General Information RL Series packaged rooftop and outdoor air handling units have been designed for outdoor installation only. 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. CAUTION These units must not be used for heating or cooling at any time during any phase of construction.
CAUTION The Clean Air Act of 1990 bans the intentional venting of refrigerant as of July 1, 1992. Approved methods of recovery, recycling, or reclaiming must be followed. WARNING Coils and sheet metal surfaces present sharp edges and care must be taken when working with this equipment. WARNING Failure to observe the following instructions will result in premature failure of your system and possible voiding of the warranty.
accumulation out of the compressor before it is started. Always control the unit from the thermostat, or control panel, never at the main power supply, except for emergency or complete shutdown of the unit. During the cooling season, if the airflow is reduced due to dirty air filters or any other reason, the cooling coils can get too cold which will cause excessive liquid to return to the compressor.
If codes require a condensate drain line, the line should be the same pipe size or larger than the drain connection, include a p-trap, and pitch downward toward drain. An air break should be used with long runs of condensate lines. Table 1 - Unit Clearances Location Front Back Left End Right End Top Clearance 100” 100” 100” 100” Unobstructed CAUTION Unit should not be operated without a p-trap. Failure to install a p-trap may result in overflow of condensate water.
Duct Connection CAUTION All roofing work should be performed by competent roofing contractors to avoid any possible leakage. CAUTION Where the supply or warm air duct passes through a combustible roof, a clearance of 1 inch must be maintained between the outside edges of the duct and combustible material in accordance with National Fire Protection Association Standard No. 90A.
Before lifting unit, be sure that all shipping material has been removed from the unit. Secure hooks and cables at all marked lifting points provided on the unit. Hoist unit to a point directly above the curb and duct openings. Be sure that the gasket material has been applied to the curb. Carefully lower and align unit with utility and duct openings. Lower the unit until the unit skirt fits around the curb. Make sure the unit is properly seated on the curb and is level.
Reassembling Split Units Some RL Series units are built and shipped in two separate sections. 6. Apply butyl caulking to all seams and perimeter of splice and to the perimeter of the roof splice cap against the roof of the unit. Shipping covers should be removed from the ends where the sections will connect. Lifting and setting the largest section first is recommended, checking for the correct location and position.
Electrical Connection of Split Units Before attempting to make wire connections between sections it is important to refer to the unit specific wiring diagram located in the unit controls compartment to obtain additional details related to the wiring of the specific unit. Outdoor air intake adjustments should be made according to building ventilation or local code requirements. Air hoods vary according to unit size and options. Figure below is shown as a practical guideline for all outside air rain hoods.
WARNING Figure 10 - Factory Supplied End Flashings CAUTION In order to prevent water leakage into the roof curb, the factory provided sheet metal flashings MUST BE attached to the unit base to cover the shipping slots at both ends of the unit. Vestibule Exhaust Fan Prior to unit operation of units with service vestibules the exhaust fan shipping support must be removed from the exterior of the unit The exhaust fan also includes a factory provide exterior rain hood which must be installed.
CAUTION Figure 12 - Terminal Block Startup technician must check for proper motor rotation and check blower motor amperage listed on the motor nameplate is not exceeded. Motor overload protection may be a function of the variable frequency drive and must not be bypassed. Rotation must be checked on all MOTORS AND COMPRESSORS of three phase units.
(Canada) National Fuel & Propane Installation Code CSA B149.1 or B149.2. Gas Heating WARNING Table 3 - Gas Piping Connections FOR YOUR SAFETY Read the entire gas heating installation section of this manual before beginning installation of the gas heating section. If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.
A factory installed pressure tap on the outlet end of the gas valve can be used to verify a manifold pressure of 3.5” w.c. for natural gas, or 10.5” w.c. for propane. For two stage gas valves, the low stage setting should be set at 1.1” w.c. for natural, 5.0” w.c. for propane.
DANGER LEAK CHECK GAS PIPE The gas pipe in the unit should be checked for leaks before startup. Leak checking is the responsibility of the installing contractor. All connections should be checked for leaks annually after installation. Failure to leak check could result in fire, explosion, or other hazardous situations. Installation of the gas heaters should be adjusted to obtain an air temperature rise within the range specified on the rating plate.
CAUTION Unit should not be operated without a p-trap. Failure to install a p-trap may result in overflow of condensate water into the unit. Figure 14 - Gas Heater Rain Hood Screws WARNING All exterior heater rain hoods must be in place before the gas fired heater is initially started. Improper and dangerous operating conditions will otherwise result.
Draw-Through Coils Figure 15 - Draw-Through Drain Trap The X dimension on the draw-through trap should be at least equal to the absolute value of the negative static pressure in the drain pan plus one inch. To calculate the static pressure at the drain pan add the pressure drops of all components upstream of the drain pan, including the cooling coil, and add the return duct static pressure. Include the dirt allowance pressure drop for the filters to account for the worst-case scenario.
minimum pressure drop, so do not include dirt allowance pressure drops for filters. The bottom of the leaving pipe should be at least one half inch lower than the bottom of the drain pan connection. This ensures proper drainage when the unit is not running. Note: It may be necessary to fill the trap manually, or the trap can be filled automatically by operating the unit until enough condensate collects to fill the trap. The trap will then be filled when the unit is turned off.

