Installation and Maintenance

Safety Notice and Tips

WARNING

• Install the air conditioner on a solid base that can support the unit’s weight. (An inadequate base or incomplete installation may cause injury, due to falling off from the base.)

• Electrical work should be carried out in accordance with the installation manual and the local and national electrical wiring rules or codes.
  (Insufficient capacity or incomplete electrical work may cause electrical shock or fire.)

• Be sure to use a dedicated power circuit. (Never use a power supply shared by another appliance.)

• For wiring, use a cable long enough for the entire distance, and do not use an extension cord.

• Do not put other loads on the power supply, and ensure a dedicated power circuit is used.

• Use the specified types of wires for electrical connections between the indoor and outdoor units. (Firmly clamp the interconnecting wires so that the terminals receive no external stress.)

• Incomplete connections or clamping may cause terminal overheating or fire.

• After establishing connection between all the wires, secure the cables to prevent undue force on the electrical covers or panels. (Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire.)

• There is 100PSIG of high pressure nitrogen in the evaporator, that must be released it first before installation. It indicates that the evaporator is sealed if nitrogen escapes, otherwise, it can indicate an evaporator leak.

• When installing or relocating the system, be sure to keep the refrigerant circuit free from air (Air in the refrigerant circuit may cause an abnormal pressure rise or rupture, resulting in injury or damage.

• If any refrigerant leakage occurs during the installation work, ventilate the room liberally.

• After all installation is completed, ensure that no refrigerant leaks. (The refrigerant can produce toxic gas if exposed to flames.)

• When carrying out piping connections, do not allow air substances other than the specified refrigerant to enter the refrigeration cycle, else it can cause decreased performance, abnormally high pressure in the refrigeration cycle, explosion, and injury.)

• Ensure that the installation has a proper ground-earth connection. Do not ground the unit to a utility pipe, arrester, or telephone grounding. Incomplete grounding may cause electrical shock. (A high surge current from lightning or other sources may cause damage to the air conditioner.)

• An earth leakage circuit breaker may be required depending on the site condition, to prevent electrical shock.

• Disconnect the power supply before wiring, piping, or checking the unit.

Installation of the Indoor Unit

Initial Check

CAUTION

• When moving the unit after unpacking, exercise caution to not exert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts.
• Wear personal protective equipment when installing the unit.

Installation Location
Before selecting the installation site, obtain all required permissions and follow the below parameters:

• Optimal air distribution is ensured.
• The air path is not blocked or obstructed.
• Condensation is able to drain properly.
• Ensure sufficient clearance for future maintenance and servicing.
• Piping between the indoor and outdoor units should be within the allowable limits. (Refer to the installation of the outdoor unit manual)
• The indoor unit, outdoor unit, power supply wiring, and transmission wiring should be kept at least 3 feet away from televisions and radio, which prevents image interference and noise in those electrical appliances.(Noise may be generated depending on the conditions under which the electric wave is generated, even if this distance is maintained.)
• Do not install the indoor unit in a machinery shop or kitchen where vapors from oils or any mists can reach the indoor unit. Any oils will collect on the heat exchanger, thereby reducing the performance of the indoor unit, and may deform, and in the worst case, break the plastic parts of the indoor unit.
• When the unit is installed in a hot and humid place, it is recommended to insulate the cabinet exterior and to use auxiliary drain pans.
• If installed above a finished living space, an auxiliary drain pan(as required by many building codes) must be installed under the entire unit, and its condensate drain line must be routed to a location such that the user will see the condensate discharge.

Installation

NOTE:
These appliances are designed for indoor installation only.
The indoor units can be installed in one of the upright, horizontal left, or horizontal right orientations as shown in the Figures below. Minor field modifications are necessary to convert to horizontal left.

Upflow Installation

Horizontal Right Installation (or hanging from ceiling)

Horizontal Left Installation (or hanging from ceiling)

The upright installation method is selected by default. When the unit is horizontal-right mounted, rotate it to the right by 90 degrees, as shown in the image for horizontal-right installation (2.3b).
When the unit is horizontally left mounted (2.3c), the following steps are required.

1. Disassemble the lower panel and the sealed plate.
2. Disassemble the retaining clips for the evaporator so that the evaporator can be pulled out along the lead rail easily.
3. Rotate the evaporator by 180 degrees and insert it into the upper side of the lead rail.
4. Rotate the unit to the left by 90 degrees, as shown in the image “2.3b: Horizontal-Left Installation”. 5). Reinstall the sealed plate and the lower panel.

Air Duct
Field duct work must comply with the National Fire Protection Association NFPA 90NFPA 90B, and any applicable local ordinances.

WARNING
Do not, under any circumstances, connect return ductwork to any other heat- producing device such as a fireplace insert, stove, etc. Unauthorized use of such devices may result in fire, carbon monoxide poisoning, explosion, personal injury or property damage.

OPTIONAL

Downflow Conversion Instructions

Downflow Installation Steps:

1. When the equipment needs to be installed as downflow, first follow steps 1 ), 2), 3) of “Horizontal left installation” (2.3c) to complete the rotating installation of the evaporator;
2. Remove the grounding wire of the motor, unplug the power cord on the power supply board, and pull it out from the wire hole of the electrical box;
3. Remove the two screws fixing the fan;
4. Pull the fan out of the guide rail and place it on a flat surface for easy operation;
5. Take out the sponge in the accessories bag and paste the sponge to the surface of the fan according to the scheme shown in the right picture;
6. Reinstall the fan back to the device by following the reverse steps of steps 4, 3, and 2 for the inverted installation, connect the grounding wire and power cable correctly, and fix the upper and lower panels;
7. Rotate the equipment by 180 degrees to convert the air outlet to downflow.

