SECTION I: GENERAL
These instructions are intended as a general guide and do not supersede local codes in any way. Consult authorities having jurisdiction
before installation.
These units must be installed as a matched system as specified in
the UPG Ductless Technical Guide.
SECTION II: SAFETY
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury
• The unit should be installed by an authorized dealer or contractor according to local codes and in compliance with this manual.
• Follow the instructions detailed in the installation manual.
• Confirm proper insulating, taping and bundling of refrigeration lines, main power lines and drain line (see procedure starting on Page 14).
• Perform electrical work according to the installation manual and local codes. Be sure to use a dedicated circuit (do not connect other electr ical
appliances to the same circuit).
• Ground the unit correctly - do not connect the ground wire to a gas pipe, lightning rod, telephone ground or water pipe. Defective grounding
could cause equipment malfunction and/or electric shock.
• Do not damage the wires.
• Shut off the main power when setting up the indoor P.C. board or wiring.
• Use the specified wires to securely connect the indoor and outdoor units. Attach the wires firmly and avoid applying to much pressure to the terminal block - Stranded wire is highly recommended to connect the outdoor unit to the indoor unit. The stranded wire ensures proper system
communication and operation.
• Do not install the unit in a place where flammable gas may leak.
• Do not use intermediate connection of the power cord or a power extension cord.
• The refrigerant temperature tends to get very high. Make sure you keep the electrical wires away from the copper tube.

• Securely attach the electrical cover to the indoor unit and the service panel to the outdoor unit.
• When installing or relocating the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.
• Do not discharge the refrigerant into the atmosphere. Check that the refrigerant gas does not leak after installation has been completed. If refrigerant leaks during installation, ventilate the room.
• Use appropriate tools and piping materials for installation - the pressure of R410A is 1.6 times higher than R22. Not using the appropriate tools
and materials, or improper installation could cause the pipes to burst causing an injury.
• When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.
• When installing the unit, securely connect the refrigerant pipes before starting the compressor.
• Fasten a flare nut with a torque wrench as specified in this manual.
• Perform the drainage/piping work securely according to the installation manual - If there is defect in the drainage/piping work, water could drip
from the unit, and damage household items.
• Do not install the outdoor unit where small animals may live. Keep the area around the unit clean
• The included remote control could be shipped in various locations in the unit packaging. Locate remote control before discarding packaging (i.e.
bag assembly, styrofoam, etc.). Unit cannot be properly operated without the included remote control.
.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury
CAUTION indicates a potentially hazardous situation, which, if not
avoided may result in minor or moderate injury
alert against unsafe practices and hazards involving only property damage.
Improper or incomplete installation, adjustment, alteration, service or
maintenance could cause personal injury, loss of life, or damage to
property. Installation and service must be performed by a licensed
professional dealer or contractor.
The Clean Air Act of 1990 bans the intentional venting of refrigerant
(CFCs, HCFCs and HFCs) as of July 1, 1992. Approved methods of
recovery, recycling or reclaiming must be followed. Fines and/or
incarceration may be levied for noncompliance.

much as possible.
When operating the air conditioner in low outside temperature, be
sure to follow the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet
side may be exposed directly to wind.
• T o prevent exposure to wind, inst all the out door unit with it s air inlet
side facing the wall and a baffle board on the air outlet side.
Avoid the following places for installation where air conditioner trouble
is liable to occur.
• Where flammable gas could leak.
• Where there is an excessive amount of machine oil in the air.
• Where sulfide gas is generated such as a hot spring.
• Where there is high-frequency equipment.
CONDENSATE DRAINAGE REQUIREMENT (HEAT
PUMP ONLY)
Condensate formed during the heating and defrost processes must be
drained from heat pump units. Drain holes are provided in the base of
the units to ensure proper drainage. Heat pumps must be raised when
installed on a concrete pad or the ground to allow drainage to occur. If
the heat pump unit is installed on a wall mounting bracket, insert the
provided drain connector into one of the 1 inch drain holes and attached
a field-provided insulated drain hose to the connector. Use the provided
rubber plugs to cover any unused drain holes. See Figure 4.

