Section III – Installation

TheVert-I-Pakwas designed for installation in residential and light commercial applications. These instructions detail a typical method of installation. Figure 4 shows the typical component location and airflow paths through the unit.

Units are available in three return air configurations: front "free-return"with disposable filter; front ducted return with 1" duct flange; and left side ducted return with 1" duct flange. See Figure 10 on Page 11.

Figure 4

Unit Configuration

1) INDOOR AND OUTDOOR AIR REQUIREMENTS

The indoor and outdoor air systems are designed to operate at specified airflow rates and external static pressures. The supply and return air duct system pressure losses (including filter, louver/grille and registers) must not exceed the listed external static pressures for either the indoor or outdoor air systems.

CAUTION: Failure to adhere to indoor air and outdoor air requirements as listed in the following sections will void unit warranty.

A.Outdoor Air System

As a completely self-containedsystem, theVert-I-Pakunit requires 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 back side of the unit. The unit may be installed where the outdoor air path runs through the wall of the building directly behind the unit or where the outdoor air intake and discharge paths are ducted separately away from the unit. Figure 9 shows two typical ducted OA designs.

CAUTION: To ensure proper operation, the outdoor air intake and discharge air paths must be free and unobstructed. The two air paths must be situated to ensure that the intake and discharge air do not recirculate (also calledshort-circuit).

C. Indoor-Air(Conditioned Supply Air) System

The VEB/VHB series unit may be applied in either a free return air configuration or a ducted return air configuration. The supply air path is intended to be ducted. The design and construction of the indoor-airsystem must provide adequate air distribution to ensure comfort levels throughout the structure.

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 2).

If the unit is installed in a closet behind a door and the return air louver or grille is directly opposite the unit RA opening, 2- in. clearance is required between the front of the unit and the back side of the louver or grille. If the louver or grille is located elsewhere on the door so it is not directly in front of the RA opening, a minimum of 7-in.clearance is required between the front of the unit and the back side of the door. The minimum "net free open area" required for the RA louver or grille is listed in Table 2.

2) Electrical

DANGER: Electrical shock hazard. Turn OFF electric power at the fuse box or service panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage. Failure to do so can result in property damage, personal injury and/or death.

A. Grounding

CAUTION: The unit must be electrically wired and grounded in accordance with all state and local codes, national electric code, and NFPA 70. Unit and controls will NOT operate unless properly grounded. A ground lug is provided for ground connection. Use only approved copper wire and connectors from unit to service panel.

B. Power Supply

NOTE: Line voltage circuit is completely factory wired. Make all line voltage connections inside circuit breaker junction box.

The circuit breakers or fuses used for branch circuit protection should be UL recognized. If circuit breakers are used, the circuit breaker for the compressor circuit must have a UL HACR rating. If fuses are used, the fuse for the compressor circuit MUST be time delay type.

CAUTION: Units are dual voltage rated208-230/1/60.The 24V control transformer must be connected for either 208V or 240V power source for proper operation. Line voltage must not exceed 253V or go below 197V.The transformer connection must be changed for 208V operation.

Depending on auxiliary heater size, unit must be supplied with 2 or 3 separate 208V or 240V circuits from structure’s fuse box or service panel. Each circuit is internally connected to a circuit breaker located in the unit control box located at the front center of the unit. Refer to Table 4 and Table 5 for required circuits and recommended wire size for each circuit.

3) THERMOSTAT MOUNTING AND WIRING

A. Thermostat Location

Locate the thermostat about 5 ft. above the floor in an area with good circulation at average indoor temperature.

Do not mount the thermostat where it may be affected by:

Drafts or dead-airspots behind doors and in corners.

Hot or cold air flow from ducts.

Radiant heat from sun or appliances.

Concealed pipes or chimneys.

Unheated (uncooled) areas behind thermostat, such as an outside wall.

B. Thermostat Mounting and Wiring

The thermostat is a precision instrument and was carefully adjusted at the factory. Handle it carefully.

CAUTION: Disconnect the power supply before beginning installation of the thermostat to prevent electrical shock or equipment damage. Do not short across the thermostat terminals. This can burn out the thermostat anticipator.

