5.3.3 Heater Alignment Procedure

It is required to check heater alignment after replacing the dovetail rails, lower heater housing or any other
part that can affect the distance and angle between the heating element and the center of the bed. Heater
alignment is also required after the installation of wall mount models. Removing Wall Mount Warmer from
the bracket and installing it back on the bracket does not require re-alignment

Remove the upper heater housing. Refer to

section 5.3.1

Fit the alignment laser in to the laser holder. Turn laser about 1/8th turn to seat it in the bore of the laser
holder. (Refer to

section 2.1.2.3

for the laser tool part number).

For bedded models, remove mattress, mattress support, translation deck and x-ray tray as needed.
Remove the mattress and translation deck so you can see the circle target stamped in the bed’s center.

Note:

If the laser dot is within the target area no further action is required.

Note:

Standard laser tool batteries require replacement after approximately 20 minutes of use.

For Freestanding model, lock the warmer casters and then locate and mark the alignment spot on the
floor as illustrated in

Figure 5-2

. The alignment spot shall be at 33” +/- 0.1” (84 cm +/- 0.25 cm) distance

from the front side of the rails and at 0.75” +/- 0.1” (1.9 cm +/- 0.25 cm) distance from the center of the
warmer unit.

Note:

Use a laser level (with two wall leveling capability) or a combination of T-square and Plumb-bob to
locate the alignment spot on the floor accurately.

For Wall mount models, locate and mark the alignment spot as illustrated in

Figure 5-3

(for installations

using a bassinet) or

Figure 5-4

(for installations using a fixed surface).

For installations to be used with bassinets, the alignment spot shall be at 40.5” +/- 0.1” (103 cm +/- 0.25
cm) distance from the wall and at 0.75” +/- 0.1” (1.9 cm +/- 0.25 cm) distance from the center of the
warmer unit.
For installations to be used with fixed surfaces, the alignment spot shall be at 25.75” +/- 0.1” (65 cm +/-
0.25 cm) distance from the wall in line with the center of the warmer unit.

Note:

Use a laser level (with two wall leveling capability) or a combination of T-square and Plumb-bob to
locate the alignment spot accurately.

Note:

Make sure the alignment spot location is measured from the wall, not the baseboard.

Use a long 3 mm hex key to adjust the dish’s 3 adjustment screws located in the bosses underneath the
cotter pins. Loosening or tightening the 2 screws on either side will move the laser spot from left to
right, with longitudinal shift, and adjusting the screw in back moves the spot up and down in the target.
Adjust the side screws first, then adjust the bottom screw, so that the laser spot is near the center of the
target circle for bedded models and on the marked alignment spot on the floor for freestanding and
wall mount models.
