Unit Placement
In addition to clearances, the following items should be
considered:
WARNING
Use the provided and specified components when
installing equipment. Failure to do so may result in
unit falling, water leaking or electrical shocks, caus ing
personal injury or equipment or property dam age.
Check suitability of structure to which the unit support
mechanism will be fixed to. If structure is not capable
of carrying the weight of the unit, unit may fall causing
personal injury or equipment damage.
Consider the possibility of earthquakes in your area
when installing the equipment. If the unit is not
correctly secured, it may fall, causing personal injury
or equipment damage.
Safely dispose of packing materials, which include
nails, wood and other sharp objects, as well as plastic
wrapping. Children playing with plastic wrap or bags
risk the danger of suffocation.
Remove tape
from Receiver
(rear of electrical
control box) prior to
commissioning
CAUTION
Do not place items which may be damaged by water
under or around the unit.
The unit should be installed at least 8 feet above the
floor (if possible) to ensure maximum performance and
comfort.
Unit Installation
Unit Installation Guidelines
•
Install a field-provided isolation grommet as shown in
Figure 4 to prevent transmission of vibration from unit
to structural ceiling.
•
Provide separate support for the weight of the duct
system. Duct system must not be supported by the
indoor unit.
•
It is recommended that you use flexible joints (canvas)
at the point where the duct connects to the unit on
both ends. Material must meet all local and national
code requirements.
AVOID
Do not install the unit in the following locations:
•
Areas exposed to petrochemicals or petrochemical
products
•
Areas exposed to salt or other corrosive materials or
caustic gasses
•
Areas exposed to extreme voltage variations (such as
factories
•
Tightly enclosed areas that may impede service of the
unit
•
Areas exposed to fossil fuels (such as oil or gas in
kitchens)
•
Areas exposed to strong electromagnetic forces
•
Areas exposed to acids or alkaline detergents (laundry
rooms)
DO:
•
Locate the unit so that it is not exposed to direct
sunlight
•
Ensure the structural ceiling can support the weight
of the unit.
•
Select a location where condensate line will have the
shortest run to a suitable drain per local codes.
•
Allow sufficient space around unit for proper operation
and maintenance
•
Install unit a minimum of 3 feet (1 meter) away from
any antenna, power cord (line) radio, telephone,
security system, or intercom. Electrical interference
and radio frequencies from any of these sources may
affect operation
•
Be sure to instruct customers how to properly
operate the unit (especially maintenance of air filter,
and operation procedure) by having them carry out
operations themselves while looking at the manual
provided with the equipment.
•
When unit is being installed in a location where even
the slightest noise would be a problem (meeting room
or other very quiet space), design duct system to
avoid transmission of vibration to the structure to the
extent possible.
•
For Ducted return systems, a minimum surface area
of 200 sq. in. per ton is recommended.
Example: 3 Ton IDU.
3 tons x 200 sq. in. per ton = 600 sq. in.
