This document is the User's Information Manual for the Amana PHBC/PHDC Heat Pump Package Unit, specifically dated May 1999 (2). It provides essential information for the safe and dependable operation, installation, and maintenance of the unit.
The Amana PHBC/PHDC is a heat pump package unit designed for outdoor installation only. Its primary function is to provide heating and cooling for a building, offering year-round climate control. The unit is designed for safe and dependable service, provided it is properly installed, used, and maintained according to the instructions in this manual. It is crucial to register the unit with Amana to ensure proper communication regarding service or warranty information. The unit's warranty certificate is also supplied and should be kept in a safe place for future reference.
While specific technical specifications like BTU ratings or power consumption are not detailed in this user manual, it emphasizes several operational parameters. The unit is approved for outdoor installation only. It is not designed to provide mechanical cooling at outdoor temperatures below 50°F; if low ambient cooling is required, a qualified servicer should be consulted. The compressor includes protection devices designed to safeguard it against abnormal operating conditions, which do not affect the indoor blower's operation. These devices can cause a delay (up to five minutes) before the compressor starts. The manual also provides a table of recommended maximum indoor relative humidity levels based on outdoor temperatures, ranging from 35% RH at +20°F outdoor temperature to 15% RH at -20°F outdoor temperature. This highlights the unit's role in managing indoor air quality and preventing condensation issues.
The unit's operation is controlled by a room thermostat, which must be of good quality and correctly installed to ensure accurate temperature sensing. The thermostat should be located away from hot or cold drafts or spots on walls. Most thermostats will control both heating and cooling functions and feature a Fan Switch with "Auto" and "ON" settings. In "Auto" mode, the circulating air blower cycles on and off with the heating/cooling demand, while in "ON" mode, it runs constantly. Some thermostats offer automatic switching between heating and cooling, or night setback capabilities to lower temperatures during unoccupied periods. The manual outlines the basic steps for operation: turning on the electrical power, setting the thermostat selector switch to COOL or HEAT (or AUTO if available), and setting the desired temperature. A crucial warning states that the unit should not be used if any part has been under water, and a qualified service technician must be called immediately in such an event. The manual also warns against using the unit as a "construction heater" during building finishing phases, as this can lead to premature failure due to low return air temperatures and exposure to dirty atmospheres.
Routine maintenance is essential for the unit's efficiency and longevity. The manual stresses the importance of never operating the unit without a filter installed, as dust and lint can build up, leading to efficiency loss, equipment damage, and potential fire. While a return air filter is not supplied with the unit, a means of filtering return air must exist, typically located in the return air duct(s). Filter inspection should occur at least every two months, or more frequently depending on local conditions and usage. Dirty throwaway filters must be discarded and replaced, while dirty permanent filters should be washed, thoroughly dried, and sprayed with a filter adhesive before reinstallation. Air flow arrows on the filter must point in the proper direction when installing or reinstalling.
For cleaning the outside coil, it must be inspected annually and cleaned as frequently as necessary to keep finned areas free of lint, hair, and debris. This task, however, is designated for a qualified servicer only, and electrical power must be disconnected before cleaning to prevent electrical shock. The indoor air circulating blower motor and the outdoor coil fan motor are permanently lubricated and do not require additional oiling. Similarly, the compressor motor is hermetically sealed and does not require additional oiling. The manual strongly advises that installation and servicing of this equipment must be performed by qualified, experienced technicians only, emphasizing safety precautions and the potential for personal injury or death if performed by unqualified persons. It also provides a consumer information line (1-800-843-0304) for general questions and information on Amana products, and mentions an extended service plan available through participating dealers for additional parts and labor coverage.
