The 6571 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 Figure
1.
1.
The air conditioner draws in topside air to cool the
condensing coil. The condenser air is drawn in from
the end of the air conditioner (across the condensing
coil), and discharged out through the top of the
appliance (through the discharge opening). To
provide adequate condensing air flow, the installer
must adhere to the following guidelines:
a)
The topside air path to the condensing coil
should be as direct and non-restrictive as
possible.
b)
Any decorative grille or louver used as an
opening for condenser air flow should have
a minimum of 90 square inches of free area.
c)
Do not block or restrict the discharge air
opening.
d)
Insure that there are no structural members
or panels which would serve to cause
condenser discharge air recirculation into
the condenser return air.
2.
Mount the air conditioning unit. The four shipping
brackets may be used to secure the unit to the
mounting surface, or the installer may choose to use
bands or other types of bracketing.
3.
Attach the supply duct adaptor to the top of the unit
with the four existing screws in the unit top.
4.
Mount the thermostat to the thermostat bracket using
the screws provided with the thermostat.
5.
Cut a 10 1/8" square opening in the canopy. The
opening should be as remote as possible from the
intended position of the supply air distribution
scoop and away from any heat source such as
lighting.
5. GENERAL INFORMATION
6. UNIT INSTALLATION
6
Conditioned air is delivered from the air conditioner to the
interior of the enclosure through ducting that is supplied in
Accessory Kit #6531A625.
The system return air duct, return air filter and thermostat are
also found in the Accessory Kit.
The air conditioner is powered by a 240 volt, 50 Hz, 1 Phase,
10 Amp electrical service.
6.
Fasten the thermostat/bracket and the return air duct
adaptor over the square opening with screws or
rivets. Use a quality duct tape to seal around the
perimeter of the adaptor plate.
7.
Install the supply air distribution scoop inside the
conditioned space in an area as remote from the
return air as possible. Air from the scoop should
have a clear path into the conditioned area. Attach
the scoop with adhesive, straps, brackets or by
fastening through the part. If attaching with
fasteners, pre-drill any clearance holes in the scoop
to prevent cracking during installation. It is good
practice to mount the scoop as far as possible from
heat producing devices, such as lights, fixtures, etc.
8.
Cut a 6" dia. hole in the roof to allow passage of the
insulated 4" flex duct. The duct connects between
the 4" collar at the unit and the oval opening at the
air scoop. Secure the duct with 2 of the 4 cable ties
provided in the accessory kit.
9.
Secure the 7/8" I.D. condensate drain hose to the
unit
drain pan with the hose clamp provided in the kit.
10.
Mount the return air bonnet to the unit using
existing unit screws. Clearance holes on the return
air bonnet align with existing unit fasteners. Use a
good quality duct tape to seal the bottom and side
seams between the unit and return air bonnet.
11.
Install the return air filter inside the bonnet assembly
with the wire mesh of the filter facing the unit
evaporator coil.
12.
Attach the unit end of the return air flex duct to the
return air bonnet with one cable tie provided in the
kit.
