Step 2 — Rig and Place Unit RIGGING — The 09BY units are mounted on skids. Leavethe unit on the skid until it is in the final position. While onthe skid, the unit can be rolled, dragged or forklifted; do notapply force to the unit. Use a minimum of 3 rollers whenrolling, and raise from above to remo...

Step 3 — Install Accessory Low-Ambient Kit orInlet Filter Kit (If Required) — If the unit will be op- erated with inlet air to the condenser below 50 F, a low-ambient damper may be required. The low-ambient kit con-trols head pressure by discharge dampers on the condenserfan. The dampers are actuate...

LIQUID LIFT — Amount of liquid lift available before re-frigerant flashing occurs depends on amount of liquid sub-cooling in the system. All 09BY condensers have positive subcooling when ap- plied with optimum charge. With subcooling, it is possibleto overcome an appreciable pressure drop and/or sta...

CHECK VALVE — When the 09BY condenser is installedwith the condenser located above the compressor evapora-tor, it is recommended that a field-supplied check valve beinstalled on the hot gas discharge line. This prevents refrig-erant which condenses in the discharge line during the offcycle from drai...

3. A high-density fiberglass (2 lb minimum density) or semi- rigid foamed insulation such as Styrofoam™ will be re-quired inside the ducts to prevent air erosion. The insu-lation must be firmly secured in the discharge duct nearthe blower discharge to withstand the high air velocity. Step 7 — Insula...

Determine maximum deviation from average voltage:(AB) 243 – 239 = 4 v(BC) 239 – 236 = 3 v(AC) 239 – 238 = 1 vMaximum deviation is then 4 v. To determine the percentageof voltage imbalance: 4 % Voltage Imbalance = 100 x 239 = 1.7% This amount of phase imbalance is satisfactory since it is below the a...
