CAUTION This section is for information only and is not intended to provide all details required by the designer or installer of the refrigerant piping between the condenser or condensing unit and the air handling unit. AAON is not responsible for interconnecting refrigerant piping. Consult ASHRAE Handbook – Refrigeration and ASME Standards. Only clean ACR tubing should be used. Piping should conform to generally accepted practices and codes. exposing the coils to moisture.
Modulating Hot Gas Reheat Piping: 1. Run a hot gas reheat line from the condensing unit and connect it to the inlet of the stub-out on the reheat coil. The inlet connection is the top (or highest) stub-out of the reheat coil. Connect the hot gas line from the outdoor unit to the upper stub-out connection of the reheat coil. 2. Run a liquid line from the discharge of the reheat coil through a tee connection. Run a liquid line from the condenser, through a check valve to the other side of the tee.
Liquid refrigerant traveling upwards in a riser loses head pressure. If the evaporator is below the condenser, and the liquid line does not include risers, the gravitational force will increase the pressure of the liquid refrigerant. This will allow the refrigerant to withstand greater frictional losses without the occurrence of flashing prior to the TXV. A moisture-indicating sight glass may be field installed in the liquid line to indicate the occurrence of premature flashing or moisture in the line.
collects in the compressor from causing damage or wear. Make sure to provide support to maintain suction line positioning, and insulate completely between the evaporator and condensing unit. It is important to consider part load operation when sizing suction lines. At minimum capacity, refrigerant velocity may not be adequate to return oil up the vertical riser. Decreasing the diameter of the vertical riser will increase the velocity, but also the frictional loss.
from the compressor discharge to the low pressure side of the system in order to keep the evaporator from freezing and to maintain adequate refrigerant velocity for oil return at minimum load. Hot discharge gas is redirected to the evaporator inlet via an auxiliary side connector (ASC) to false load the evaporator when reduced suction pressure is sensed. Field piping between the condensing unit and the evaporator is required.
Hot Gas Reheat Guidelines Maintain velocities below a maximum of 3,500 fpm. A general minimum velocity guideline is 2,000 fpm. Startup (See back of the manual for startup form) WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life. Startup and service must be performed by a Factory Trained Service Technician. A copy of this IOM should be kept with the unit. Electric shock hazard.
If the band is field installed, a hand held pop-rivet tool is recommended for connecting the band ends together. Caution must be taken to assure that the band is tightly installed and no damage, denting or alteration to the wheel or blades occurs during the installation.
Filters Do not operate the unit without filters in place. Unit should be checked for correct filter placement during startup. Operation of the equipment without filters will result in a clogged evaporator coil. CAUTION Before completing startup and leaving the unit a complete operating cycle should be observed to verify that all components are functioning properly.
Subtract the saturated temperature from the measured suction line temperature to determine the evaporator superheat. Compare calculated superheat to the table below for the appropriate unit type and options. CAUTION DO NOT OVERCHARGE! Refrigerant overcharging leads to excess refrigerant in the condenser coils resulting in elevated compressor discharge pressure.
4. The sensing bulb is fully insulated. 5. If the sensing bulb is installed on a vertical portion of the suction line, the sensing bulb should be placed upstream of suction line trap.

Operation Maintenance Unit operations should be controlled with thermostat or unit controller, never at the main power supply, except for emergency or complete shutdown of the unit. (See back of the manual for maintenance log.) Electric Heating Operation When a call for heating (G and W1, W2, etc.) is made the supply fan motors and electric resistance heaters will energize.
E-Coated Coil Cleaning Documented routine cleaning of e-coated coils is required to maintain coating warranty coverage. WARNING Electric shock hazard. Shut off all electrical power to the unit to avoid shock hazard or injury from rotating parts. Surface loaded fibers or dirt should be removed prior to water rinse to prevent restriction of airflow. If unable to back wash the side of the coil opposite of the coils entering air side, then surface loaded fibers or dirt should be removed with a vacuum cleaner.
dust, soot, greasy residue, lint and other particulate: Enviro-Coil Concentrate, Part Number HEC01. Recommended Chloride Remover CHLOR*RID DTS™ should be used to remove soluble salts from the e-coated coil, but the directions must be followed closely. This product is not intended for use as a degreaser. Any grease or oil film should first be removed with the approved cleaning agent. Remove Barrier - Soluble salts adhere themselves to the substrate.
WARNING Electric shock hazard. Shut off all electrical power to the unit to avoid shock hazard or injury from rotating parts. It is strongly recommended that filter media be replaced monthly. Filters are located upstream of the evaporator coil. Open access panel and pull filters straight out to inspect all of the filters. Replace filters with the size indicated on each filter. Arrow on the replacement filters must point towards the blower.
