Detailed cooling capacities* continued
NOTE: When the required data fall between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.
* Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per ARI standard 210/240-94. If additional tubing length
and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
† Total and sensible capacities are net capacities. Blower motor heat has been subtracted.
‡ Sensible capacities shown are based on 80°F (27 °C) entering air at the indoor coil. For sensible capacities at other than 80°F (27°C), deduct
835 Btuh (0.245 kW**) per 1,000 CFM (480 L/S) of indoor coil air for each degree below 80°F (27°C), or add 835 Btuh (0.245 kW**) per 1,000 CFM
(480 L/S) of indoor coil air per degree above 80°F (27°C).
** Unit kW** is total of indoor and outdoor unit kilowatts.
†† At TVA conditions (75 edb-63 ewb). All other indoor air temperatures are at 80 edb.

System Design
1. Intended for outdoor installation with free-air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wc.
2. Minimum outdoor operating air temperature is 55
°
F (12.8
°
C).
3. Low-ambient operation accessory is not available.
4. Maximum outdoor operating air temperature is 125
°
F (51.7
°
C).
5. For reliable operation, unit should be level in all horizontal planes.
6. Maximum elevation of indoor coil above or below base of outdoor unit is; indoor coil above–50 ft, indoor coil below–150 ft.
7. For interconnecting refrigerant tube lengths greater than 50 ft and/or 20 ft vertical differential, consult Application Guideline and Service Manual—
Air Conditioners and Heat Pumps Using Puron® Refrigerant.
8. If any refrigerant tubing is buried, provide a minimum 6-in. vertical rise to the valve connections at the unit. Refrigerant tubing lengths up to 36
in. may be buried without further consideration. Do not bury lines over 36 in.
9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
10. Use with hard shutoff, balance port TXV. If factory-supplied TXV (Thermostatic Expansion Valve) is provided, it must be installed. If it is not
provided from the factory and is required for the application, use only the approved TXV listed in the Accessory Section of this literature.
11. Do not apply capillary tube indoor coils to these units.
12. Factory-supplied filter drier must be installed.
