Maintenance and Cleaning

WARNING

TO AVOID THE RISK OF PROPERTY DAMAGE, ELECTRICAL SHOCK OR PERSONAL INJURY, CLEAN AIR FILTERS AND COILS REGULARLY. CLOGGED OR SEVERLY RESTRICTED FILTERS OR COILS REDUCE AIRFLOW WHICH CAN CAUSE DRASTIC EFFICIENCY LOSS AS WELL AS SEVERE COMPONENT DAMAGE TO COMPRESSORS, ELECTRIC HEATER OR FAN MOTOR. IN EXTREME CASES, CLOGGED FILTERS AND/OR COILS MAY CREATE A FIRE HAZARD AND WILL VOID THE WARRANTY.

WARNING

SOME LOCAL CONDITIONS AND ENVIRONMENTS CAN CAUSE FUNGI AND OTHER MATERIAL TO GROW INSIDE THE PTAC UNIT. THIS MATERIAL WHEN DRIED, AS WELL AS OTHER FOREIGN MATERIAL, SIMILAR TO DRYER LINT IN YOUR CLOTHES DRYER, ARE FIRE HAZARDS. BE SURE TO THOROUGHLY CHECK AND CLEAN THE UNIT'S COILS, BLOWER WHEEL AND BASEPAN PER THE INSTRUCTIONS CONTAINED IN THIS MANUAL.

MONTHLY MAINTENANCE AND CLEANING

Intake Air Filter

To properly maintain the operational performance of your PTAC unit, it is extremely important that the inlet air filter be cleaned once per month or more often if operated in dusty or dirty locations or conditions. The intake air filter is constructed of durable polypropylene. The “air intake” air filter can be easily inserted into the cabinet front using the cabinet filter guides. The intake air grille swings out for easy access to the filter. Before cleaning the intake filter, turn the unit off by setting the mode switch to the OFF position. Filter should be cleaned as required.

The following procedure is used to remove the intake filter:

1.Open the intake grille by grasping the top intake louver.

2.Pull the intake grille open.

3.Slide filter upward and remove.

4.Clean filter with vacuum or with running water.

Reverse this procedure to reinstall the filter.

NOTE: Available accessory filter kits are FK10B (air intake filter - 10 per pack) and CFK10B

(charcoal filter - 10 per pack). The charcoal filters will greatly improve the quality of the air by absorbing odors from tobacco smoke, mold, mildew, etc. Both filters are permanent and cleanable. Contact your sales person for details.

Intake Filter Removal

Vent Screen

Before cleaning the vent screen, disconnect power to the unit by unplugging the power cord at the wall outlet or subbase, or disconnect power at the fuse box or circuit breaker. If unit is operated with vent door closed, the vent screen does not need to be cleaned.

1.Remove the cabinet front as described in Front Removal.

2.Remove the six screws securing the chassis to the wall sleeve.

3.Slide the chassis out of the wall sleeve far enough so that the vent screen is accessible.

4.Remove the three screws securing the vent mesh screen to the partition panel.

5.Clean and replace the vent screen, slide the chassis back into the wall sleeve, secure it in place with six screws and reinstall the front cabinet.

EKTC, EKTH specifications

The Heat Controller EKTH and EKTC models are advanced heating solutions designed to provide energy-efficient climate control for residential and commercial spaces. These heat pumps combine sophisticated technology with user-friendly features to create a comfortable environment regardless of the outside temperature.

One of the standout features of both the EKTH and EKTC units is their inverter technology. This technology allows the compressor to operate at variable speeds, adjusting its output according to the current heating requirements. As a result, these systems provide consistent heating while consuming less energy compared to traditional fixed-speed units. The inverter technology not only enhances efficiency but also minimizes noise levels, making these heat controllers suitable for quiet environments.

Another significant characteristic of the EKTH and EKTC models is their all-weather performance. These heat pumps are engineered to perform effectively in a wide range of temperatures, ensuring reliable heating even in extremely cold conditions. With advanced defrost technology, these units can operate efficiently without freezing, maintaining optimal performance year-round.

User convenience is also a priority with the EKTH and EKTC systems. Both models feature intuitive digital controls that enable users to set their desired temperature comfortably. Additionally, many versions include Wi-Fi connectivity, allowing for remote access and control through a smartphone app. This feature is ideal for individuals seeking to monitor or adjust their heating systems while away from home.

Energy efficiency is a key aspect of the EKTH and EKTC heat controllers. They are designed with high Seasonal Energy Efficiency Ratios (SEER) and Heating Seasonal Performance Factors (HSPF), which indicate their effectiveness in converting energy into heated air. Energy Star certification is often achieved by these models, making them attractive options for energy-conscious consumers looking to reduce their carbon footprint.

With a compact design, the EKTH and EKTC units can be easily integrated into various settings without taking up much space, allowing for flexible installation options. The sleek aesthetic also ensures that they blend seamlessly with interior decor.

In summary, the Heat Controller EKTH and EKTC models represent a cutting-edge solution to heating needs. They combine inverter technology, all-weather performance, user-friendly features, and high energy efficiency to provide reliable and comfortable heating solutions for any environment. Whether for a home or a commercial space, these heat pumps deliver quality and convenience in climate control.
