The Weather Last feature also insulates and has up to 10 times the acoustic absorption of metal cabinets.
PAGE 8
DURABLE CONTROL PANEL DOOR AND EASY-TO-USE CONTROLS The reinforced control door conceals controls and features an attractive surface that will not chip. The hinge and door are extruded as one piece and provide protection from demanding transient use. The door is sloped to discourage use as a shelf. Easily accessible from the room side, the control buttons and thermostat are clearly marked and simple to use.
PAGE 9
PRODUCT FEATURES AND BENEFITS (cont) EASY ACCESS TO CHASSIS Access to the chassis simply requires removing four screws and then sliding the chassis out of the sleeve for service. Once the power is turned off, connectors can be separated on hard-wire units, or the power cord can be disconnected on cord-connected units. Easy Service Access HIDDEN CONTROLS The factory-wired control box houses all control components and is quickly accessible without removing the chassis from the wall sleeve.
PAGE 10
ENHANCED COPPER TUBING Enhanced copper tubing is more efficient and durable and can be repaired in the field, if required. Because copper is a very stable metal, it is durable and resists corrosion.
PAGE 11
PRODUCT FEATURES AND BENEFITS (cont) HEAT PUMPS PAY THEIR OWN WAY Heat pump models are available at a nominal additional cost. In many locales, the payback is realized in just a few months. Cost and payback details are provided on the next page. How The Heat Pump Works In Hot Weather: In Cool Weather: In Sub-Freezing Weather: Carrier’s Series 52 units provide indoor comfort in the same manner as conventional air conditioners, removing heat and humidity from indoor air.
PAGE 12
HEAT PUMP ENERGY SAVINGS Heat pumps save more on operating costs during the heating cycle than heat/cool models. The table below shows that the higher initial cost of purchasing a heat pump is quickly made up in lower operating costs. Use the map to identify the climate zone’s designated number. Reading down the left-hand column of the table, select the cost/kWh rate in this zone that most closely approximates your local rate.
