As soon as the air handler is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier’s freight bill. A separate request for inspection by the carrier’s agent should be made in writing. Before installing the air handler you should check the cabinet for screws or bolts which may have loosened in transit. There are no shipping or spacer brackets that need to be removed before startup. See the local Distributor for more information. Lennox assumes no liability for freight damage. Also check to be sure all accessories such as heater kits, and coils are available. Installation of these accessories should be accomplished before the air handler is set in place or the connecting of the wiring, electric heat, ducts or piping.

Refrigerant pipe work must be done before installing the indoor unit.
ទីតាំង
Access to servicing is an important factor in the location of any air handler. Provide a minimum of 30 inches (762mm) in front of the appliance for access to the control box, heating elements, blower and air filters. This access may be provided by a closet door or by locating the appliance so that a wall or partition is not less than 30 inches (762mm) from the front access panel. Location is usually predetermined. Refer to the figure below. Check with the owner’s or dealer’s installation plans. If the location has not been decided, consider the following in choosing a suitable location. 1 Select a location with adequate structural support, space for service access, and clearance for return and supply duct
connections. 2 Normal operating sound levels may be objectionable if the air handler is placed directly over or under some rooms such as
bedrooms, study, etc. 3 Caution should be taken to locate the unit so that supply and return air ducts are about the same length causing even air
distribution of supply and return air to and from the living spaces. 4 Locate the appliance where electrical supply wiring can be easily routed to the main electrical panel and where electrical
wiring will not be damaged. 5 Locate the appliance where control wiring can be easily routed to the controller and where the wiring will not be
damaged. 6 Locate the appliance where refrigerant lines can be easily routed from the evaporator coil to the system. 7 Locate the appliance where condensate lines can be easily routed to an available drain. Be sure to route condensate drain
piping so as not to obstruct access to the air filter. 8 The coil is installed in a draw-thru application and will create a negative pressure situation in the condensate drain system.
To prevent condensate from being drawn into the blower it is recommended to trap the primary (Main) and secondary (Overflow) drain line. Refer to the Drain Pipe and Drain Hose section in these instructions. If the secondary drain is not used, it must be capped. This unit has a connection terminal for drain system monitoring. Refer to the Wiring Work section for information regarding the connection of field-provided condensate overflow devices in these instructions. 9 The draw-thru design will cause the exterior surface of the cabinet to sweat when the unit is installed in a nonconditioned space such as an attic or garage. The installer must provide protection such as a full size auxiliary drain pan on all units installed in a non-conditioned space to prevent damage from condensation runoff. Some states, cities and counties require additional insulation to be installed on the exterior casing of the air handler to prevent sweating. Refer to the state, city, county or local code for insulation requirements to be sure the installation complies. It is recommended that air handlers installed in non-conditioned spaces be insulated on the exterior of the entire cabinet, including the front access panel with one (1) inch (25.4mm) thick fiberglass with the vapor barrier on the outside. 10 Ensure sufficient space for the bottom of the product (H dimension) so that a downward slope of 1/100 can be maintained for drain piping, as described for the intake duct installation and in “Drain pipe installation”.

Return air requirements

ការដំឡើង

Return Air Requirements For the air handler to work properly, a closet or alcove must have a certain total free area opening for the return air.
For A/C and HP Air Handlers 1/2 HP Blower Motors Minimum 250 in2 (0.1613 m2) free area opening · Use a Return Grille that can supply sufficient air to ensure proper performance.
For A/C and HP Air Handlers with Electric Heat use a 3/4 HP Blower Motor Minimum 390 in2 (0.2516 m2) free area opening · Use a Return Grille that can supply sufficient air to ensure proper performance.
The return air opening can be on the floor, on a closet front door or a side wall above the air handler casing. If the opening for the return air is in the floor, side walls, or closet door anywhere below the appliance casing, a 6 inches (152.4mm) minimum clearance between the appliance and the wall or door must be provided on the side where the return is located to provide for proper air flow. The 6 inches (152.4mm) minimum clearance is not required if there is a return grille installed above the appliance casing, providing the grille has a sufficient return air opening.

Return air requirements

Closet Wall

Typical Closet Installations Provisions shall be made to permit the air in the rooms and the living spaces to return to the air handler. Failure to comply may cause a reduction in the amount of return air available to the blower, causing reduced air flow and resulting in improper heating and cooling of the living space. The reduced air may cause the air flow handler to cycle on the limit causing premature heating element failure (if electric heat kits are installed).
Upflow Accessory Filter Box Kit An accessory filter box kit can be used on the return air end of the air handler when configured in the upflow position. The filter kit is placed over the return plenum in the floor and sealed to the plenum using sealant or caulking material and/or tape. The air handler is placed on top of the return filter box and the return opening is sealed to prevent leaks.
NOTE · Make sure the flow arrow on the air filter is pointing towards the coil.

