OPERATION Electronic Control Board Features The Friedrich Vert-I-Pak has state of the art features to improve guest comfort and conserve energy. Below is a list of standard features on every Friedrich VPAK and their benefit to the owner. Quite Start/ Stop Fan Delay The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing or stopping immediately. Upon call for cooling or heating the unit fan will run for five seconds prior to en-ergizing the compressor.
Operation Electronic Sequence of Operation Note: Unit is operated by a wired remote wall t-stat which is connected to an electronic control board at the VPAK unit. Compressor and Reversing Valve Control Active Mode Compressor Reversing Valve Cooling On De-Energized Heat - Pump On Energized Heat - Electric Off Fan Only Off Figure 341 (Compressor Operation) Reversing Valve The reversing valve stays in the last state until a call for heat or cooling.
Compressor Lock Out Time OPERATION The lockout feature ensures that the compressor is de-energized for a period of time. The timer varies randomly from 180 to 240 seconds.
OPERATION Remote Wall Thermostat All Friedrich Vert-I-Pak units are factory configured to be controlled by using a single stage heat/cool remote wired wall mounted thermostat. Thermostat Selection Friedrich recommends the use of the Friedrich RT4 and RT6. These thermostats are single stage heat/cool, manual changeover. The RT4 is a digital display thermostat with single speed fan control.
OPERATION Remote Wall Thermostat Location The thermostat should not be mounted where it may be affected by drafts, discharge air from registers (hot or cold), or heat radiated from the sun appliances, windows etc.. The thermostat should be located about 5 Ft. above the floor in an area of average temperature, with good air circulation. Mercury bulb type thermostats MUST be level to control temperature accurately to the desired set-point. Electronic digital type thermostats should be level for aesthetics.
OPERATION Unit Heat Control Operation - Heat Pump With Electric Heat Automatic Emergency Heat If the sealed system fails with a bad reversing valve or anything that causes the indoor coil to get colder than the indoor ambient temperature: 1) If the indoor coil thermistor senses a 5 degree temperature drop as compared to the ambient temperature thermistor and this lasts up to 5 minutes, the control board will switch the unit to electric heat and continue heating with it.
Refrigeration Sequence Of Operation OPERATION A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difficult and time consuming, if not (in some cases) entirely impossible. The refrigeration system uses four basic principles in its operation which are as follows: 1. “Heat always flows from a warmer body to a cooler body.” 2.
Coils & Chassis Routine Maintenance NOTE: Do not use a caustic cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser. The use of harsh cleaning materials may lead to deterioration of the aluminum fins or the coil end plates. The indoor coil and outdoor coils and base pan should be inspected periodically (annually or semi-annually) and cleaned of all debris (lint, dirt, leaves, paper, etc.) as necessary. Under extreme conditions, more frequent cleaning may be required.
REMOVE AND INSTALL THE CHASSIS Remove The Chassis WARNING ELECTRIC SHOCK HAZARD Turn off electric power before service or installation. All electrical connections and wiring MUST be the National Electrical Code and all local codes which have jurisdiction. Failure to do so can result in personal injury or death. WARNING CUT/SEVER HAZARD Be careful with the sharp edges and corners. Wear protective clothing and gloves, etc. Failure to do so could result in serious injury.
R-410A SEALED SYSTEM REPAIR WARNING Refrigeration system under high pressure O service this equipment. R410A systems operate at higher pressures than R22 equipment. Appropriate safe service and handling practicces must be used. Only use gauge sets designed for use with R410A. Do not use standard R22 gauge sets. The following is a list of important considerations when working with R-410A equipment 1. R-410A pressure is approximately 60% higher than R-22 pressure. 2.
R-410A SEALED SYSTEM REPAIRS WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants.
R-410A SEALED SYSTEM REPAIRS Undercharged Refrigerant Systems WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants.
R-410A SEALED SYSTEM REPAIRS Overcharged Refrigerant Systems WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants.
R-410A SEALED SYSTEM REPAIRS Restricted Refrigerant System Troubleshooting a restricted refrigerant system can be difficult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions. A partial restriction allows some of the refrigerant to circulate through the system. With a complete restriction there is no circulation of refrigerant in the system.
R-410A SEALED SYSTEM REPAIRS Sealed System Method of Charging/ Repairs WARNING CAUTION BURN HAZARD Proper safety procedures must be followed, and proper protective clothing must be worn when working with a torch. FREEZE HAZARD Proper safety procedures must be followed, and proper protective clothing must be worn when working with liquid refrigerant. Failure to follow these procedures could result in moderate or serious injury.
EXTERNAL STATIC PRESSURE External Static Pressure can best be described as the pressure difference (drop) between the Positive Pressure (discharge) and the Negative Pressure (intake) sides of the blower. External Static Pressure is developed by the blower as a result of resistance to airflow (Friction) in the air distribution system EXTERNAL to the VERT-I-PAK cabinet. Resistance applied externally to the VERT-I-PAK (i.e. duct work, filters, etc.
