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.

• Use the parts provided or specified parts for the installation work.

• 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.

OUTDOOR UNIT (SEE FIGURE 3 FOR
INSTALLATION DIMENSIONS)

1. Some localities are adopting sound ordinances based on the unit's
sound level registered from the adjacent property, not from the
property where the unit is installed. Install the unit as far as possible
from the property line.

2. When possible, do not install the unit directly outside a window.
Glass has a very high level of sound transmission. For proper
placement of unit in relation to a window see Figure 3.

3. Install unit level or, if on a slope, maintain slope tolerance of 2
degrees (or 2 inches per 5 feet) away from building structure.

4. Install the unit high enough above the ground or roof to allow ade­quate drainage of defrost water and prevent ice or snow build-up
(required for heat pumps).

5. In heavy snow areas, do not locate the unit where drifting will occur.
The unit base should be elevated above the depth of average
snows.

6. When installed in areas where low ambient temperatures exist,
locate unit so winter prevailing winds do not blow directly onto out­door unit.

7. If unit coil cannot be installed away from prevailing winter winds, a
wind barrier should be constructed. Size barrier at least the same
height and width as outdoor unit. Install barrier 12 inches minimum
from the sides of the unit in the direction of prevailing winds as illus­trated in Figure 2.

It is advisable to make a piping loop near outdoor unit so as to
reduce vibration.

For increased efficiency, install the outdoor unit in a location where
continuous direct sunlight or excessive water can be avoided as
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.

must have a minimum of 14 gauge, 600

must have a minimum of 12 gauge, 600

FOR CAPS AND FASTNERS

When servicing or repairing HVAC components, ensure the fasteners
are appropriately tightened. The table below provides torque values for
fasteners.

TABLE 9:

Caps and Fasteners Torque Requirements

Recommended Torque

Parts

English
(ft. - lb.)

Service valve cap 8 ft. - lb. 11
Sheet metal screws 16 ft. - lb. 2
Machine screws #10 27 ft. - lb. 3
Compressor bolts 7 ft. - lb. 10
Gauge port seal cap 8 ft. - lb. 11

Only use Allen wrenches of sufficient hardness (50Rc - Rockwell
Harness Scale minimum). Fully insert the wrench into the valve stem
recess.

Service valve stems are factory-torqued (from 9 ft-lbs for small
valves, to 25 ft-lbs for large valves) to prevent refrigerant loss during
shipping and handling. Using an Allen wrench rated at less than
50Rc risks rounding or breaking off the wrench, or stripping the valve
stem recess.

SECTION X: INDOOR UNIT INSTALLATION

INSTALLING THE WALL MOUNTING BRACKET

Determine that the wall will support the weight of the indoor unit. Refer
to system specifications for indoor unit weight. Install the wall mounting
bracket and make sure it's positioned horizontally and vertically. The
indoor unit must be installed level on the wall to allow proper conden­sate drainage.

1. Determine the best exit location for utility bundle (line set, conden­sate line and wiring).

2. Use the wall mounting bracket as a template to determine the exit
point for utility bundle. Use a carpenter's level or tape measure to
verify the wall mounting bracket is horizontally level and mark the
boring points on the wall. See Figure 11.

3. Prior to making the hole and installing wall sleeve for the utility bun­dle, check to ensure that neither studs nor plumbing are directly
located behind the hole location.

4. Secure the wall mounting bracket to the wall using the provided
screws. If possible, align the rear panel screw holes with wall stud
locations marked on the wall. Make sure you use as many screws
into studs as possible. All other screws must be secured using plas­tic wall anchors. See Figure 13.

5. If the wall is made of brick, concrete or other similar material, then
drill pilot holes in the wall. Insert field-provided anchors for mount­ing screws. See Figure 13.

It is important to use all screws provided to secure the wall mounting
bracket to the wall. Additional holes may be drilled through the metal
wall mounting bracket to better secure wall bracket to wall studs.

WALL HOLE DRILLING

Be sure to caulk the gaps around the pipes with caulking material to
prevent water leakage.

1. Determine the wall hole position.

2. Drill a 2-1/2 inch diameter hole in the wall. The hole should be
slightly downward slant 3/16" to 3/8" (5 to 10 mm) lower than the
indoor side.

3. Measure the thickness of the wall from inside to outside edges and
cut field-provided PVC pipe at a slight angle 1/4" (6mm) shorter
than the thickness of the wall.

4. Place a field-provided plastic cover on the outside end of the PVC
pipe and insert the pipe in the wall hole.

5. After completing refrigerant piping, wiring, and drain piping, caulk
pipe hole gap with putty.

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.

12 Johnson Controls Unitary Products

FIGURE 22: Flaring Tools

6. Check your flaring work and if it's found to be defective, cut off the
defective flare section and redo number 5.

FIGURE 23: Proper and Improper Flaring

LEAK TEST AND EVACUATION

Air and moisture remaining in the refrigerant system will have undesir­able effects as indicated below:

1. Pressure in the system rises.

2. Operating current rises.

3. Cooling or heating efficiency drops.

4. Moisture in the refrigerant circuit may freeze and block capillary
tubing (30 kBtu size only).

5. Water may lead to corrosion of parts in the refrigeration system.

The line set between the indoor and outdoor units must be leak tested
and evacuated to remove any non-condensable and moisture from the
system.

AIR PURGING WITH VACCUM PUMP

Be sure to use a vacuum pump with counter-flow prevention function to
make oil inside the pump does not flow back into the system pipes
when the pump stops.

1. Run the vacuum pump.

2. Connect the charge hose from the manifold valve to the service port
of the gas side packed valve.

3. Connect the charge hose to the port of the vacuum pump.

4. Open fully the low pressure side handle of the gauge manifold
valve.

5. Operate the vacuum pump to begin evacuating.

6. The operation time for evacuation varies with the lineset length and
capacity of the pump. Allow the pumpto operate until the system
has been evacuated downto 300 microns. Allow the pump to con­tinue running foran additional 15 minutes.

7. Turn off the pump and leave the connection secured to the suction/
vapor 2-way service port. After five minutes, if the system fails to
hold 500 microns or less, check all connections for tight fit and
repeat the evacuation procedure.

8. Close the low pressure valve handle of gauge manifold.

9. Open fully the valve stem of the packed valves (both gas and liquid
