7. Equipment Sizing 7A. Air Handler Selection
Select an air handler with a heating output that exceeds the space heating loss of the structure and that has a cooling coil sized to match the outdoor condensing unit. Special note... the heating output of the air handler or hot water coil will not be greater than the output of the selected hot water heater. Therefore, if the water heater is undersized the heating BTUH of the air handler will be LESS than it's rated output.

8. Installation 8A. Product Location
In an attic installation, where unit is resting on the floor, a suitable isolation pad should be provided to minimize equipment sound transmission to ceiling below.
FURTHERMORE, IN ALL COOLING APPLICATIONS, A SECONDARY DRAIN PAN MUST BE PROVIDED BY THE INSTALLER AND PLACED UNDER THE ENTIRE UNIT WITH A SEPARATE DRAIN LINE PROPERLY SLOPED AND TERMINATED IN AN AREA VIS-
ABLE TO OWNER. THIS SECONDARY PAN CAN PROVIDE EXTRA PROTECTION TO THE AREA UNDER THE UNIT SHOULD THE PRIMARY DRAIN PLUG UP AND OVERFLOW. AS EXPRESSED IN OUR PRODUCT WARRANTY, ASPEN WILL NOT BE BILLED FOR ANY STRUCTURAL DAMAGE DUE TO THE FAILURE TO FOLLOW THIS INSTALLATION REQUIREMENT.
8B. Installation Notes
This unit must be installed in accordance with all local and national codes. The furnace is completely serviceable from the front. All Units are approved for 0'' clearance. This Electric Furnace allows substantial freedom in positioning the product to best serve the structure requirements. Units may, without field modification, be positioned for upflow, horizontal left or horizontal right installation. The downflow position requires a slight field modification.
8C. Horizontal Application
Pitch unit 1/4" toward drain side.
It is recommended that wherever supply and return air sheet metal duct pass through unconditioned areas, they be insulated to prevent excessive heat loss during heating operation. When applied in conjunction with summer air conditioning, sheet metal duct routed through unconditioned areas should be insulated and have an outside vapor barrier to prevent formation of condensation.
8E. Electrical Installation
These units are designed for single or three phase 208/230 volt 60 Hertz power supply. Wire selection and wiring must be in accordance with the National Electric Code and/or local codes. Unit terminals are designed to accommodate copper and aluminum wiring. If aluminum wiring is used, please observe the special precautions relative to sizing, handling, wire connections and corrosion protection. All models with 5, 8, or 10 KW electric heat are arranged for single circuit connection. Models larger than 10 KW are arranged for multicircuit connection.All information needed to connect the 208/240VAC supply and 24VAC control wiring is supplied with the unit. Two knockouts are located for connection of power and control wiring. Since this unit is supplied with a 24 volt Class 2 transformer, a thermostat with isolating contacts must be used when connecting other add-on equipment using a Class 2 transformer.

8D. Duct Installation
Air duct systems should be installed in accordance with standards for air-conditioning systems, National Fire Protection Association Pamphlet No. 90A or 90B. They should be sized in accordance with National Environmental System Contractors Association Manual K, or whichever is applicable.
On any job, non-flammable flexible collars should be used for the return air and discharge connections to prevent transmission of vibration. Although these units have been specially designed for quiet vibration-free operation, air ducts can act as soundboards and could, if poorly installed, amplify the slightest vibration to the annoyance level.
8F. Special Instructions For Counterflow Applications (AEL)
The AEL Series Electric Furnace is specifically designed for the use in the upflow, horizontal and counterflow positions. Should the application be for counterflow position, the following steps should be taken:
1) Some units are supplied with factory installed circuit breakers. If the air handler has circuit breakers, they must be snapped out of the factory installed bracket and inverted to reflect "up" as the "on" and "down" as the "off" position.
All main supply and return air drops should be run full size as determined by the designer of the duct system and should not necessarily be the size of the duct flange openings of the unit
2) The above procedure should be done at the job site, as the unit is not designed to be shipped in the counterflow mode.
When installing a central air return grille in or near the living space, it is advisable to design the ductwork so that the grille is not in direct line with the opening in the unit. One or two elbows and acoustical duct liner will also assure a quieter installation and system.

