How Does a PTAC Unit Drain

Bluco Mechanical is an expert in PTAC repair. For information, call  (929) 447-2077.

What is the procedure for draining a PTAC unit? The condensate pan of the PTAC chassis can drain to the sill of the surrounding sleeve by overtopping or a valve in the chassis sill that is activated by low temperature to prevent frost formation on coils.

How are PTAC Units Drained of Their Water?

The water from the indoor coil (evaporator coil) drains from the front of the device to the back through a couple of small slit-like apertures.

What is causing my PTAC to leak? One of the most prevalent causes of evaporator coil dysfunction is dirt buildup. Once a coil is coated in dirt, dust, mold, or other material, the water is no longer linked to its surface as firmly and will drop to the ground. Any filth that is moved through the system would very certainly clog your drains.

Are PTAC units water-based? PTACs are often installed and connected to a building’s hot-water system during construction. The boiler’s hot water feeds into the PTAC, which circulates the generated heat throughout the flat. The PTAC is equipped with a separate chamber that contains coolant and generates cool air.

PTAC Drain Kit Installation

Outdoor drain components must be fitted before installing the wall sleeve condenser grille. Remove the rear enclosure panel and the stiffener for the sleeve. Remove them from the building’s interior. Insert the 1/2″ drain fitting into the opening created by the gasket and plate for the outdoor drain fitting. Utilize two of the outside mounting screws provided to secure this assembly into the holes found on the rear of the wall sleeve. Place the remaining exterior gasket on the outside blank-off plate and use the two provided mounting screws to connect the assembly to the left rear of the wall sleeve. Repair your HVAC ptac units once a year.

Immediately install chassis for a unit. Utilize the provided hardware to attach the condenser grille to the wall sleeve.

PTAC Drain Valve

Changeover of Outdoor Air Temperature

How does the PTAC unit drain? When should you do this? This feature switches the unit’s working mode from heat pump to total resistance heat.

Limits of temperature

The equipment is set to offer temperature limitations for heating and cooling using dip switches on the control panel. The temperature ranges from 50 to 90 degrees Fahrenheit. These temperature limitations assist prevent overheating and overcooling, which saves energy.

Valve for Draining Condensate

The unit includes a condensate drain valve to prevent water from accumulating in the base pan and freezing.

Rapid Recovery of the Heater

The equipment is designed to activate the electric heater immediately upon the Heat Pump cycle commencing. This feature offers the advantage of shortening the time required to attain the desired temperature, resulting in increased comfort.

Defrosting via Reverse Cycle – (PTHP s only)

This feature enables the unit to perform a reverse cycle defrost to avoid the buildup of ice on the outside unit exposed to a cold environment. Ice formation restricts airflow via the coil, lowering the air conditioning unit’s efficiency. The LG PTHP features an active reverse cycle defrost function that melts ice from the outdoor coil, ensuring room comfort and cost savings through the extended operation. When the unit operates at high external temperatures during the cooling cycle, this feature shuts down the compressor to prevent damage.

Remote Control Thermostat

If required, the PTAC air conditioner can be controlled through a four(4) or five(5) wire remote mounted thermostat. The unit incorporates a low voltage power source compatible with any thermostat type – manual, auto changeover, or program. Any unit can also be equipped with a remote thermostat.

How Long Does it Take to Install a PTAC Unit?

Installing a PTAC unit in your house, workplace, or hotel eliminates the need for intricate ducting. However, installation can be difficult. Here’s how to install a PTAC unit without any hassle.

Measure the area

Installing a PTAC unit can be difficult in any place. If you’re replacing an existing unit, measure the old one. If you’re installing a PTAC for the first time, choose a wall location that allows optimal appliance operation. Allow 6-8 inches clearance around the device for adequate air movement.

But it’s not all inside. Ensure the PTAC unit isn’t too close to trees or plants that could restrict ventilation. Remember, wherever you install a PTAC unit, make sure it has the correct Btu output for the space. Even short spurts of cooling won’t dehumidify a room if the conditioner is overloaded.

For new installations, a PTAC unit requires a perfect drywall opening. They are typically 42 inches wide but check the product handbook for exact dimensions.

2. Protect the Setup

An anchored, sturdy installation improves the performance and longevity of PTAC units. Frame the PTAC unit with solid wood studs. Install a lintel over the PTAC unit to protect it from the weight of the wall or window. Also, remember to make sure the device is fully level. Excess water could damage the wall if it’s inclined.

Also, avoid puncturing the base pan while screwing the PTAC unit into a wall sleeve. A leak in the base pan could result in expensive water damage. To maximize energy efficiency and avoid cold breezes, insulate the exterior of a PTAC unit while mounting it.

3. Check the Power Outlets

Unplug the old and plug in the new PTAC device to change the power. For new installations, ensure the electrical outlet and wiring can handle the system’s voltage requirements. Contact a competent electrician to conduct the wiring securely and efficiently. It will save you money in the long run.

4. Seal the PTAC Unit

Enclosures and outside components of the PTAC unit should be tightly sealed to prevent leakage. Check the owner’s manual or manufacturer’s guidelines for additional weather sealing tips. Reading the instructions can save you a lot of headaches in the long run.

5. Check for Errors

It’s always worth double-checking PTAC unit installation.

  • Check the PTAC unit.
  • Check for levelness.
  • Check for damage caused by the installation process.
  • Check that no frames, trim, drapes, furniture, or other obstructions block the vents. A PTAC with restricted airflow is inefficient.

6. Enlist Some Assistance

You may be able to do this entirely on your own. Having experienced PTAC installers assist you can save you time, effort, and even money. Avoid damaging your property or the PTAC unit.

Having a team of professionals on your side can make all the difference when selecting the right PTACs and installing them securely and promptly. Some professionals have experience with one PTAC brand but not another due to brand differences. Find someone who knows how to install the PTAC you have like Bluco Mechanical.
