Disconnect the power from the unit before cleaning or servicing.
To prevent electrical shock, it is extremely important to confirm the polarity of the power line that is switched by
the safety (disconnect) switch. The hot line (black) is the proper line for switching. Use either a voltmeter or test
lamp to confirm the absence of a voltage between the disconnect switch and ground (on the cabinet) while the
door is open. This procedure must be followed, as dwellings are occasionally wired improperly. Always ensure the
proper grounding of the unit.
Warning
Due to ongoing research and product development, specifications, ratings, and dimensions are subject to change
without notice. Refer to www.LIFEBREATH.com for the latest product information.

Selecting the Ventilation Rate That is Right for You
The modes of operation and speeds are used to adjust your indoor ventilation rate. Experiment with the
ventilation levels in your home to evaluate the ideal amount of ventilation to suit your home and
personal preferences. Operational modes available to you will depend on the main control that is installed.
Some features and modes may be unavailable to you.
Recirculation
Recirculates existing household air without introducing fresh air. Recirculation modes (II and V) are not
applicable if your HRV is connected to a forced air system, since your forced air system already circulates the
household air. Recirculation modes are unavailable on some models.
I. Continuous Ventilation
This mode of operation provides continuous ventilation within the home. You may, for example, select
Continuous Ventilation at low speed for normal operation and increase to high speed during increased
activity levels, such as cooking and showering, etc.
II. 20 Minutes On, 40 Minutes Recirculation 20/hr 40/hr
This mode ventilates for 20 minutes and recirculates the household air every 40 minutes each hour. This
mode is not applicable if your HRV is connected to a forced air system.
III.20 Minutes On, 40 Minutes Standby 20/hr 40/hr
This mode of operation provides 20 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied.
IV. 10 Minutes On, 50 Minutes Standby 10/hr 50/hr
This mode of operation provides 10 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied. This mode is useful when
20/40 mode is providing too much ventilation.
V. Continuous Recirculation or
This mode continuously recirculates your household air (no ventilation). This mode is not applicable if your
HRV is connected to a forced air system.
VI. Continuous Low Fan Speed LO
This mode will operate the fan in low speed continuously at the selected operating mode (Ventilation or
Recirculation).
VII. Continuous High Fan Speed HI
This mode will operate the fan in high speed continuously at the selected operating mode (Ventilation or
Recirculation). This mode is useful when occupancy in the home or activity is high for an extended period
of time.

How the Dehumidistat Works
Only the DXPL02, BC02 and BC03 controls are equipped with an adjustable Dehumidistat.
High indoor humidity levels, during the heating season, have become a problem in many well
insulated, tight homes, excessive condensation on the window is a visual sign of high indoor
humidity levels. High indoor humidity levels can result in mold and mildew and the eventual
degradation of the building structure itself.
Your HRV reduces indoor humidity levels when the outdoor air is drier than the indoor air. These
conditions usually occur during the heating season when outdoor temperatures are less than 15oC
(59oF). During the heating season, the operation of the HRV may reduce indoor humidity levels
sufficiently to eliminate the need for further dehumidification. If your home requires further
dehumidification, use the Dehumidistat feature if available located on the main control. This
feature aggressively addresses high indoor humidity levels by initiating high speed ventilation when
the indoor humidity levels rise above the adjustable set point on the control. Refer to the "Setting
the Dehumidistat" section of either the DXPL02, BC02 or BC03 control instructions on how to set
the Dehumidistat, depending on which control you have installed. The Dehumidistat function
should be set to off for all seasons except the heating season because a dehumidifying effect
occurs only when the outdoor air is dryer than the indoor air.
The DXPL02, BC02 and BC03 controls have an adjustable Dehumidistat which can be set to achieve
a further dehumidification effect from your HRV. High speed ventilation will be initiated upon
exceeding the Dehumidistat set point regardless of the mode and speed of operation. Once the
humidity in the house is reduced, the HRV will revert back to its previous setting.
We suggest operating the HRV for the first few days without use of the Dehumidistat function to
observe if a further dehumidification effect will be required. The Dehumidistat operates in % of RH
(relative humidity) with 60 being high and 20 being low. If after a few days, further
dehumidification is required (the house is still too humid), set the humidity level to a lower
amount.
The average person is comfortable between 30% and 50% RH. The Dehumidistat should be set to
off for all seasons except the heating season.
Dehumidistat Disable automatically disables the dehumidistat function on the main control when outdoor
temperatures exceed 15oC (59oF) for a full 24 hour period. All other HRV features and functions operate normally
while the dehumidistat function is disabled.
Dehumidistat Re-Enable automatically re-enables the dehumidistat function if either the outdoor temperature
drops below 15oC (59oF) for a full 24 hour period or if the HRV is reset (unplugged for 30 seconds).

