Frequently Asked Questions - MULTI V PUCKA0 LG

How do I install the LG MULTI V PUCKA0 water pump?

Installation should be performed by a qualified technician. The pump must be mounted horizontally below the condensate drain pan. Connect the inlet to the drain line and the outlet to a suitable drainage point. Ensure the pump is level and the float switch moves freely. Refer to the manual for detailed step-by-step instructions.

What is the maximum lift height of this pump?

The maximum discharge head is 10 meters (32.8 feet). This means the pump can lift water vertically up to 10 meters from the pump level to the discharge point.

How do I clean the pump?

Disconnect power before cleaning. Remove the tank cover and clean the interior with a soft cloth and mild detergent. Rinse with clean water. Do not use abrasive cleaners. Check the float valve for debris. Clean the inlet filter if equipped. Allow to dry completely before reassembly.

Why is my pump not turning on?

Check power supply and ensure the pump is plugged in. Verify that the float switch is not stuck in the down position. Also check for blockages in the inlet or outlet. If thermal overload has tripped, allow the pump to cool down and reset automatically. If issue persists, contact LG support.

Can I use this pump for other liquids besides water?

No, this pump is designed specifically for condensate water from air conditioning systems. Using it with other liquids may damage the pump and void the warranty.

What does the blinking red light mean?

A blinking red light indicates an alarm condition. Common causes include high water level (blocked outlet), pump overheating, or float switch failure. Check the outlet for obstructions and ensure proper ventilation. Refer to the troubleshooting section in the manual.

How often should I replace the pump?

The pump has an expected lifespan of 5-7 years under normal usage. Replace the pump if it shows signs of wear, such as leaks, unusual noise, or frequent alarms. Regular maintenance can extend its life.

Is the pump noisy?

The pump operates at a low noise level of less than 30 dB(A), which is comparable to a whisper. Ensure the pump is mounted on a vibration-absorbing pad to minimize any transmitted noise.

What spare parts are available for this pump?

Available spare parts include the pump head assembly, float switch, check valve, and inlet filter. These can be ordered through LG authorized service centers. Always use genuine LG parts for replacements.

Does the pump have a backup battery?

No, the LG MULTI V PUCKA0 does not include a battery backup. It relies on AC power. If power loss is a concern, consider installing a separate backup power system or a battery-operated emergency pump.

Before Installation

CAUTION

■ Don't install or operate the unit in rooms mentioned below.

① Where mineral oil, like cutting oil is present.
② Where the air contains high levels of salt such as air near the ocean.
③ Where sulphurous gas is present such as that in areas of hot spring.
④ In vehicles or vessels.
⑤ Where voltage fluctuates a lot such as that in factories.
⑥ Where high concentration of vapor spray are present.
⑦ Where machines generating electromagnetic waves are present.
⑧ Where acidic or alkaline vapor is present.
⑨ The option boxes must be installed with entrances downward.
⑩ If you want to install the product outdoors, it should be installed with outdoor casing.

■ Check the mentioned below, when you apply the AHU(Field supply).

① If the AHU (Field supply) provided in the field is exclusively for heating, you must not change the operating mode to cooling on the remote controller. If not, it can cause electric shock, injury or death. If you want to operate in cooling mode, AHU (Field supply) must comply with the following details. (Following)

• The insulation level of AHU (Field supply) motor must be 'F' or above, and the protection level must satisfy 'IP 54'.
• AHU (Field supply) must have the drain pan installed.

② For refrigerant piping of outdoor unit, refer to the installation manual supplied with the outdoor unit.

③ For installation of the wired remote controller(PQRCUSA0/1), refer to the manual supplied with the wired remote controller.

④ For connection of the Dry contact (PQDSBC), refer to the manual supplied with the Dry contact (PQDSBC).

■ AHU Control Kit

① Thermistor cable and remote controller wire should be located at least 50mm away from power supply wires and from wires to the controller. Not following this guideline may result in malfunction due to electrical noise.
② Use only specified wires, and tightly connect wires to the terminals. Keep wiring in neat order so that it does not obstruct other equipment. Incomplete connections could result in overheating, and in worse case electric shock or fire.

Thermistors Installation

Pipe thermistors Installation

Location of the pipe thermistors

A correct installation of the thermistors is required to ensure a good operation :

1. Pipe_In

: Install the thermistor behind the distributor on the coldest pass the heat exchanger (contact your heat exchanger dealer).

1. Pipe_Out

: Install the thermistor at the outlet of the heat exchanger as close as possible to the heat exchanger.

Evaluation must be done to check if the evaporator is protected against freeze-up.

Execute test operation and check for freeze-up.

1 Pipe_In(Suction pipe)
2 Pipe_Out(Discharge pipe)

Pipe thermistors Installation

Installation of the pipe thermistor cable

1. Put the thermistor cable in a separate protective tube.

2. Always add a pull-relief to the thermistor cable to avoid atrain on the thermistor cable and loosening of the thermistor. Strain on the thermistor cable or loosening of the thermistor may result in bad contact and incorrect temperature measurement.

Fixation of the pipe thermistors (Field work)

1. Fix the thermistor with insulating aluminum tape (Field supply) in order to ensure a good heat transference.
2. Put the supplied piece of rubber around the thermistor in order to avoid loosening of the thermistor after some years.
3. Fasten the thermistor with 2 tie wraps.
4. Insulate the thermistor with the supplied insulation sheet.

Pipe thermistors Installation

INSTRUCTION

- Put the thermistor wire slightly top to avoid water accumulation on down of the thermistor.

■ Make good between thermistor and evaporator. Put the top of the thermistors on the evaporator, this is the most sensitive point of the thermistor.

1 Most sensitive point of the thermistor
2 Maximize the contact

Room thermistor

Installation of the Room thermistor

1. The room thermistor have to be installed in the return air part of the AHU(Field supply) mentioned below.

Test Operation

Before test operation, be sure all information is understood completely, and follow the guideline of manual.

■ Check the refrigerant piping of outdoor unit.

(Additional charging of the refrigerant, the maximum allowed piping length and open the stop valve)

* For more detailed information of that, refer to the installation manual supplied with the outdoor unit.

■ Executing the test operation.

1. Connect the power and turn on with the wired remote controller(PQRCUSA0/1).
2. Check the AHU(Field supply) and outdoor unit operation when the wired remote controller (PQRCUSA0/1) is controlled.

Please attach the inform label inside of the door. Please choose proper language defend on your country.
