General Installation Checks
The checklist below is a summary of the steps required to
successfully install a commercial unit. This checklist is
intended to acquaint the installing personnel with what is
required in the installation process. It does not replace the
detailed instructions called out in the applicable sections
of this manual.
1.
Remove packaging and inspect the unit. Check the unit
for shipping damage and material shortage; file a
freight claim and notify appropriate sales
representation.
Note:
The VSV units have been tied to the skid by (2)
shipping bolts. The removal of these bolts will
require a 3/8 inch (9.7 mm) ratchet with a ½ inch
(12.7 mm) socket.
Note:
The VSH units have been secured to the skid by
shipping brackets. The removal requires a ½”
socket with a 3/8” ratchet.
2. Verify the correct model, options and voltage from the
unit nameplate.
3. Pull out all field attached parts (i.e. filter rack, duct
collar, filter and mounting screws) from the unit
packaging for field mounting.
4. Verify the installation location of the unit will provide
the required clearance for proper operation.
5. Remove refrigeration access panel and inspect the
unit. Be certain the refrigerant tubing has clearance
from adjacent parts.
Note:
Removal of compressor shipping brackets is
required on models VSHE 042, 050, 060 &
VSVE060. The removal of the shipping brackets
requires a 1/2” socket with a 3/8” ratchet. A bracket
is provided on the right and left side of the
compressor and requires the removal of 4 bolts per
bracket.
6. Fabricate and install duct work.
7.
Install and connect a condensate drain line and trap to
the drain connection.
Main Electrical
8. Verify the power supply complies with the unit
nameplate specifications.
9. Inspect all control panel components; tighten any
loose connections.
10. Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect switch
and to the power block.
11. Install proper grounding wires to an earth ground.
VSV/VSH 460V units require a neutral (a four wire
system).
Note:
All field-installed wiring must comply with NEC
and applicable local codes.
Low Voltage Wiring (AC) Requirements
12. Install the zone sensor.
13. Connect properly sized control wiring to the proper
termination points between the zone sensor and the
unit control panel.
Filter Installation
14. Each unit ships with 1 inch or 2 inch disposable, MERV
8 or MERV 13 filter(s). The filter is factory installed.
Note:
Do not operate the unit without filters.
Supply-Air Ductwork
Install the 1 inch supply-air duct flange to the unit with the
(8) 5/16 inch factory supplied head screws.The duct collar
assembly for each unit is shipped with the unit in the same
box where the IOM manual is located.
When attaching the field ductwork to the unit, provide a
watertight flexible connector at the unit to prevent
operating sounds from transmitting through the
ductwork. See
Figure 21, p. 40
.
Elbows with turning vanes or splitters are recommended
to minimize air noise due to turbulence and to reduce static
pressure.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow codes could result in death or serious injury.
