_, CAUTION: Ifreturn air ducting is not used, an adequately

sized metal return air grille is required. Velocity should not exceed 500 FPM for return air grilles, and 400 FPM for filter grilles. It is recommended that the proper Friedrich return air grille kit be installed in applications where no return duct is

used.

FILTERS

Two replaceable air filters are supplied from the factory. The

filters are accessible through the access panels on the sides of

the unit (See Figure2) or from the inside of the building through the return airgrille.

The combined pressure losses of the return and supply air paths must not exceed the external static capabilities of the system at the design airflow (See Table 1).

The factory-installed filter rails are designed to hold 1" or 2" filters. When using 2" filters the filter rail divider tabs must be

folded flat (See Figure 3).

NOTE: Dirty filters are the most common cause of inadequate heating and cooling performance

• Inspect filters monthly

• Replace disposable type filters before they become clogged

• Use water and mild detergent to clean washable type filters

NOTE: Most filters are marked with an arrow to indicate the proper direction of air flow through the filter The arrow MUST

point in the direction of air flow

OUTDOOR AIR SYSTEM

As a completely self-contained system, OES/OHS series units

require an adequate supply of outdoor air to exchange heat

from the outdoor air coil. The outdoor air intake and discharge

openings are located on the front and sides of the unit.

_IL CAUTION: To ensure proper operation, the outdoor air

intake and discharge air paths must be free and unobstructed for the first 20 inches. The two air paths must be unrestricted to ensure that the intake and discharge air do not recirculate

(also called short-circuit).

CONDENSATE DRAINAGE

A plastic drain hose extends from the drain pan to the vent at the bottom of the unit. This line can be attached to a suitable

drainage system. If this is done, the system must be vented or open type to ensure proper drainage. Condensate water

can freeze in cold weather which could create hazardous situations.

MOUNTING PREPARATIONS

Forming the Duct Flanges

To minimize the possibility of shipping damage, all units are shipped with field formed duct flanges. These flanges must

all be formed into place prior to mounting the unit. The perforated bend lines of the duct flanges provide

a location for field hand bending/forming to occur in a repeatable manner. When forming the flanges, begin at the upper most perforations and work from top to bottom. The procedures for bending the duct flanges are as follows:

• Face the back side ofthe unit,which is the side that will ultimately make contact with the mounting surface. (See Figure 4.)

• Wearing protective gloves, grasp the center of the metal flange with both hands and gradually bend outward at approximately a 45 degree angle.

• Continue this process until the entire length of the

flange is bent to a 45 degree angle.

• Starting back in the center, grasp the flange with both hands and complete the bend to 90 degrees along the entire length. The flange should now be perpendicular to the rear of the cabinet. (See Figure 5.)

• Repeat the above steps for each of the eight perforated metal flanges on the rear of the cabinet.

When completed, there will be eight duct flanges that are perpendicular to the rear of the cabinet. (See Figure 5.)

_, CAUTION: Repeated bending of the flanges from

flat to the perpendicular position will eventually weaken the sheet metal and ultimately cause failure of the metal

flanges.

Installing Sealing Gaskets

In order to ensure a proper air seal between unit and the building, the factory-supplied sealing gaskets must be applied. Failure to install the gaskets may result in air leaks and poor unit performance.

• Facing the mounting side of the unit, retrieve the sealing gaskets from the return air opening of the

unit.

• Next, apply a piece of the gasket vertically to both the left and right side of the air openings as shown.

• With the remaining gasket, seal the top and bottom of both the supply and return air opening as shown.

Gaskets may be cut with a utility knife or torn by hand to the proper length.

MOUNTING THE UNIT

Mounting Information

Two holes must be cut inthe wall for the supply and return air openings. (See Figures 7 and 8)

On wood frame walls, the wall may need to be reinforced in order to hold up to the weight of the unit.

Concrete block walls must be thoroughly inspected to insure that they can handle the unit weight.

It is the installer's responsibility to insure that hardware used

for mountng of unit is correct for wall material.

New Installation

OES/OHS units are affixed to the wall by way of three mounting brackets. The bottom bracket supports the majority of the weight load, and the side brackets hold the unit in place (See Figures 6 and 7).

Friedrich recommends a 1 inch clearance to combustible material for the first 3 feet of duct attached to the outlet air

frame.

1. Locate and mark lag bolt locations and bottom mounting bracket location. (See Figure 8)

2. Mount bottom mounting bracket.

3. Connect the side mounting brackets to the rear corner posts of the unit. Brackets may be mounted with flanges outward or inward. See Figure 6

for dimensions for new installation. Friedrich recommends installing the brackets outward.

4. Connect the rain flashing to the back flange of the unit top by using screws in the top panel. Top rain flashing is shipped secured to the back of the unit. (See Figure 9)

5. Position the unit in the opening and secure to the wall with 5/16 inch lag bolts; use 7/8 inch diameter flat washers on the lag bolts.

6. Secure the rain flashing to the exterior wall and caulk across the entire length of the top. (See Figure 9)

7. On side by side installations, maintain a minimum of 20 inches clearance on both sides to allow

access to heat strips and to allow proper airflow out of the outdoor coil. Additional clearance may be required to meet local or national codes.

Replacement Installation

Friedrich mounting brackets are removable and can be mounted in two ways to ensure the bracket holes are in line

with the studs. (See Figure 6) When doing a replacement project measure the space

between the studs, then look at the chart below, which gives

the space between mounting brackets for all chassis sizes.

