FINAL INSPECTION & START-UP
Before Operating The Unit
1.
Install unit per the instructions outlined in this manual
and all applicable local and national codes.
2.
Verify electrical supply matches electrical requirements
of the unit, and unit is properly grounded.
3.
Examine control box. Verify all wire connections are
secure, and control board jumpers are in proper
positions.
4.
Verify chassis is properly fitted to wall sleeve and
securely mounted to surrounding framing.
5.
Verify chassis is level: Pour water into drain pan.
Verify it flows through the drain hoses to condenser
side of unit.
6.
Verify indoor blower wheels and outdoor fan blades are
secured to their motor shafts, and rotate freely.
7.
Verify all sheet metal panels are in place and secure.
8.
Attach front panel to the existing cabinet enclosure.
9.
Verify nothing interferes with room discharge air or
return air of units.
Examples:
Check for curtains or drapes that obstruct air flow. See
Figure 10 and Figure 11.
Check for plush carpeting that can obstruct return air.
These types of obstructions can cause serious damage
to the chassis.
Any obstruction of supply air, including use of deflector
baffles, may cause condensate to form on louver or
cabinet. See Figure 11.
For optimum performance of your PTAC/PTHP, avoid
restricting the air flow. Position of curtains or drapes
over supply air grille may cause air to recirculate without
cooling the room. Unit will short cycle and may cause
premature compressor failure. See Figure 11.
