  • Page 15: Application Data

    FORM TPM1-EG1 (516) Application Data GENERAL The TempMaster OmniElite air conditioning units are designed for outdoor installation. When selecting a site for installation, be guided by the following conditions: • Unit must be installed on a level surface. • For the outdoor location of the unit, select a place having a minimum sun exposure and an adequate supply of fresh air for the condenser.
  • Page 16 LD08044 NOTE: 1. Under certain conditions these clearances may be encroached upon. However, doing so may impact system performance. 2. This is a visual reference for all TempMaster OmniElite units. FIGURE 2 - UNIT CLEARANCES RIGGING Proper rigging and handling of the equipment is mandatory during unloading and setting it into position to retain warranty status. Rigging and lifting should only be done by a profes- sional rigger in accordance with a written rigging and lifting plan.
  • Page 17 OA = Outside Air NOTE: This diagram is provided as a visual reference of the TempMaster OmniElite discharge & return air openings & locations for all sizes. Please refer to the dimensional data for exact size & location of panels and openings.
  • Page 18 If the applica- tion calls for horizontal supply and return air, TempMaster can ship it from the factory as a horizontal unit. This option alleviates the need for field modification of equipment, sav- ing time and money.
  • Page 19 In this application, a powered exhaust fan may be suitable, however careful consideration of the fan type is necessary. TempMaster offers a centrifugal powered exhaust fan to perform this function. Some manufacturers use a propeller exhaust fan, which cannot handle the static pressure requirements.
