FIGURE 1: Typical Installation with Required Clearances

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 Figure 1 "Typical Installation with Required Clearances" 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.).

Isolate the unit from rain gutters to avoid any possible wash out of the foundation.

ROOF INSTALLATION

When installing units on a roof, the structure must be capable of sup- porting the total weight of the unit, including a pad, lintel, rails, etc., which should be used to minimize the transmission of sound or vibra- tion into the conditioned space.

UNIT PLACEMENT

1.Provide a base in the pre-determined location.

2.Remove the shipping carton and inspect for possible damage.

3.Compressor tie-down bolts should remain tightened.

4.Position the unit on the base provided.

LIQUID LINE FILTER-DRIER

The air conditioning unit’s copper spun filter/dryer is located on the liq- uid line.

NOTICE

Replacements for the liquid line drier must be exactly the same as marked on the original factory drier. See Source 1 for O.E.M. replacement driers.

Failure to do so or using a substitute drier or a granular type may result in damage to the equipment.

TXV INSTALLATIONS

The following are the basic steps for installation. For detailed instruc- tions, refer to the Installation Instructions accompanying the TXV kit.

Install TXV kit as follows:

1.Relieve the holding charge from the indoor coil by depressing the Schrader valve stem located in the end of the suction line. Cut the spundown copper to allow installation of the suction line.

2.After holding charge is completely discharged, loosen and remove the schraeder cap seal.

3.Loosen and remove distributor cap seal.

4.Install the thermal expansion valve to the orifice distributor assembly with supplied fittings. Hand tighten and turn an additional 1/4 turn to seal. Do not overtighten fittings.

5.Install the liquid line to the top of the thermal expansion valve with fit- ting supplied with the liquid line. Hand modify the liquid line to align with casing opening. Hand tighten the liquid line and an additional 1/4 turn to seal.

6.Install the TXV equalizer line into the vapor line as follows:

a.Hand tighten the 1/4” SAE nut to the schraeder fitting and an additional 1/3 turn to seal.

7.At this time do not attach sensing bulb. This will be covered later after brazing of the lines.

PIPING CONNECTIONS

This system uses R-410A refrigerant which operates at higher pres- sures than R-22. No other refrigerant may be used in this system. Gauge sets, hoses, refrigerant containers, and recovery systems must be designed to handle R-410A. If you are unsure, consult the equipment manufacturer.

Never install a suction-line filter drier in the liquid line of an R-410A system. Failure to follow this warning can cause a fire, injury or death.