Maintenance Routine
1. Inspect Exterior Hoods at Least Once a Month
Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass,
or snow. In winter, it is especially important to make sure snow is not blocking the hoods or
that frost has not built up on the wire mesh (bird screen).
2. Clean Air Filters (Clean Four times a Year)
The standard filters equipped with your HRV are removable and washable.
a) Open access door and slide core out.
b) Remove filter clips if present.
c) Once clips are removed, filters can be taken off the core to be rinsed with cold water or a
combination of mild soap and water. Do not wring out or clean in the dishwasher.
d) To re-assemble, place clean filter(s) (wet or dry) back into their positions against the core
and return clips to their original positions.
e) Slide core back into its original position.
3. Clean Core Twice a Year
a) Open access door.
b) Carefully grip ends of core and pull evenly outward. Core may be snug, but will slide out
of the cabinet.
c) Once removed from the cabinet remove filters.
d) Install the clean filters.
e) Install clean core in the cabinet.
Note: Core installation label on the outer end of the core.
To Install the Clean Core:
a) To reinstall the core first position the bottom of the core on the bottom support in the
cabinet.
b) Carefully align the core with the other 3 supports and fully insert the core.
c) Push on sides of core, do not push on the center.
Note: Core may appear to stick out from the cabinet approximately 1/8 in (3 mm). This is
designed this way so that the access door will fit tight against the core.
Do not use cleaning solutions for the HRV core
Soak and rinse the HRV core in warm soapy water
Do not use bleach or chlorine
Do not use a pressure washer on the HRV core
Do not place the HRV core in a dishwasher

Maintenance Routine Continued
4. Motors — Maintenance Free
5. Drain (condensate) Line - Clean Once a Year
Inspect drain line, drain spout and “P” trap for blockage, mold or kinks. Flush with warm
soapy water and replace if worn, bent or unable to clean.
6. Clean Duct Work if Required
The duct work running to and from the HRV may accumulate dirt. Wipe and vacuum the duct
once every year. You may wish to contact a heating/ventilation company to do this.
7. General Maintenance - Twice a Year
Wipe down the inside of the cabinet with a damp cloth to remove dirt, bugs and debris that
may be present.

Additional Information
Defrost Mode - During cold weather, the HRV automatically cycles through its defrost mode when
temperatures drop below freezing to avoid frost build up in the core.
HRV - a Heat Recovery Ventilator (HRV) is designed to provide fresh air into a building while
exhausting an equal amount of stale air. During the winter months, heat recovered from the stale
air, before it is exhausted to the outdoors, warms the incoming cold fresh air. During the summer
months, when the indoor space is air conditioned, the HRV helps to cool the incoming fresh air with
the cool exhausted stale air.
Self-Test - Each time the HRV is powered/energized, the self-test function automatically initiates.
The HRV cycles through the available speeds and tests the damper motor operation. The HRV
resumes operation at the selected mode and speed. (Approximately 60 seconds in duration.)
Standby (Speed 0) - The HRV is on but fans are not running waiting for Ventilation to be
initiated by either an external control (i.e. Timer) or the Dehumidistat. Set the main control to
speed 0 to set the HRV in standby.
Timers - These optional controls may be installed at specific exhaust locations (bathrooms etc.) to
initiate high speed Ventilation.

Renseignements additionnels
Mode de dégivrage - Pour assurer un fonctionnement fiable par temps froid, le VRC passe
automatiquement à son mode de dégivrage lorsque la température descend au-dessous du point de
congélation, afin d'éviter une accumulation de givre.
VRC - Le ventilateur à récupération de chaleur (VRC) est conçu pour fournir de l'air neuf dans un
édifice, tout en évacuant une quantité égale d'air vicié. Durant les mois d'hiver, l'air neuf et froid qui
arrive est réchauffé au moyen de la chaleur récupérée de l'air vicié avant son expulsion vers
l'extérieur. Pendant les mois d'été, alors que l'air intérieur est climatisé, le VRC aide à refroidir l'air
neuf qui arrive, grâce à la température plus basse de l'air vicié qui est évacué.
Auto-vérification - Chaque fois que le VRC est mis sous tension, la fonction d'auto-vérification est
automatiquement activée. Le VRC passe par toutes les vitesses disponibles et vérifie le
fonctionnement du moteur du registre. Le VRC revient ensuite à son mode de fonctionnement
antérieur et à la vitesse choisie (après environ 60 secondes).
Mode d'attente (Vitesse 0) - Le VRC est mis sous tension et attend que la ventilation soit
actionnée par l'intermédiaire d'une commande externe (par ex. une minuterie) ou du déshumidistat.
Réglez la commande principale à la vitesse 0 pour que le VRC soit en mode d'attente (standby).
Minuteries - Ces commandes optionnelles peuvent être installées à des points d'évacuation
spécifiques (salles de bains, etc.) afin de déclencher, le cas échéant, la haute vitesse.

