Error Code Explanation

Water Drainage

Water Tank Drain

A water tank collects water, enhancing mobility. Tank volumes: 5.5 L/1.45 Gal for CHWA80A/CHWA120A; 9 L/2.38 Gal for CHWA150A/CHWA150PA.

Diagram shows a water tank with Spill-Proof Cover, Water Tank Floater, and Lift Handle.

Full Tank Protection

A built-in floater triggers a sensor when the water tank is full, automatically shutting off the unit to prevent overflow. Ensure the tank is properly reinserted after emptying; otherwise, the floater may remain in the "full" position, and the unit will not resume operation.

Tank Cleaning

Recommended to empty and clean the water tank each time before use.

Cleaning Steps:

1. Use both hands to grasp the tank by its connection points and slide it outward.
2. Lift the tank handle and take it to a sink to pour water out.
3. Put down the handle and place the water tank back into its compartment.

How to Remove the Spill-Proof Cover

1. Align the locking tab with the release slot, wiggle the handle side to side to detach from securing brackets.
2. Loosen two locking tabs on top, then four on the sides of the tank.
3. Grip the cover through the opening and lift straight up.

Gravity Drain Option

Connect the drain port to a drain hose for continuous water outflow using the included gravity drain hose or a standard garden hose (NOT Included).

Diagram shows steps to connect the hose:

1. Locate the drain port on the back. Hold the drain cap and turn counterclockwise to remove.
2. Remove the drain plug from inside the port.
3. Insert the included drain hose into the port and twist counterclockwise to secure.

Diagram shows correct hose placement (downward) and incorrect placement (kinked, upward).

Note:

• If no hose is connected, tighten the drain plug to prevent leakage.
• Hose should run smoothly downward and remain at least 3.94 inches lower than the drain port.
• Twisted, crooked, or blocked hoses can impede water flow and cause condensate to accumulate.

Pump Drain (ONLY for Pump Model: CHWA150PA)

The CHWA150PA model has a built-in pump and pump drain hose for upward or long-distance drainage.

Diagram shows steps to connect the pump drain hose:

1. Locate the pump drain port on the back of the unit.
2. Align the included pump drain hose with the port.
3. Insert the hose all the way into the port until it clicks securely into place.

To disconnect: Do not pull the hose directly. Press the gray release tab on the port connector, then simultaneously pull the hose out.

Important Notes:

• After connecting, verify the pump is activated by checking if the Pump Indicator is illuminated.
• The pump will not drain immediately; it operates when the water tank reaches maximum level and stops when the water is drained to the minimum level.
• In case of power outage, the dehumidifier resumes previous settings, except for the pump. Reactivate the pump manually if needed.

Troubleshooting

If problems persist, disconnect the dehumidifier and contact Waykar Customer Service.

• Competence of service personnel: Information additional to usual procedures is required for appliances with FLAMMABLE REFRIGERANT. Training is carried out by accredited national organizations or manufacturers. Achieved competence must be documented by a certificate.

Information and training:

• Training should cover substance of the following: explosion potential of FLAMMABLE REFRIGERANTS, POTENTIAL IGNITION SOURCES (lighters, switches, vacuum cleaners, heaters), safety concepts (ventilated vs. unventilated enclosures/rooms), and refrigerant detectors.
• Correct working procedures:
  • Commissioning: Ensure sufficient floor area or correct ventilation duct. Connect pipes, perform leak test before charging. Check safety equipment.
  • Maintenance: Portable equipment shall be repaired outside or in a specialized workshop. Ensure sufficient ventilation. Be aware of refrigerant loss/leaks. Discharge capacitors safely. Reassemble sealed enclosures accurately. Check safety equipment.
  • Repair: Similar to maintenance. Be aware of refrigerant loss/leaks. Discharge capacitors safely.
  • Brazing: Procedures include removing refrigerant, purging with nitrogen, leak testing, and reassembling sealed enclosures.
  • Disposal: Ensure ventilation. Remove refrigerant according to regulations. Avoid ignition sources.

No ignition sources: Keep ignition sources (including smoking) far from work areas where refrigerant may be released. Survey area for flammable hazards. Display "No Smoking" signs.

Ventilated area: Ensure the area is open or adequately ventilated before and during work. Ventilation should disperse released refrigerant.

Checks to the refrigerating equipment: Electrical components must be fit for purpose. Follow manufacturer guidelines. For FLAMMABLE REFRIGERANTS, check refrigerant charge vs. room size, ventilation, secondary circuits, markings, and component protection against corrosion.

Checks to electrical devices: Include initial safety checks and component inspection. If a fault compromises safety, disconnect power until resolved. Temporary solutions are acceptable if operation must continue, but must be reported. Initial safety checks include discharging capacitors, ensuring no live components are exposed, and checking earth bonding continuity.

Repairs to sealed components: Disconnect electrical supplies before removing sealed covers. Use permanently operating leak detection if power is necessary. Replace sealed electrical components.

Repair to intrinsically safe components: Do not apply permanent inductive or capacitance loads without ensuring they meet equipment specifications. Replace intrinsically safe components only with manufacturer-specified parts.
