Adjustment

Loosen the two screws located on the top side of the divider. Slide the top part of the divider toward the outside until the sealing strip makes contact with the outdoor louver. Tighten the divider screws to complete the adjustment.

NOTE:

Let the caulk cure completely before installing the

chassis. This completes the plenum installation.

Condensate Disposal Preparation for 9000 / 12000 / 18000 Models ONLY

IMPORTANT: This step must be performed to ensure that

the chassis installs and seals properly in the wall plenum. If provisions for condensate disposal are made prior to

chassis installation and the drain is to be located beneath the platform for the unit, use the accompanying drawing as a guide for cutout locations. Only one drain per unit is required.

Condensate Disposal System

The Condensate Disposal System increases energy efficiency utilizing a factory installed fan that sling the cold condensate onto the hot outdoor coil.

When high outdoor humidity prevents the slinger from disposing of all the condensate, the excess condensate overflows into the condensate drain pan and out of the ¾” internal drain connections.

NOTE: If the Condensate Disposal System fails to remove all of the condensate from the unit, any excess condensate will overflow from a spillway in the rear of the unit directly into the wall plenum, and drain outside the building. This is your indication that the chassis or drain requires servicing.

Figure 11 Drain Connection

and Location

NOTICE

1) The unit basepan has three (3) provisions (left, right,

and rear) for connecting an external condensate drain.

2) The supplied drain kit must be connected to one of the three (left, right, or rear) ¾” FPT connections on the unit basepan. Use of rear fitting without connection to DWV system (drain, waste, vent) may result in staining of the outside wall.

3) Insert the provided ¾” nipple into the determined connection using field supplied teflon tape or pipe joint compound.

4) With the threaded end of the supplied ¾” union, connect to the nipple with teflon tape or pipe joint compound.

5) Hand-tighten all fittings to prevent damage to unit or fittings.

6) A field supplied drain system must now be installed to the slip end of the union. A trap is recommended and drain connections should be connected to building DWV system.

7) Pitch the drain line on a ¼” downward slope for every foot (1’) of lateral horizontal run to the DWV.

8) The remaining two connections must be plugged using the two ¾” pipe plugs (provided) and field supplied teflon tape or pipe join compound. Hand-tighten to prevent damage to unit or fittings.

9) Do not thread metal or copper pipe fittings directly into unit.

10) Check system for leaks.

11) Failure to follow these procedures may result in serious property damage.

12) A field supplied secondary condensate pan may be required. Check with local codes.

Indoor Return Air Grille Installation

There are two Indoor Return Air Grille options as shown in Figure 12. Choose the option that best suits your needs. Use the installation instructions provided with accessories for installation details.

Figure 12

Return Air Grille Options

NOTE: All Vert-I-Pak chassis are shipped with a 20” x 14” filter installed. If an accessory filter holder is to be used, you MUST remove the factory shipped filter from the chassis. Do NOT use two filters.

Option 1 VPRG4 Return Air Grille

with Access Panel

A field-supplied (25” x 20”) filter is mounted inside the hinged access door. Kit contains hinge bracket for mounting the door with the return air openings high or low on the door for optimal sound attenuation. It is recommended to install the door with the hinge on the right side and the return air openings high on the door.

Option 2 Field Supplied Return Air Grille

Must have a minimum of 250

square inches of free area.

NOTES:

There are the Friedrich recommended return air

grille/filter/access panel arrangements. Consult

Friedrich on other arrangements. Improper return air

arrangements will cause performance problems.

Return air arrangements are shown from the front,

but can also be installed from the right or left side of

the unit.

Ductwork

The supply duct system should be designed via a recognized method such as the equal friction method, or velocity reduction method, using the appropriate duct calculator(s) for the type(s) of duct (i.e. metal duct, duct board, or flex duct) being used in the system. The duct system should be designed for a maximum friction rate of .30" water column taking into consideration all fittings, registers and/or diffusers. DO NOT operate

unit without a supply duct attached.

The return air to Vert-I-Pak "A" series units MUST NOT be ducted, and all units MUST have a free return air configuration to perform properly.

