Introduction, Warning, Cautions, and Notices
SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical
shock, or other conditions which may cause death, personal
injury, or property damage. Consult a qualified installer,
service agency, or your distributor or branch for information
or assistance. The qualified installer or agency must use
factory−authorized kits or accessories when modifying this
product. Refer to the individual instructions packaged with
the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Use quenching cloth for brazing
operations. Have fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit. Consult local
building codes and current editions of the National
Electrical Code (NEC) NFPA 70. In Canada, refer to current
editions of the Canadian electrical code CSA 22.1.
EQUIPMENT ELECTRICAL
DISCONNECTS
When installing equipment, a service disconnect must be
installed in the fixed wiring in accordance with local
electrical code.
CLEARANCE REQUIRMENTS
When installing, allow sufficient space for airflow
clearance, wiring, refrigerant piping, and service. Allow 36
in. clearance to service end of unit and 72in. above unit
without any major air flow obstructions. For proper airflow,
a 48in. clearance all remaining sides must be maintained.
Position so water, snow, or ice from roof or eaves cannot
fall directly on unit. Never install equipment indoors or in
areas with improper venting to environment.
EQUIPMENT INSTALL
Equipment MUST be installed on a level and solid surface.
WARNING
Failure to follow this
warning could result in
personal injury or death.
Before installing,
modifying, or servicing
system, main electrical
disconnect switch must be
in the OFF position. There
may be more than 1
disconnect switch. Lock out
and tag switch with a
suitable warning label
ELECTRICAL SHOCK HAZARD
Failure to do so can result in improper oil distribution in
compressors and will terminate factory warranty. Anchor
bolts must be used in the provided locations on each of the
mounting feet (refer to fig. 1 for details). For hurricane tie
downs, contact a local distributor for details and PE
(professional Engineer) certification, if required by local
authorities.
On rooftop applications, mount on level platform or frame.
Place unit above a load−bearing wall and isolate unit and
piping set from structure. Arrange supporting members to
adequately support unit and minimize transmission of
vibration to building. Consult local codes governing rooftop
applications.
COMPRESSOR CRANKCASE HEATER
When equipped with a crankcase heater, furnish power to
heater a minimum of 12 hrs. before starting unit. To apply
power to the heater only, set low voltage breaker
(CB6) to off and the compressor breakers (CB1
and CB2) to the on position. Close all cabinet
covers during the waiting period to prevent burns or
electrical shock.
3 - PHASE MONITOR
In 3 - phase equipment, a small circuit board is factory
installed to prevent incorrect rotation of motors. A small
LED will flash if a phase problem exist. Depower the
equipment by switching the appropriate disconnect and
interchange two of the field wiring leads on the distribution
block.
WARNING
Failure to wear proper PPE for the job being
undertaken could result in death or serious injury.
Technicians, in order to protect themselves from
potential electrical, mechanical, and chemical hazards,
MUST follow precautions in this manual and on the
tags, stickers, and labels, as well as the instructions
below:
•
Before installing/ servicing this unit, technicians
MUST put on all PPE required for the work
( Examples; cut resistant gloves/ sleeves, safety
glasses, hard hat/bump cap, fall protection,
electrical PPE, and arc flash clothing) ALWAYS
refer to appropriate Material Safety Data Sheets
and OSHA guidelines for proper PPE.
•
NEVER perform any switching, disconnect, or
voltage testing without proper electrical PPE and
arc flash clothing. Ensure electrical meters and
equipment are properly rated for intended
voltage.
