9. Selection Procedure Step 1. Determine cooling load requirements at design conditions. Required load conditions: Required cooling capacity (TC).............................. 21,000 Btu/h Sensible capacity (SHC) ........................................ 17,000 Btu/h Temperature air entering Outdoor Unit ................. 95°F Temperature air entering Indoor Unit ..................... 80°F DB/67°F WB DB — dry bulb temperature WB — wet bulb temperature Step 2. Select unit based on required cooling capacity. Based on Total Cooling Capacity, choose suitable model from the specification table. The model with net cooling capacity of 24,000 Btu/h is selected. The system is LT-E2460CL. Verify the unit performance at the given conditions in accordance with step 3. Step 3. Determine if system selected satisfies cooling requirements. Enter cooling capacities table on page 49 at high speed and 95°F outdoor entering air temperature with 80°F DB/67°F WB indoor entering air temperature. Total cooling capacity = 24,000 Btu/h, Sensible capacity=18,700 Btu/h To find capacity at intermediate conditions not in the table ; Interpolation should be used when design conditions are between two numbers that are in the capacity table. Extra-polation is not recommended. If the interconnecting piping length is more than 7.5m ; Find the capacity(%) at that particular interconnecting piping length from the coefficient of capacity change graph, on page 56. Multiply coefficient factor with Total Cooling Capacity & Sensible Capacity. Ex: At 30m interconnecting piping length, from coefficient of capacity change graph, coeffienct factor is 0.915.

Total Cooling Capacity = Capacity (%) x Total Cooling Capacity = 91.5x24000 = 21,960Btu/h 100 100 Sensible Capacity = Capacity (%) x Sensible Capacity = 91.5x18,700 = 17,111Btu/h 100 100

15. Installation 15.7 Indoor Unit Drain Piping

Upward routing not allowed

Pipe clamp

• Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. • The outside diameter of the drain connection on the indoor unit is 32mm.

Indoor unit

Maintenance drain port

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings • Be sure to install heat insulation on the drain piping.

1/50~1/100

Heat insulation material: Polyethylene foam with thickness more than 8 mm.

MAX 700mm

Drain test The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:

Feed water

Flexible drain hose (accessory) Main drain pipe

Drain Pump

Drain port

Glue the joint

Drain hose connection Use the clip (accessory)

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end. • Feed water to the flexible drain hose and check the piping for leakage. • Be sure to check the drain pump for normal operating and noise when electrical wiring is complete. • When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

Drain pan

CAUTION

Flexible drain hose

1/50~1/100

The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water.

CAUTION

MAX 700mm

Flexible drain hose

After the confirmation of the above conditions, prepare the wiring as follows: Flexible drain hose 1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Never fail to equip a leakage breaker where it is wet or moist. 9) The following troubles would be caused by voltage drop-down. • Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. • Proper starting power is not given to the compressor.
