.)

Connect control wiring

1. Route 24 volt control wires through control wiring grommet and connect leads to control wiring.

. Use No. 18 AWG color coded, insulated wire. If thermostat is

located more than 100 ft. from unit, as measured along the control voltage wires, use No. 16 AWG wire to avoid excessive voltage drop.

3. All wiring must be NEC Class 1 and must be separated from incoming power leads. Use furnace transformer, fan coil transformer, or accessory transformer for control power.

ote: Use of available 24 volt accessories may exceed the

N minimum power requirement. Determine total transformer load and increase the transformer capacity or split the load with an accessory transformer as required.

Final Wiring Check

Check factory wiring and field wire connections to ensure terminations are secured properly ensure wires are not in contact with tubing, sheet metal, etc.

. Check wire routing to

SERVICE VALVE CONNECTIONS

Braze Joints

1. Remove the valve core from the schrader port. Wrap a

quenching cloth around the service valve. Clean and flux the joint and braze with brazing rod containing at least 10% silver (such as silphos type brazing rod). DO NOT USE SOFT SOLDER. Replace the schrader valve core after brazing has cooled.

2. Leak-check all braze joints at approximately 80 psi pressure,

purge and evacuate the lines.

Evacuation

The outdoor unit is factory charged. Evacuation is necessary

n the uncharged portions of the total system. Purge the

o system with dry nitrogen. Then connect a vacuum pump and a vacuum gage capable of accurately measuring below 1,000 microns vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and

iquid water.

WARNING

IF THE INSTALLER IS MAKING UP HIS OWN LINE SETS, HE MUST MAKE SURE THE TUBING IS CLEAN OF ANY IMPURITIES OR MOISTURE.

Opening the Service Valve (Step Valve)

NOTE: This is not a back-seating valve.

1. Remove the valve cap using an adjustable wrench.

2. Open the valve by inserting a hex wrench (3/16" for the liquid line, 5/16" for the vapor line) into the stem and back out counter-clockwise until the valve stem just touches the retaining ring. Do not over tighten.

INDOOR COIL

LIQUID LINE

SUCTION LINE

The following should be followed when installing refrigerant piping. Comply with all local, state, and federal codes and/or

egulations pertaining to this type of equipment and its

r installation.

1. Run the tubing by the most direct route and support every few feet. Do not run the lines underground unless

hey are in a chase. Leave enough material between

t structure and unit to absorb vibration.

2. Insulate the vapor line to prevent sweating and line loss. In underground chases, the vapor line should be insulated to provide vibration isolation between the vapor and liquid line. A minimum of 3/8” insulation is recommended in conditioned space and 1/2” to 3/4” in unconditioned space. Ensure that tubing insulation is pliable and completely surrounds vapor tube.

3. In general, the piping should be sloped toward the outdoor unit to prevent oil trapping. Where vertical risers occur, a suction line trap should be located at the base of the riser to assure proper oil return.

WARNING

REFRIGERANT LINE LENGTH MUST NOT EXCEED 75’ ON HORIZONTAL RUNS AND 40’ ON VERTICAL RISERS.

118

Precautions

efer to the chart below for the minimum recommended tube

R outside diameter sizes on liquid and suction lines. Ensure that vapor and liquid tube diameters are appropriate for unit capacity. Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends.

• Undersized line sets will increase the refrigerant pressure drop between the indoor evaporator and outdoor unit, resulting in a decrease in system capacity. Oversizing the line

ets may result in excessive refrigerant charge, thereby

s making the system more susceptible to liquid migration.

• When passing refrigerant tubes through the wall, seal

pening with RTV or other pliable silicon based caulk

• Avoid direct tubing contact with water pipes, duct work, floor joists, wall studs, floors, and walls

• Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with tubing

• When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing insulation

• Isolate hanger straps from insulation by using metal sleeves bent to conform to shape of insulation

• Condensing units are available with pre-charged, sweat-type copper connecting fittings

Units are factory charged for 15’ of line set tubing.

• Adjust charge 0.66 oz per foot of variation from chart for 3/8” and 3/4” line set.

• Adjust charge 0.67 oz per foot of variation from chart for 3/8" and 7/8" line set.

• Adjust charge 0.72 oz per foot of variation from chart for 1/2" and 1 1/8" line set.

Can only be 20’ vertical separation without additional accessories.

ARNING

IF THE INSTALLER IS MAKING UP HIS OWN LINE SETS, HE MUST MAKE SURE THE TUBING IS CLEAN OF ANY IMPURITIES OR MOISTURE. USE ONLY CLEAN AIR CONDITIONING AND REFRIGERATION GRADE SEAMLESS COPPER TUBING. PLUMBING GRADE COPPER IS INADEQUATE. TO ENSURE A CLEAN SYSTEM FREE OF ANY CONTAMINANTS, PURGING WITH DRY NITROGEN AND A DEEP VACUUM IS NECESSARY ON ALL SWEAT-TYPE MODELS AND ON THE UNCHARGED PORTIONS OF ALL MODELS NOT INCORPORATING PRECHARGED LINES. IT IS DESIRABLE TO PULL A VACUUM TO 1,000 MICRONS (29.96” HG) TO ENSURE TROUBLE FREE OPERATION.

