The new Friedrich Vert-I-Pak has state of the art features to improve guest comfort and conserve energy. Through
the use of specically designed control software, Friedrich has accomplished what other Manufacturer’s have only
attempted – a quiet, dependable, affordable and easy to use Vert-I-Pak.
Below is a list of standard features on every Friedrich VPAK and their benet to the owner.
Quiet 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 ve seconds prior to en-
ergizing the compressor. Also, the fan off delay allows for “free cooling” by utilizing the already cool indoor
coil to its maximum capacity by running for 30 seconds after the compressor.
Remote Thermostat
Operation
VPAK units are thermostat controlled.
Internal Diagnostic
Program
The new Friedrich digital VPAK features a self diagnostic program that can alert maintenance to compo-
nent failures or operating problems. The internal diagnostic program saves properties valuable time when
diagnosing running problems.
Service Error Code
Storage
The self diagnosis program will also store error codes in memory if certain conditions occur and correct
themselves such as extreme high or low operating conditions or activation of the room freeze protection
feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an error
occurred and corrected itself.
Room Freeze
Protection
When the VPAK senses that the indoor room temperature has fallen to 40°F the unit will cycle on high fan
and the electric strip heat to raise the room temperature to 46°F then cycle off again. This feature works
regardless of the mode selected and can be turned off. The control will also store the Room Freeze cycle
in the service code memory for retrieval at a later date. This feature ensures that unoccupied rooms do not
reach freezing levels where damage can occur to plumbing and xtures.
Random
Compressor Restart
Multiple compressors starting at once can often cause electrical overloads and premature unit failure.
The random restart delay eliminates multiple units from starting at once following a power outage or initial
power up. The compressor delay will range from 180 to 240 seconds.
Digital Defrost
Thermostat
The new Friedrich VPAK uses a digital thermostat to accurately monitor the outdoor coil conditions to allow
the heat pump to run whenever conditions are correct. Running the VPAK in heat pump mode save energy
and reduces operating costs. The digital thermostat allows maximization of heat pump run time.
Instant Heat
Heat Pump Mode
Heat pump models will automatically run the electric heater during compressor lock-out to quickly provide
heat when initially energized, then return to heat pump mode. This ensures that the room is heated quickly
without the usual delay associated with heat pump units.
Emergency Heat
Override
In the event of a compressor failure in heat pump mode the compressor may be locked out to provide heat
through the resistance heater. This feature ensures that even in the unlikely event of a compressor failure
the room temperature can be maintained until the compressor can be serviced.
Desk Control Ready
All electronic VPAK units have low voltage terminals ready to connect a desk control energy management
system. Controlling the unit from a remote location like the front desk can reduce energy usage and
requires no additional accessories at the VPAK.
Indoor Coil Frost
Sensor
The frost sensor protects the compressor from damage in the event that air ow is reduced or low outdoor
temperatures cause the indoor coil to freeze. When the indoor coil reaches 30
°F the compressor is
diabled and the fan continues to operate based on demand. Once the coil temperature returns to 45°F the
compressor returns to operation.
Ultra-Quiet Air
System
The VPAK series units feature a indoor fan system design that reduces sound levels without
lowering airow and preventing proper air circulation.
High Efciency
The VPAK benets quality components and extensive development to ensure a quiet, efcient and
dependable unit.
Rotary Compressor
High efciency rotary compressors are used on all Friedrich VPAKs to maximize durability and efciency.
Auxiliary Fan Ready
The VPAK features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to
adjoining rooms. Auxiliary fans can provide conditioning to multiple rooms.
