Before installing the indoor unit, check whether the refrigerant sensor is correctly installed The unit can be positioned for bottom return air in the according to Section 3.
  • Page 11 When the unit is installed in a hot and humid place, If the humidity inside the installation space might exceed 86℉ and RH 80%, it is recommended to insulate the cabinet exterior. Use glass wool or polyethylene foam as insulation so that the thickness is more than 2 inches and fits inside the installation space opening.

    5. AIRFLOW PERFORMANCE ( AIR HANDLERS ARE SUITABLE FOR MOBILE HOME APPLICATIONS) Airflow performance data is based on cooling performance with a coil and no filter in place. Select performance table for appropriate unit size. External static applied to unit allows operation within the minimum and maximum limits shown in table below for both cooling and electric heat operation.

  • Page 20: Ductwork

    Important: 1. When model 36 used with electrical heater kit model ZP-HR150-01, you need to ensure that the air volume is not less than 1260 CFM. 2. When model 42 used with electrical heater kit model ZP-HR150-01 and ZP-HR200-01, you need to ensure that the air volume is not less than 1452 CFM.

  • Page 21: About The Air Filter

    7 ABOUT THE AIR FILTER IMPORTANT: Do not double filter the return air duct system. Do not filter the supply air duct system. This will change the performance of the unit and reduce airflow. 7.1 Air Filter (Not Factory-Installed) WARNING Do not operate the system without filters.

  • Page 22: Drain Pipe Installation

    AIR FILTER REMOVAL 1. Remove bolts manually, remove air filter recover. See in Fig.7-1. 2. Hold the edge of the air filter and extract out. 3. Clean the air filter (Vacuum cleaner or pure water may be used to clean the air filter. If the dust accumulation is too heavy, use soft brush and mild detergent to clean it and dry out in cool place).
