Limitations

Install the unit in accordance with all national, state, and

local safety codes, and the following limitations:

• Observe the limitations for the indoor unit, coil, and

appropriate accessories.

• Do not install the outdoor unit with any duct work in

the air stream. The outdoor fan is the propeller type

and is not designed to operate against any additional

external static pressure.

• Observe the maximum and minimum conditions for

operation to ensure a system that gives maximum

performance with minimum service.

Note: See the NOTICE in the Reduced capacity

conditions section.

Reduced capacity conditions

NOTICE

Inverter temperature protection

If excessive inverter temperatures are sensed, the

compressor speed/capacity is reduced until an

acceptable condition is reached. When the inverter

temperature returns to an acceptable level, the system

returns to normal operation.

NOTICE

Overcurrent and undercurrent protection

If a low or high current condition is sensed, the

compressor speed/capacity is reduced until an

acceptable current level is reached. When the system

reaches an acceptable current level, the compressor

and fan return to normal operating conditions.

NOTICE

Overvoltage and undervoltage protection

If a low or high supply voltage condition is sensed

(below 187 VAC or above 265 VAC), the compressor

speed/capacity is automatically reduced until an

acceptable voltage level is reached. When an

acceptable voltage level is sensed, the system

automatically returns to a normal state of operation.

NOTICE

Low ambient protection

Cooling mode: The unit automatically adjusts to

maintain cooling operation in outdoor ambient

conditions down to 35°F (2°C). The unit reduces

capacity and low ambient protection (cooling mode) or

cycles off if asked to provide cooling when the outdoor

temperature is at or below these conditions. Heating

mode: The unit provides compressor heat down to an

outdoor ambient temperature of -5°F (-29°C). As the

outdoor ambient temperature reduces, available heat

reduces for all air source heat pumps.

Piping considerations

When using more than 15 ft of interconnecting tubing,

see Table 2 for charging. For long-line applications,

interconnecting lines over 100 ft must be installed with

liquid line solenoid. Refer to the Piping Application Guide

for more information.

NOTICE

Using a larger than specified line size could result

in oil return problems. Using too small a line results

in loss of capacity and other problems caused by

insufficient refrigerant flow. For the heat pump,

maintain level horizontal refrigerant lines between the

indoor unit and the outdoor unit to facilitate sufficient

oil return.

Add-on replacement/retrofit

When using this unit as a replacement for an existing

R-410A unit, these are matched systems. Replace

the indoor coil and the outdoor unit. Perform the

following steps to ensure correct system operation and

performance.

1. Change out the indoor coil to an approved R-410A

coil/air handling unit combination with the

appropriate metering device.

2. Change out the lineset when replacing an R-22 unit

with an R410A unit to reduce cross-contamination of

oils and refrigerants. If change-out of the lineset is

not practical, take the following precautions:

a. Inspect the lineset for kinks, sharp bends, or

other restrictions, and for corrosion.

b. Determine if there are any low spots that

might be serving as oil traps.

c. Flush the lineset with a commercially available

flush kit to remove as much of the existing oil

and contaminants as possible.

3. If replacing the outdoor unit because of a

compressor burnout, replace the refrigeration lines

or, at a minimum, thoroughly flush the lines with a

commercially available flush kit.

WARNING

Never install a suction-line filter drier in the liquid line

of an R-410A system. Failure to follow this warning

can cause a fire, injury, or death.

Precautions for line installation

Adhere to the following during line installation:

• Connect the outdoor unit to the indoor coil using

field supplied refrigerant grade (ACR) copper tubing

that is internally clean and dry. Units must only be

installed with the tubing sizes for approved system

combinations as specified in the Tabular Data Sheet.

The charge given is applicable for total tubing

lengths up to 15 ft (4.6 m).

• Install the refrigerant lines with as few bends as

possible. Ensure not to damage the couplings or

kink the tubing. Use clean hard drawn copper tubing

where no appreciable amount of bending around

obstruction is necessary. If soft copper must be

used, ensure to avoid sharp bends that may cause a

restriction.

• Install the lines so that they do not obstruct service

access to the coil, indoor section, or filter.

• Isolate the refrigerant lines to minimize noise

transmission from the equipment to the structure.

• Insulate the vapor line with a minimum of 1/2-in.

foam rubber insulation (Armaflex or equivalent).

Insulate liquid lines that may be exposed to direct

sunlight, high temperatures, or excessive humidity.

• Tape and suspend the refrigerant lines correctly. Do

not allow tube metal-to-metal contact. See Figure 2.

Figure 2: Installation of vapor line

• Use PVC piping as a conduit for all underground

installations as shown in Figure 3. Keep buried lines

as short as possible to minimize the build up of liquid

refrigerant in the vapor line during long periods of

shutdown.

Figure 3: Underground installation

Installation Manual: HMH7 Series - 17 SEER Horizontal Discharge Modulating Heat Pump 7

Johnson Controls Ducted Systems

• Pack fiberglass insulation and a sealing material such

as permagum around refrigerant lines where they

penetrate a wall to reduce vibration and retain some

flexibility.

Additional refrigerant charge

The outdoor unit is precharged with enough R-410A

refrigerant for the outdoor unit, the smallest indoor unit,

and 15 ft of lineset. Additional refrigerant per foot of

additional lineset is 0.38 oz for the 24k and 36k models,

and 0.60 oz for the 48k and 60k models (see Table 2).

