"Oil-Less" Scroll Laboratory Air
2.0 Installation
2.1 Inspection Upon Receiving
The condition of the Scroll Laboratory Air system
should be carefully inspected upon delivery. Any
indication of damage by the carrier should be noted
on the delivery receipt, especially if the system will
not be immediately uncrated and installed. Scroll
systems may remain in their shipping containers
until ready for installation. If Scroll systems are
to be stored prior to installation, they must be
protected from the elements to prevent rust and
deterioration.
DO NOT REMOVE the protective covers from the
inlet and discharge connection ports of the unit
until they are ready for connecting to the hospital's
pipeline distribution system.
2.2 Handling
WARNING:
USE APPROPRIATE LOAD RATED LIFTING
EQUIPMENT AND OBSERVE SAFE LIFTING
PROCEDURES DURING ALL MOVES.
The compressor package can be moved with
either a forklift or dollies. Be sure that the orange
spacers used to prevent the compressor and motor
assemblies from fl oating are in place, as well as
the dryer spacer on 2 - 7.5 hp systems. These
spacers will prevent unnecessary movement while
moving and mounting the unit. Keep all packing
in place during installation to minimize damage.
Walk along the route the unit must travel and note
dimensions of doorways and low ceilings. Scroll
2 - 7.5 hp systems are designed to go through 36"
doorways. Scroll 10 hp systems must be separated
to go through 36" doorways.
If the system must be separated, carefully label all
electrical connections that are removed for easier
re-assembling at the fi nal destination. Place units
to ensure high visibility of indicators and gauges
and for performing maintenance on the system.
2.3 Location
The Scroll Laboratory Air system should be
installed indoors in a clean, well-ventilated
environment. Areas of excessive dust, dirt or other
air-borne particulate should be avoided.
Secure the package to a fl at, level surface capable
of supporting the weight and forces of the unit.
Make sure that the main base is not bowed,
twisted, or uneven. Because of the internal fl exible
hose connections and spring isolators, no special
foundation is required. However, the unit base
must be securely bolted using all mounting holes
provided in the base. If a raised concrete pad is
used, the base must not overhang the concrete
pad. A method to drain away moisture is necessary.
If a gravity drain is not available, a connection to
a drain is necessary. After securing the unit to the
fl oor, remove the orange spacers from under the
compressor/motor structure.
The area should have an average ambient
temperature of 70°F (21°C) with a minimum
ambient temperature of 40°F (4.4°C) and
a maximum ambient temperature of 105°F
(37.8°C). (Note: At temperatures below 32°F the
bare compressor will not be adversely aff ected,
but freezing of the condensate can occur which
could aff ect operation.)
Sound levels of 65 to 80 dbA are to be anticipated
depending on the size of the package (duplex,
triplex, quad). Though the sound levels are
not excessive, they should be considered when
locating the system.
