6 The Vert-I-Pak was 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; f[...]

7 Unit Configuration Figure 4 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 eithe[...]

11 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-air system must provide adequate air distribution to ensure comfort levels throughout the str[...]

12 2) Electrical 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 pane[...]

13 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 ther[...]

15 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-contained unit, like the Vert-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[...]

16 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. Typic[...]

17 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 [...]

18 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 an[...]

19 INSPECT AND CLEAN INDOOR-AIR COIL Eventually, minor amounts of lint and dirt may pass through the filter and collect on the indoor-air coil. 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 usin[...]
