vPC / vPP, and vPH models provide a complete air-conditioning and optional heating system as an all-in-one pack-
age, capable of providing total heating and cooling functions for a single zone or multiple rooms. Specifically designed
for convenient through-the-wall installation in residential high rise and hospitality industry applications. The all-indoor
design eliminates the need for unsightly exterior equipment, thereby maintaining architectural esthetics.
all units are shipped completely wired and factory tested. The refrigeration section features enhanced refrigeration
coils, a bi-flow thermostatic expansion valve for refrigerant control, and a high efficiency Scroll or rotary compres-
sor. The vPP units incorporate a reversing valve to allow operation on a heat pump cycle. air circulating fans are
centrifugal, direct driven. The indoor fan motor allows operation at three different fan speeds.
The standard vPC & vPH units may be operated on the cooling cycle to an outdoor ambient of 40ºF. The low ambient
cooling package will cycle the compressor to prevent frosting of the evaporator at low outdoor ambient temperatures.
The vPP unit locks out compressor operation (refrigerant heating) at outdoor ambient temperatures below 40ºF.
