EVAPORATOR BLOWERS
K2EU060, K4EU090, K3EU120 &
K3EU180
5 THRU 15 NOMINAL TONS
FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
DESCRIPTION
These completely assembled units include a well-insulated cabinet, a
DX cooling coil with copper tubes and aluminum fins,
valve(s), distributor(s), throwaway filters, a centrifugal blower, a blower
motor, an adjustable belt drive, a blower motor contactor and a small
holding charge of refrigerant-22.
The units are shipped in the vertical position ready for field installation.
They can be installed for horizontal operation by reversing the position
of the solid bottom panel with the return air duct flange on the front of
the unit.
ACCESSORIES—FIELD INSTALLED
SUPPLY AIR PLENUMS
These fully insulated plenums are available for free standing units
located within the conditioned space, are shipped knocked-down for
easy field assembly, are finished to match the exterior of the basic
unit, and have double deflection grills that can be adjusted to vary the
throw, spread and drop of the supply air.
RETURN AIR GRILLS
These expanded metal grills are available for free standing units
located within the conditioned space, are finished to match the exterior
of the basic unit and are shipped in one piece for easy installation.
BASES
Bases are available to raise vertical units above the floor. Outdoor air
may be introduced through these bases by cutting an access opening
to accommodate the outdoor air duct connection. These bases are fin-
ished to match the exterior of the basic unit. They may have to be insu-
lated in the field for certain applications.
THREE-PHASE ELECTRIC HEATERS
Electric heaters are available in several capacities to provide maxi-
mum flexibility. Both the air conditioning unit and the heater can be
selected to precisely match the cooling and heating requirements of
the conditioned space. These heaters are designed for easy field
installation over the supply air opening of the unit. They have been
tested by and will be shipped with a CSA label. Every heater will be
fully protected against excessive current and temperature by fuses
and two high limit thermostats.
Units with electric heat will require only one power supply for both the
heating elements and the supply air blower motor, and the power wir-
ing can be protected by either dual element/time delay fuses or an
inverse time circuit breaker.
