MECHANICAL SPECIFICATIONS
General
ERV indoorunits are factory assembled and provided with an
internally mounted control circuit board, exhaust fan, supply fan,
cross-flowairto airheat exchanger, washable outdoorairand return
airfilters, and bypass damper. Each unit is designed to operate
using 208-230/60/1 power with voltage variances of ±10%. ERV
operation range is 14°F - 113°F outdoortemperature.
Casing
The metal casing is designed to mount concealed above a finished
ceiling. Supply fan discharge and exhaust fan inlet (return air)
are front horizontal. Supply fan inlet (outdoorair) and exhaust fan
discharge are rearhorizontal. Cold metal surfaces are externally
insulated. The case is provided with hangerbrackets designed
to support the unit weight on forcorners. Hangerbrackets have
pre-punched holes designed to accept field supplied, all-thread rod
hangers.
Fan Assemblies
ERV units have two fans; one fan forsupply airand one fan for
exhaust air. Both fans are direct driven. Fan motors are brushless,
digitally-controlled (BLDC) design with permanently sealed
bearings. The fan/motorassemblies are mounted in vibration
attenuated rubbergrommets. The fan speeds are controlled using a
microprocessor-based direct digital control algorithm that provides
three fan speeds. Fan speeds are superhigh, high, and low. Each
fan speed can be adjusted from the factory setting using external
static pressure (ESP) control settings to change fan speeds to
compensate forairflow resistance caused by field installed ductwork.
Cross flow Air-to-air Heat Exchanger
Cross flowair-to-airheat exchangeris constructed of non-
flammable, specially processed paperthat allows transferof heat
and humidity. The air-to-airheat exchanger recovers energy from
indoorairas it is exhausted outdoors. The recovered energy is
transferred to the in-coming outdoorair without mixing airstreams.
Ahinged access panel allows removal of air-to-airheat exchanger
forvacuum orbrush cleaning. Since both heat and humidity are
transferred, condensate drain is not required.
Air Filter
Two washable mesh filters are provided at the outdoorairand return
airinlets of the air-to-airheat exchanger.
Microprocessor Controls
The ERV is provided with an integrated microprocessor-based
controller. All unit operation parameters, excluding the unit operating
schedule, are stored in non-volatile memory, resident on the ERV
microprocessor. Operating schedules are stored in the wall
controllerorcentral controller. ERV units can be operated
independently with a wall controllerorinterlocked to a Multi V
system. When interlocking to a Multi Vsystem, the field supplied
communication cable between the ERV and outdoorunit is to be
a minimum of 18 AWG, 2-conductor, stranded, and shielded cable
(RS485), terminated via screw terminals on the control board. The
microprocessorcontrol provides the following functions:
• Auto restart following power restoration
• External static pressure (ESP) control of fans
• ERV mode allowing airto pass thru air-to-airheat exchanger
• Bypass mode allowing exhaust airto bypass air-to-airheat
exchanger
The control board is also provided with terminals forconnection of a
field supplied CO2 sensor. DIP switch settings on the control board
allowthe ERV to operate independently oras a slave to a Multi V
indoorunit.
Due to our policy of continuous product innovation, some specications may change without notication.

Energy Recovery Ventilator Engineering Manual

ERV BENEFITS
Ventilation
Ventilation is a process that allows users to exchange indoorair
with outdoorairin orderto improve the airquality and to maintain
environmental temperature conditions. The Energy Recovery
Ventilation (ERV) system reduces the temperature and humidity of
incoming outside air. A balance is achieved between indoorand
outdoorambient which enables the cooling orheating load placed
on the airconditioning system to be reduced. It can be controlled
individually oras an integral part of the airconditioning system.
Benefits
The ERV system provides efficiency, cost savings, superior
performance, compact and light design, linear E.S.P control and
easy maintenance. The ERV system is ideal forhotels, dormitories,
restaurants,hospitals, retail establishments, theaters, schools, and
office buildings.
ZE ChassisZF Chassis
Energy Savings
The indoorairis passed through the heat exchangerto pre-warm or
pre-cool the incoming outside air which saves energy and money.
Design
Acoustically engineered and tested forquiet operation.
Easy Maintenance
Offers easy filter replacement and heat exchangercleaning.
