Installation
CAUTION: The installation must be
conducted by a qualified technician.
Receiving And Handling
Trane HCCA Fan Coil units are packaged in
individual cartons for maximum protection
during shipment, as well as for easy
handling and storage on the job site.
To protect against loss from in-transit
damage, complete the following upon receipt
of the units:
1. Inspect individual pieces of the shipment
before accepting it. Check for rattles, bent
corners on cartons or other visible
indications of shipping damage.
2. If a carton has apparent damage, open it
immediately and inspect the contents
before accepting the unit. Do not refuse
the shipment. Make specific notations
concerning the damage on the freight bill.
Check the unit casing, fan rotation, coils,
drain pan, filters and all options.
3. Inspect the unit for concealed damage
before it is stored and as soon as possible
after delivery.
4. Do not remove damaged material from
the receiving location if possible. It is the
receiver's responsibility to provide
reasonable evidence that concealed
damage was not incurred after delivery.
5. If concealed damage is discovered, stop
unpacking the shipment. Retain all
internal packing materials and original
cartons. Take photos of the damaged
material if possible.
6. Notify the carrier's terminal of damage
immediately by phone and mail if any
damage is found. Request an immediate
joint inspection of the damage by the
carrier and consignee.
7. Notify the Trane sales representative of
the damage and arrange for repair. Do not
repair the unit, however, until damage is
inspected by the carrier's representative.
Installation Considerations
For proper installation and operation, check
each of the followings before mounting the
units:
1. Allow adequate space for the unit and free
area or service clearances. See Figures
5, 6, 7 and 8 for general unit dimensions.
For other dimensions refer to the
submittal drawings provided by Trane
Sales Office not in carton. For servicing
and routine maintenance, must provide
access to the unit through removable
panels in the ceiling.
2. Before installing any unit make sure
proper preparation has been made at
each unit location for piping and electrical
connections.
3. Check that the supporting structure is
strong enough to support the operating
weights, as given on Table 1.
4. The clearance between drain pan and
ceiling should be enough for drain line
pitch with a minimun slope of 1:50.
5. Ducting connected to units (where
applicable) should not exceed the external
static pressure rating of the unit.
6. Condensate protection for the chilled
water valves and piping must be provided
by installer. A drain pan extension
provided by installer should be located
under the valves or else the valves and
piping should be thoroughly insulated.
7. Units with valve package are equipped
with long drain pan which can carry the
condensation from water valves.
Insulation of valve package is not
required.
Mounting
The Trane model HCCA units are designed
to be suspended from the ceiling on 3/8-16
threaded rods furnished by the installer.
Holes are provided at the top of the unit, see
Figures 5, 6, 7 and 8 for cutout dimensions
and locations.
To install the Trane model HCCA, complete
the following:
1. Install the suspension rods or other
suspension devices which must be
provided by the installer.
2. Put the upper W3/8 nuts and W3/8 lock
washers on suspension rods to prevent
unit from upward tilting during unit
operation or duct installation, as shown on
Figure 2 Typical Installion.
3. Hoist the unit into position. See Table 2 for
unit net weights.
CAUTION: Due to the heavy weights.
ensure safety of all nearby installers
when hoisting the unit.
4. Put on the lower W3/8 lock washers and
then W3/8 nuts to secure the unit, as
shown on Figure 2 Typical Installion.
5. Place the unit to desired angle by
adjusting lower nuts up/down, and then
tignten the upper nuts.
6. Adjust the slope of the drain pan by
turning the drain pan suspension screws
up/down. The drain pan should be pitched
to provide proper drainage. Note side to
side as ewll as end to end level. See rain
”Pan Leveling” in maintenance procedures
for more details.
Note: Level the unit by checking on the
unit casing. Do not use the coil or drain
pan for leveling as they are pitched to
provide proper drainage.
