PTAC Installation Recommendations

For proper PTAC unit performance and maximum operating life please refer to the minimum installation clearances below:

Figure 1

PTAC units should be installed no closer than 12" apart when two units are side by side. If three of more PTAC units are to operate next to one another allow a minimum of 36" between units. Also, a vertical clearance of 60" should be maintained between units installed.

Figure 2

For PTACs on the ground oor or anytime obstructions are present, use the following guidelines:

• For minor obstructions such as lamp poles or small shrubbery a clearance of 12" from the outdoor louver should be maintained.

• For major obstructions such as a solid fence, wall or other heat rejecting device like a condensing unit, a minimum distance of 36" should be kept.

The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for information regarding affects of other installation arrangements. By following these simple recommendations you can be condent that your Friedrich PTAC will provide years of worry free operation.

Section II — Deep Wall Installation (PXWE)

If the wall is thicker than allowed in the notes in Figure 6, a sheet metal wall sleeve extension and ashing MUST be used.

Installation Instructions for the PXWE – 4" Wall Sleeve Extension

The following points MUST be considered when installing a wall sleeve extension:

1 Provision must be made to direct excess condensate from

the back of the wall sleeve into the extension then outside the building or to a drainage system.

2. Air bafes must be mounted to properly direct air ow to and from the condenser.

3. The wall sleeve extension design must allow for the proper mounting of the grille.

4. Caulking is required at all sites where condensate or external water could potentially inltrate into the building.

5. Fabricate and install metal ashing in wall to serve as a drip panel. Refer to drawing for more information.

6. Condensate notches and overow slots must be kept clear of sealant and gaskets so condensate can ow freely into the wall sleeve extension.

NOTE: Improper fabrication or installation of a wall sleeve extension will impair PTAC performance.

Extension Installation

Secure the wall sleeve extension to the wall sleeve before installing it in the wall. Refer to Figure 8 for a guide for fabrication of a condensate drip panel. The panel MUST extend the full depth of the wall sleeve and the wall sleeve extension.

Pay particular care in sealing and caulking the panel where it makes contact with the wall sleeve (see Figure 8). After installation in the wall, secure with fasteners through the sides. Use a good grade of silicone sealant around the sleeve extension. Seal all exposed screw heads. When the installation is complete, the outside grille should be attached to the wall sleeve extension.

920-087-02 (9-03)

E. Heating Control (heat pumps and emergency heat operation)

NOTE: Heat pump models only. Heat pump equipped models use backup electric resistance heating coils. At extremely low, outdoor ambient temperatures, the heat pump is automatically disabled and the unit operates solely on electric resistance heat.

This control is located behind the decorative front cover and is found on the right side panel of the chassis. Its function is to allow you to set the temperature range in which the heat pump operates. This control switches the unit heat operation between heat pump and electric resistance heat based on the outdoor ambient temperature. These change-over temperatures are based on the settings of the control. The factory setting is at the one o'clock position. If you wish to change the factory set point, insert a at-bladed screwdriver into the slot and turn counterclockwise to increase the changeover set point, or clockwise to decrease it.

NOTE: Emergency heat operation only. In the event of a compressor malfunction in the heat pump mode, turn the screw to the extreme counterclockwise emergency heat position. The heater will then cycle using electric resistance heat only. Note that in the emergency heat position, the compressor is locked out, disabling both heat pump and cooling operations. CALL A SERVICE PERSON. DO NOT FORGET TO RETURN THE CONTROL TO ITS ORIGINAL POSITION AFTER REPAIRS ARE MADE OR THE COMPRESSOR WILL NOT COME ON IN COOLING MODE.

NOTE: The factory set point is recommended for optimum performance.

F. Fan Cycle Switch

The fan cycle switch is located behind the decorative front cover below the control panel. It is designed to operate the fan either continuously or intermittently with the compressor or heating elements. When the switch is in the CONTINUOUS position, the fan will run continuously at the selected speed when the unit is turned on. With the fan cycle switch in the CYCLE position, the fan will run only when the compressor or heating elements cycle on.

NOTE: It is recommended that this switch be set in the continuous position for maximum comfort and temperature control.

G. Fresh Air Vent Control

The vent control lever is located behind the front cover on the left side of the unit. The unit is shipped in the closed position with a locking screw in place. The screw must be removed to operate the lever. When the lever is back, (OPEN), outside air is mixed with indoor air. When the lever is forward, (CLOSED), no outside air is admitted into the room and room air is recycled through the unit.

NOTE: The vent should remain closed for peak operating efciency.

920-087-02 (9-03)

H. Air Discharge Grille

Moving parts hazard.

Appendix A: Remote Thermostat Unit Installation

Remote Thermostat Selection & Wiring Guidelines for Packaged Terminal Air Conditioners

Follow the instructions and recommendations of the thermostat manufacturer for installation and wiring. Do not use a conventional heat pump thermostat with emergency electric heat selection for our heat pump units. Our units make an automatic decision about turning on electric heat if the heating demand cannot be met by the heat pump due to low outdoor temperatures.

NOTE: This unit is designed for use with a single stage thermostat only. Improper application of the thermostat may result in property damage, personal injury or death.

Manual Changeover Thermostat

For Heat Pump equipped units: A single stage, heat/cool thermostat with a terminal for a reversing valve operation is required. Terminal "B" should be continuously energized in the heat mode and terminal "G" should be energized whenever there is a call for heating or cooling. Typically, a heat/cool thermostat designed for use with electric heat systems will meet the above requirements.

Remote Thermostat 208V Operation

The simplified connection diagram at left shows the factory congured wiring set for 240V operation. If you are going to use 208V exclusively, switch the two (2) black wires on the 240V post of the primary side of the transformer to the 208V post. This will ensure correct secondary (low) voltages for the unit. This is only required on remote thermostat units.

