• Where sulfide gas is generated such as a hot spring.  
• Where there is high-frequency equipment.  
10. Install in a location that has a rigid wall or support to minimize the  
sound operation and/or vibration.  
11. Slab or roof mounting - install the unit a minimum of 4 inches above  
the roof or ground surface to avoid ice build-up around the unit.  
Locate the unit above a load bearing wall or area of the roof that  
can adequately support the unit. Consult local codes for rooftop  
applications.  
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.  
12. Install in a location that's far away from combustible materials and  
vapors.  
13. Install in a location that's at least 10 ft away from a TV and radio  
antennas to avoid possible interferences with the operation of the  
air conditioner/heat pump.  
14. Install the unit horizontally.

Solid conductor AWG14 or stranded conductor AWG14 are the MINI-  
MUM allowable wire sizes. There are some applications that will require  
larger gauge conductors depending on the voltage and amperage rat-  
ings 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 con-  
ductors sized using the National Electrical Code (NEC) and the local  
authority having jurisdiction whichever is more stringent. If the equip-  
ment is installed outside of the United States, all local codes within the  
country of origin must be followed.  
DRAIN-WATER HOLE  
BOTTOM FRAME  
DRAIN PLUG  
The Ductless indoor units must have a minimum of 14 gauge, 600  
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).  
DRAIN CONNECTOR  
HOSE (available commerially, inner dia. 0.63”)  
FIGURE 4: Condensate Drainage  
The Ductless outdoor units must have a minimum of 12 gauge, 600  
volt double insulated copper conductors with the exception of the fol-  
lowing models: DHPM30CSM42Q1, DHPM36CSM42Q1, and  
DCPM36CSM42Q1, which require 10 gauge wire. The conductors for  
the outdoor unit should be solid or stranded copper conductors.

USE ANCHORS  
Only use Allen wrenches of sufficient hardness (50Rc - Rockwell  
Harness Scale minimum). Fully insert the wrench into the valve stem  
recess.  
INSTALL ANCHORS  
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.  
FIGURE 9: Masonry Applications  
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.  
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 conden-  
sate drainage.  
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.  
1. Determine the best exit location for utility bundle (line set, conden-  
sate line and wiring).  
5. After completing refrigerant piping, wiring, and drain piping, caulk  
pipe hole gap with putty.  
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.  
OUTSIDE  
INSIDE  
CAULKING  
3. Prior to making the hole and installing wall sleeve for the utility bun-  
dle, 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 plas-  
tic wall anchors. See Figure 13.

WALL PIPE  
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 mount-  
ing screws. See Figure 13.

SECTION XXIII: INDOOR AND OUTDOOR UNITS ERROR CODES  
This section identifies error codes that appear on the front panel of the indoor unit or outdoor unit control. Many of the error codes will automatically  
clear themselves when the error no longer exists. However some error codes may require disconnecting power to the system at the unit disconnect  
switch or circuit breaker in order to clear them and to resume normal system operation.  
* The temperature readout (either  
temperature setpoint or indoor ambient)  
72  
will be replaced by an error code if there  
is a malfunction. If multiple errors are  
detected, the display will alternate  
between each error code.  
NOTE:  
No history is kept on past error codes.
