Unit Access
The TRL series is unique to the
ClimateMaster product line in the way
installers and service technicians’ interface
with the product. Traditionally for horizontal
products unit controls/electrical connections
are accessed from the unit’s front access
panel, blowers are accessed through the
side or back panel, and water/refrigerant
circuit repairs require the unit to be brought
down from the ceiling installation.
On TRL products the unit controls,
electrical components, water components/
circuit, the refrigeration components/
circuit, optional power disconnect, service
tool connection, drain pan, air coil, air filter,
and blower motor can be accessed from
the bottom of the unit (see Figures 7 and
8). This greatly increases the installers
and service technicians’ ability to access
and interface the water source heat pump
while it is installed in the ceiling.
The product is also designed to be
accessed in many of the traditional ways
as well. The unique control box design
ships from ClimateMaster facing down for
bottom access but can be flipped up in
the field for front access. This allows those
who interface with the product to access
the unit controls either from the bottom
or from the front of the unit. See Figures 9
and 10 for details.
Alternatively, if the unit requires tabletop
service on the control box, the TRL
product is designed with a rotation feature
to allow installer or service technician to
interact with the control panel from the
front of the unit. The user will need to
remove the top and front access panels
from the unit, remove the 2 screws that
hold the control panel facing down, rotate
the control panel and lock it at 45 degrees
with the pivotal element on the right side
of the panel control support. See Figure
11 for details.
The complete blower assembly can be
slid down from the bottom of the unit.
The is a safety latch in place to prevent
the blower assembly from dropping
when the bottom blower access panel
is removed. Remove the screw and pull
back on the latch to slide the blower
assembly down. The assembly will rest
on a service rail where the technician may
service the motor or remove the whole
assembly by disconnecting one electrical
quick connector.
The TRL condensate drain pan can be
accessed for service or removal from
the bottom of the unit. After removing
the external condensate line connection,
remove the drain pan access panel. First,
remove the condensate sensor clip from
the pan and set it to the side. Next remove
the drain pan set screw located next to
the compressor side of the unit. Then
hold the drain pan and slide it towards
the back of the unit until the condensate
pan is pushed all the way against the back
access panel. Lastly, allow the opposite
side of the pan to drop down and then
slowly slide the drain pan down allowing
the drain pan nipple to be pulled through
the access panel opening with out
damaging the connection threads.
