6.5 Additional Unit Preparation Considerations
For proper installation the following items must be con-
sidered prior to moving the unit to its installation site:
Pursuant to Florida Building Code 13-610.2.A.2.1, this
•
unit meets the criteria for a factory sealed air handler.
If a side return is needed for your application, the side
•
return MUST be prepared prior to moving the air han-
dler to its installation location. See the Side Return Kit
# BAYSRKIT100A Installer Guide for detailed instruc-
tions.
Study the unit’s outline drawing and dimensions prior
•
to selecting the installation site. Note in advance
which electrical conduit entry points and condensate
drain holes are to be used, so that proper clearance
allowances can be made for installation and future
maintenance.
Installation of the air handler must be made prior to,
•
or at the same time as, the installation of the outdoor
unit in order to allow access for refrigerant lines.
Consider the overall space needed when external
•
accessories are used, additional height and width
requirements may exist.
These units are not approved for outdoor installation.
•
These units must be installed in the proper air flow
•
direction.
Any third-party heater accessories, including
•
hydronic coils and duct heaters must be downstream
of the unit.
Note: No atomizing style humidifier is allowed in the
•
return plenum with the use of this unit.
Excessive bypass air may cause water blow-off,
•
which will adversely affect system operation and air
cleaner performance. To verify bypass airflow, fol-
low the Bypass Humidifier Pre-Installation Checkout
and Set-Up Procedures available through your local
distributor. Ask for publication number 18-CH37D1-*
Steam and Flow-through Fan Power Duct-mounted
Humidifiers. Follow the humidifier installation instruc-
tions. These should only be installed on the supply
air side of the system.
Note:
The air handlers have been evaluated in accor-
dance with the Code of Federal Regulations, Chapter
XX, Part 3280 or the equivalent. “SUITABLE FOR
MOBILE HOME USE.”
