3.0 UNIT INSTALLATION 3.1 LOCATION Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. -
Page 8: Unit Mounting
The outdoor unit must be connected to the indoor coil using field supplied refrigerant grade copper tubing that is internally clean and dry. Units should be installed only with the tubing sizes for approved system combinations. The refrigerant charge shown in the nameplate is for standard size interconnecting liquid line lengths up to 15 feet. -

3.6 FACTORY-PREFERRED TIE-DOWN METHOD Step 1: Prior to installing clear pad of debris. IMPORTANT Then cement pad must meet local codes and must be the proper thickness to accommodate fasteners. Step 2: Center and level unit onto pad. Step 3: Using field supplied L-shaped bracket to locate holes on concrete and drill pilot holes which is at least 1/4”... -
Page 10: 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. -

Remove the cap and Schrader core from both the liquid and suction service valve service ports at the outdoor unit. Connect Iow pressure nitrogen to the liquid line service port. service valve wet rag Fig.8 Heat Protection 2.

10. Replace cap on service ports. Do not remove the flare caps from the service ports except when necessary for servicing the system. 11. Release the refrigerant charge into the system. Open both the liquid and suction valves by removing the plunger cap and with an hex wrench back out counter -clockwise until valve stem just touches the chamfered retaining wall. - Page 14 LINE SIZING TABLE 2: SUCTION LINE LENGTH/SIZE VS CAPACITY MULTIPLIER(R410A) 1 1/2 Ton 2 Ton 2 1/2 Ton 3 Ton 3 1/2 Ton 4 Ton 5 Ton Model Size Suction Line Connection Size 3/4" O.D. 3/4" O.D. 3/4" O.D. 3/4" O.D. 3/4"...
