York Evaporator Blowers K3eu120 User Manual

036-21300-002-A-0905

DESCRIPTION

These completely assembled units include a well-insulated cabinet, a

DX cooling coil with copper tubes and aluminum fins, expansion

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

SPLIT-SYSTEM

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.

5 THRU 15 NOMINAL TONS

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.

THERMOSTATS

ACCESSORIES-FIELD INSTALLED (CONT.)

Wall-mounted thermostats and subbases (24-volt) with sys-

tem and fan switches are available to control the operation of

these split system air conditioners.

HOT WATER COILS

These drainable coils have 2 rows of 1/2" copper tubes, 12

aluminum fins per inch, a casing that is finished to match the

exterior of the basic unit, but no water control valve. The coils

slide out of their casings for easy field installation. They

should be mounted over the return air opening on 5, 7-1/2

and 10-ton units—between the unit coil and blower sections

on 15-ton units.

APPLICATION FLEXIBILITY

MODELS 5, 7-1/2 & 10 TON

These units are built in a single cabinet with two condensate

drain pans. This allows the units to be installed in either the

vertical or horizontal position for maximum flexibility.

STEAM COILS

On vertical applications, the air velocity across the cooling

coil keeps the condensate from dripping off the finned sur-

face onto the filters.

These non-freeze coils have 1 row of 1" copper tubes, a 5/8"

copper tube inside each 1" tube to distribute the steam evenly

across the entire length of the coil, 8 aluminum fins per inch,

a casing that is finished to match the exterior of the basic unit,

but no steam control valve. The coils slide out of their casings

for easy field installation and are pitched in their casings to

facilitate condensate drainage. They should be mounted over

the return air opening on 5, 7-1/2 and 10-ton units—between

the unit coil and blower sections on 15-ton units.

On horizontal applications, the unit must be installed with the

condensate drain pan under the entire cooling coil.

•

The Supply Air Plenum and the Return Air Grill accesso-

ries can be used on either arrangement.

The Base accessory can only be used on the vertical

arrangement.

•

SUSPENSION KIT

Units installed horizontally are designed for ceiling suspen-

sion. Four 3/8"-16 weld nuts are provided in the angle sup-

ports on the front of the unit (the side with the logo).

Knockouts are provided in the exterior panels for access to

these weld nuts. The hanger rods must be supplied in the

field.

Suspension kit 1HH0451 is available for 15-ton units installed

horizontally. The accessory includes two channel iron sup-

ports and the hardware to secure them to the top of the unit.

The hanger rods must be supplied by the field.

These units have two distinct modules . . . a blower module

and a coil module. Although the unit is always shipped in the

vertical position with a vertical air discharge as shown in illus-

tration (a), the blower module can be repositioned in the field

as shown in illustrations (b) and (c) for maximum flexibility.

1. Adjusting the vertical louvers will vary the throw, the spread and the drop.

2. Adjusting the horizontal louvers will only vary the drop.

3. The velocity of the air will be 125 ft./min. at the minimum distance and 80 ft./min. at the maximum distance.

4. The velocity of the conditioned air at the bottom of the drop will be 50 ft./min. Drafts will occur if the drop extends into the occupied

level of the conditioned space.
