Installation manual

Variable Refrigerant Flow System

Panel for Mini 4-Way Cassette Indoor Unit

Model Number:

TVEPANPC4SUSET

 SAFETY WARNING

Only qualified personnel should install and service the equipment. The installation, 

starting up, and servicing of heating, ventilating, and air-conditioning equipment can 

be hazardous and requires specific knowledge and training. Improperly installed, 

adjusted or altered equipment by an unqualified person could result in death or 

serious injury. When working on the equipment, observe all precautions in the 

literature and on the tags, stickers, and labels that are attached to the equipment. 

WARNING

Indicates a potentially hazardous situation which, if not avoided, 

could result in death or serious injury.

CAUTION

s

Indicates a potentially hazardous situation which, if not avoided, 

could result in minor or moderate injury. It could also be used to 

alert against unsafe practices.

NOTICE: 

Indicates a situation that could result in equipment or property-

damage only accidents.

Important: Environmental Concerns! 

Scientific research has shown 

that certain man-made chemicals can affect the earth's naturally occurring 

stratospheric ozone layer when released to the atmosphere. In particular, 

several of the identified chemicals that may affect the ozone layer are 

refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those 

containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all 

refrigerants containing these compounds have the same potential impact 

to the environment. Trane advocates the responsible handling of all 

refrigerants-including industry replacements for CFCs such as HCFCs and 

HFCs.

Important: Responsible Refrigerant Practices!

 Trane believes that 

responsible refrigerant practices are important to the environment, our 

customers, and the air conditioning industry. All technicians who handle 

refrigerants must be certified. The Federal Clean Air Act (Section 608) sets 

forth the requirements for handling, reclaiming, recovering and recycling of 

certain refrigerants and the equipment that is used in these service 

procedures. In addition, some states or municipalities may have additional 

requirements that must also be adhered to for responsible management of 

refrigerants. Know the applicable laws and follow them. 

 

WARNING

Personal Protective Equipment Required!

Installing/servicing this unit could result in exposure to electrical, mechanical and 

chemical hazards. Before installing/servicing this unit, technicians MUST put on all 

Personal Protective Equipment (PPE) recommended for the work being undertaken. 

ALWAYS refer to appropriate MSDS sheets and OSHA guidelines for proper PPE. 

When working with or around hazardous chemicals, ALWAYS refer to the appropriate 

MSDS sheets and OSHA guidelines for information on allowable personal exposure 

levels, proper respiratory protection and handling recommendations. If there is a risk 

of arc or flash, technicians MUST put on all necessary Personal Protective Equipment 

(PPE) in accordance with NFPA70E for arc/flash protection PRIOR to servicing the 

unit. Failure to follow recommendations could result in death or serious injury.

 

WARNING

Proper Field Wiring and Grounding Required!

All field wiring MUST be performed by qualified personnel. Improperly installed and 

grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these 

hazards, you MUST follow requirements for field wiring installation and grounding 

as described in NEC and your local/state electrical codes. Failure to follow code could 

result in death or serious injury. 

Installation

Use the 4 screws (type M5XL35) that are provided with the panel or any M5 

screw that is at least 0.78 in. (20 mm) long and has a flat washer. 

1. Loosen the screws to the cover of the indoor unit electrical component

box.

2. Slide the cover toward the center and down to remove it.

3. Open the grill by locating the two hooks at the top of the grill and pulling 

them forward.

4. Using the hooks on either side of the indoor unit, attach the panel to the 

unit.

5. Detach the panel corners by using the two grooves on each panel corner 

(see circled areas in illustration).

NOTICE

To avoid damage to wiring, handle the corner with the digital display carefully.

6. Install the four screws into the panel.
7. Tighten them evenly to eliminate gaps between panel and ceiling.
8. Replace the corners on the panel.

Note: 

You can adjust the height of three of the corners as shown in the 

illustration, but you cannot adjust the corner with the piping connections.

9. Connect the three panel cables into the proper sockets inside the indoor 

electrical component box. Note the different number of pins on the white 

connectors.

10.Close the electrical component box cover and tighten the screws.

11. Close the grill (attach it first if it has been detached). Ensure that the

hooks on the back of the grill fit properly into the grooves on the panel

(

12.Check the following:

Ensure that the screws have been tightened adequately so that there 

are no leaks between ceiling and panel.

Ensure that the discharge vents are not blocked.

If the angle on the air flow blades was inadvertently changed during 

installation or maintenance, cycle power to the unit to re-align the

blades and restore them to their proper angle.