Auto Changeover Thermostat

A single stage heat/cool thermostat with auto changeover is needed. The wiring scheme is the same as the manual thermostat.

Remote Thermostat Installation

Follow Steps 1 through 5 (pages 12 and 13), then:

6. Locate the terminal strip on the front of the control box (See Figure 9). Attach the thermostat subbase wires (eld supplied) to the appropriately labeled terminals in accordance with the wiring diagram on the side of the chassis.

7. Carefully route the wires alongside the conduit or service cord. Attach the other end of the wires to the appropriate terminals on the thermostat subbase. See the thermostat directions for proper wiring and mounting of the thermostat.

Figure 10

Terminal Strip Location

If the supply voltage is 208V, the low voltage transformer MUST be wired for 208V operation. Failure to do so will result in lower control voltages to the unit and can damage low voltage components.

CAUTION

Remote Thermostat Unit Operation

These units are controlled by the use of a remote thermostat that will cycle the unit to maintain desired room temperature. See thermostat operating instruction sheet for details.

The fan speed switch controls high and low speed fan operation. It is located on the control panel and is independent of the thermostat.

Appendix B: Electrical Wiring for 265 Volt Models

NOTE: It is recommended that the PXSB subbase assembly, the PXCJ conduit kit and the PXDS disconnect switch be installed on all hardwired units. If installing a ush-oor mounted unit, make provisions for all the line voltage power leads and conduit to be removed for ease of maintenance and service to the chassis.

To install the line voltage power leads and conduit to the chassis, follow the instructions below.

1. Remove the four control box retaining screws (A) and open the control box.

2. Pull the chassis power lead wires (B) (located on the bottomright side of the control box) through the plastic bushing so they are located inside the control box.

3. Remove the plastic bushing.

4. Route the line voltage power leads through the hole where the plastic bushing was located, and secure its conduit (use a 1/2" straight conduit connector, with the locknut on the inside of the control box.)

Figure 11

Line Voltage Connections

5. Make the appropriate electrical connections within the control box, then secure the box on the chassis. Detailed instructions are included with the installation instructions for the conduit kit (PXCJ).

6. Route the line voltage power conduit from the control box straight down the right front to the bottom side of the chassis. This will allow the front cover to be installed without interference with the electrical conduit.

2. The indoor coil (evaporator coil), the outdoor coil (condenser coil) and base pan should be inspected periodically (yearly or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper, etc.). Clean the coils and base pan with a soft brush and

components to protect them from water or spray. Allow the unit to dry thoroughly, inspect all gasket material for deterioration (replace as necessary), and then reinstall the chassis in the sleeve.

NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.

Before reinstalling the chassis in the sleeve, inspect the

indoor blower housing, blower wheel, condenser fan blade, and condenser shroud periodically (yearly or bi-yearly) and

4. Inspect the surrounding area (inside and outside) to ensure that the units' clearances have not been compromised or altered.

clean of all debris (lint, dirt, mold, fungus, etc.) Clean the blower housing area and blower wheel with an antibacterial / antifungal cleaner. Use a biodegradable cleaning agent and degreaser on condenser fan and condenser shroud. Use warm or cold water when rinsing these items. Allow all items to dry thoroughly before reinstalling them.

5. Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.

3. Periodically (at least yearly or bi-yearly): inspect all control components, both electrical and mechanical, as well as the power supply. Use proper testing instruments (voltmeter, ohmmeter, ammeter, wattmeter, etc.) to perform electrical

6. Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow them to dry thoroughly before reinstalling them in the chassis.

K. Basic Troubleshooting Techniques

Being familiar with the sequence of operation on Standard Controlled Operating Units or the operation of the Remote Thermostat Controlled Units is important. The following questions and answers may help to identify performance problems.

Environmental Effects - Cooling Mode

Is unit sized to room size area and heat load demand?

Room Width x Length x 3.5 (x-factor) equal a "guesstimate" of the number of BTU's required for the area. The number of people in the room, number of electrical devices, solar gains, etc. are all variable items that can affect proper sizing of the unit. Friedrich recommends that you consult with an applications engineer for proper sizing.

Is the outdoor temperature 60°F or below?

The unit is designed for outdoor temperatures above 60°F.

Is the indoor temperature 80°F or above?

Ambient indoor temperatures of 80°F or above will take a longer period of run time to cool down the area. Long run times may indicate that the unit is undersized.

Is indoor humidity high?

This condition will cause the unit to operate longer to remove humidity before noticing any cooling effect.

Has the heat load been increased by additional devices such as computer equipment, or has the room area been increased where the unit is located?

If conditions have changed, the unit may not be able to cool and condition as effectively as previously planned.

Environmental Effects - Heating Mode

Is unit properly sized to room area and heat load demand?

Multiplying the Width x Length x 3.5 ("x-factor") provides a "guesstimate" of the number of BTU's required for the area. The number of people in the room, number of electrical devices, solar gains, etc. are all variable items that can affect proper sizing of the unit. Friedrich recommends that you consult with an applications engineer for proper sizing.

Is the outdoor temperature 70°F or above? - The unit is designed for outdoor temperatures below 70°F. Is the indoor temperature 60°F or below? Ambient indoor temperatures of 60°F or below will take a longer period of run time to heat the area. Long run times may indicate that the unit is undersized.

Has the room area been increased where the unit is located? If the area where the unit is located has been increased, the unit may not provide adequate heat.

Insufcient Maintenance and Inspection

Installation errors are the most common cause of poor performance. Please follow installation instructions carefully. If other problems exist, see Maintenance and Inspection Troubleshooting Guide below.
