GENERAL DATA

R410A Refrigerant

R410A Refrigerant - 0% Ozone Depleting

R410A refrigerant has a higher operating pressure in comparison to R22 refrigerant and, therefore, all piping system materials installed must have a higher resisting pressure than the materials traditionally used in R22 systems.

R410A refrigerant is an azeotrope of R32 and R125, mixed at 50:50, so the ozone depletion potential (ODP) is 0.

• To prevent the refrigerant cylinder from exploding, do not place it in direct sunlight.

• Do not use any piping that has not been approved for use in high-pressure refrigerant systems.

• To prevent the piping from softening, do not heat it more than necessary during installation.

• Piping wall thickness must comply with the applicable local, state, and federal codes for the 551 psi design pressure of R410A.

• Because R410A is a combination of R32 and R125, the required additional refrigerant must be charged in its liquid state. If the refrig-

erant is charged in its gaseous state, its composition changes and the system will not work properly.

GENERAL INSTALLATION GUIDELINES

DANGER

Location Selection

Selecting the Best Location

To avoid the possibility of re, do not install the unit in an area where combustible gas may generate, ow, stagnate, or leak. Failure to do so can cause

serious bodily injury or death.

• Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it.

• Do not install the unit in a location where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death.

• Do not use the unit in environments where oil, steam, or sulfuric gas are present as this may cause serious bodily injury or death.

Select a location for installing the outdoor unit that will meet the following conditions:

• Where the unit will not be subjected to direct thermal radiation from other heat sources.

• Where operating sound from the unit will not disturb inhabitants of surrounding buildings.

• Where the unit will not be exposed to direct, strong winds.

• Where there is enough strength to bear the weight of the unit.

• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode.

• Include enough space for air flow and for service access.

General Installation Guidelines

To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or severe wind chill or cold:

1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena.

2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the system may malfunction.

3. Remove any snow that has accumulated by 4 inches or more on the top of the outdoor unit.

4. Place the outdoor unit on a raised platform at least 20 inches higher than the average annual snowfall for the area. In environments where there is a possibility of heavy snow, the frame height must be more than two (2) times the amount of average annual snowfall, and should not exceed the width of the outdoor unit. If the frame width is wider than the outdoor unit, snow may accumulate.

5. Install a snow protection hood.

6. To prevent snow and heavy rain from entering the outdoor unit, install the suction and discharge ducts facing away from direct winds.

7. Additionally, the following conditions should be taken into consideration when the unit operates in defrost mode:

• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot

of natural light. (Example: Install on a rooftop.)

• Sidewalks or parking lots near the outdoor unit may accumulate moisture after unit operates in defrost mode that can turn to ice.

The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed:

1. In a narrow, shady location.

2. Near a location that has a lot of ground moisture.

3. In a highly humid environment.

4. In an area in which condensate does not drain properly.

Ambient Air Conditions

• Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing

vents, or substances that may degrade performance or cause damage to the unit.

• When installing multiple outdoor units, avoid placing the units where discharge of one outdoor unit will blow into the inlet side of an adja-

cent unit.

Avoid exposing the unit to sources of extreme temperature or gases to prevent serious bodily injury.

Due to our policy of continuous product innovation, some specifications may change without notification.

GENERAL INSTALLATION GUIDELINES

Oceanside Applications

Use of a Windbreak to Shield from Sea Wind

Ocean winds may cause corrosion, particularly on the condenser and

evaporator ns, which, in turn could cause product malfunction or inefcient performance.

• The unit should be installed in a soundproofed mechanical room.

• Avoid installing the outdoor unit where it would be directly exposed

to ocean winds.

• Install the outdoor unit on the side of the building opposite from

direct ocean winds.

• Select a location with good drainage.

• Periodically clean dust or salt particles off of the heat exchanger

with fresh water.

• If the outdoor unit must be placed in a location where it would

be subjected to direct ocean winds, install a concrete windbreak strong enough to block any winds.