 les registres, s'ils ont été posés, sont
fermés
 mauvaise alimentation électrique sur
les lieux
 les canalisations restreignent le débit
d'air
 commande de vitesse mal réglée
 débit d'air du VRC mal équilibré
 nettoyez les évents ou capuchons extérieurs
 retirez et nettoyez le filtre
 retirez et nettoyez le noyau
 vérifiez et ouvrez les grilles
 ouvrez et ajustez les registres
 demandez à un électricien de vérifier l'alimentation
électrique
 vérifiez la pose des conduits
 augmentez l'allure du VRC
 faites équilibrer le VRC par un entrepreneur
L'air qui arrive
semble froid  température extérieure extrêmement
froide  ralentissez l'admission du VRC  des meubles mal placés ou des portes fermées
empêchent l'air de circuler librement
 si l'air fourni est acheminé dans la chambre de retour de
la fournaise, il se pourrait que son ventilateur doive
tourner sans arrêt, afin de répartir confortablement l'air
de ventilation
Le déshumidistat
ne fonctionne pas  température extérieure au-dessus de
15ºC (59ºF)
 vérifiez le réglage du déshumidistat,
car il pourrait avoir été réglé à OFF
 le déshumidistat fonctionne normalement (voyez la
section sur la désactivation du déshumidistat dans le
manuel)
 réglez le déshumidistat au niveau désiré
Niveau d'humidité
trop élevé;
condensation sur
les fenêtres
 réglage trop haut du déshumidistat
 VRC pas assez puissant pour un "hot
tub", une piscine intérieure, etc.
 mode de vie des occupants
 humidité qui pénètre dans la maison
en provenance d'un espace sanitaire
non ventilé ou non chauffé
 l'humidité reste dans la salle de bain
et la cuisine
 il semble y avoir de la condensation
au printemps et à l'automne
 la vitesse prévue pour le VRC est trop
basse
 réglez le déshumidistat plus bas
 couvrez la piscine et le "hot tub" quand vous ne vous en
servez pas
 évitez d'étendre du linge à sécher, d'emmagasiner du
bois et de ventiler la sécheuse à linge à l'intérieur; vous
devrez peut-être sortir le bois de chauffage dehors
 aérez l'espace sanitaire et mettez un pare-vapeur sur le
plancher de cet espace sanitaire
 par temps humide, lorsque les saisons changent, il
pourrait y avoir un peu de condensation, mais la qualité
de l'air dans la maison demeure excellente quand on
utilise le VRC
 augmentez la vitesse du VRC
Degré d'humidité
trop bas  déshumidistat réglé trop bas
 trop grande vitesse de la soufflante
du VRC
 mode de vie des occupants
 débits d'air du VRC mal équilibrés
 réglez le déshumidistat plus haut
 faites ralentir la soufflante du VRC
 vous devrez peut-être employer des humidificateurs
 faites équilibrer la circulation d'air du VRC par un
entrepreneur
Formation de givre
dans le VRC et/ou
les conduites
 débits d'air du VRC mal équilibrés
 défectuosité du système de
dégivrage du VRC
 N.B. : il faut s'attendre à une légère accumulation de
givre sur le noyau, avant le déclenchement du cycle de
dégivrage
 demandez à un entrepreneur spécialisé d'équilibrer le
VRC
Condensation ou
accumulation de
glace dans la
conduite isolée
allant vers
l'extérieur
 pare-vapeur incomplet autour de la
conduite isolée
 trou ou déchirure dans le
recouvrement extérieur de la
conduite
 enrubannez et scellez tous les joints
 mettez du ruban adhésif sur les trous ou les déchirures
qui se trouvent dans le recouvrement extérieur de la
conduite, assurez-vous que le pare-vapeur est
complètement scellé
Trop d'eau dans le
fond du VRC
 bacs de drainage bouchés
 mauvais raccordement aux
canalisations d'écoulement du VRC
 le VRC n'est pas de niveau
 canalisations d'écoulement obstruées
 noyau échangeur du VRC mal installé
 voyez s'il y a des obstructions dans la canalisation
d'écoulement
 les tubes pourraient être tortillés
Vibration excessive  saleté sur le ventilateur rotatif  demandez à un entrepreneur d'entretenir le VRC
SYMPTÔME CAUSE SOLUTION

Entretien courant (suite)
4. Les moteurs n'exigent aucun entretien
5. Nettoyez le tube d'eau de condensation (drainage) une fois par année
Examinez le tube d'évacuation, la goulotte de vidange et le siphon en P en cas d'obstruction, de
moisissure ou de tortillement. Rincez bien le tube avec de l'eau savonneuse modérément chaude.
Remplacez-le s'il est trop usé, faussé ou impossible à nettoyer.
6. Nettoyez les canalisations au besoin
Il pourrait y avoir une accumulation de saleté dans les canalisations reliées au VRC. En plus de vous
servir d'un aspirateur, essuyez les canalisations une fois par année. Vous pourriez aussi confier cette
tâche à une entreprise spécialisée en chauffage et climatisation.
7. Effectuez un entretien général deux fois par année
Essuyez l'intérieur de l'armoire avec un chiffon humide, afin d'enlever la saleté, les insectes morts et
les débris qu'il pourrait y avoir.
