PRE-INSTALLATION
GENERAL
The KLPS, KLPS-D, KQFS, KQFS-FA & QFC constant volume
(series) and KLPP, KQFP & QFV variable volume (parallel) fan
powered boxes (see Figure 1 & 2) are equipped to provide
pressure independent, variable volume (VAV). The units can
also be equipped with factory-installed Analog, Pneumatic,
or field supplied direct digital controls. Units are available
with factory-installed electric or hot water heat.
CONTROL OFFERINGS
Each KLPS, KLPS-D, KLPP, KQFS, KQFS-FA, KQFP, QFC &
QFV unit is supplied with four quadrant multi-point center
averaging airflow sensor as a standard feature. These
sensors offer airflow averaging capability that results in an
airflow sensing capacity equal to any competitive unit.
Control options include pressure independent pneumatic,
analog electronic and field supplied direct digital. Pneumatic
controls are available with linear actuators and single-
function or multi-function controllers. The multi-function
controller provides a simple switchover from normally open
to normally closed applications. Electronic control units
feature a factory-installed enclosure that provides easy
access for field connections.
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 units. 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.
Air-handling equipment will provide safe and reliable service
when operated within design specifications. The equipment
should be operated and serviced only by authorized
personnel who have a thorough knowledge of system
operation, safety devices, and emergency procedures. Good
judgment should be used in applying any manufacturer’s
instructions to avoid injury to personnel or damage to
equipment and property.
WARNING: 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.
WARNING: If it is necessary to remove and dispose of
mercury contactors in electric heat section, follow
all local, state, and federal laws regarding disposal of
equipment containing hazardous materials.
