door tie-back brackets that are shipped along with
the unit.
Service valves and sight glasses
Suction, discharge, and liquid line valves are
provided as an option for isolation, monitoring
pressures, reclamation, and charging of refrigerant
to minimize downtime and simplify service and
repair. A sight glass is a standard feature on all
units and is located in an easy access area for quick
inspection of refrigerant in the unit. Units with
replaceable core filter driers include liquid line
valves in the upstream and downstream section to
allow for ease of maintenance.
Convenience outlet
For maintenance tasks requiring power tools, an
optional 115 V, 15 amp GFCI continuous duty outlet
can power lights, drills, or any other power hand
tools needed.
Condenser safety tie-off
The unit is provided with a condenser safety tie-
off on the condenser section roof as standard on
all units. A safety harness can be secured by the
operator to the tie-off while servicing the unit to
prevent an accidental fall from the unit.
Condenser cleaning hatch
Periodic cleaning of condenser coils has never been
easier. The 25 ton to 60 ton units (Figure 59 and
Figure 60) are provided with hatches on both sides
of the condenser frame. On 70 ton to 80 ton units
(Figure 61), the dual hatches are provided on the
accessible section of the condenser.
Burglar bars
The units are designed to provide the customer
peace of mind. Intrusion through the ductwork
is prevented by installing burglar bars in the
accessible sections with a bottom opening.
Inlet, belt guard and spare belts
To ensure operator safety, optional inlet guards
are provided on the supply fan inlet, and optional
belt guards are provided to enclose the drive and
sheave package on the return (25 ton to 50 ton) and
exhaust (25 ton to 80 ton) fan. A spare set of belts
for the return (25 ton to 50 ton) and exhaust (25 ton
to 80 ton) fan are available as a ship loose option.
Start-up and air balancing wizard
One of the most critical phases of the unit's life is
during installation and start-up. Proper start-up
ensures the unit operates without any trouble. The
unit controller has a start-up wizard, which ensures
field technicians follow all start-up procedures as
mandated by the start-up documentation. All testing
data is stored and can be downloaded to a USB.
For any unit that has dampers, fans, or airflow
measurement stations, air balancing is critical. The
unit controller has an air balancing wizard that
assists both technicians and commissioning agents
to test and calibrate airflow.
Factory run-tested
Each unit is subjected to a series of quality
assurance checks as well as an automated quality
control process before being run-tested. Fans and
drives are checked for proper balancing at the
factory during testing. The factory run-test ensures
safe, proper operation when the unit is installed and
reduces installation and commissioning time.
