board (Figure 4, Item 5) and from Fig. 8, Items 2, 3, 4.
4. Remove existing power cable (See Figure 4, Items
2, 3, and 4) from terminal block and pull out of
Warming Cabinet through 3/8” connector (See Fig.
8, Item 1).
5. Feed facility wiring cable back through the 3/8”
connector (See Fig. 8, Item 1) in the back of the
cabinet and wire onto terminal board as shown in
Fig. 8. Tighten the 3/8” to securely hold the facility
wiring in place.
6. On the terminal board, The green wire (Item 4)

DO NOT WARM -
• Synthetic blend fabrics
• Flammable liquids
• Items containing non-thermal plastic, rubber,
metal snaps, studs, hooks, etc.
Recommended Settings
MAC Medial, Inc. does not recommend chamber
set points for any items that are to be warmed. For
appropriate heating temperatures, please contact
the item manufacturers. For more information, please
contact MAC Medical, Inc.
For blankets, follow blanket manufacturer’s
instructions for the set point.
For intravenous and irrigation uids, follow
temperature guidelines printed on the container or
contact your supplier for temperature and expiration
periods.
loading Contents in Cabinet
Load contents into the chamber with a minimum of 1
inch of space between all walls and fan to allow for
evenly distributed circulation (as seen here).
Allow 1” of spacing between uid containers for
evenly distributed heating (Fig. 9). Avoid stacking
uid bags as this increases the heating time required
to achieve set temperatures.
Blankets must be folded and stacked to allow a one
inch minimum space from the sides, back and top
of the compartment or the shelf above. Do not let
blanket protrude past the front edge of the shelf.
DO nOT OVeRlOAD.
Once a set temperature is selected and obtained
it will be controlled throughout the operations
within ± 1°F to 3°F (-1.7°C to -1.6°C) of the selected
temperature.
From a cold start, each compartment’s loaded
contents will be evenly heated to a set point within 2
to 6 hours (depending on the load). In the event of
power loss, the warmer will resume normal function
once power is restored.
For multi-chambered units, each chamber can be
loaded with different goods and set at different
temperature settings.
In Case of Power failure
In case of power failure, the unit will resume normal
operation when power is restored.
Follow the uid manufacturer’s guidelines for unused
solutions that have cooled or have been removed
from heated storage.