WARNING

CAUTION

Moving parts hazard

Turn off electric power before servicing this component.

Fan can start automatically. Failure to do so can result in property

damage, personal Injury and/or death.

Indoor Air Flow Data

Indoor air flow may be determined by measuring the external static pressure (ESP) of the duct system using an inclined manometer or magnehelic gauge, then consulting chart “A” to determine actual air flow. Rated air flow for each unit is obtained at .10” W.C. when operating with a clean filter and a dry coil (i.e. heating) on the indicated speed at 230 Volts. Use the air flow correction multipliers contained in chart “B” to determine accurate air flow under the listed conditions. Under no circumstances should the Vert-I-Pak equipment be operated at an external static pressure in excess of .30” W.C. Operation of the Vert-I-Pak under these conditions will result in inadequate air flow leading to poor performance and/or premature component failure.

For LOW speed operation, connect the fan output terminal from the thermostat to the GL terminal of the electronic control. For HIGH speed operation, connect the fan output terminal from the thermostat to the GH terminal of the electronic control. For thermostats with two-speed fan capabilities, connect the LOW speed output to the GL terminal, and the HIGH speed output to the GH terminal.

Remote Thermostat and Low Voltage Control Connections

Interface Definition

Remote Thermostat

All Friedrich Vert-I-Pak units are factory configured to be controlled by using a single stage heat/cool remote wall mounted thermostat. The thermostat may be auto or manual changeover as long as the control configuration matches that of the Vert-I-Pak unit.

To connect the wall-mounted thermostat:

1. Pull the disconnect switch.

2. Unscrew and remove the control box panel.

3. After selecting which side you want to run your thermostat wire through, run the wires through the side hole in the box

to reach the connection terminal for the wiring.

4. Make the wire connections, appropriately matching the wires

as shown in the wiring diagram.

5. Once each wire is matched and connected, the unit is now

ready for operation.

6. Reattach the control box cover.

Desk Control Terminals

The Friedrich VERT-I-PAK has built-in provisions for connection to an external switch to control power to the unit. The switch can be a central desk control system or even a normally open door switch.

For desk control operation, connect one side of the switch to the D1 terminal and the other to the D2 terminal (See figure

15). Whenever the switch closes, the unit operation will stop.

NOTE: It is the installer’s responsibility to ensure that all control wiring connections are made in accordance with the installation instructions. Improper connection of the thermostat control wiring and/or tampering with the unit’s internal wiring can void the equipment warranty and may result in property damage, personal injury or death. Other manufacturer’s units and even older Friedrich models may have different control wiring connections. Questions concerning proper connections to the unit should be directed to the factory.

Chassis Final Connections

With the chassis in place, you are now ready to begin chassis connections:

Move the thermostat switches to “OFF” and “AUTO”.

This will keep the thermostat from cycling the chassis until final connections are complete.

Connect the duct work onto the 10” collar. Plastic wire

ties (field supplied) are suggested to secure the duct work in place. Use 2 wire ties, one for each inner and outer flex duct sleeve.

Review the Final Installation Checklist before replacing the power quick disconnect, reconnecting power to the chassis or operating the chassis.

Present the owner or operator of the equipment with the Installation & Operation Manual, all accessory installation instructions, and the name, address and telephone number of the Authorized Friedrich Warranty Service Company in the area for future reference if necessary.

Chassis Operation

Fresh Air Door

The Fresh Air Door is an “intake” system. The fresh air door is opened via a slide on the front of the chassis located just above the indoor coil. Move the slide left to open and right to close the fresh air door. The system is capable of up to 60

CFM of fresh air at .3 H20 internal static pressure.

WARNING

Electrical Shock Hazard

Pull out electrical disconnect on front of the chassis and turn off all power to the unit before servicing.

Failure to do so can result in property damage, personal injury and/or death.

Final Installation Checklist

Inspect and ensure that all components and accessories have been installed properly and that they have not been damaged during the installation process.

Ensure that all installation instructions concerning clearances around the unit have been adhered to.