Decide in which position the brackets should be mounted to best match the stud spacing. If the unit is to be installed with the brackets facing outwards, (Figure 6) first mount the

brackets onto the unit and then secure to the wall. If the unit

is to be installed with the brackets facing inwards (Figure

6), first mount brackets to the wall, then position the unit up against the wall and secure brackets to the unit.

Economizer (XE)

General Descrption

The economizer provides free cooling when outside conditions are cool and dry enough to satisfy cooling requirements and it is not necessary for the compressor to run. Between 0%

and 100% outside air can be introduced. A built-in exhaust air damper provides pressure relief.

Operation

The economizer will determine if outside air is suitable for

free cooling. If the outside air is suitable for free cooling the

economizer will open and modulate blade position automatically and maintain 55F supply air temperature. Ifthe outside air isnot suitable for free cooling the economizer remains closed and energizes the compressor for cooing operation.

Adjustment (1 ½ - 5 Ton Chassis)

1) (Step 1 & 2 for 1 ½- 3 ton models only) Through the return air opening, remove two (2)screws on the access cover under the blade.* (The minimum position is set from the factory to open the Economizer enough to remove access cover. The Economizer must be energized to allow the blade to open.)

2) Remove the access cover.

3) The enthalpy control is visible through the access opening. Using the chart on page 17,determine the proper enthalpy setting. Adjust the controller to the desired setting using a small flat blade screwdriver. (Factory enthalpy setting is the "D" position.)

III. START UP

SEQUENCE OF OPERATION

COOLING -Any callfor cooling from the thermostat completes the R-Y circuit which activates the compressor contactor, starting both the compressor and outdoor fan motor. The G circuit (indoor fan motor)is automatically completed on any call

for cooling operation. Itcan also beenergized bythe manual fan

switch on the thermostat to provide constant air circulation. HEATING (OHS Models) - Positioning the thermostat system

switch for heat activates the 24-Volt solenoid on the reversing valve. The solenoid terminal "B" is activated constantly from thermostat contact "R" while the switch is in the heating position. A thermostat call for 1st stage heat also completes R-Y, the circuit activating the compressor contactor starting the compressor and blower motor in the same manner that it does in cooling.

DEFROST CYCLE (OHS MODELS ONLY)

The heat pumpcontrol manages temperature and time to control the defrost cycle.

Ambient temperatures below40°F can result incoiltemperatures

below freezing. At these temperatures the coil temperature sensor will signal the heat pump control which starts the

defrost timer. The heat pump control will place the system in defrost mode

after it has received coil temperature reports of 30°F or below

for 30, 60, or 90 minutes.

In Defrost Mode, the reversingvalve switches the unitto normal cooling mode, and the hotgasses melt the ice and frost off ofthe outdoor coil. During this process, the outdoor fan motor stops, and electric strip heaters are activated indoors to maintain the temperature. Once the coil sensor detects 55°F, the heat pump sensor returns the unit to the heating cycle.

Occasionally in high winds and extreme cold, temperatures may create a situation where the sensor does notdetect 55°E In this

situation, the heat pump control will restart heat pump operation in the heating mode after ten minutes.

The heat pump control provides three timer settings (30, 60, and 90 minutes). These settings control the time that the outdoor coil remains below 32°F before the defrost cycle isstarted. Units are shipped at the 60 minute setting for greatest operating economy. If you need to change the setting, remove thewire connected to

the "60" terminal and reconnect it to the desired terminal.

FINAL INSTALLATION CHECKLIST

1. Make sure circuit breakers inside unit are ON.

2. Check to see if all duct work is sealed to unit for an airtight fit.

3. Thermostat is level and properly installed. Heat anticipator indicator is set to the correct setting.

4. Test run in Heating, Cooling, and Emergency Heat

(OHS only) mode as follows:

a. Set fan control to ON. If fan runs, return

control to AUTO setting. This verifies fan is

working properly.

b. Set system control from OFF to COOL. Lower

temperature selector to 50°F or lower. The compressor should energize and cool air should flow from room registers. Once cooling test is complete, return system control to OFF setting. Wait 5 minutes.

c. Set system control to HEAT and raise

temperature selector to 80°F or higher. On OHS models, compressor should energize, and warm air should flow from room registers. On OES models, strip heater will turn on.

d. Set system control to EM HEAT (Emergency

Heat). Compressor should turn off and warm air should continue to flow from registers.

NOTE: On heat pump units in EM HEAT operation, the

compressor is turned off and heat is provided by the electric

heating strips. Therefore, the temperature of the discharge

air may bewarmer or cooler depending on the capacity of the

heat strips used during EM Heat operation.

5. Leave this Installation/Operation Manual with owner or user of equipment.

6. After 72 hours of operation, the unit will achieve full rated operating performance.

I Make sure that ALL panels are properly installed and ALL screws

are returned to the r or g na ocat on and fastened secure y.

IV. SERVICE / WARRANTY

SERVICE HINTS

Caution the end user to maintain clean air filters at all times, and to not needlessly close off supply and return air registers. This reduces air flow throughout the system which shortens equipment service life and increases operating costs.

Alert the end user that switching to the heating cycle when the

ambient temperature is 75°F or higher may trip the automatic reset high pressure switch. The switch will reset automatically once the high pressure situation is eliminated. Check all power

fuses or circuit breakers to ensure theyare ofthe correct rating.

Periodic cleaning of the outdoor coil is essential to permit full and unrestricted air flow circulation.

PRESSURE SERVICE PORTS

High and low pressure service ports are standard on all units so the system operating pressures can be measured.

A technical service data label islocated on the actual unit.