SUB-COOLING CHARGING

For proper sub-cooling readings, a standard high side gauge is required for pressure readings.

se the charts below to determine the required sub-cooling value.

INSTRUCTIONS

1. Measure the outdoor air temperature. (T1)

2. Measure the liquid line pressure and determine the liquid refrigerant temperature by the scale on the high side pressure gauge. (T2) In cooling mode take reading at the indoor coil before TXV. In heating mode take reading at the

iquid line service valve on outdoor unit.

3. Measure the liquid line temperature on the liquid line. (T3) In cooling mode take reading at the indoor coil before TXV. In heating mode take reading at the liquid line service valve on outdoor unit.

4. Subtract T3 from T2. (T2 – T3) This is the subcooling value. Compare this value and the outdoor temperature (T1), to the charts below. If the value is below the line, add refrigerant. If the value is above the line, remove refrigerant charge. When removing refrigerant, always use standard reclaim procedures.

Adjusting TXV

For the majority of installations no adjustment to the TXV setting is required. However, if the measured superheat at the indoor coil is less than 4° or greater than 8° an adjustment is required. The adjustment stem is at the base of the valve under the flare nut. To increase superheat, tighten the stem clockwise and to decrease superheat, back-out the stem counterclockwise. Use a 1/4” refrigeration service wrench for this function.

FINAL CHECKS FOR INSTALLER

1. Ensure that all wiring is routed away from tubing and sheet metal edges to prevent rub-through or wire pinching.

. Ensure that all wiring and tubing is secure in unit before

adding panels and covers.

3. Tighten service valve stem caps to 1/12 turn past finger tight.

4. Leave this manual with owner. Explain system operation and periodic maintenance requirements outlined in manual.

COOLING OPERATION

urn the thermostat heat/cool switch to the cool position.

T Set the desired temperature on the thermostat dial. Do not operate the cooling unit for extended periods at indoor temperatures over 85°F. The unit indoor design temperature range is between 70°F and 80°F in the cooling mode.

It is not recommended to vary the temperature settings more than 5°F. Varying the temperature more than 5 degrees or turning the thermostat off for periods less than 12 hours can actually cost you more in energy consumption than keeping the temperature constant. Consider indoor plants and pets when varying the temperature from the normal comfort level.

HEATING OPERATION

Turn the thermostat heat/cool switch to the heat position. Set the desired temperature on the thermostat dial. Do not operate the heating unit at indoor temperatures over 80°F. The unit indoor design temperature range is between 65°F and 80°F in the heating mode.

Never operate the unit in the cooling mode at outdoor temperatures below 60°F without a low ambient control. Never operate the unit in the heating mode at outdoor temperatures above 70°F.

Auxiliary heat

Most heat pump installations include electric resistance heat for auxiliary heat (when the outdoor temperature is too low for the heat pump to provide enough heat) and for emergency heat (the outdoor unit is not working). On a properly-sized installation the heat pump will supply all the heat needed during cool weather. As the temperature drops, the heat output from the heat pump will be reduced. The auxiliary heat installed in the system will come on as needed to make up for this reduction of heat output.

The need for auxiliary heat is detected by the thermostat. If the thermostat senses a temperature fall of more than 2°F below the set point, the auxiliary heat will turn on. For this reason, setting the thermostat to the desired temperature and not changing the temperature during the day can be more economical than varying the thermostat setting.

If it is intended to set the temperature back at night, consider that, when the temperature is turned back up to the normal setting, the system will be operating during the coldest time of the day (early morning hours) and may require auxiliary heat if the increase in temperature is above 2

Emergency heat

This switch will turn the outdoor unit off and use the electric auxiliary heat only to provide heat. If outdoor unit should malfunction, turn the emergency heat switch to the ON position and contact your service person.

DEFROST OPERATION

The heat pump has a control system designed to defrost the outdoor coil by warming it up to keep it clear of ice and operating efficiently. When the temperature drops below 40°F, the control system will sense that conditions are right for the formation of ice. After a time period of 60 to 90 minutes, the

eat pump will go into the defrost mode. At this time, the

utdoor coil may be heavily iced or no ice may be visible,

epending on the outdoor humidity. When the unit starts the

d defrost mode, the outdoor fan will turn off and a hissing noise may be heard that disappears as defrost continues. As the outdoor coil warms, you may notice steam coming off the coil. When the coil reaches a predetermined temperature (usually within 7 minutes), the defrost cycle will end. You may hear a hiss as the unit switches back to the normal heating mode.

CAUTION

Wait at least 3 minutes after turning the heat pump off before trying to restart. If an attempt is made to start the compressor before the refrigerant pressures are equalized, the unit may fail to restart. An additional waiting period will then be required before restarting.
