Advertencia especial para la instalación de calentadores ó manejadoras
de aire en áreas cerradas como estacionamientos ó cuartos de servicio.
Las emisiones de monóxido de carbono pueden circular a través
del aparato cuando se opera en cualquier modo.
El monóxido de carbono puede causar enfermedades severas
como daño cerebral permanente ó muerte.
RISQUE D'EMPOISONNEMENT AU MONOXYDE DE CARBONE
Cette ventilation est nécessaire pour éviter le danger d'intoxication
au CO pouvant survenir si un appareil produisant du monoxyde
de carbone continue de fonctionner au sein de la zone confinée.
General Information
The MBVC Blower Cabinets are used in combination with a cased
evaporator coil. This combination of blower and coil functions
as the indoor part of a split air-conditioning system, and may be
matched with a remote condensing or heat pump unit. The blower
cabinet can also function as an electric furnace when used with an
electric heater.
NOTE: The electric heating elements for electric furnace
installation are not shipped with the cabinet and are field-installed.
Systems should be properly sized by heat gain and loss calculations
made according to methods of the Air Conditioning Contractors
Association (ACCA) or equivalent. It is the contractor's responsi-
bility to ensure the system has adequate capacity to heat or cool
the conditioned space.
Features
This modular blower is a part of the ComfortBridge™ Technology
family of products. The Modular Blower can operate as a digitally
communicating system requiring only simple 24VAC thermostat in-
puts to function (Y for cooling, W for heating, G for fan operations).
Internal algorithms will provide 2 stage or inverter Air Conditioner
or Heat Pump functionality based on these simple inputs. With
built-in Bluetooth operation, the CoolCloud™ HVAC phone appli-
cation is available for commissioning, software and shared data
updates and troubleshooting. The Modular Blower can support
non-communicating outdoor unit installations as well. See wiring
sections for more details. The ComfortBridge™ Technology system
simplifies wiring, provides enhanced setup features and elevates
diagnostics capabilities.
Achieving Less Air Leakage:
Ensure all the gaskets remain intact on surfaces as shipped with the
unit. Ensure upon installation that the plastic breaker cover is flush
on with the access panel and access panel is flush with the cabinet.
With these requirements satisfied, the unit achieves less airflow
leakage when tested in accordance with ASHRE Standard 193.
•
Cabinet air leakage less than 2.0% at 1.0 inch H
tested in accordance with ASHRAE standard 193.
Cabinet air leakage less than 1.4% at 0.5 inch H
•
tested in accordance with ASHRAE standard 193.
Clearances And Accessibility
The unit can be positioned for upflow, counterflow, horizontal right
or horizontal left operation. Zero clearance is allowed on all sides
for combustible materials. Thirty-six inches should be allotted on
the door side for maintenance and service.
To reduce risk of rusting, do not install the unit directly on the
ground or on a floor that is likely to be wet. In such environments,
the unit must be elevated by use of a sturdy, nonporous material.
Insulation
To ensure efficient operation, review the following precautions.
•
If the unit is located in an area with high ambient
temperature and/or high humidity, the air handler may
be subject to nuisance sweating of the casing. On these
installations, a wrap of 2" fiberglass insulation with a vapor
barrier is recommended.
