1. It is recommended that a lift truck be used for installation.
2. Adjust the lift truck height so that the heat exchanger is located in
line with the cutouts and mounting holes.
3. Route the power cord through the air cutout.
4. Move the heat exchanger toward the enclosure panel so that the gap
between the heat exchanger and the enclosure is about .05-inch.
5. Install sealing washers and stainless steel nuts on each screw from
inside the enclosure and tighten (see mounting drawing).
6. Attach overflow drain hose supplied to the drain exit at the bottom of
the unit. This hose
must not
be elevated above the exit port.
Improper mounting will impede the flow of condensate and may
cause internal malfunctions.
7. Attach supply line to 1/2" O.D. copper tubing Inlet on bottom of unit.
8. Attach discharge line to 1/2" O.D. copper tubing Outlet on bottom of
unit.