All wiring for the thermostat circuit must comply with NEC, state and local codes. Use No. 20 AWG color-coded,insulated (35°C minimum) wire. If the thermostat is located more than 100 ft. from the unit (as measured along the control voltage wires), use No. 18 AWGcolor-codedwires to avoid excessive voltage drop.

1.In replacement applications, check the existing thermostat wiring for cracked or frayed insulation. Replace any wiring in poor condition. All wiring must comply with local codes and ordinances.

2.Run wiring (if necessary) to the location. Thread the wires through a hole in the packing material saved in Step 2. Connect the wires to the terminals on the back of the thermostat. (See Figure 11.)

3.Push the excess wire back through the hole and plug any opening with packing material to prevent drafts that may affect thermostat performance.

4.Loosely secure the thermostat to the wall with screws through the two mounting holes in the middle of the thermostat.

5.Level the thermostat. Tighten the two mounting screws.

6.Replace the thermostat cover.

C. Wire Thermostat Cable to Unit Terminal Strip

Attach thermostat wires to low-voltageterminal block on left side of control box in locations indicated in Figures 1, 2 & 3.

4)CONDENSATE DRAIN LINE

The condensate drain exits the unit 2" above floor level at the right side front corner of the unit. The condensate drain line is already internally trapped therefore, no external condensate trap is required.

Install a condensate drain line of the same size as the drain fitting on the unit. PVC plastic pipe (3/4 in. I.D.) makes an ideal condensate line (if local codes allow).

Run condensate drain line from unit to floor drain or outside perimeter of building per local codes.

The condensate line must have a minimum drop of 1/4" per running foot as it leaves the unit. When a horizontal run of 15 ft. or longer is required, it may be necessary to install a vent tee in the drain line near the unit or use a larger diameter drain line. This is to eliminate air trapping and allow proper condensate drainage.

Heat pumps generate condensate during both cooling and heating modes. Condensate drain line must be protected from freezing to prevent condensate from backing up in unit during freezing outdoor conditions.

NOTE: If the unit is to be installed in an attic or furred space where damage may result from condensate overflow, it may be necessary to provide afield-suppliedsecondary drain pan. Always refer to local and national codes.

Test Run

Test run in Heating, Cooling, and Emergency Heat 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. Compressor should energize, and warm air should flow from room registers.

d.Set system control to EM HEAT (Emergency Heat). Compressor should turn off and warm air should continue to flow from the registers. (This step is for heat pumps only.)

NOTE: During EM HEAT operation, temperature of air flowing from room registers may be slightly warmer than during normal HEAT mode operation.

Leave both Installation Manual and Users Manual with owner or user of equipment.

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

Section IV – OWNER'S MANUAL AND OPERATING INFORMATION

IDENTIFYING YOUR SYSTEM

Take the time to familiarize yourself with the type of system you have. This knowledge will be of use in understanding the basic operation of your unit.

A self-containedunit, like theVert-I-Pak,has all of its major components in one cabinet located inside your home. The unit does not have a separate outdoor unit like a traditional“split-system”air conditioner or heat pump. Figure 4 shows the location of the major components inside the cabinet.

The product model and rating data label is affixed to the unit front panel and provides the necessary information for specific identification of the unit. You should familiarize yourself with the model and serial numbers listed on the label.

IMPORTANT FACTS

To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts:

Your system should never be operated without a clean air filter properly installed. A dirty, clogged air filter will increase operating costs and shorten the life of the unit. The air filter should be replaced as it becomes dirty.

Supply-airandreturn-airregisters should not be blocked. Restricted airflow reduces the efficiency and life span of your unit.

For your system to function properly, it MUST have a constant supply of outdoor air to the outdoor air coil located inside the unit. The outdoor-airintake and exhaust openings are located on the back side of the unit. Familiarize yourself with the outside air openings on the building and check to ensure that they are not obstructed.

Thermostat

Your multipurpose indoor thermostat is the control center for your comfort system. You should familiarize yourself with its proper operation. Attempting to control the system by other means – for instance, switching the electrical supply power ON and OFF – may cause damage to the unit.

