Drukuj stronęThermostats are available from Cold Point Corp. Use of
thermostats not supplied by Cold Point Corp. are the
responsibility of the installer.
Proper temperature control and unit operation
depends on proper thermostat selection and location.
Refer to the thermostat manufacturer's installation
instructions for specific recommendations. Good
practice is to avoid outside walls, locations where the
sun may shine directly on the thermostat, and locations
where the air from supply registers or unit outlets blow
on the thermostat. Also avoid locations where the
thermostat could be jarred by a closing door.
UNIT LOCATION and MOUNTING:
Choose a location that places the CN unit as close to
the indoor unit as possible. The maximum separation
is 100 feet. Maximum vertical lift (compressor above
evaporator) is 35 feet.
Avoid high traffic areas and areas where water, snow,
or ice may fall from a roof onto the unit. In climates
where snow is a consideration, locate the unit away
from areas prone to drifting. For heat pump
installations be sure to raise the unit above expected
snow levels.
For wall mounting, assure that mounting frames and
hardware are corrosion resistant and of adequate size
and strength to support the unit. For ground or roof
mounting provide a level pad or platform.
Insure free flow of air into and out of the unit. Stay
clear of obstructions such as walls and shrubs.
Minimum clearances must be adhered to as illustrated
in Fig. 1 and in accordance with Table 2.

block air flow or in a way that hot air from one unit will

ELECTRICAL WIRING and SUPPLY
VOLTAGE:
All electrical wiring must be run according to NEC and
local codes. Nameplate data indicates the operating
voltage, phase, ampacity, maximum over current
protection, and minimum voltage. Use copper
conductors only.
The contractor is to provide branch circuit over current
protection for the unit as required by code. Run power
supply wiring through a weatherproof disconnect box
and conduit to the unit connection. Disconnects are
required to be within sight and easy reach of the unit,
(usually within 3 feet).
For low voltage wiring use NEC class 2 wire. Check the
unit wiring diagram for the number of conductors
required. Route neatly and protect from sharp edges and
damage.
CN SERIES units are rated for use on 230V power
supply circuits. Unit performance and life depend on a
supply voltage that is maintained between 207V and
253V. Inadequate wiring and/or improper electrical
supply will likely result in failure of the compressor and
other electrical components and voids the Warranty.
REFRIGERANT PIPING:
The length of refrigerant lines and the number of bends
determine the pressure drop which affects capacity and
efficiency of the system and oil return to the compressor.
The outdoor unit connections are sweat type. Tube size
should always be the same diameter as the connections
provided at the service valves. Up sizing of lines can
result in inadequate oil return to the compressor and
excessive refrigerant charge and will void the Warranty.
