Installation Recommendations

In some cases noise in the living area has been traced to gas pulsations from improper installation of equipment.

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

2.In noise sensitive applications (such as bedrooms), when a lineset is mounted to ceiling joists or floor joists, the out- door unit must be located at least 10 ft (3.05 m) away. If this is not possible, create a line set configuration with enough bends to provide 10 ft (3.05 m) of total line set length outside the dwelling

3.Ensure that vapor and liquid tube diameters are appropriate for unit capacity.

4.Run refrigerant tubes as directly as possible by avoiding un- necessary turns and bends.

5.Leave some slack between structure and unit to absorb vi- bration.

6.When passing refrigerant tubes through the wall, seal open- ing with RTV or other pliable silicon-based caulk (see Fig. 1).

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

8.Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with tubing (see Fig. 1).

9.Ensure that tubing insulation is pliable and completely sur- rounds vapor tube.

10.When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing insulation. (See Fig. 1.)

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

!CAUTION

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage.

If proper lineset routing techniques are not followed, variable speed systems can be susceptible to lineset transmitted noise inside the dwelling and, in extreme cases, tubing breakage.

Fig. 1 - Connecting Tubing Installation

The outdoor unit contains the correct amount of refrigerant charge for operation with AHRI rated and factory-approved smallest indoor unit when connected by 15 ft (4.57 m) of field-supplied or factory accessory tubing.

Adjust refrigerant charge by adding or removing the charge to/from the unit depending on lineset length and indoor unit as calculated and displayed on the UI. The user interface (UI) calculates required charge adjustment and total system charge required. For proper unit operation, check refrigerant charge using charging information in the Check Charge section of this instruction.

IMPORTANT: Liquid-line size is 3/8-in. OD for all 280ANV applications including long line applications.

IMPORTANT: Always install the factory-supplied liquid-line filter drier. Obtain replacement filter driers from your distributor or branch.

IMPORTANT: Always install the factory-supplied muffler (part #LM10KK003) on the vapor line as described in the Factory Supplied Muffler Installation section of these instructions. Obtain replacement mufflers from you distributor or branch.

INSTALLATION

Specifications for this unit in residential new construction market require the outdoor unit, indoor unit (including metering device), refrigerant tubing sets, and filter drier, and muffler listed in pre-sale literature. There can be no deviation. Consult the Service Manual – Air Conditioners and Heat Pumps Using PuronRefrigerant to obtain required unit changes for specific applications and for R-22 retrofit.

Step 1 — Check Equipment and Job Site

Unpack Unit

Move to final location. Remove carton taking care not to damage unit.

This unit employs one louver spacer on each of the four sides to prevent louver movement during operation. The louver spacers are trapped between the coil surface and louver at the approximate center of each side (See Fig. 2). This louver spacer should be present and, if dislodged during shipment, must be reinstalled before unit is placed into operation.

Inspect Equipment

File claim with shipping company prior to installation if shipment is damaged or incomplete. Locate unit rating plate on unit corner panel. It contains information needed to properly install unit. Check rating plate to be sure unit matches job specifications.
