2 MODE E CETRA EECTRIC WARM AIR FURACE GEERA ISTRUCTIOS It is the responsibility of the consignee of the unit to examine the package for damages and, if found, to note the same on the Carrier's Bill of ading. The furnace is shipped in one package. This includes the furnace assembly complete with elements, controls, blower, motor and casing, filter rack, filters, thermostat and instruction booklet. The furnace has 0 volt elements and for 0volt, wire, 0 volt blower motor, or 0/0volt, wire, 0 volt blower motor. All furnaces are phase, 0 z. See furnace label and this manual for more details.

CEARACE TO COMBUSTIBES The ewmac E Electric Furnace may be installed in the up-flow, down-flow, horizontal-left or horizontal -right positions with the following clearances to combustibles: Sides 0" Rear 0" Front (For Servicing) " Warm Air Plenum and Duct 0" cate the furnace to provide: Best heat distribution Shortest supply cable east interference with present or future plans. ISTA TO CODE This furnace shall be installed in accordance with the CSA Standard C., Canadian Electric Code, and the requirements of the authority having jurisdiction. These instructions are intended as a general guide and do not supersede local codes. Consult local authorities before installation. POWER CABE Use 7 C copper supply sized according to the minimum ampacity. This should be connected to a separate fused disconnect switch to power the furnace. Suitable ground must be provided.

3 RETUR AIR AD FITER RACK The filter rack may be mounted on either side, the bottom or the back of the appliance. Position the rack so that there is easy access to change the filter. WARM AIR Before installing the plenum, look into the furnace and check the heating elements to ensure that no damage has occurred and that they are free of foreign material. TERMOSTAT and ATICIPATOR Should be installed according to the instructions packed with it and connected to the volt terminals on the front of the appliance. The heat anticipator should be set to 0. amps. BOWER SPEED AD STATIC PRESSURE The ewmac E Electric Furnace is tested and approved by CSA for static pressures of 0.0 to 0.0 ins wc. The 0.0 ins wc static pressure setting is for normal use and the units are factory equipped with the blowers set to provide this. The 0.0 ins wc static pressure setting is for air conditioning. The installer should set the required blower speed - see table below. Set the speed of the belt-drive-blower units by adjusting the motor pulley. Adjust this pulley to give the recommended air temperature rise. SEQUECE OF OPERATIO As the room temperature drops, the thermostat contacts will close and energize the heating element on the first sequencer. After approximately 0 seconds, the first set of contacts in the sequencer will close, bringing on the # element. At the same time the circulating blower will start. After approximately 0 seconds, the # element will come on. Depending on the model, and if the furnace is set to i, #, #, #, and # elements will come on in sequence. See below for more information on the i/econo switch setting. When the room thermostat is satisfied, it will break contact. All the elements will turn off in random sequence. The blower will stop when the last element shuts off. I/O COTIUOUS FA SWITC This is located on the front of the furnace and provides the homeowner with the option of having the circulating blower run continuously at high or low speed. This control does not affect the normal heating and cooling cycles of the furnace. I/ECOO EAT SWITC This switch is provided on some models. It is located on the front of the furnace and provides the homeowner with the option of manually increasing or reducing the heating power of the furnace. It can be used to manually switch from "i" to "Econo" if less heating power is temporarily desired, depending on the outdoor temperature. This switch can also be controlled automatically by a suitable multi- or two-stage thermostat connected to the W (Econo) and W (i) terminals. Set the switch to "Econo" if a two stage or multi-stage thermostat is used. If a standard thermostat is connected across W- R, a remote switch or an outdoor temperature switch can be connected across OT-W to switch from "Econo" to "i" as the outdoor temperature drops. eave the furnace switch in "Econo" if a remote or outdoor temperature switch is used.

OMEOWER If you, the homeowner, suspect the furnace is not operating properly, or if there is no heat, do not tamper with the furnace. ave a qualified service person check out the furnace installation. BOWER REMOVA Turn off the main electricity power supply before servicing the furnace. Open the centre access panel to disconnect the wiring to the blower motor Open the blower access panel. Carefully unscrew the bolt(s) holding the blower assembly in place, and remove the entire blower/motor assembly by sliding it out through the access opening.
