Indoor Condensate Drain Piping

PIPING INSTALLATION

Observe all local sanitary codes when installing condensate drains.

WARNING

The drain piping should be as short as possible with a constant downward slope. It is recommended to install the condensate drain system with hard polyvinyl chloride (PVC) pipe and matching connectors. Use piping of the same or greater diameter as the unit connection.

The Floor Console drainage port diameter is 1-in (25-mm) OD.

Pitch the condensate drain pipe at a gradual 2.5% pitch (Example: ¼-in drop over a 10-in length) without obstructions. Use pipe hanger/brackets to support the condensate drain pipe from dropping.

If a gradual pitch from the drainage port is not obtainable, use an auxiliary condensate pump with float valve. A float valve is recommended to shut off the system if auxiliary pump fails.

NOTE: Insulate condensate hose and/or pipes to prevent sweating which may cause water stains or wall damage.

Completing Condensate Drainage Piping

• Include the exterior section of condensate hose in the pipe/wire bundle.

• Fasten the refrigerant and condensate pipe assembly to the exterior wall for support.

• The drain pipe should terminate 6 inches above grade.

Test the Condensate Drainage Piping

• Open front panel and remove air filter.

• Slowly add 20 to 24 oz. of water to the drain pan.

• Water must drain freely from the unit If not, check the pipe slope or see if there are any pipe restrictions.

• Verify all piping joints are leak free.

TROUBLESHOOTING

PROBLEM

System does not restart.

ndoor unit emits unpleasant odor

when started

You hear a“water flowing”sound.

A thin fog or vapor coming out of the discharge register when system is running.

You hear a slight cracking sound when the system stops or starts.

The system will not run.

The unit is not heating or cooling adequately.

Water leaking from the indoor unit into the room.

The unit will not deliver air.

CAUSE/SOLUTION

Cause: The system has a built-in three-minute delay to prevent short and/or rapid cycling of

the compressor.

Solution: Wait three minutes for the protection delay to expire.

Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces

or the air filter.

Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist, contact a qualified service professional to clean the coil surfaces.

Cause: It is normal for the system to make“water flowing”or“gurgling”sounds from refrigerant pressures equalizing when the compressor starts and stops

Solution: The noises should discontinue as the refrigerant system equalizes after two or three minutes.

Cause: It is normal for the system to emit a slight fog or water vapor when cooling extremely humid

warm air.

Solution: The fog or water vapor will disappear as the system cools and dehumidifies the room space.

Cause: It is normal for the system to make “slight cracking” sounds from parts expanding and

contracting during system starts and stops.

Solution: The noises will discontinue as temperature equalizes after two or three minutes.

Cause: There are a number of situations that will prevent the system from running.

Solution: Check for the following:

• Circuit breaker is “tripped” or “turned off.”

• Power button of controller is not turned on.

• Controller is in sleep mode or timer mode.

• Otherwise, contact a qualified service professional for assistance.

Cause: There are a number of reasons for inadequate cooling or heating.

Solution: Check the following:

• Remove obstructions blocking airflow into the room.

• Clean dirty or blocked air filter that is restricting airflow into the system.

• Seal around door or windows to prevent air infiltration into the room.

• Relocate or remove heat sources from the room.

Cause: While it is normal for the system to generate condensate water in cooling mode, it is designed to drain this water via a condensate drain system to a safe location.

Solution: If water is leaking into the room, it may indicate one of the following.

• The indoor unit is not level right to left. Level indoor unit.

• The condensate drain pipe is restricted or plugged. All restrictions must be removed to allow continuous drainage by gravity.

• If problem persists, contact a qualified service professional for assistance.

Cause: There are a number of system functions that will prevent air flow.

Solution: Check for the following:

• In heating mode, the indoor fan may not start for three minutes if the room temperature is very low. This is to prevent blowing cold air.

• In heat mode, if the outdoor temperature is low and humidity is high, the system may need to defrost for up to 10 minutes before beginning a heating cycle.

• In dry mode, the indoor fan may stop for up to three minutes during the compressor off delay.

• Otherwise, you should contact a qualified service professional for assistance.
