UNIT MOUNTING
If elevating the condensing unit, either on a flat roof or on a slab, observe the
following guidelines.
• The base pan provided elevates the condenser coil 3/4” above the base pad.
• If elevating a unit on a flat roof, use 4” x 4” (or equivalent) stringers positioned
to distribute unit weight evenly and prevent noise and vibration.
FACTORY-PREFERRED TIE-DOWN METHOD
INSTRUCTIONS:
IMPORTANT: These instructions are intended as a guide to securing equipment for wind-
load ratings of “120 MPH sustained wind load” and “3-second, 150 MPH gust.” While this
procedure is not mandatory, the Manufacturer does recommend that equipment be prop-
erly secured in areas where high wind damage may occur.
STEP 1: Before installing, clear pad of any dirt or debris.
IMPORTANT: The pad must be constructed of industry-approved materials, and
must be thick enough to accommodate the concrete fastener.
STEP 2: Center basepan on pad, ensuring it is level.
STEP 3: Using metal straps as guides, mark spots on concrete where 4 holes will be
drilled (See Figure 2).
STEP 4: Drill four pilot holes in pad, ensuring that the hole is at least 1/4” deeper than the
concrete fastener being used.
STEP 5: Gauge the amount of washers needed by stacking washers and metal strap in
place, as shown in Figure 2, Detail A. Typical installation requires 6 to 7 wash-
ers.
STEP 6: Insert concrete fastener into hole in metal strap, insert washers over end of fas-
tener, and then insert into hole drilled into concrete.
STEP 7: Tighten concrete fastener.
NOTE: Do not over-tighten the concrete fastener. Doing so can weaken the
integrity of the concrete fastener and cause it to break.
STEP 8: Finish unit assembly per unit’s installation instructions.
REFRIGERANT CONNECTIONS
All units are factory charged with Refrigerant 22. All models are supplied with ser-
vice valves. Keep tube ends sealed until connection is to be made to prevent sys-
tem contamination.
