Qmark ECP Series - Euro Style Wall Heaters - Manual (Page 3)

(Optional)
Wall Surface Mounting Frame
(See Figure 3).
1. Remove heater assembly from back box by removing the
four mounting screws on the sides.
2. Secure back box to wall with knockouts in lower left cor-
ner using screws and anchors. Back box should be
mounted no closer than 3” (76 mm) from floor, 12” (305
mm) to adjacent walls and 18” (458 mm) to the ceiling.
NOTE: If heater is located in a high traffic area where it
may be subjected to vandalism or abuse, take extreme
care to see that the box is firmly attached to the wall.
3. Power Supply Wiring
NOTE: Wire Compartment Volume – 24 in 3 (386 cm 3 )
a. Run a power supply cable into the area of the lower
left corner of the surface mounted back box. All wiring
into the heater must be from the bottom or side of the
surface mounted back box. Do not route field wiring
into the back of the surface mounted back box. All
wiring must be in accordance with national and local
electrical codes. Refer to Table 1 for correct wire size.
b. Remove the wiring compartment cover located in the
lower left corner of the back box.
c. Remove the selected knockout in the bottom left cor-
ner or side of the back box. Insert properly protected
power supply cable into the heater allowing at least 6”
(152 mm) of leads to extend inside the back box.
d. Ground the back box by connecting the supply ground
leadwire to the green ground screw located inside the
lower left corner of the back box. Connect the two
leadwires on the socket connector attached to the
wiring cover assembly to the power supply leads using
approved connectors.
e. Gently push wiring into the wiring compartment and
attach wiring compartment cover to back box. Make
sure wiring is not protruding or being pinched between
the wiring compartment cover and the back box.
Installation of Heater Assembly and Grille
After back box is completely installed and wired and no further
construction dirt is expected, clean debris from back box.
1. Plug heater assembly into mating socket in back box
wiring cover. The plug and socket are “position sensitive”
so care should be taken regarding orientation.
Attach
heater assembly to back box using the four screws used
during removal.
2. Mount front grille by aligning the two grille tabs with the top
slots in the heater frame assembly. Attach the bottom of
the grille to the heater frame assembly using the screw
provided (taped to the front bottom of the heater frame.)
Operation
The heater is intended to be turned on and off by a remote line
voltage thermostat or some other controlling means suitable
for interrupting power to the heater.
1. Turn power to heater on at main switch panel.
Turn
remote line voltage thermostat to demand heat. This
should energize the heating elements causing convective
heated air to flow from the air discharge grille on the top
face of the grille. This may take a minute to be noticeable
and will increase in temperature with time.
2. After the discharge air has become warm and room con-
ditions become comfortable, adjust the remote wall ther-
mostat to the desired position to obtain room comfort.
IMPORTANT INFORMATION
Cleaning and Maintenance
The heater should be cleaned annually to remove dust and
other foreign material that has collected during the heating
season. This is a simple operation when performed as fol-
lows:
1. Turn off the electric power at main line switch (or remove
all fuses) to disconnect electric power to the heater. THIS
IS IMPORTANT.
2. Remove the grille (Figure 4).
3. With a vacuum cleaner nozzle or dust cloth, remove dust
and other foreign material from the heater and grille.
4. After cleaning, reinstall the grille.
5. Turn on the main line switch (or replace fuses) to restore
power to the heater. The heater is now ready for another
season of operation.
6. The exterior surfaces should be wiped down with clean
damp cloth. Avoid using harsh solvents and products
leaving oil or wax residue.
