FIGURE 2 RECOMMENDED ELEVATED INSTALLATION STEP 3: Using basepad as a guide, mark spots on concrete where 4 holes will be drilled (see Figure 3). STEP 4: Drill four pilot holes in pad, ensuring that the hole is at least 1/4" deeper than the concrete screw being used. STEP 5: Center basepan over pre-drilled holes and insert concrete screws. STEP 6: Tighten concrete screws. NOTE: Do not over-tighten the concrete screws. Doing so can weaken the integrity of the concrete screw and cause it to break. STEP 7: Finish unit assembly per unit's installation instructions. 4.0 REFRIGERANT CONNECTIONS All units are factory charged with Refrigerant 410A. All models are supplied with service valves.