• Windbreak should be more than 150% of the outdoor unit’s height.

There must be 2ft and 3 1/2 inches clearance between the outdoor unit and the windbreaker for purposes of air flow.

Figure 1: Oceanside Placement Using Windbreak

Sea wind

Additional anti-corrosion treatment may need to be applied to the outdoor unit at oceanside locations.

Oceanside Applications

Use of a Building to Shield from Sea Wind

If a windbreak is not possible, a building or larger structure must be used to shield the outdoor unit from direct exposure to the sea wind. The unit should be placed on the side of the building directly opposite to the direction of the wind as shown in Figure 2.

Mounting Bolt Location

General Mounting

Securely attach the outdoor unit to a condenser pad, base rails, or another mounting platform that is securely anchored to the ground or building structure. Attach the outdoor unit with a bolt and nut on a concrete or rigid mount. See Figure 3. Follow applicable local codes for clearance, mounting, anchor and vibration attenuation requirements.

All referenced materials are to be eld-supplied. Images are not to scale.

Mounting Platform

The underlying structure or foundation must be designed to support the weight of the unit. Avoid placing the unit in a low lying area where water may accumulate. When installing the outdoor unit on the wall, or roof top, anchor the mounting base securely to account for wind, earthquake or vibration.

Tie-Downs and Wind Restraints

The strength of the Duct-free Split Single Zone Inverter system frame is adequate to be used with field-provided wind restraint tiedowns. The overall tie-down configuration must be approved by a local professional engineer.

Figure 3: Outdoor Unit Mounting Methods

General Installation Guidelines

Always refer to local code when designing a wind restraint system.

Snow and Ice Conditions

In climates that experience snow build-up, place the unit on a raised platform to ensure condenser airflow. The raised support platform must be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a minimum height that is equal to the average annual snowfall plus 20 inches. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet guards. Best practice prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where required by local codes.

When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on sidewalks or driveways.

Mounting of Indoor Unit

Detaching Front Panel from Indoor Unit

Before you can mount the indoor unit to the wall, you must remove the front cover. Removal will allow you to knock out any side holes for the drain hose, as well as allow you to mount the unit without damaging the front cover.

It is recommended that the front panel not be re-attached to the indoor

unit until the nal test has been run which will ensure that all electrical and

piping connections are working properly.

Procedure

1. Lay the indoor unit on a flat surface, and then pull the upper part

of the front panel away from the body.

2. Lift up the front panel so that the bottom part of the unit is visible.

3. Detach the front cover, by removing the two screws.

4. Remove the front cover away from the body, and be sure to disconnect the front panel connector as shown below.

Disconnect

Removing Side Bottom Covers and Piping Hole Knockout

Before mounting the indoor unit, you may need to remove either the right or left bottom side covers and the piping hole knockout, in order to pass the drain hose and piping through. This procedure should be done after removal of the front panel of the indoor unit.

Procedure

1. Using a phillips head screwdriver, remove the center bottom screw from the L-bracket tube holder (Figure 8).

2. Detach one of the side covers (either right or left depending on how you want to place the piping and drain hose).

3. Knockout the piping hole from the detached side cover.

After knocking out the piping hole from the side cover, be sure to smooth or cut any burrs around the hole. Burrs left on can lead to physical cuts and scrapes.

If you are planning to create a piping hole directly through the rear wall you might not need to knockout the piping hole from the side cover.

Preparing for Piping Connection

1. To prepare indoor unit for piping, remove the rubber plugs at the desired drain direction (left or right at bottom of the unit) (Figure 9).

• Be sure that the drain hose is routed to the closest pipe hole under

the unit.

2. Insert the drain hose into the opening/handle of the drain pan, and then attach the drain hose and connecting hose using recommended adhesive.

• Step 2 can be done once the indoor unit is mounted to the wall if

necessary.
