Good judgement should be used in applying any
manufacturer’s instructions to avoid injury to personnel
or damage to equipment and property.
WARNING
35KA,KN,KP06-18
Bypass Terminal Units
for Variable Air Volume Systems
Disconnect all power to the unit before performing maintenance or service. Unit may automatically start if power is
not disconnected. Electrical shock and personal injury
could result.
PRE-INSTALLATION
General —
terminal available with factory-installed pneumatic or analog
electronic control options. Figure 1 shows the basic box.
STORAGE AND HANDLING — Inspect for damage upon
receipt. Shipping damage claims should be filed with shipper at
time of delivery. Store in a clean, dry, and covered location. Do
not stack cartons. When unpacking units, care should be taken
that the inlet collars and externally mounted components do not
become damaged. Do not lift units using collars, sensors or externally mounted components as handles. If a unit is supplied
with electric or hot water heat, care should be taken to prevent
damage to these devices. Do not lay uncrated units on end or
sides. Do not stack uncrated units over 6 ft high. Do not handle
control boxes by tubing connections or other external attachments. Table 1 shows component weights.
INITIAL INSPECTION — Once items have been removed
from the carton, check carefully for damage to duct connections, coils or controls. File damage claim immediately with
transportation agency and notify Carrier.
UNIT IDENTIFICATION — Each unit is supplied with a
shipping label and an identification label. See Fig. 2.
INSTALLATION PRECAUTION — Check that construction debris does not enter unit or ductwork. Do not operate the
central-station air-handling fan without final or construction
filters in place. Accumulated dust and construction debris
distributed through the ductwork can adversely affect unit
operation.
SERVICE ACCESS — Provide service clearance for unit
access.
CODES — Install units in compliance with all applicable
code requirements.
The 35K unit is a single duct, variable volume
