MODEL INFORMATION Model Drawing How to Read Model Numbers LB16 1 - 10 2 6 2 3 4 - G015 5 1. Identifies the type/family of air conditioner and the approximate height (i.e. LB16 = LOBOY family about 16” high). 2. This is the air conditioner’s listed capacity in Btu/hr at rated conditions. (i.e. 10 = 10,000 Btuh at 125/125F) 3. 1 = 115 Volt, 2 = 230 Volt, 4 = 460 Volt. 4. 6 = 50/60 Hz or 60 Hz only. 5. Unique set of numbers for each air conditioner which identifies the accessories on a model.
INSTALLATION INSTRUCTIONS Figure 1 – Cutout Drawing 5 Ton Step 1: Inspect air conditioner. Verify functionality before mounting the air conditioner, see Handling & Testing the Air Conditioner on page 1. Step 2: Use the cut out drawing in Figure 1 for proper openings for the air conditioner. Using the mounting gasket kit provided with the unit, install gaskets to the air conditioner. Step 3: Mount air conditioner on enclosure taking care not to damage the mounting gasket.
TECHNICAL INFORMATION Sequence of Operation The air conditioner comes standard with one internally mounted thermostat. When the unit is plugged in, the evaporator fan will be running. Cooling When the enclosure temperature is above the cooling thermostat setpoint, power is applied through the time delay relay. After the delay time the contactor is energized and the compressor starts. The condenser fan will start once the compressor starts. Component specific information is listed below.

Troubleshooting 1. Check manufacturer’s nameplate located on the unit for correct power supply. 2. Turn the power to the unit on. The evaporator (Enclosure or “COLD” air) blower should there airflow? come on. Is YES, proceed to step # 3. NO, possible: Repair or Replace defective parts. Open motor winding Stuck blower motor Obstructed wheels/blades 3. Check thermostat setting? Adjust thermostat to the lowest setting. This should turn the condenser blower and the compressor on.
Symptoms and Possible Causes: SYMPTOM POSSIBLE CAUSE Unit won’t cool * Clogged fins on coil(s) * Dirty filters * Blowers/fans not running * Compressor not running * Compressor runs, but has bad valves * Loss of refrigerant Compressor tries to start but won’t run * Low line voltage at start.
