Fire Hazard
When heaters
are installed
maintain
clearances
from combustible
materials as specified on unit
rating plate. Do not use plastic lined or combustible
flexible ducting within 36 inches of the supply end of
the air handler.
Failure to do so can result in fire, property damage,
personal injury or death.
General
Information
Installation or repairs made by unqualified persons
can result in hazards to you and others. Installation
MUST conform with local building codes and with the
National Electrical Code NFPA70 current edition.
The information
contained
in this manual
is intended
for use by a qualified
service
technician
familiar
with
safety
procedures
and equipped
with
the proper
tools and test instruments.
Failure to carefully read and follow all instructions in
this manual can result in equipment malfunction,
property damage, personal injury and/or death.
The blower cabinet may be used for cooling or heat pump operation with
or without
electric heat. The cabinet can be installed in an upflow or
horizontal
position (Figure 2, 3). EBV models are shipped with the horizontal kit already installed.
Location
Select the best position which suits the installation
site conditions.
The
location should provide adequate structural support, space in the front of
the unit for service access, clearance for return air and supply duct connections,
space for refrigerant
piping connections
and condensate
drain line connections.
If heaters are being installed
make sure adequate clearance
is maintained
from supply ductwork,
(see Fig. 1).
NOTE: Internal
