Installing the Casing
1. Ensure all preparations are met within the “Prerequisite Section.”
2. Concealed wall must be prefabricated for the entire length of
the casing. Additional wall features must be fitted after the unit
installation is complete.
3. Position the unit so the opening on the casing sits on the edge of
where the outer wall is planned.
4. Bolt the unit to the ground. The brackets are supplied by the
installer and should provide enough support to remove all
vibrational effects.
5. Bring the Removable Chassis within range of the Ice Air casing.
6. Follow “Piping Connection” and “Hose Kit Installation” sections.
7. Secure the Removable Chassis to the unit’s encasing. Follow
“Installing the Chassis” section.
8. The walls are now ready to be installed
9. Attach the Access Panel to the wall and ensure it is aligned to
the casing for access to the control panel and filter.
10. Run the casing.
Piping Connection
Ice Air’s Water Source Heat Pumps are manufactured with a remov-
able chassis for a matching cabinet. The removable chassis houses
the intake and outtake pipes as well as the condensate tubes that
link to the drain pan on the cabinet. Each chassis must be connected
to the risers before installing to the cabinet. Using a Braided Steel
Hose (provided by Ice Air), attach the risers to their respective pipes
(labeled as shown in image below). The removable chassis is now
ready to be installed.
Hose Kit Installation
1. Refer to the hose kit installation detail drawing (below) for an
illustration of a typical supply/return hose kit assembly.
2. Unpack and examine hose kit. Remove all shipping and/
or packing material such as rubber bands, plastic caps, and
Styrofoam. Hose kit should contain (2) hoses.
3. Attach the hoses to the shut-off valves supplied with risers.
Always use a back-up wrench when tightening the hose to
the valve.
4. Attach flex hoses. Let the universal ends of the hoses hang
inside the casing. NOTE: When valves and P/T ports are used,
be sure the valve handles and P/T ports are in a position that
enables them to be opened and closed and used for system
readings after hose installation. Check the swivel ends of the
hoses. Gaskets must be in the hose for proper seal.
5. Slide the chassis partially into the cabinet. Match the SUPPLY
hose to the SUPPLY tube on the chassis and the RETURN hose
to the RETURN tube. Tighten the swivel connections, keeping the
unit copper tubes parallel to the sides of the chassis, and then
tighten the hoses to the copper tubes, making sure the hose
hangs straight without twisting or turning.
NOTE: Always use back-up wrench on the fittings being
tightened.
6. With the hoses properly installed, you can proceed to slide the
chassis into place in the casing.
