INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Your ventilation system should be installed in conformance with the appropriate provincial or state
requirements or in the absence of such requirements with the current edition of the National
Building Code, and / or ASHRAE’s “ good Engineering Practice”.

IMPORTANT -

PLEASE READ THIS

MANUAL BEFORE INSTALLING UNIT

CAUTION - Before installation, careful consideration must be given

to how this system will operate if connected to any other piece of
mechanical equipment, i.e. a forced air furnace or air handler, oper­ating at a higher static. After installation, the compatibility of the two
pieces of equipment must be confirmed by measuring the airflow’s of
the Heat / Energy Recovery Ventilators.
It is always important to assess how the operation of any HRV/ERV
may interact with vented combustion equipment (i.e. Gas Furnaces,
Oil Furnaces, Wood Stoves, etc.).

NEVER - install a ventilator in a situation where its normal opera-

tion, lack of operation or partial failure may result in the backdrafting
or improper functioning of vented combustion equipment!!!

HRV-XI 450

Light Commercial HRV

The HRV-XI 450 Heat Recovery Ventilation system (HRV)
complements the energy efficiency of the modern building by
filtering incoming fresh outdoor air before it enters the heat­recovery core where it is preheated by the outgoing, stale
contaminated air. The HRV then distributes the preheated
fresh filtered air throughout the building by direct ductwork
installed specifically for the HRV or through the ductwork of
a forced-air system.

APPLICATIONS INCLUDE:

• Class Rooms • Offices

• Retail Shops • Clinics

• Hair Salons • Animal Shelters

• Bars & Restaurants • Large Homes

SPECIFICATIONS

CASE 20 gauge galvanized steel. Baked powder coated paint,

grey. Insulated with 1" (25 mm) foil-face fiberglass insulation
to prevent condensation. Two (2) drain connections 1/2"
NPT.

BLOWERS Two ebm™ direct drive external rotor blowers
with forward curved blades. Blowers come with permanently
lubricated sleeves for smooth and quiet operation. Blowers
come pre-wired with 4 speeds, three of which are available
to the installer as standard. Blowers are electrically
connected with a quick connect for quick and easy
inspection of blowers.

CORES Two (2) modular polyproplene heat recovery cores
configured for an efficient cross-flow ventilation. Each core
is 12" x 12" (305 x 305 mm) with a 15" (380 mm) depth.
Cores are manufactured using silicone to withstand extreme
temperature variations. (Aluminum cores are optional.)

FILTERS Four (4) Washable Electrostatic Panel Type Air
Filters, 11.75" (298mm) x 15" (380mm) x 0.25" (6mm)

MOUNTING Unit can be installed using the four (4)
mounting brackets included. Brackets fasten to HRV (bolts
provided) and to floor joists using wood screws, not
provided. Unit may also be suspended by using the supplied
brackets and threaded rod, not supplied, or placed on a
platform.

CONTROLS Low voltage (24VAC) external dry contacts to
activate high speed. External three (3) position switch for
LOW/STAND BY/ MED continuous ventilation speeds.

DEFROST A preset 5 minute defrost sequence is activated at
an outdoor air temperature of 23˚F (-5˚C) and lower. During
the defrost sequence, the supply blower shuts down & the
exhaust blower switches into high speed to maximize the
effectiveness of the defrost strategy. The unit then returns to
normal operation for 25 minutes, and continues cycle.

SERVICEABILITY Cores, filters and drain pans can be
accessed easily from both sides of the HRV from hinged
access panels. Cores conveniently slide out with only 15

"

(380mm) clearance. Blowers can be accessed from both
sides of the HRV from fastened access panels. Blowers are
easily removed by removing the access panel and sliding the
motor plates out of the HRV. A quick connect allows for fast
inspection of blowers.

ERV-XI 450

Light Commercial ERV

The ERV-XI 450 lowers demand on air conditioning systems.
Air supplied from outdoors enters through the Energy
Recovery Core where it transfers the heat and humidity to the
exhaust air . The air supplied by the ERV-XI 450 is now cooler,
dryer and more comfortable. The ERV-XI 450 distributes the
pre-conditioned fresh filtered air throughout the building by
direct ductwork installed specifically for the ERV or through
the ductwork of a forced-air system.
