This document provides operating instructions for TCL Windows Type Air Conditioners, specifically models TWAC-15CRA1/K8U(ES) and TWAC-24CRA2/J3U(ES). It covers important safety information, electrical requirements, installation, operation, maintenance, and troubleshooting.
Function Description
The TCL Windows Type Air Conditioner is designed to cool and dehumidify a room, providing a comfortable indoor environment. It features various operating modes including Cool, Dry, Fan, and Auto, allowing users to select the most suitable setting for their needs. The unit can be controlled via an electronic control panel on the unit itself or through a remote control. Additionally, models with Wi-Fi functionality can be controlled remotely using a smartphone application.
Important Safety Instructions
Before installation and use, it is crucial to read and understand all safety messages. The air conditioner must be plugged into a grounded 3-prong outlet, and the ground prong should not be removed. Extension cords or plug adapters should not be used. For servicing, the unit must be unplugged. Moving and installing the air conditioner requires two or more people due to its size and weight.
The manual highlights a "DANGER" warning indicating that failure to follow instructions can cause serious injury or death, and a "WARNING" alert for potential hazards.
Electrical Requirements
The electrical ratings are located on the front left side of the unit. Specific requirements vary by model:
- 15K models: Use a power supply cord with a specific plug type.
- 18K/22K/24K models: Use a different power supply cord plug type.
The air conditioner must be grounded using a 3-prong power supply cord. If a 3-prong outlet is not available, a qualified electrician must install one. The unit is equipped with an LCDI (Leakage Current Detection and Interruption) power cord, which senses leakage current and disconnects power if detected. The LCDI plug has TEST and RESET buttons to verify proper functioning. The RESET button must be engaged for proper use. The power supply cord is a protection device and should not be used as an ON/OFF switch. A damaged power supply cord must be replaced with a new one.

Storm Window Requirements:
If a storm window frame prevents proper tilt for drainage, attach a board or wood piece to the sill, at least 1 1/2" deep and approximately 1/2" higher than the storm window frame.
Prior to Installing:
- Check for airflow obstructions outside (shrubs, trees, awnings) and inside (curtains, drapes, blinds).
- Verify the electrical outlet matches the unit's serial nameplate and is close enough for the power cord.
- Unpack the unit carefully, protecting the floor. Two people should move the unit.
- CAUTION: Be careful to avoid cuts from sharp metal edges and aluminum fins.
Remove Chassis (for window mounting):
- Pull down the front panel and remove the filter.
- Lift the front panel upwards to remove.
- Remove four faceplate screws.
- Gently pull the faceplate away from the cabinet.
- Remove one control panel screw from the front panel.
- Remove screws from the right side of the cabinet.
- Hold the cabinet and pull the base handle to remove the unit. Do not pull or lift near the top of the unit to avoid damage.
Top Angle Rail and Side Bracket Installation:
- Place the air conditioner on a hard, flat surface.
- Attach the foam gasket to the top angle rail.
- Install the top angle side to the cabinet.
Placing the Cabinet Inside the Window:
- Open the window and place the cabinet in the middle of the window sill.
- Ensure the bottom rail is seated over the window sill. Bring the window down temporarily behind the top angle rail.
- Maintain a downward oblique angle (within 3 degrees) for proper drainage.
- Fasten the cabinet to the window sill using two 7/8" Round-Head screws (pre-drill if needed). Add the bottom rail seal over the screws.
- Slide the "I" section of the window panel into the side bracket of the cabinet for both sides.
- Insert top and bottom legs of the window filler panel frame into the channel of the top angle and bottom rail for both sides. Install side retainers to the cabinet.
Install Support Brackets:
- Hold each support bracket flush against the outside of the window sill. Tighten to the bottom of the cabinet. Mark the brackets at the top level of the window sill and remove.
- Assemble sill angle brackets to the support brackets at the marked position. Hand tighten initially.
- Install the support brackets (with sill angle brackets attached) to the bottom of the cabinet.
- Tighten all 6 bolts securely.
Extend the Accordion Panels:
- Raise the window to expose the accordion panel and frame. Loosen locking screws to slide panels easily.
- Extend each panel to fill the window width. Tighten locking screws.
Install the Window Lock and Sash Seal:
- Trim the sash seal to fit the window width. Insert it between the upper and lower sashes.
- Attach the right angle safety lock.
Installing the Chassis into the Cabinet:
- Team lift (two people) the chassis and carefully slide it into the cabinet. Let the front hang out approximately 6".
- CAUTION: Do not push on controls or finned coils.
- Ensure the chassis is firmly seated in the back of the cabinet.
- Insert all removed screws and reattach the front face plate, front panel, and air filter.
Thru-The-Wall Installation:
- NOTE: Consult local building codes and a qualified carpenter.
- Select Wall Location: The air conditioner has a slide-out chassis and can be installed through an outside wall (MAX WALL THICKNESS: 8"). Side louvers must not be blocked.
- The wall surface should not support major structural loads, have plumbing or wiring inside, be near existing electrical outlets, and allow unblocked airflow.
- Prepare the Wall:
- Prepare the wall frame construction. Find the wall stud nearest the center of the installation area.
- Cut a hole on each side of the center stud.
- Measure between the inside edges of every other stud.
- Build a wooden frame with inside dimensions matching the model's specifications. The frame depth should equal the wall thickness. Fill extra space with wood spacers and nail them flush with the drywall.
- If wall thickness is 8-1/2" or more, add aluminum flashing over the bottom of the frame opening.
- Prepare and Install the Cabinet:
- Slide the chassis from the cabinet.
- Place the cabinet into the opening with the bottom rail resting firmly on the bottom board of the wood frame.
- Position the cabinet to tilt properly for water removal.
- Secure the bottom rail to the wood frame with two 1" (2.5 cm) long wood screws.
- Screw or nail the cabinet to the wooden frame (using shims if oversized) to eliminate noise and maintain proper slope.
- Masonry Construction:
- Cut or build a wall opening similar to frame construction.
- Secure the cabinet using masonry nails or anchor screws, or build a frame.
- Ensure masonry above the cabinet is supported. Fasten the cabinet using existing or drilled holes, ensuring side louvers are clear.
- Install exterior cabinet support brackets. Caulk or flash with aluminum if needed for a tight seal.
- Apply wood trim molding around the cabinet sides for aesthetics, without obstructing side louvers.
- Install Chassis: Follow window mounting instructions.
- OPTIONAL: Caulk openings around the cabinet and wood sleeve.

Care and Cleaning
Regular cleaning keeps the air conditioner looking new and minimizes dust buildup.
Air Filter Cleaning:
Check the air filter monthly. Trapped particles and dust can decrease airflow and cause frost on cooling coils.
- Remove the filter by pulling down on the indents of the filter door.
- Wash with liquid dish soap and warm water. Rinse thoroughly.
- Gently shake to remove excess water.
- Let the filter dry completely before reinserting.
- Alternatively, vacuum the filter to remove dust.
Cabinet Cleaning:
- Unplug the air conditioner to prevent shock or fire.
- Dust the cabinet and front panel with an oil-free cloth, or wash with a cloth dampened in warm water and mild liquid soap.
- Rinse thoroughly with a damp cloth and wipe dry.
- Never use harsh cleaners, wax, or polish.
- Wring excess water from the cloth before wiping around controls to prevent damage.
Winter Storage:
For extended storage, remove the unit from the window according to installation instructions and cover it with plastic or place it in its original box.
Wear and Tear:
To minimize wear and tear, always wait at least 3 minutes before changing modes. This prevents compressor overheating and circuit breaker tripping.