With some thermostats, increasing the HEAT mode temperature set point more than 2°F may cause the auxiliary electric heaters to operate to satisfy the call for heating. To minimize energy costs, do not increase the HEAT mode temperature set point by more than 2°F at a time.

Depending on the design of your home and its ventilation ductwork and registers, areas of warm or cool air may develop throughout the home. Operating the unit with the fan switch “ON” increases air mixing throughout the home and reduces temperature variations within the home.

Dehumidification

During the cooling season, the Vert-I-Pakalso dehumidifies the air in the home while is it cooling the air. After a few minutes of operation, water should run freely from the condensate drain line extended to the outside of your home. If condensate is not running from the drain line, check to be sure that the drain hose or pipe is properly connected to the drain fitting located on the bottom of the unit which is accessible from beneath the home. Check the drain line periodically during the cooling season to ensure the condensate is running freely from outside the home and draining away from the home’s foundation. (Note: in lower humidity climates, the indoor air may be too dry to generate condensate during the cooling mode.)

Heat Pump

If you are a first-timeowner of anall-electricheat pump, the operating characteristics of the system may be different than you are accustomed to as compared to conventional electric resistance, gas or oil furnaces. Air entering a conventional furnace at 60°F may be warmed 60°to 100°F. The supply air leaving the registers would then be between 120°and 160°F depending on the system. A heat pump warms the same 60°F air 20° to 30°F. The supply air leaving the registers would then be between 80° and 90°F. This air may feel cool because it is slightly less than your body temperature. However, it is sufficiently warm to keep you comfortable and is adding heat to your home. A heat pump will run for much longer periods of time than a conventional furnace. This longer operational time is normal for all heat pumps and is saving you energy in comparison to many conventional furnaces. On days with outdoor temperatures below 40°F, it is normal for the heat pump

15

to run for extended periods of time and may be assisted by the auxiliary electric resistance heating elements. Once you understand the operation of your new heat pump, you will appreciate its constant, even heat and lower energy consumption.

Heat Mode Operation

During the heat mode of operation, frost or ice may build up on the outdoor-aircoil after operating for extended periods during particularly cool and humid weather. When this occurs, your heat pump senses this condition and goes through a defrost cycle. During the defrost cycle, theoutdoor-airblower is turned off, and the reversing valve reverses the flow of refrigerant through theoutdoor-aircoil so it is heated and the frost or ice melts. You may notice the defrost cycle inside your home by a faint click and hissing sound and a slight change in the sound created by the blower as the defrost cycle begins and ends. During the defrost cycle, you may also notice that the air is quickly heated as the defrost cycle ends. Outside the home, a cloud of water vapor created by the melting frost or ice may be visible as it is exhausted. This is normal and keeps the unit working efficiently. Do not be alarmed!

Condensate

The heat pump may generate condensate during both the cooling and heating modes of operation. For proper operation, a condensate drain line must be extended from the drain fitting on the right side of the unit to the perimeter of the home or to a proper drain location. The drain line must be sloped towards the outside of the home or drain location and be protected from freezing.

NOTE: In order for condensate to drain freely, the unit must be installed level.

OPERATING THE VERT-I-PAK

THERMOSTAT OPERATION

The operation of the system is controlled by the indoor thermostat. Most thermostats have 3 controls: a temperature control selector, a FAN control, and a SYSTEM or MODE control. (See Figure 3.)

The temperature control is a selector or set of buttons that allows you to establish the degree of temperature that you wish to maintain for your personal comfort. Some thermostats have two temperature control selectors: one for setting the temperature desired during the cooling cycle, and one for setting the heating operation temperature.

Typical settings are 78°F for cooling and 68°F for heating.

Fan Control

The FAN control offers two options for controlling the indoor-airblower: AUTO and ON. When the FAN control is set to AUTO, the blower will operate only while the thermostat operates the cooling or heating equipment. When the FAN control is set to ON, the blower will operate continuously – regardless of whether cooling or heating equipment is operating. This setting allows for continuous air circulation and filtration.