Refer to the Tabular Data Sheet for more information on

precharge amount and indoor combinations.

CAUTION

When installing the pipe through the wall, secure a cap

at the end of the pipe. Do not place the pipe directly on

the ground.

Unit installation

If installing the unit on a hot sun exposed roof or a

paved ground area that is seasonally hot, raise the unit

sufficiently above the roof or ground to avoid taking the

accumulated layer of hot air into the outdoor unit, which

can cause the unit to derate prematurely.

Transportation and handling

1. Route two lifting slings under the unit as shown

in Figure 4. If there are no packaging materials,

protect the unit with cloth or paper. See Figure 5.

Figure 4: Handling with packaging

Figure 5: Handling without packaging

2. Ensure the unit is balanced and, if safe to do so,

carefully lift the unit up.

Selecting a location for installation

Adhere to the following when selecting a location for

installation:

• Install and anchor the unit on a solid base that is 2 in.

above grade and does not shift or settle, which could

cause strain on the refrigerant lines and possible

leaks. Maintain the clearances shown in Figure 6

and install the unit horizontally in a level position.

The base pad must not come in contact with the

foundation or side of the structure because sound

may transmit to the residence.

• Before starting the installation, select and check the

suitability of the location for the indoor and outdoor

units.

• Ensure that the outdoor unit is installed in an

appropriate location that limits exposure to wind,

rain, snow accumulation, and direct sunlight.

• Locate the outdoor unit away from bedroom

windows or other rooms where sound might be

objectionable.

• Provide ample clearance from shrubs to allow

adequate air to pass across the outdoor coil without

leaves or branches being pulled into the fan.

• Ensure that the outdoor unit has sufficient clearance

for air entrance to the outdoor coil, air discharge,

and service access.

• Keep the length of the refrigerant tubing between

the outdoor unit and the indoor coil as short as

possible to avoid capacity and efficiency losses.

Observe all limitations and clearance requirements.

• Elevate the unit sufficiently to prevent any blockage

of the air entrances by snow in areas where snow

may accumulate. Check the local weather bureau for

the expected snow accumulation in your area.

• Isolate the unit from rain gutters to avoid any

possible wash out of the foundation.

WARNING

The outdoor unit must not be installed in an area

where mud or ice could cause personal injury.

Roof installation

When installing units on a roof, the structure must

be capable of supporting the total weight of the unit,

including a pad, lintels, and rails, which must be used to

minimize the transmission of sound or vibration into the

conditioned space.

Installation Manual: HMH7 Series - 17 SEER Horizontal Discharge Modulating Heat Pump8

Johnson Controls Ducted Systems

Wall mount installation

Ensure to mount the outdoor unit on a solid base that

is sloped to shed water, secure from settlement, and

isolated from the structural foundation or walls to prevent

sound and vibration transmission into the living space.

On occasion, site conditions may require the use of

direct wall mounted brackets to locate and support the

outdoor unit. In these applications, ensure to address unit

base pan support, structural integrity, safe access and

serviceability, as well as the possible sound and vibration

transmission into the structure. Wall mounting requires

three mounting brackets and is best served by a properly

engineered solution. Refer to the Price Pages for the

specific part number for your application.

Avoid the following places for installation where damage

to the outdoor section may occur:

• Where there is machine oil

• Coastal regions where the equipment is prone to

atmospheric corrosion

• Near hot springs where the equipment is prone to

sulfide gas corrosion

• In proximity to high-frequency or wireless

equipment

Figure 6: Minimum clearances when selecting a

location

Note: When operating the outdoor section in low

ambient conditions, follow these instructions:

• Never install the outdoor unit in a place where

its air inlet/outlet side may be exposed directly

to wind.

• To prevent exposure to wind, install the

outdoor unit with its air inlet side facing the

wall.

• To prevent exposure to wind, install a baffle

board on the air outlet side of the outdoor unit.

Installing the drain elbow and drain

hose

About this task:

Condensate water may drain from the outdoor unit when

the unit operates in heating mode. To avoid adverse

conditions in the area around the unit, install the included

drain elbow and a drain hose to drain out the condensate

water. Install the drain elbow and drain the hose before

the indoor and outdoor units are connected.

1. Connect the drain hose (field-supplied, 15 mm

inside diameter) as shown in Figure 7.

Figure 7: Drainage

Note: Do not use a drainage elbow in colder

climates. The drain may freeze and cause the

fan to stop running.

NOTICE

Heat pumps defrost periodically resulting in water

drainage. The unit must not be located where

water drainage may freeze and create a hazardous

condition, such as sidewalks and steps.

Installation Manual: HMH7 Series - 17 SEER Horizontal Discharge Modulating Heat Pump 9

Johnson Controls Ducted Systems

Installing the outdoor unit

1. Use washers when fastening the outdoor section at

the foundation bolts.

2. When fastening the outdoor section with the

foundation bolts, ensure that the anchoring

locations are as shown in Figure 8.

3. Fasten the outdoor section as shown in Figure 9.

4. Make sure to fasten the outdoor unit tightly and in

a horizontal position to prevent noise.

5. Do not drain condensate onto public places as this

may lead to slippery surfaces.

6. Use a strong base, made of concrete or similar, that

positions the outdoor section at least 2 in. from

the ground. This keeps the outdoor section dry

and reduces the chance of corrosion, which could

reduce the life span of the outdoor section. See

Figure 10.
