PREINSTALLATION REQUIREMENTS

TRAINING & SAFETY CONSIDERATIONS

The AcuAir

precision-engineered hygienic air systems

provided by Johnson Controls-Frick, utilize the finest in HVACR

materials and corrosion protection to deliver dependable,
consistent, and accurate control of temperature and humidity
in process rooms. This manual provides the information
needed for safe installation, operation, and maintenance.
Close attention to the instructions and guidelines provided
will ensure the longest possible system life and dependable,
consistent performance.

CAUTION

Before installing, operating, or maintaining the system,

it is recommended that only experienced

HVACR

contractors, operators, and maintenance technicians

be used (in conjunction with formal training on the

AcuAir

system’s design and features). Reading and

understanding of this manual should serve as the

minimum application-specific training requirement.

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-specific safety regime that takes

into account such variables as specific site/system features,

personnel qualifications, hazard identification, etc.

The following elements of operational safety are recommended

for inclusion in every client’s AcuAir

system safety plan/

requirements:

NOTICE

Configure all power switches and controls to provide an
open, safe circuit before and during maintenance pro

cedures, until the system is cleared by management for

normal on-line operations. For

extended shutdowns, it

is recommended that a qualified technician remove fuses
from “fused-disconnect panels” or otherwise open the

circuit in an accepted, secure manner.

Fans

– 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,

never

allow operation with the doors open.

Enclosed space inspections

– Inspections of coils, filters, etc.,

requires machinery lockout and the use of a “lookout buddy”

at a minimum – consult your internal safety policy and OSHA

requirements for additional recommended safety procedures.

Vibration and noise

– Discontinue or stop machinery that

emits unusual vibration and noise. The source must be

investigated, identified, and corrected before testing or placing

the system back in operation.

Wet Surface Precautions

– Poorly maintained and wetted

machinery requires care to avoid electrical shocks from

inadequate or loose field 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

field (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 “field” 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.

PRELIMINARY SITE LAYOUT CONSIDERATIONS

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 qualified engineer before laying out structural or

foundation

supports and installing the AcuAir

system.

Sufficient access must always be available to allow adequate
airflow 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 orifice 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.

PRELIMINARY FIELD PIPING DESIGN

CONSIDERATIONS

CAUTION

All AcuAir

systems require strongly supported and

properly anchored field piping. NO field piping is to be
supported by the AcuAir

system itself. Wind loading,

temperature variation, etc., must be considered to allow
for movement between the system, adjoining building,
ducting, and field piping. A qualified cooling system
design engineer should provide final field-piping plans
and specifications.

Before finalizing piping installation plans, it is recommended

that related plans for system and plant expansion be discussed
with your refrigeration system designer.