Upflow application

In an upflow installation the discharge outlet is at the top. Care should be taken to ensure the unit is level to permit proper condensate drainage. Normal upflow installation will be in a closet or basement. If installed in a closet, it must have a platform framed in. The platform must have an opening centered in the closet that measures at least 12 inches (304.8mm) in height from the floor. A filter frame and filter can be used that covers the opening and is sealed to prevent air from bypassing the filter. A filter grille can be used that is located as described in the RETURN AIR REQUIREMENTS section. The minimum filter size is shown in the table below.

Standard throw away air filter @ 300 ft/min (91.44m/min) or less 800 CFM = 20 x 20 x 1 1000 CFM = 20 x 25 x 1 1200 CFM = 20 x 30 x 1 1400 CFM = 25 x 30 x 1 1600 CFM = 25 x 30 x 1 1800 CFM = 30 x 30 x 1 2000 CFM = 30 x 40 x 1 or two 30 x 20 x 1 2400 CFM = 30 x 40 x 1 or two 30 x 20 x 1

Pleated Air Filter @ 500 ft/min (152.4m/min) or less 800 CFM = 16 x 16 x 1 1000 CFM = 18 x 20 x 1 1200 CFM = 20 x 20 x 1 1400 CFM = 20 x 20 x 1 1600 CFM = 20 x 25 x 1 1800 CFM = 20 x 30 x 1 or two 20 x 15 x 1 2000 CFM = 20 x 30 x 1 or two 20 x 15 x 1 2400 CFM = 25 x 30 x 1 or two 14 x 30 x 1

Another option is to use the Filter Base Accessory Kit. This filter base is placed on the closet floor and secured with screws. The unit is placed on top of the filter base and secured to the base with screws. Use seal strip, tape or calking to seal between the unit and the base.
Connect the supply air outlet to a plenum at the top of the unit and secure it with screws. Use a Non-tape sealant such as mastic or an aerosol sealant to seal duct leakage. If installed in a basement, run supply and return duct work following local codes. Use a Non-tape sealant such as mastic or an aerosol sealant to seal duct leakage.

This air handler uses a Constant Torque high efficiency motor. This motor operates on 240 VAC. The motor speed taps are 24 VAC, 0.03 amps, 60 Hz, and 1 PH. The speed taps can be adjusted according to installation needs. Table 4 shows the motor lead connection labeling and the connection definitions. See blower tables in the later section for airflow data. A total of 24 VAC circuit amps គឺ 0.14 amps.
Change Motor Speeds
1 Turn off all electrical supply circuits to the air handler at the main service (House Circuit Breaker) panel. 2 Remove the blower door and switch the air handler circuit breaker(s) to “OFF”. 3 Disconnect the wire from the isolation relay terminal and reconnect the desired wire to the terminal. The RED wire is high
speed. The VIOLET wire is mid speed. The GREEN wire is low speed. The ORANGE wire is electric heat with high fan speed. The ORANGE wire must be connected to a speed tap that will provide sufficient airflow for the size of the electric heat kit. Refer to the heat kit installation manuals for minimum CFM for electric heat kit activation. 4 Turn the circuit breakers on and reinstall the air handler blower door. 5 Turn on all electrical supply circuits to the air handler at the main service (House Circuit Breaker) panel. 6 When black wire(Standard) is required to be connected to tap 5, the orange wire that originally connected to tap 5 can be connected to any tap except tap 5.

ប្រយ័ត្ន
· To deploy the ETO function, the VSTAT10P-1, an external contact interface module, must be installed in each indoor unit. The ETO is a concept of emergency operation of indoor units. If indoor unit 1 (main indoor unit) stops because of an error, indoor unit 2 (sub indoor unit) starts to operate. Indoor unit 2 operates in the previous mode. [For the first time operation, it starts in 75.2°F (24°C) Auto mode.] To set more detailed operation conditions for the indoor unit 2, use the Lennox Service Software. To use the ETO function, should use Lennox Service Software.

· An external output signal occurs if the R-32 sensor in the indoor unit detects a refrigerant leak, or the sensor has a malfunction or short circuit.
· Based on this signal, safety measures required for the indoor unit, such as ventilation system activation and alarm activation, can be taken.
· VSTAT10P-1 (External Contact Control Module) can be used to link the GAS LEAK output.