the neoprene gasket. The front isolators should be adjusted until this gap measures approximately ¼” for units with three or four blowers, or two blowers in a vertical configuration (shown in Figure 27). For units with a single blower, or two blowers positioned side by side, the gap should be approximately 1/8”. 5. Check all isolators to ensure that the spring, spring cap and spring base plate are aligned. The position of the spring cap should be adjusted such that the spring is straight up and down.
Figure 31 - Top Clip and Side Spring Fastener Securing Filters in Place Figure 29 - Closed Back Draft Damper The back draft damper will remain open with no back pressure on the damper (see Figure 30). The damper will close completely when back pressure is applied. CAUTION Before completing startup and leaving the unit a complete operating cycle should be observed to verify that all components are functioning properly.
get the proper charge. After charging, unit should be operated in reheat (dehumidification) mode to check for correct operation. After adding or removing charge the system must be allowed to stabilize, typically 10-15 minutes, before making any other adjustments. The type of unit and options determine the ranges for liquid sub-cooling and evaporator superheat. Refer to the table below when determining the proper sub-cooling.
Adjusting Sub-cooling and Superheat Temperatures The system is overcharged if the sub-cooling temperature is too high and the evaporator is fully loaded (low loads on the evaporator result in increased sub-cooling) and the evaporator superheat is within the temperature range as shown in the table above (high superheat results in increased sub-cooling).

Access Doors Lockable access doors are provided to the services vestibule and to sections of the unit which may require maintenance or servicing. After startup is completed, if necessary, locks should be used with the doors to prevent unauthorized access.
Operation 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. Indirect Gas Heater Operation When heat (G and W1, W2, etc.) is called for the combustion motor starts and the ignition control is energized. The control sends 24 VAC to the gas valve and high voltage to the igniter. If a burner flame has been detected within 10 seconds, the spark is extinguished and the flame continues.
Maintenance (See back of the manual for maintenance log) At least once each year, a qualified service technician should check out the unit. Fans, evaporator coils and filters should be inspected monthly. Gas Heating WARNING Once a year, before the unit is in operation for the heating season, a qualified service technician should inspect all flue product carrying areas of the furnace and main burners for continued safe operation.
Figure 34 - Typical Factory Mutual (FM) Gas Piping Schematic for a Direct Fired Heater The burner comes with a pilot to ignite the flame and the pilot includes an adjustable orifice. An ignition transformer and spark igniter provide the spark to ignite the pilot and the pilot lights the main burner. The pilot and main burner flames are verified with a flame rod or UV flame supervisor. Capacity is controlled by a modulating gas valve. Ignition Sequence of Operations: 1.
125% of the maximum manifold gas pressure as shown on the unit nameplate. 7. There is an adjustable manual reset low gas pressure switch on Main Gas Valve 1. This switch should be set to trip at the minimum manifold gas pressure as shown on the unit nameplate. 8. There is an automatic reset valve proving switch located between the main shut off valves. This switch should be set at 50% of the incoming gas pressure. Initial Start-up Procedure: 1. Bleed air from main gas line. 2.
4. Ensure that all vents to the atmosphere are clean and free from obstruction. 5. Inspect and clean all drip legs in the gas lines. 6. Inspect all electrical components, connections and terminals. Clean and tighten as necessary. 7. Clean ignition electrodes if necessary. 8. Put system back into operation and observe the complete operation of the burners through the full firing range. There is an observation viewport window in the gas piping compartment. 9.
Condensate Drain Pans Drain pans will have moisture present and require periodic cleaning to prevent microbial growth. Cleaning of the drain pans will also prevent any possible plugging of the drain lines and overflow of the pan itself. Cleaning of the drain pans and inside of the unit should be done only by qualified personnel. Supply Fans WARNING Electric shock hazard. Shut off all electrical power to the unit to avoid shock hazard or injury from rotating parts.
WARNING Batch-loading chemicals into the unit is NOT PERMITTED. The control system must regulate the chemical feed. Severe Service The following recommended maintenance procedures are basic requirements for normal operating environments. For severe operating conditions, the frequency of inspection and service should be increased.

in it. As water is evaporated from the condenser, these minerals remain. As the mineral content of the water increases, the conductivity of the water increases. The water treatment controller monitors this conductivity. As the water conductivity rises above set point, the controller will open a motorized ball valve on the discharge side of the condenser pump and dumps water into the condenser drain until conductivity is lowered.
If a fault occurs in the evaporative condenser fan motor VFD, normally closed fault terminals on the VFD will interrupt the safety circuit, thereby shutting down the system. If the VFD does fault and cannot be reset, there is a VFD bypass switch mounted near the VFD. This switch has four positions— line, off, drive, and test. The “line” position will bypass the VFD, sending power to the motor. In this position, the condenser fans will run at full speed.

Mist Eliminators The mist eliminators must be correctly positioned when they are replaced during cleaning or service. Water Quality Air Inlet Inspect the air inlet louvers and mist eliminators into the condenser section on a monthly basis to remove any paper, leaves or other debris that may block the airflow.
will be removed when the heat load is less that design. The AAON evaporative-cooled condenser is equipped with a desuperheater. The desuperheater coil is located above the eliminators. Approximately 22% of the total heat of rejection is accomplished with the desuperheater. Water usage of the AAON evaporative-cooled condenser is approximately 22% less than evaporative condensers not equipped with a desuperheater.
recommendations on chemical cleaning procedures. Air-Cooled Condenser The air-cooled condenser section rejects heat by passing outdoor air over the fin tube coils for cooling of the hot refrigerant gas from the compressors. The heated air will discharge from the top of the section through the axial flow fans. 64 The condenser coils should be inspected yearly to ensure unrestricted airflow.