Solid conductor AWG14 or stranded conductor AWG14 are the MINIMUM allowable wire sizes. There are some applications that will require
larger gauge conductors depending on the voltage and amperage ratings on the data plate and the distance that the conductors will be
routed. It is the installing contractor's responsibility to properly size the
electrical conductors for the equipment and for the application.
All of the indoor units and outdoor units should have the electrical conductors sized using the National Electrical Code (NEC) and the local
authority having jurisdiction whichever is more stringent. If the equipment is installed outside of the United States, all local codes within the
country of origin must be followed.
The Ductless indoor units
volt double insulated copper conductors. The conductors for the indoor
unit can be either solid or stranded copper. When possible the indoor
unit should have stranded wire for the communication to ensure proper
communication between the indoor and outdoor unit(s).
The Ductless outdoor units
volt double insulated copper conductors with the exception of the following models: DHPM30CSM42Q1, DHPM36CSM42Q1, and
DCPM36CSM42Q1, which require 10 gauge wire. The conductors for
the outdoor unit should be solid or stranded copper conductors.
The listed wire sizes are only minimum requirements, as previously
stated, the conductors for both indoor and outdoor units must be
sized using the NEC and local authority having jurisdiction.

1. In order to align the drain hose and drain cap, be sure to insert
securely and vertically. Incline insertion will cause water leakage.
2. After removing drain hose, be sure not to forget mounting drain
cap.
3. Be sure to fix the drain hose with tape to the bottom of piping.
4. Prevent drain water from freezing in low temperature environment.
When installing indoor unit’s drain hose outdoors, necessary measure for frost protection should be taken to prevent drain water
freezing.
• Under low temperature environment (when outdoor temperature under 32 °F), after cooling operation is executed, water in
the drain hose could be frozen.
• Once drain water is frozen, the drain hose will be blocked and
water leakage may result from indoor unit.
DRAIN PIPING
• If the extension drain hose has to pass through a room, make
sure it's wrapped with commercially sold insulation.
• The drain hose should point downward for easy drain flow.
• If the drain hose provided with the indoor unit is too short, make
sure you connect it with a field-provided drain hose.
• When connecting the drain hose to the hard vinyl chloride pipe,
make sure it's inserted securely into the pipe.
DRAIN HOSE JUNCTION
• If drain hose extension or embedded drain piping is required, use
appropriate parts that match the hose front end. See Figure 18.
• Insert drain hose into the handle of drain pan, and join drain hose
and connecting hose according to Figure 18.
• Attach the Insulation (Drain hose) to the drain hose. See Figure
19.
SECTION XIII: FLARING WORK AND
PIPING CONNECTIONS
FLARING WORK
Main cause for refrigerant leakage is due to defect in the flaring work.
Carry out correct flaring work using the following procedure.
1. Measure the distance between the indoor and outdoor units.
2. Cut the copper pipe about 6 to 8 inches (15 to 20 cm) longer than
the measured distance with a pipe cutter.
FIGURE 20: Pipe Cutting Approved Method
3. Use a pipe reamer or file to completely remove all burrs from the
cut cross section of the pipe.
a. Put the end of the copper pipe in a downward direction to avoid
having burrs drop in the piping.
FIGURE 21: Deburring Line Set
4. Remove flare nuts attached to indoor and outdoor units then put
them on pipes that have completed burrs removal (not possible to
put them on after flaring work).
5. Use a flaring tool to perform flaring work at the end of the copper
pipe. Use the table below as a guideline when performing flaring
work.
FIGURE 18: Drain Hose Extension
FIGURE 19: Drain Hose Insulation
Insert the drain hose and drain cap into the drain port, making sure
that it comes in contact with the back of the drain port, and then
mount it. If the drain hose is not connected properly, leaking will
occur.

This system contains both refrigerant and oil. Some rubber roofing
material may absorb oil. This will cause the rubber to swell when it
comes into contact with oil. The rubber will then bubble and could
cause leaks. Protect the roof surface to avoid exposure to refrigerant
and oil during service and installation. Failure to follow this notice
could result in damage to roof surface.
SECURING OUTDOOR UNIT TO SLAB OR FRAME
If the outdoor unit is installed on a field-provided slab or frame, use lag
bolts or equivalent to secure the outdoor unit to the slab or frame.
