INSTALLATION INSTRUCTIONS

Need help?

Do you have a question about the Daikin KEH067A41E and is the answer not in the manual?

The provided document is an installation manual for a Daikin drain pan heater, models KEH067A41E, KEH063A4E(A), FTDBHMS, and FTDBHML. This device is designed to prevent the drain pan of an outdoor unit from freezing by melting snow that is blown into the product from the outside.

Function Description:

The primary function of the Daikin drain pan heater is to prevent the accumulation of ice in the outdoor unit's drain pan, which can occur due to snow ingress and subsequent freezing. By generating heat, the device melts the snow, allowing the water to drain properly and preventing potential damage or malfunction of the outdoor unit caused by ice buildup. It is particularly recommended for use in heavy snow areas, where it should be installed with a snow-break hood on a high stand.

Important Technical Specifications:

The manual outlines the components included with the drain pan heater, which vary slightly depending on the specific model (KEH067A41E FTDBHMS, KEH063A4E FTDBHML, KEH063A4EA).

Drain Pan Heater (A): One unit is provided for all models.
M4 Piercing Screw (B): 3 screws for KEH067A41E FTDBHMS, and 6 screws for KEH063A4E FTDBHML and KEH063A4EA. These screws are used for fixing the drain pan heater and its harness.
Binding Band (C): One binding band is included for all models, used to secure the drain pan heater harness.
Sealing Material (D): 1 unit for KEH067A41E FTDBHMS, and 2 units for KEH063A4E FTDBHML and KEH063A4EA. This material is used to cover trimmed edges and secure the harness.
Installation Manual (E): One multi-language manual is provided for all models.
Electric Wiring Diagram Label (F): One label for all models, to be affixed to the back of the top plate.
Information Label (G): One label for all models, to be affixed near the manufacturer's label.
Alternate Mounting Plate (H): 0 for KEH067A41E FTDBHMS and KEH063A4E FTDBHML, and 3 for KEH063A4EA. These plates are used for specific models (Type D) to facilitate mounting.

Tools Required for Installation:

Electric Drill
1/8 inch (3.2mm) drill bit
Phillips Screwdriver
Nippers

Usage Features:

The drain pan heater is an accessory that integrates with specific Daikin outdoor unit models. The installation process involves several steps:

Removal of Outdoor Unit Components: This includes removing the top plate, protective wire mesh (for Type B and C models), front plate, and anti-drip cover (for Type B and C models). Labels (electric wiring diagram and information) are affixed during this stage.
Removal of Fan Motor Base: The fan motor base, along with the propeller fan, is removed. It's crucial not to disconnect the fan motor harness and to ensure it doesn't contact the heat exchanger edges.
Installation of Drain Pan Heater:
- For Type D models, pre-mounted mounting plates are exchanged for alternate mounting plates (H).
- Screws are removed from the bottom frame (and left frame for Type D models) to allow insertion of the drain pan heater plates (A) under the heat exchanger.
- The ground plate of the drain pan heater must firmly adhere to the bottom frame (Type A) or partition plate (Type B and C).
- The heater is positioned to avoid contact with the fan motor base.
- If no holes exist, 1/8 inch (3.2mm) holes are drilled in the bottom frame or partition plate, or the included piercing screws are used.
- The drain pan heater is fixed with M4 piercing screws (B).
- Removed screws from the bottom frame (and left frame for Type D models) are reattached.
Routing the Harnesses:
- For Type A Models: A 1/8 inch (3.2mm) hole is drilled in the partition plate if needed. The binding band (C) attached to the drain pan heater harness (A) is fixed with an M4 piercing screw (B). The fan motor base is reinstalled. The drain pan heater harness (A) is placed on top of the fan motor harness and secured with sealing material (D).
- For Type B, C, and D Models: 1/8 inch (3.2mm) holes are drilled in the partition plate (3 locations) if needed. The drain pan heater harness is fixed with M4 piercing screws (B). The fan motor base is reinstalled. The electrical wiring box is trimmed with nippers, and the trimmed edges are covered with sealing material (D). The drain pan heater harness (A) is inserted into the trimmed space and fixed with sealing material (D).
Connecting Terminals: The thermostat-side terminal (black harness) is connected to the leftmost terminal, and the heater-side terminal (white harness) to the second leftmost terminal of the outdoor unit's terminal block. For Type C models, these connect to the last terminal block in use. The drain pan heater harness is bundled and secured with a binding band (C) to eliminate slack.

Maintenance Features:

The manual emphasizes safety during installation and operation. While it doesn't detail ongoing maintenance for the heater itself, it highlights critical safety considerations that indirectly contribute to the device's longevity and safe operation:

Professional Installation: Only trained and licensed personnel should install, adjust, service, or repair the equipment to prevent injury or property damage.
Adherence to Instructions: Installation must strictly follow the manual's instructions and comply with national, state, provincial, and local codes to avoid water leakage, electric shock, or fire.
Use of Specified Parts: Only supplied or specified installation parts should be used to prevent the unit from becoming loose, falling, or causing leaks, electric shock, or fire.
Power Disconnection: Always turn off the power supply before installation or servicing to prevent electric shock.
Proper Wiring: Use specified wires and ensure they are connected and fixed properly to avoid improper force on terminal junctions, which could lead to overheating, electric shock, or fire. Covers must be installed over wires to prevent terminal overheating, electric shock, or fire.
Handling Precautions:
- Wear protective gloves during installation to avoid injury from sharp edges (e.g., suction mouth, aluminum fin, top plate).
- Do not touch the heater unit with bare hands when it's on, as it becomes hot and can cause burns.
- Avoid installing in places with a danger of inflammable gas leakage, as gas buildup can cause fire.
- Prevent small animals from nesting in the outdoor unit, as they can cause malfunction, smoke, or ignition. Users are advised to keep the area clean.
Drilling Caution: When drilling holes, care must be taken not to damage soundproofing material or other components.
Post-Installation Check: After installation, ensure the unit operates properly during startup.
