Chapter 5: General Information
The ELA07, 6531_692 or 6571_662, and ELA12, 6533_892 or 6573_892 series package air
conditioners are intended for installation on the roof of elevator cabs or like-sized indoor use
contrivances. It is understood that the manufacturer has provided an installation area which
allows for cutouts and unit mounting without cutting vital frame members or electrical wiring and
that structural members do not create restrictions by passing through airways required by the air
conditioner. A recommended installation is shown in Figures 1a & 1b. Conditioned air is delivered
from the air conditioner to the interior of the enclosure through ducting that is supplied in Accessory
Kit (6531_625) for the ELA07, 6531_692 or 6571_662 and Accessory Kit (6533_625) for the
ELA12, 6533_892 or 6573_892 Models.
The system return air duct, return air lter and thermostat are also found in the Accessory Kit.

The LiftAire I Series of air conditioners are specically designed and constructed for use on new
elevator installations, modernizations and retrots of existing elevator cabs. They are provided with
all the materials needed to properly cool and/or heat an elevator cab. To ensure maximum efciency
and operation, the following should be adhered to:
1. Supply and return registers in the cab should not restrict airow into and out of the cab. Any
resistance of the airow will limit the effectiveness of the unit and create wind noise. The
return air and supply air registers should be as far away from each other to ensure proper air
recirculation in the cab and back to the air conditioner.
2. While the installation kit provides 12.5 ft (381 cm) of supply and return air exible duct,
in order to limit air ow resistance, all duct connections should be the most direct and the
shortest possible. Cut any extra exible duct not required, connect exible duct per previous
installation instructions (pages 6-10) and discard any extra material.
3. Ensure that the thermostat is installed in the return duct or the cab. If using the standard
thermostat, check that the temperature and operation settings are correct. If using the automatic
thermostat, make sure the unit is programmed for the type of operation you require. When the
thermostat is installed in the cab, it must be able to sense cab temperature to operate properly.
If placed within the xture area of the cab, there must be a perforated cover to allow cab air
access to the thermostat. Locating the thermostat anywhere else affects the proper operation of
the air conditioners and cooling of the elevator cab as designed.
4. If you are retrotting an existing cab for normal operating conditions, it may not be necessary
to use the fan supplied in the original cab. The LiftAire series of air conditioners has a fan that
will run continuously with proper settings of the thermostat. If you allow the cab fan to operate
during normal conditions you will bring hot, cold or humid hoistway air into the cab, thereby
defeating the purpose of the air conditioner and its effectiveness. If it is permitted, remove the
original fan to prevent allowing warm hoistway air into the cab during ascent and descent of
elevator. Or insure the fan only operates if the air conditioner cannot operate due to power loss,
etcetera.
5. All supply and return registers with duct work into the cab must be manufactured and installed
to prevent any air leaks and losses of the cold supply air from the air conditioner and return air
back to the air conditioner.
6. Never install the condensate evaporator under the return or supply air ducts. This can cause
water accumulation, damage to the ducts and damage to the cab.
7. It is the responsibiity of the installer to ensure that the installation meets any and all building,
electrical and other applicable codes.
8. Power cables must be sufciently sized for the FLA, LRA required and the length of cable
required.
9. Additional hoistway ventilation at the bottom and top is recommended.