Sheet metal ductwork run in unconditioned spaces must be insulated and covered with a vapor barrier. Fibrous ductwork may be used if constructed and installed in accordance with SMACNA Construction Standard on Fibrous Glass Ducts. Ductwork must comply with National Fire Protection Association as tested by U/L Standard 181 for Class l Air Ducts. Check local codes for requirements on ductwork and insulation.
The duct system must be designed within the range of external static pressure the unit is designed to operate against. It is important that the system airflow is adequate. Ensure that the supply and return duct work, grills, special filters, accessories, etc, are accounted for in total resistance calculations.

Refrigerant Pipe

DANGER
Use refrigerant spec. according to the outdoor unit nameplate. When carrying out the leakage check and test, do not mix in any oxygen, acetylene, or any sort of flammable/reactive gas, as these gases may result in explosion. It is recommended to use nitrogen to perform these procedures.

Pipe Material

1. Prepare the copper pipe on-site.
2. Choose dust-free, non-humid, clean copper pipe. Before installing the pipe, use nitrogen or dry air to blow away any dust or impurities on the pipe.
3. Select the copper piping according to outdoor manual.

Piping Connection

1. The connection positions of the pipe are shown in Fig. 4.1.

Fig. 4.1. Connection Positions of the Piping

Refer to the “Outdoor Unit Installation Instructions” for details on piping size selection, piping installation, and charging information.
The coil is shipped filled with Nitrogen. Evacuate the system before charging with refrigerant. Install refrigerant lines so that it does not block service access to the front of the unit.

Nitrogen should flow through the refrigerant lines while brazing.
Use a wet rag or an approved heat paste to protect the TXV sensing bulb during the brazing process.

Drain Piping
The indoor units has a field supplied with primary and secondary 3/4-in. NPT drain connections. When making drain fitting connections to the drain pan, use a thin layer of Teflon paste, silicone, or Teflon tape and install. Hand- tighten afterwards. When making drain-fitting connections to drain pan, do not over-tighten.
All horizontal drain pipes must be pitched downward away from the unit at a minimum of 1/8″ per foot to provide problem-free drainage.

Do not connect the drain pipes directly to sewage pipes, to avoid ammonia odors. The ammonia in the sewage can enter the indoor unit through the drain pipes and corrode the heat exchanger.
Do not twist or bend the drain hose, as excessive force is applied during twisting or bending and may also cause leakage.
The drain line should be insulated where necessary, to prevent sweating and damage due to condensate forming on the outside surface of the pipe.
Test condensate drain pan and drain pipe after installation is complete. Keep the case horizontal (horizontal left or horizontal right) to ensure a smooth drainage, or incline the case 0.5° to the drainage hole, making it the lowest point for draining. Pour water into drain pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no leaks are found in drain pipe fittings, and water is draining from the termination of the primary drain pipe.

NOTES:
If unit is located in or above a living space where damage may result from condensate overflow, a field-supplied, external condensate pan should be installed underneath the entire unit, and a secondary condensate line (with appropriate trap) should be run from the unit into the pan. Any condensate in this external condensate pan should be drained to a designated place. The owner of the structure must be informed that when condensate flows from the secondary drain or external condensate pan, the unit requires servicing, or water damage will occur. Install traps in the condensate lines as close to the coil as possible.

Electrical Wiring

Electrical Installation

CAUTION

• Before proceeding with electrical connections, ensure that power supply is as specified on the unit rating plate. See unit wiring label for proper field high and low-voltage wiring. Make all electrical connections in accordance with the NEC and any local codes or ordinances that may apply. Refer to the NEC(USA) or CSA (Canada) for wire sizing. Use properly-sized copper wire only.
• Every installation must include an NEC(USA) or CSA (Canada) approved over-current protection device.

WARNING
Disconnect all power before servicing or installing this unit.
To avoid electrical shock, fully ensure that the air conditioner is properly grounded.
All routing of electrical wiring must be made through provided electrical knockouts. Do not cut, puncture, or alter the cabinet for electrical wiring.
Knockouts are provided on the indoor unit top panel and sides of the cabinet to allow for entry of the supply voltage conductors. If the knockouts on the cabinet sides are used for electrical conduit, an adapter ring must be used in order to meet UL 1995 safety requirements. An MEC or CEC approved strain relief is to be used at this entry point. Some codes/municipalities require the supply wire to be enclosed in conduit.
Consult your local codes for further details.

Wiring Diagram

If the matching outdoor (condensing) unit does not have an S1 terminal, then ignore the S1 to S1 connection.

NOTE

1. Do not connect dashed line when electric heater is not used.
2. Wiring must be performed according to wiring diagram that is posted on indoor unit.
3. The SI wire between the indoor and outdoor units is not mandatory, especially when the outdoor unit is connected to an indoor unit of a different brand. It is more energy-efficient when the outdoor unit is connected to a Pioneer indoor unit via SI wire. However, it still can run without it.
4. Since the thermostat is locally provided, the terminal block in the diagram may differ from the actual one. The letter Y is the same as Y1.
5. Use standard thermostat wire to make a direct connection between the S1 terminal of the outdoor unit to the indoor S1 connection of the indoor unit. This will add to this system set the ability to digitally communicate between the indoor and outdoor sections to change the indoor unit’s fan speed automatically based on operational heat/cool loads.
