SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment (Fig. 1-4)
can be hazardous due to system pressures, electrical compo-
nents, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service technicians
should install, start up, and service this equipment.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling, rigging, and setting bulky
equipment.
.
GENERAL
These installation instructions cover the 30MPA, MPW units
with
Comfort
Link controls. The 30MPA units are condenserless
units and the 30MPW units are fluid cooled. See Fig. 1-4 for dif-
ferent unit configurations. See Fig. 5 for model number no-
menclature and Fig. 6-19 for unit dimensional details and cor-
ner weights.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-
gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrig-
erant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec-
essary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all discon-
nect locations to alert others not to restore power until work
is completed.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these proce-
dures may result in damage to equipment.
