1. Safety This is a safety alert symbol. When you see this symbol on labels or in manuals, be alert to the potential for personal injury. This is an attention alert symbol. When you see this symbol on labels or in manuals, be alert to the potential for personal injury. - Page 5 If using existing refrigerant lines make certain that all joints are brazed, not soldered. Scroll compressor dome temperatures may be hot. Do not touch the top of compressor; it may cause minor to severe burning. Decide the correct way of conveying the equipment. Try to transport this equipment with the original package.

Page 6: Inspection
Install the unit where the air inlet and air outlet are free from obstacles and strong wind. Install the unit in a dry and well ventilated place. Install the unit where the bearing surface is level and can bear weight of the unit, and is suitable for installing the unit horizontally without increasing noise or vibration. -
Page 7: Limitations
• Leak detectors should be designed to detect R410A. • Recovery equipment (including refrigerant recovery containers) must be specifically designed to handle R410A. • Do not use an R-22 TXV. • Good Refrigeration practices require the installation of a field supplied liquid line drier, as shown in Fig.1. -
Page 8: General
2. General The outdoor units are designed to be connected to a matching indoor coil with braze connect lines. Units are factory charged with refrigerant for a matching indoor coil plus 25 feet of field supplied lines. Matching indoor coils are available with a thermostatic expansion valve or an orifice for the most common usage. -

Maintain the clearances shown in Fig.2 and install the unit in a level position. -
Page 11: Unit Placement
3.4 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 nuts should remain tightened. 4. Position the unit on the base provided. This system uses R410A refrigerant which operates at higher pressure than R-22. No other refrigerant may be used in this system. -
Page 12: Factory Freferred Tie-Down Method
3. If unit must be elevated because of anticipated snow fall, secure unit and elevating stand such that unit and/or stand will not tip over or fall off. NOTE To tie down unit, see 3.6. Fig 4 Recomended elevated instalation 3.6 Factory-preferred tie-down method Step 1: Prior to installing clear pad of debris. - Page 13 Step 3: Using field supplied L-shaped bracket to locate holes on concrete and drill pilot holes which is at least 1/4” deeper than fastener being used. IMPORTANT Self drilling screws to base pan should not exceed 3/8” long to avoid damaging coil. Step 4: Using conventional practices to install brackets, tighten concrete fasteners and self-tapping screws (See Fig.5).

Page 14: Precautions During Line Installation
3.7 Precautions during line installation 1. Install the lines with as few bends as possible. Care must be taken not to damage the couplings or kink the tubing. Use clean hard drawn copper tubing where no appreciable amount of bending around obstruction is necessary, if soft copper must be used, care must be taken to avoid sharp bends which may cause a restriction. -
Page 15: Precautions During Brazing Of Lines
Note: All outdoor wiring must be weather proof Fig 8 Typical Installation 3.8 Precautions during brazing of lines All outdoor unit and evaporator coil connections are copper-to-copper and should be brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO NOT use soft solder. -
Page 16: Precautions During Brazing Service Valve
3.9 Precautions during brazing service valve Precautions should be taken to prevent heat damage to service valve by wrapping a wet rag around it as shown in Fig.9. Also, protect all painted surfaces, insulation, during brazing. After brazing cool joint with wet rag. The valve can be opened by removing the plunger cap and fully inserting a hex wrench into the stem and backing out counter-clockwise until valve stem just touches the chamfered retaining wall. -
