HEAT EXCHANGER REMOVAL OF
SINGLE- MOTOR UNIT HEATER
1. Remove unit heater from its mounted location and
lower to a stable working surface.
2. Remove all louver blades from the front of
the cabinet.
3. Remove the left fan guard and left cabinet
side panel as described below. If the heat exchanger
has flanged connections, also remove the top
cabinet panel.
4. Support the weight of the heat exchanger by the
piping connection while removing the four core bolts
that fasten the heat exchanger to the cabinet. (See
figure 9). Allow heat exchanger to rest on the bottom
of the cabinet.
5. Remove the two bolts holding the motor mount to
the left side of the cabinet. Support motor mount while
removing these two bolts. Once cabinet side has
been removed, reinsert the bolts in the motor
mount. Place a support under the motor mount to
prevent the cabinet from rolling over during heat
exchanger removal (see Figure 12).
6. With the cabinet side removed and motor mount
supported, slide heat exchanger out of the cabinet.
(see Figure 13). On larger units, assistance may be
necessary due to the weight of the heat exchanger.
7. To install heat exchanger into cabinet, reverse order
of heat exchanger removal procedure.
HEAT EXCHANGER REMOVAL OF
DOUBLE-MOTOR UNIT HEATER
(Due to the weight of the heat exchanger, an assistant is
recommended to help with the following procedure.)
1. Remove unit heater from its mounted location and
lower to a stable work surface. To prevent damage to
the bottom piping connection, do not rest heater on
connection while servicing.
2. Remove all louvers from the front of the cabinet.
3. Remove the top cabinet panel by removing the four
bolts in the corners of the top panel and the fasteners
along the top of the shrouds (see Figure 14).
4. Have an assistant support the weight of the heat
exchanger while removing the eight bolts that fasten
the heat exchanger to the cabinet (see Figure 15).
Once the bolts on one side are removed, lower that
side of the heat exchanger to rest on the bottom of
the cabinet. Place a support under the motor mount
of the cabinet to prevent the cabinet from rolling over
during heat exchanger removal (see Figure 14).
5. Loosen cabinet side panel fasteners but do
not remove. If the heat exchanger has flanged
connections also remove the left side panel.
6. Lift the heat exchanger up and out through the front
of the cabinet (see Figure 16).
7. To install heat exchanger procedure, reverse the
order of heat exchanger removal procedure.

G.2 Retrait de l'échangeur de chaleur d'une unité de
chauffage monomoteur
1. Retirez le système de chauffage de son logement et
déposez-le pour obtenir une surface de travail stable.
2. Retirez toutes les lames des ventelles de la partie avant de
l'armoire.
3. Retirez la grille gauche du ventilateur et le panneau
latéral gauche de l'armoire, comme décrit ci-dessous. Si
l'échangeur de chaleur est équipé de raccords à brides,
retirez également le panneau supérieur de l'armoire.
4. Soutenez le poids de l'échangeur de chaleur au moyen du
raccord de tuyauterie, tout en retirant les quatre boulons
centraux qui maintiennent l'échangeur de chaleur à
l'armoire. (voir Figure 8, page 34). Laissez l'échangeur de
chaleur reposer sur la partie inférieure de l'armoire.
5. Retirez les deux boulons qui maintiennent le support
moteur sur le côté gauche de l'armoire. Soutenez le support
moteur tout en retirant ces deux boulons. Une fois le côté
de l'armoire retiré, replacez les boulons dans le support
moteur. Placez un soutien sous le support moteur pour
éviter que l'armoire ne se renverse pendant le démontage
de l'échangeur de chaleur (voir Figure 11, page 34).
6. Une fois le côté de l'armoire retiré et le support moteur
maintenu, faites glisser l'échangeur de chaleur hors de
l'armoire. (voir Figure 13). Sur les grandes unités, le poids
de l'échangeur de chaleur peut requérir une assistance
supplémentaire.
7. Pour installer l'échangeur de chaleur dans l'armoire,
procédez dans l'ordre inverse de sa procédure de retrait.
G.3 Retrait de l'échangeur de chaleur d'une unité de
chauffage bimoteur
(En raison du poids de l'échangeur de chaleur nous vous conseillons
de faire appel à un assistant pour la procédure suivante.)
1. Retirez le système de chauffage de son logement et
déposez-le pour obtenir une surface de travail stable. Pour
éviter d'endommager le raccord inférieur de la tuyauterie,
ne posez pas l'appareil de chauffage sur le raccord lors de
l'entretien.
2. Retirez toutes les ventelles de la partie avant de l'armoire.
3. Retirez le panneau supérieur de l'armoire en enlevant les
quatre boulons situés aux coins du panneau supérieur,
ainsi que les fixations le long de la partie supérieure des
capots (voir Figure 13).
4. Demandez à un assistant de supporter le poids de l'échangeur
de chaleur et retirez les huit boulons qui maintiennent
l'échangeur de chaleur à l'armoire (voir Figure 14). Une fois les
boulons retirés d'un côté, abaissez ce côté de l'échangeur de
chaleur pour qu'il repose sur la partie inférieure de l'armoire.
Placez un soutien sous le support moteur du cabinet pour
éviter que l'armoire ne se renverse pendant le démontage de
l'échangeur de chaleur (voir Figure 13).
5. Desserrez les fixations des panneaux latéraux de l'armoire,
mais sans les enlever. Si l'échangeur de chaleur est équipé
de raccords à brides, retirez également le panneau gauche
de l'armoire.
6. Soulevez l'échangeur de chaleur vers le haut et le sortir par
l'avant de l'armoire (voir Figure 15).
7. Pour installer l'échangeur de chaleur, procédez dans
l'ordre inverse de sa procédure de retrait.
