INSTALLATION/OPERATION SAFETY RULES:
1. Read these rules and instructions carefully.
Failure to follow these rules and the installation
instructions could cause a malfunction of the unit,
and a possible safety hazard. Keep these
instructions nearby the unit for future reference.
2. While this unit has been designed and
manufactured to comply with National codes, it is
the installer’s responsibility to install this unit to
comply with Nationa
l codes and/or prevailing
local codes and regulations. HCI assumes no
responsibility for units installed in violation of
any code or regulation.
3. Before servicing, allow unit to cool.
WARNING
: ALWAYS SHUT OFF
ELECTRICITY WHEN WORKING ON UNIT.
This will prevent any electrical shocks or burns.
4. Ground the unit to prevent electric shock. All
electrical wiring should be in accordance with the
National Electric Code.
5. Duct work must be installed in accordance with
the standards of the National Fire Protection
Association (NFPA) for the installation of Air
Conditioning, Warm Air Heating and Ventilating
Systems (NFPA 90A
and 90B). Duct work in
non-conditioned spaces must be insulated to
prevent formation of condensate and for
maximum efficiency.
6. The safety testing agency labels appear on the
unit’s cover and the factory installed coil (if
provided) only. It does not cover any other
equipment. Exterior surface of cabinet may sweat
when units is installed in a non-conditioned space
such as an attic or garage. Installer must provide
protection such
as full size auxiliary drain pan on
all units installed in a non-conditioned space to
prevent damage from condensation runoff. It is
recommended that units installed in non-
conditioned spaces be insulated with 1” thick
fiberglass with the vapor barrier on the outside.
7. While designed to operate quietly when properly
installed, several steps should be taken insure this.
Use of isolation pads when mounting unit,
flexible d
uct collars for discharge, and use of
acoustical duct liners are all good installation
practices that promote quite operation.
8. Cabinet insulation is rated for R-4.2 (standard).
Some jurisdictions require R-6.0 on installations
in a non-conditioned space. To achieve R-6.0,
add insulation 1” thick to exterior of the unit
to comply in these jurisdictions, putting the
vapor barrier on the outside.
WARNING:
Hot water can scald. Water heated to a temperature
which will satisfy space heating can scald and
permanently injure a person upon contact. Some people
are more likely to be permanently injured by hot water
than others. These include the elderly, children, the
infirm, physically or mentally handicapped.
Check local, State, and National codes requiring a
certain temperature water at the hot water tap. Special
precautions must be used in addition to us
ing the lowest
possible temperature setting that satisfies your hot water
needs. A Tempering device such as a mixing valve,
should be used at the hot water taps, or water heater.
UNPACKING THE UNIT:
The unit should be unpacked on receipt and if any damage
is found, follow the instructions under the “INSPECTION”
section of this manual.
This air handler is completely assembled. (NOTE: Electric
heat can be ordered as field installed, if field
installed, refer to the sep
arate installation instructions
provided with the heater kit.) Only electrical power,
thermostat wiring, hot water piping (if applicable) and
duct connections are needed for installation. DX coils will
also require refrigerant and condensate drain connections.
Some units may have motor supports over the motor shaft.
Remove these supports as necessary.
MINIMUM CLEARENCES:
These units have a 0” minimum clearance to combustible
materi
als rating from all cabinet surfaces. The unit should
be installed with serviceability clearance of 30” from the
front of the unit. The unit can be serviced entirely from the
front, including replacing the filter. Be sure to route
primary and secondary condensate drain piping so that it
does not obstruct replacement of the filter.
ARRANGEMENT:
Unit is shipped from the factory for installation in a vertical
upflow or horizontal right to left air flow position
(standard) or field convertibl
e to a horizontal left
to right air flow position.
