Maintenance and Cleaning

Cabinet Front

The cabinet front and discharge air grille can be cleaned with a water dampened cloth . Under no circumstances should hydro- carbon-based cleaners (e.g. acetone, benzene, naphtha gaso- line, etc.) be used to clean the front or air grilles. Use care when cleaning the control area.

YEARLY MAINTENANCE AND CLEANING

NOTE: Use a mild biodegradable detergent such as Simple Green™ when cleaning the unit. Special care must be taken to protect the unit’s control board and other electrical components from getting any water on them while cleaning. The use of harsh or caustic cleaning agents or materials such as bleach or coil cleaners that are not designed for PTAC products will cause damage or deterioration of the aluminum fin or coil material and is not recommended. Care must be taken not to bend the aluminum fin stock.

Routine Scheduled Maintenance

To achieve continuing top performance and high efficiency, establish a “once a year” cleaning/inspection schedule for the unit. Take the unit out of the sleeve and thoroughly clean and rinse. Be sure to include in the yearly cleaning the evaporator coils, and condenser coils, basepan, and drain passages. Scheduled maintenance can be accomplished by either local maintenance staff or by an authorized servicer. They must follow the instructions described in this manual.

Adverse Operating Conditions Maintenance

Units operating in dusty or corrosive locations; i.e. dusty con- struction site or sea coast, must be cleaned more often. A minimum of four (4) times a year will maintain proper operational conditions and protect unit components.

Wall Sleeve

Clean the wall sleeve while cleaning the unit. The caulking around the sleeve should be checked to make sure that any potential air and water openings around the sleeve are properly sealed. The wall sleeve’s level should also be rechecked. Proper leveling for most installations are a ¼ bubble tilt to the outside and level from right to left. Contact your sales person for detailed maintenance or cleaning instructions.

Basepan and Condenser Coil

CAUTION

DO NOT USE COMMERCIAL GRADE COIL CLEANERS. SOME OF THESE CLEANERS MAY CONTAIN ETHYLENE DIAMINE TETRACETIC ACID (EDTA) WHICH CAN SHORTEN THE LIFE OF THE CONDENSER COIL.

Before cleaning the basepan and condenser coil, turn OFF unit mode switch and disconnect power to the unit. To disconnect power, either unplug the power cord at the wall outlet or subbase, or disconnect power at the fuse box or circuit breaker.

1.Create a water-tight seal by tightly covering the entire control panel area and fan motor with plastic. Creating this seal pre- vents water from entering the control area or the fan motor and damaging the unit.

2.Spray condenser coil and basepan down with water. Next spray a mild biodegradable detergent such as Simple Green™ onto the condenser coil and basepan. Let set for five (5) minutes.

3.Rinse condenser coil and basepan with water again. NOTE: Ensure water pressure is no higher than that of an ordinary garden hose and the water temperature no higher than 120°F.

4.Tilt the non-compressor side of the unit up no higher than 45 degrees and allow water to drain out the other side of the unit.

5.Remove excess water left in the basepan by wiping the basepan with a dry cloth.

6.Remove the water-tight seal from the motor and control panel area.

7.Reinstall unit back into wall sleeve.

8.Allow unit to dry for 24 hours before reapplying power. When power is reapplied test unit for proper operation.

9.Place a non-acidic algaecide in the basepan to inhibit bacteria growth. Ensure the algaecide is compatible with wet coil op- eration and is not corrosive to the coil.

CAUTION

HIGH PRESSURE AND HIGH TEMPERATURE CLEANING IS NOT RECOMMENDED. DOING SO COULD DAMAGE THE ALUMINUM FIN STOCK AND ELECTRICAL COMPONENTS.

Clearance Check

Clearances around the unit should also be checked to make sure that the intake air and discharge air paths have not become blocked or restricted. A minimum of eight inches clearance is needed from unit to furniture , beds, or other objects for proper operation. Restricted discharge or intake air will reduce the unit’s operational performance. In severe airflow restrictions damage can occur to unit components such as the compressor, electric heater or fan motor.

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.
