Detailed cooling capacities* (S.I.) continued
* Detailed cooling capacities are based on indoor and outdoor unit at the same elevation and connected by 7.62m of tubing. If other than 7.62m of
tubing is used 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 27°C entering air at the indoor coil. For sensible capacities at other than 27°C, deduct 245 kw per 480
L/S of indoor coil air for each degree below 27°C, or add 245 kw per 480 L/S of indoor coil air per degree above 27°C.
When the required data falls between the published data, interpolation may be performed.
** Unit kw is total of indoor and outdoor unit kilowatts.

Detailed cooling capacities* (English) continued
* 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 (245 kw) per 1000 CFM (480 L/S) of indoor coil air for each degree below 80°F (27°C), or add 835 Btuh (245 kw) per 1000 CFM (480
L/S) of indoor coil air per degree above 80°F (27°C).
When the required data falls between the published data, interpolation may be performed.
** Unit kw is total of indoor and outdoor unit kilowatts.
