HSXB15-024, -030, -036, -042,-048, -060; & HSXA19-036, 038, 048, -060 SERIES UNITS
Package 1 of 1 contains:
1 - Condenser coil
1 - Bag assembly for use with the following units:
HS26-030, -036, -042,-048, & -060; HS27-024, -030,
-036, &-042; HSXA15-060; & HSXB16-060
1 - Discharge line with elbow
1 - Liquid line adapter
All other units:
1 - 1/2" Coupling
Check the replacement coil for shipping damage. If you
find any damage, immediately contact the last carrier.
Verify that the coil has holding charge. Remove the cap
from the discharge stub and press the valve core. The coil
should have approximately 10 psi dry air holding charge.
If there is no charge, repressurize the coil and check for
leaks.
Verify that the liquid and discharge manifold is straight
and that the tubing is not displaced. Be extremely careful
with the stub for the common liquid line. Do not twist or
bend it. Refer to figure 1 for proper plumbing alignment.
NOTE -For units that have the fiquid line running up and
along the bottom of the control box, use the provided
liquid line adapter.

The installation section covers condenser coil installation
for the following units:
• HS26-030, -036, -042, -048, -060, HSXA15-060, and
HSXB15-060
• HS27-024, -030, -036, and -042
• HSXB15-024
• HXSB15-030, -036, -042 and HSXA19-036
• HSXB15-048 and HSXA19-038, -048, -060
HS26-030, -036, -042,-048,-060; HS27-024,-030,-036,
& -042; HSXA15-06; & HSXB15-060 Units
1 - Disconnect the power from the unit.

3- Reclaim the refrigerant from the unit.
- Remove top panel, coil guard, and mullions. Remove
the screws that attach the coil endplate which holds
the control box and compressor enclosure. Keep the
screws.
-Unscrew the high pressure switch from the liquid line.
(Not required if pressure switch is located next to the
service valve.) Keep the high pressure switch. Sweat
off the liquid line at the swedged joint next to the
pressure switch. See figure 2.
AI,IMPORTANT
5-Sweat off the discharge line with elbow at the
compressor. See figure 2.
NOTE -If the existing unit has a discharge loop close
to the compressor, and the common liquid line is
routed along the base of the unit, the discharge line
does not need to be replaced. It can be coupled
together using the provided 1/2" coupling.
6 -Remove the existing coil and the discharge line.
7 -Install the replacement coil assembly.
8-On the new coil, remove the holding charge by
depressing the valve core. Use a tubing cutter to cut
off the discharge stub approximately two inches from
capped end; this will also remove the pressure tap.

10 -If necessary, sweat in the provided liquid line adapter.
Be extremely careful not to twist or bend the liquid line
stub because a secondary failure can occur,
11 - Reinstall the pressure switch, Use a backup wrench
on the coil fitting to prevent twisting or stress to the
copper line.
12-Replace the top panel, coil guard, and mullions.
Replace the screws that attach the coil endplate that
holds the control box and compressor enclosure,
13-Refer to the unit installation instructions for leak
testing, evacuation, and start-up procedures. Charge
the unit as outlined in the installation instructions or
on the charging sticker.
14 -Once you have installed the replacement coil, start
the compressor and observe the discharge line.
Verify that there is minimal vibration between the
shock loop and the manifold on the outdoor coil's
discharge line,
15 -If there is visible motion after the shock loop has been
installed, apply weight kit number 38K46 to the
discharge line, Install the weight kit on the horizontal
run after the shock loop, or other suitable area to
achieve acceptable results, Rotate the weight kit on
the tubing to change vibration characteristics,
NOTE -Visible motion could result in a future failure
of the replacement coil.
HSXB15-024 Units
1 - Disconnect the power from the unit,
2 - Reclaim the refrigerant from the unit,
3 - Remove top panel, coil guard, and mullions. Remove

the control box and compressor enclosure, Keep the
screws,
4 -Unscrew the liquid service valve from the mounting
bracket and the tubing clamp from the base,
Sweat off the liquid line at the swedged joint next to
the coil outlet.
