THERMALLY CONDUCTIVE, PATENTED ALUMINUM CORE: The cross-flow heat recovery core transfers heat between the two air streams. It is easily removed for cleaning or service.

MOTORS AND BLOWERS: Each air stream has one centrifugal blower driven by a common PSC motor. 120 VAC, 1.4 Amps.

FILTERS: Washable air filters in exhaust and supply air streams.

MOUNTING THE HRV: Four 10-24 5/8” threaded inserts at corners of case designed to accept four PVC reinforced polyester straps that are sup- plied with the unit.

DEFROST: Damper defrost system; defrosts automatically as the out- door temperature falls.

CASE: Twenty gauge prepainted galvanized steel (G60) for superior corrosion resistance. Insulated to prevent exterior condensation. Drain

connections 2 - 1/2” (12 mm) OD.

WEIGHT: 71 lbs. (32.5 kg) SHIPPING WEIGHT 73 lbs. (33.5 kg)

CONTROLS: Basic ON/OFF control is maintained with the 3 foot, 120VAC, 3-prong electrical cord providing power to the HRV.

HRV DEFAULTS TO LOW SPEED when plugged in. HIGH SPEED op- tion is accessible by connecting remote, low voltage, 2-wire controls (up to 10) or (up to four 28 884 -20 minute fan timers) to designated terminals inside electrical box of HRV.

STANDARD SPEED SETTING can be increased by manipulating jump- ers in electrical box. OFF (Standby) /LOW or OFF/HIGH speed opera- tion also available by manipulating jumpers.

OFF, LOW and HIGH speeds are all remotely controllable when an op- tional 28 883 Dehumidistat Ventilation Control (DVC) is connected to the HRV’s electrical box.

LT-15, LT-20 specifications

The American Aldes LT-20 and LT-15 are two advanced air management solutions designed specifically for residential and light commercial applications. These ventilation fans are engineered to improve indoor air quality, energy efficiency, and comfort in various settings.

One of the standout features of both the LT-20 and LT-15 models is their whisper-quiet operation. These fans are designed with noise reduction in mind, allowing for a comfortable indoor environment without disruptive sounds. The LT-20 operates at a maximum noise level of just 0.3 sones, making it one of the quietest options on the market.

In terms of performance, both models offer different airflow capacities suited to various room sizes. The LT-20 delivers an impressive airflow of up to 200 CFM (Cubic Feet per Minute), making it an ideal choice for larger spaces. Meanwhile, the LT-15 caters to smaller rooms with a maximum airflow of 150 CFM. This flexibility allows homeowners and contractors to choose the best model according to specific ventilation needs.

Energy efficiency is another significant characteristic of the LT-20 and LT-15. Both models are designed with EC motors, which consume less electricity compared to standard motors. This not only lowers operating costs but also contributes to sustainability efforts by reducing energy consumption.

The American Aldes LT series is equipped with advanced control options, including variable speed controls that allow users to adjust airflow based on their requirements. This feature enhances comfort levels by providing the ability to customize ventilation flows in real-time.

The LT-20 and LT-15 models also include integrated filters that capture particulate matter from the air, ensuring cleaner indoor air quality. This is particularly beneficial for individuals with allergies or respiratory conditions, as it helps reduce airborne allergens and pollutants.

Installation is simplified with user-friendly designs and clear instructions, making the process less time-consuming for both professional installers and DIY enthusiasts. The compact design of both models also ensures they fit seamlessly into various spaces without compromising aesthetics.

In conclusion, the American Aldes LT-20 and LT-15 models stand out in the market for their combination of quiet operation, energy efficiency, customizable controls, and air quality-enhancing features. These units provide a practical solution for maintaining healthy indoor environments in homes and light commercial settings alike, making them an excellent investment for anyone looking to improve air management.
