AcuAir
®
system installation, operation, and maintenance
involves heavy rotating machinery operating at high speed and
high voltage. Normal operations and maintenance procedures
may require working at elevations, enclosed space entry, or
use of hand and power tools. Taking these considerations into
account along with the hygienic nature of AcuAir
®
applications,
it is clear that safety should always be the top priority.
We recommend that every AcuAir
®
system user analyze and
develop an installation-specic safety regime that takes
into account such variables as specic site/system features,
personnel qualications, hazard identication, etc.
The following elements of operational safety are recommended
for inclusion in every client’s AcuAir
®
system safety plan/
requirements:

 – All fan covers, guards, and shaft retainers (if any)
must be in place before applying power to an AcuAir
®
system.
Always disengage and lock out power before allowing interior
inspections. To prevent foreign objects from being sucked into
rotating fan blades,  allow operation with the doors open.

at a minimum – consult your internal safety policy and OSHA
requirements for additional recommended safety procedures.

emits unusual vibration and noise. The source must be
investigated, identied, and corrected before testing or placing
the system back in operation.

machinery requires care to avoid electrical shocks from
inadequate or loose eld wiring and connections. All personnel
must lock out and tag machinery before working on the unit.
Proper safety precautions such as the use of insulating soles
and gloves and a trained “lookout buddy” are indispensable.
Ice formation in cold weather can present slip and fall hazards.
Icing safety procedures should be mandatory when the daily
ambient temperature falls below 40°F.
AcuAir
®
systems typically serve in a continuous-duty capacity
and must be properly sited, installed, and connected in the
eld (by others) to appropriately sized and installed wiring for
electrical power and controls, air ducting, refrigerant lines, and
fuel piping. The engineering plans, piping layouts, etc. for all
peripheral “eld” work should be detailed in accordance with
local and governing codes and the best industry standards
and practices.
If you have any comments or questions regarding this manual
or the AcuAir
®
system, you are urged to call your installing
contractor and/or sales representative.

All AcuAir
®
systems must be located to minimize the effect
of exhaust air recirculation. Prevailing winds, other structures
or even other air handling units can cause exhausted air to
be drawn back into the AcuAir
®
unit. Short cycling air in this
manner can create an excess cooling load, condensation
load or in cold climates, frost blockages. It is the owner’s
responsibility to properly locate each system and consult with
a qualied engineer before laying out structural or foundation
supports and installing the AcuAir
®
system.
Sufcient access must always be available to allow adequate
airow to the AcuAir
®
system fresh air inlet and exhaust
louvers. In general, AcuAir
®
systems should always be placed
on concrete pads, piers or structural steel so that exhaust
air discharge of the fan orice is at or above the elevation of
nearby walls, structures, and equipment.
For other minimum spacing requirements see the generic
layout in Figure 2 for examples showing an AcuAir
®
system
installed next to a wall.

Before nalizing piping installation plans, it is recommended
that related plans for system and plant expansion be discussed
with your refrigeration system designer and Johnson Controls-
Frick
®
sales representative. Incorporating appropriate pipe and
opening sizes now (for existing and future needs) allows for
easier installation in the future.
