10. Provide ready access to water valves and fittings, and screw-
driver access to unit side panels, discharge collar, and all
electrical connections.
11. Where access to side panels is limited, pre-removal of the
control box side mounting screws may be necessary for
future servicing.
3.2.1 - Storage
If the equipment is not needed immediately at the jobsite, it
should be left in its shipping carton and stored in a clean, dry area
of the building or in a warehouse. Units must be stored in an
upright position at all times. If carton stacking is necessary, stack
units a maximum of three high. Do not remove any equipment
from its shipping package until it is needed for installation.
3.2.2 - Protection
Once the units are properly positioned on the jobsite, cover
them with either a shipping carton, vinyl film, or an equivalent
protective covering. Cap open ends of pipes stored on the jobsite.
This precaution is especially important in areas where painting,
plastering or spraying of fireproof material, etc. is not yet com-
plete. Foreign material that accumulates within the units can
prevent proper start-up and necessitate costly clean-up operations.
Before installing any of the system components, be sure to
examine each pipe, fitting and valve, and remove any dirt or
foreign material found in or on these components.
CAUTION: DO NOT store or install units in corrosive environ-
ments or in locations subject to temperature or humidity
extremes (e.g., attics, garages, rooftops, etc.). Corrosive con-
ditions and high temperature or humidity can significantly
reduce performance, reliability, and service life. Always
move units in an upright position. Tilting units on their sides
may cause equipment damage.
3.2.3 - Inspect unit
To prepare the unit for installation, complete the procedures
listed below:
1.
Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the correct
unit has been shipped.
2.
Verify that the unit is the correct model for the entering
water temperature of the job.
3.
Do not remove the packaging until the unit is ready for
installation.
4.
Verify that the refrigerant tubing is free of kinks or dents,
and that it does not touch other unit components.
5.
Inspect all electrical connections. Be sure connections are
clean and tight at the terminals.
6.
Compressors are internally isolated. Compressors equipped
with external spring vibration isolators must have bolts
loosened and shipping clamps removed.
7.
Remove any blower support cardboard from inlet of the
blower.
8.
Locate and verify any accessory kit located in compressor
section.
9.
Remove any access panel screws that may be difficult to
remove once unit is installed.