16

System Control

The SYSTEM or MODE control on your thermostat offers the following selections: COOL, OFF, HEAT, and EM HEAT. Neither the cooling nor heating equipment will operate when the SYSTEM or MODE control is set to OFF. With the SYSTEM or MODE control set to COOL, your unit will operate in cooling mode. With the SYSTEM or MODE control set to HEAT, your unit will operate in heating mode.

Auxiliary Heating

Your system also includes an auxiliary electric heating source. The SYSTEM or MODE control options HEAT and EM HEAT provide convenient selection between the two heating appliances. The heat pump will operate when SYSTEM or MODE control is set to HEAT. The auxiliary electric heater may also be used on cold days to supplement heat pump heating. With the SYSTEM or MODE control set to EM HEAT, the heat pump is turned off and the auxiliary electric heat is activated. The unit is now operating as an electric furnace.

On heat pump systems, the wall thermostat regulates the use of auxiliary electric heat to maximize energy efficiency and your home comfort.

COOLING CYCLE

When operating in the cooling cycle, your unit will operate until the indoor temperature is lowered to the level you have selected on the indoor thermostat. On extremely hot days, your unit will operate for longer periods of time and have shorter “off” periods than on moderate days.

The following are typical conditions that add extra heat and/or humidity to your home and force your cooling unit to work longer to keep your home comfortable:

Entrance doors are frequently opened and closed.

Laundry appliances are being operated.

A shower is running.

More than the usual number of people are present in the home.

More than the normal number of electric lights are in use.

Drapes or blinds are open on the sunny side of the building or home.

HEATING CYCLE

With the SYSTEM control of your indoor thermostat set to HEAT, the heating section of your home comfort system will operate until room temperature is raised to the level you have selected. Of course, the heating unit will have to operate for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones. When the demand is greater than the capacity of the heat pump alone, the auxiliary electric heaters will supplement the heat pump.

NOTE: Non-HeatPump models use a single stage heat thermostat. When a demand for heat is made, these units will use the electric heat strip heat immediately.

DEFROST CYCLE

When your heat pump is providing heat to your home and the outdoor temperature drops below 45°F, moisture may begin to freeze on the surface of the outdoor-aircoil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from outside air. To maintainenergy-efficientoperation, your heat pump has an automatic defrost cycle.

The defrost cycle will occur only if ice is sufficient to interfere with normal heating operation. After ice is melted from the outdoorair coil, the unit automatically switches back to normal heating mode.

Do not be alarmed if steam or fog appears at the outdoor-airexhaust during the defrost cycle. Water vapor from the melting ice may condense into a mist in the cold outdoor air.

17

PERFORMING ROUTINE MAINTENANCE

With the proper maintenance and care, your system will operate economically and dependably. Maintenance can be accomplished easily by referring to the following directions. However, before performing any maintenance, consider these important safety precautions:

WARNING: Electrical Shock Hazard. Before attempting any service work or routine maintenance, turn off all electrical connections to the unit. Failure to do so may result in property damage, personal injury and/or death.

CAUTION: Although great care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit.

REPLACE AIR FILTER

A dirty air filter reduces the efficiency of your Vert-I-Pakand allows lint and dirt to accumulate on theindoor-aircoil. Lint and dirt on theindoor-aircoil can damage your unit and void the warranty. The air filter should be replaced as it becomes dirty.

To replace the filter (front air return units):

1.Slide the filter to the right until it clears the filter rails (See Figure 12).

2.Remove the filter.

3.Install new disposable filter.

CAUTION: Do not operate your system without a filter in place, nor block the front of the unit return air opening.

Figure 12 Filter Replacement

Filter Rails

Air Filter

To remove the filter, slide it to the right side of the unit as shown.

Removing the Filter From the Front Filter Rack

18

INSPECT AND CLEAN INDOOR-AIRCOIL

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

INSPECT OUTDOOR-AIRINTAKE AND EXHAUST

The unit’s outdoor-airintake andoutdoor-airexhaust 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, could damage it, and void your warranty.

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.
