NOTE: Save the product packaging and installation instructions for future reference. Store the air conditioner in the product box when not in use for an extended period.

How to Install
NOTE: This is necessary for proper condensed water utilization and drainage. If you are not using the Side Panels for any reason, this pitch to the rear muse be maintained!

Remove the air conditioner from the box and place on a hard flat surface, as floor, a bench or a table. There is a Left and Right Window Filler Panel – be sure to use the proper panel for each side. When installed the flange for securing the panel in place to the window sill will be facing into the room.

INSTALLATION & ASSEMBLY INSTRUCTIONS – WINDOW MOUNTING
REMOVE FRONT PANEL AND CHASSIS

1. Pull down the front panel and remove the filter.

2. Lift the front panel upwards to remove and place to the side.

3. Locate the two faceplate screws and remove.
   These screws will need to be re-installed prior to mounting the air conditioner

4. After removing the screws, gently pull away the faceplate from the air conditioner cabinet.

5. Remove the control panel screw and WI-FI module screw (if available) from the front panel.

6. Remove the screws from the cabinet.

7. Hold the cabinet while pulling on the base handle to carefully remove the unit. Do not pull or lift near the top of the unit.

Top Rail Assembly

The top rail must be assembled before installing the air conditioner in the window
Tools Needed: Phillips Screw Driver

1. Place the cabinet on a hard flat surface.
2. Remove top rail from the top form of the packaging material as shown in FIG. A.
3. Align the hole in the top rail with those on the top of the unit as shown in FIG. B.
4. Secure the top rail to the unit with the 3/8” screws as shown in FIG. C.

NOTE: For safety reasons, all 4 screws must be used to attach the top rail.

CAUTION

When handling the unit, be careful to avoid cuts from the sharp metal edges and aluminium fins on the front and rear coils. Be sure that, there will be a 3-lilt angle downward to the unit backside, after finishing the unit installation.

Accordion Panel and Cabinet Assembly

1. Hold the Accordion Panel in one hand and gently pull the centre to free the open end.
2. Slide the free end of the panel into the cabinet as shown. Be sure to leave enough space to slip the top and bottom of the frame into the rails on the cabinet.
3. Once the panel has been installed on the side of the cabinet, make sure it sits securely inside the frame channel by making slight adjustments. Slide the top and bottom ends of the frame into the top and bottom rails of the cabinet. Slide the panel for both sides.
4. Use two or more people, and place the air conditioner into the window opening so the bottom of the air conditioner frame is against the window sill. Tilt the back of the unit slightly download to allow accumulated rainwater to drain out.
5. Fasten cabinet bottom to window sill using two 1/2” screws. Pre-drill holes if needed.

Install Support Brackets

1. Hold each support bracket flush against the outside of the window sill. Tighten each bracket to the bottom of the cabinet as shown. Mark the brackets at top lever of the window sill and then remove.
2. Assemble the sill angle brackets to the support brackets at the marked position with long bolt and locknut as shown. Hand tighten, but not all the way for any changes that may need to be made later during installation.
3. Install the support brackets (with sill angle brackets) to the bottom of the cabinet as shown.
4. Tighten all the bolts with locknuts securely.

Installing the Chassis into the Cabinet

1. Team lift (two people or more) the air conditioner chassis and carefully slide it into the cabinet. Let the front of the air conditioner hang out approximately 6”.
2. CAUTION: DO NOT PUSH ON THE CONTROLS OR FINNED COILS.
3. Be sure the chassis is firmly seated in the back of the cabinet.
4. Insert all screws removed during window installation and fasten, then reattach the front face plate, front panel, and the air filter.
5. If the wall is too near to affect driving the cabinet screw back, you can assemble the chassis lock at the right bottom corner of the chassis with 3/8” screw as shown, before assembling the front panel.
6. Extend the side accordion panels out against the window frame as shown.
7. Drive 1/2” locking screws through frame holes, and drive one 3/4” screw through top rail into the window sash as shown.
8. To secure the lower sash in place, attach right angle sash lock with 3/4” screws as shown.
9. Cut foam seal and insert in the space between the upper and lower sashes as shown.

Storm Window Requirements

A storm window frame will not allow the air conditioner to tilt properly which in turn will keep it from draining properly. To adjust for this, attach a board or piece of wood to the sill. The board or wood piece should have a depth of at least 1/2”. Make sure the board or piece of wood is approximately 1/2” higher than the storm window frame. This will allow the air conditioner to tilt enough for proper drainage.

THROUGH-THE-WALL INSTALLATION INSTRUCTIONS – OPTIONAL

The case may be installed through the wall as optional. Read completely, then follow step-by-step.
NOTE: Obtain all materials locally for mounting the air conditioner through the wall.

IMPORTANT

• Building a wooden frame is required when installing the case through the wall. The opening and dimension of the wooden frame is required as below.

• Through-the-wall installation is not appropriate if any of the side or top louvers of the case is obstructed by the wall.
• All side and top louvres in the case must project on the outdoor side of the wall.
• The room side of the case must project into the room far enough to maximize the balance of the unit.
• The case must be installed level from side to side and with a slight tilt from front to rear. Use a level, no more than a 1/2 bubble will be the correct slant to the outside.
• Lintel angle is required to support bricks or blocks above the opening.
• Flashing is required and should extend the length of the opening to ensure no inside cavity leakage occurs.

NOTE: The allowed maximum wall thickness is less than 8 9/10”. Otherwise, the wall will block the air inlet of the outdoor side, it will effect the normal operation of unit.

1. Build a wooden frame into the wall opening and make sure fasten it securely, which is suitable to the WALL OPENING REQUIREMENT.
2. Remove the air conditioner from the carton box and take off the chassis as window mounting installation.
3. Place the cabinet into the wooden frame, and lock the cabinet by the top rail hole and bottom chassis hole with 1” long wood screws as shown, from inside to outside.
4. Assemble the two Support Brackets with Sill Angle brackets to the cabinet against to the wooden frame as window mounting installation instructions.
5. Assemble the chassis into the cabinet and fasten or lock it, as per window mounting installation instructions.

Important Considerations

• Before installing the appliance, you must read the manual carefully to get the safety information and notes.
• Unit refrigerant charge amount: refer to unit nameplate marking
• A leak test must be done after the installation is completed.
• It is a must to do a safety inspection before maintaining or repairing an air conditioner using combustible refrigerant to ensure that the fire risk is reduced to a minimum.
• It is necessary to operate the machine under a controlled procedure to ensure that any risk arising from the combustible gas or vapour during the operation is reduced to the minimum.

Introduction to Refrigerants R32(Only for R32 Model)

1. Site Safety

4. It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets of the indoor and outdoor units should be not surrounded by obstacles or close to any heat source or combustible and/or explosive environment.
5. If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the refrigerant leaks completely for 15 minutes. If the product is damaged, it is a must to carry such damaged product back to the maintenance station and it is prohibited to weld the refrigerant pipe or conduct other operations on the user’s site.
6. It is necessary to choose the place where the inlet and outlet air of the indoor unit is even.
   It is necessary to avoid the places where there are other electrical products, power switch plugs and sockets, kitchen cabinet, bed, sofa and other valuables right under the lines on two sides of the indoor unit, and also prevent mechanical damage from occurring.
