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 7: 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. -

Page 9: 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 10: Precautions During Brazing Of Lines
Fig.7 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. The outdoor units have reusable service valves on both the liquid and suction connections. - Page 11 Connect the refrigerant lines using the following procedure: 1. 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.