9. Start Up
After all connections are made, start up and check out of the unit must be performed before proper evaluation of the entire system can be made. Make sure that heat anticipator is properly set as noted on low voltage wiring diagrams. Load requirements can vary in each residence and it may be necessary for the installer or homeowner to make slight adjustments to the heat anticipator setting for longer or shorter cycles. It is recommended to change the setting no more than plus or minus .05 amps at one time. Greater changes can cause the unit to rapid cycle or remain on excessively. To properly check the unit's operation, the installer should have an electrical current measuring device (0-10 amp Amprobe), air pressure measuring device (0-1.0 in slope gauge), and a temperature-measuring device (0-200ºF thermometer).
Install the amprobe to measure blower current, the slope gauge to measure static air pressure at the units and the temperature device to measure unit supply and return air temperature. Before taking measurements, be sure that all registers, grilles and dampers are open or are set to their proper positions. Be sure that clean filters are in place. Temperature measuring device must be installed to obtain average temperature at both inlet and outlet. For outlet, measure temperature of each main trunk at a location far enough away to avoid heater radiation and read the average temperatures.
Do not store combustible materials or use
! WARNING gasoline or other flammable liquids or vapors in the vicinity of this appliance.
! CAUTION
Do not operate the comfort equipment with panels removed.
Have your contractor point out and iden-
! WARNING tify the various cutoff devices, switches, etc., that serve your comfort equipment. There is a main switch that will cut off energy to your heating system. Know where they are so that you may cut off the flow of energy in the event of overheating.
10D. Periodic Checkup and Service
This product is designed to provide many years of dependable, trouble free comfort when properly maintained. Proper maintenance will consist of annual checkups and cleaning of the internal electrical and heat transfer components by a qualified service technician. Failure to provide periodic checkup and cleaning can result in excessive operating cost and/or equipment malfunction.
10. General Operation And Maintenance
10A. Room Thermostat
This is the device that controls that operation of your heating and/or cooling unit. It senses the indoor temperature and signals the equipment to start or stop maintaining the temperature you have selected for your comfort. The room thermostat should be in a central, draft free inside wall location for best operation. Do not place any heat producing apparatus such as lights, radio, etc., near the thermostat as this will cause erratic operation of the comfort system. The thermostat can accumulate dust or lint, which can affect its accuracy. It should be cleaned annually.
10B. Air Filter(s)
All central air moving comfort systems must include air filter(s). These filters will be located either in the equipment or in the return air duct system upstream of the equipment. The filter(s) removes dust and debris from the air thus helping to keep your air conditioned space clean. More important, the filter keeps dust and debris from collecting on the heat transfer surfaces thus maintaining optimum equipment efficiency and performance. Inspect and clean or replace filters every month. This routine maintenance procedure will pay big dividends in reduced operating cost and reduced service expense. Never operate comfort equipment without filter(s).
An air filter can restrict the airflow of air to the fan coil if it is not cleaned or replaced periodically. When replacing the air filter, always replace with the same type and size as originally furnished with the unit.
10C. Fuses and/or Circuit Breakers
This comfort equipment should be connected to the building electric service in accordance with local and National Electric codes. This electrical connection will include over current protection in the form of circuit breakers. Have your contractor identify the circuits and the location of over current protection so that you may be in a position to make inspections or replacements in the event the equipment fails to operate.
10E. Lubrication
Direct drive blower motors are equipped with permanently lubricated bearings and do not require further lubrication.
11. Checking Air Flow/Temperature Rise Method
1. Turn on power supply. Set thermostat fan switch to on. Set the cooling indicator to maximum, heating to minimum. System switch may be on heat or cool. Check slope gauge measurement against appropriate air flow chart. Make damper, register and motor speed adjustments to obtain required airflow.
2. Set thermostat fan switch to auto, system to heat and thermostat heating indicator to maximum heat. Blower should start and all heat be energized.
3. Check air flow using temperature rise method.
OUTPUT (BTUH ) CFM =
1.08 ·TEMP.RISE
NOTE: BTUH output should be computed by VOLT x AMPS x 3.4 = BTUH OUTPUT. Since line volt can vary, do not use nameplate rating to determine output.
