Design and Take-off Precautions
Attention should be paid to the height of drywall which encapsulates ductwork in a bulkhead. Note the
height of the side supply air opening shown in the submittal and ensure that the drywall does not interfere
with the side wall grille. Make allowance for the 1” flange around the grille. Call Temspec at the time of
submittal review if side supply air openings need to be lowered or rotated to a vertical position to avoid
interference with walls or doors.
Temspec does not include wall sleeves which might be needed to bridge a gap between the grille collar
on the unit and the drywall surface, howsoever caused. Also floor sleeves, extension sleeves through
shear walls and extension of thermostat speed switch wiring through shear walls are not included.
It is important to accurately locate the floor sleeve relative to the fan coil and the drywall. If subsequently a
wall sleeve is used because the unit is incorrectly located back from the face of the drywall, a problem with
access for servicing can arise if the sleeve depth is too long (over 4”). Also note that the return air panel
of the type which attaches with quarter-turn fasteners cannot be used with a sleeve and ½” drywall must be
attached directly to the front of the unit.
Inspection Upon Receipt of Equipment
•
The entire shipment should be inspected for damage, either readily visible or concealed. Any
damage must be noted on the freight bill by the carrier’s agent and Temspec notified within 24
hours.
•
Remove the inlet service panel and check the fan wheel for free rotation by spinning it manually.
Slight misalignment can be corrected by repositioning the motor or by loosening the fan hub set
screw and repositioning the fan on the motor shaft.
•
Check riser projections at each end of the cabinet for damage that would prevent making an
acceptable piping connection.
•
Check internal piping, coil and valve packages for possible transit damage. If contractor /
installer deem it necessary to tighten mechanical fittings Temspec does not assume any
responsibility for this procedure. It is stressed that the component manufacturer's recommended
procedures be strictly followed.
•
Thermostats, speed switches and other accessories which have been shipped separately should
be inspected for quantity and transit damage.
•
Two-way Control Valves.
•
When two way valves are used, pump and chiller bypass or pump speed control must
be included in the system. This is necessary to ensure that the close-off pressure rating of
the valve is not exceeded. This also helps to minimize noises during the shoulder season.
The maximum close-off pressure rating is given in the submittals.
•
Electrical Connection
•
It is assumed that the fan coil unit will be in a dedicated electrical circuit. If the unit is
to be in a circuit which includes electrical outlets or other electrical devices, Temspec
must be informed prior to releasing the units for production.
Handling
The fan coil units must be handled with the due care required for an HVAC unit. Avoid dropping or jarring
the unit during offloading and moving the unit into position. Do not lift the unit using the riser pipes.