Check to ensure that the unit air filter, indoor coil, and outdoor coil are free from any obstructions.

Ensure that the circuit breaker(s) or fuse(s) and supply circuit wire size have been sized correctly.

Check the condensate water drain(s) to ensure that they are adequate for the removal of condensate water, and that they meet approval of the end user.

Low Ambient Compressor Cut Out

Each chassis is equipped with low ambient protection in the form of a thermistor, which will prevent compressor operation at low suction temperature.

oom Freeze Protection

This feature will monitor the indoor room conditions and in the event that the room falls below 40ºF the unit will cycle on high fan with the electric heater. This occurs regardless of mode.

Ensure that the entire installation is in compliance with all applicable national and local codes and ordinances having jurisdiction.

Secure all access panels (i.e. front cover and/or control box), apply power to the unit, then start the unit, and check for proper operation in each mode. Instruct the owner or operator regarding the unit’s operation, and the recommended routine maintenance schedule.

NOTE: Maintaining a log for recording the dates of maintenance and/or service is recommended, and should be suggested to the owner or operator of the equipment.

Service & Warranty

Servicing / Chassis Quick Changeouts

The chasis is designed for quick disconnect and change out. For minor electrical service, the control box cover lifts straight up after the screws & disconnect head are removed. For major electrical, refrigeration and fan service the chassis may be removed from utility closet.

To Remove the Chassis from the Closet

A. Switch the wall thermostat off. B. Pull the Power Disconnect located in the fron C. Disconnect the power coming into the unit from the main breaker panel or the closet mounted disconnect. D. Disconnect the electrical connection. E. Disconnect the duct work. F. Slide the chassis out of the wall plenum. G. Lift the chassis out of the utility closet.

WARNING

Electrical Shock Hazard

Pull out electrical disconnect on front of the chassis and turn off all power to unit before servicing.

Failure to do so can result in property damage, personal injury and/or death.

Routine Maintenance

Performing Routine Maintenance

With the proper maintenance and care, your system will operate ecomomically and dependably. Maintenance can be accomplished easily by referring to the following directions. However, before performing any maintenance, see above stated WARNING.

CAUTION

Cut/Sever Hazard

Some edges may be sharp, use gloves or other hand protection when handling unit.

Failure to do so can result in minor to moderate personal injury.

Replace Air Filter

A dirty air filter reduces the efficiency of your Vert-I-Pak and allows lint and dirt to accumulate on the indoor-air coil. Lint and dirt on the indoor-air coil can damage your unit. The air filter should be replaced as it becomes dirty. To replace the filter (chassis mounted return air filter):

1. Slide the filter clear of the filter rails.

2. Remove the filter.

3. Install new disposable filter.

NOTE:

FILTER IN PLACE OR BLOCK THE FRONT OF THE UNIT RETURN AIR OPENING.

DO NOT OPERATE YOUR SYSTEM WITHOUT A

Inspect and Clean Indoor-air Coil

Eventually, minor amounts of lint and dirt may pass through the filter and collect on the indoor-air. These minor accumulations can be carefully vacuumed away with a brush attachment on a vacuum claner. Care must be taken to avoid bending the aluminum finns on the coil. Bent fins should be straightened using a special fin tool avalable from most HVAC supply depots.

spect Outdoor-Ai r (OA) Intake and Exhaust

The unit’s outdoor-air intake and outdoor-air exhaust paths must remain clear. Check the OA exhaust frequently. Keep it free of all debris, snow, or ice. The OA intake should also be kept free of obstructions. Blocking the OA exhaust or OA intake opening will reduce the efficiency of your unit and could damage it.

Inspect and Clean Condensate Drain

The condensate drain must be routed to a suitable drainage area. Check the unit condensate drain periodically. Keep it free of anything that may block or impede the flow of condensate water. If there is any accumulation of foreign matter in the drain pipe, it should be removed and cleaned. The entire drain line must be protected from freezing.

Warranty

All warranty service work must be done by an authorized servicer. See Product Warranty, and consult your dealer or contractor for details.

Electronic Control Error Code Diagnostics and Test Mode
