INSTALLATION
1. Provide a concrete pad or another form of stand. Use 6-12 each rubber/cork pads 4" x 4" x 1" thick each (rubber-in-
shear for example) at each corner and along side rails, or use 6-12 each spring isolators.
2. Service Clearance: To avoid condenser air obstructions/recirculation, and to give adequate service space, indicated
clearances must be observed. See drawing below.
3. All wiring must comply with NEC (National Electrical Code) and local electrical codes. The electric supply must
comply with the unit nameplate. See the typical wiring diagram for guidance.
4. All units are pre-charged with R-22 and oil, sealed and tested for leaks. Therefore do not attempt to open the system.
5. Install a flexible connection for duct work to minimize vibration transmission. Connect drain pipe (copper or PVC) to the nearest drain pit.
6. Care should be taken in locating the roof curb & roof opening. The packaged unit should be adequately mounted on roof.
7. Install & secure ductwork to curb prior to mounting unit on the roof curb.
RECOMMENDED SERVICE CLEARANCE
– Multiply 'A' by 1.5 if nearby low walls exist.
– Multiply 'A' by 2.0 if nearby high walls exist.
– FOR MULTIPLE UNIT INSTALLATION, distance between adjacent unit = 2A.
NOTE: There should not be any obstacles above condenser air discharge.
