CAUTION - COIL MAY BE UNSTABLE ON FORKS 

AND SHOULD BE SECURED FROM TIPPING BY 

ATTACHING CABLES OR CHAINS FROM TOP OF 

UNIT TO VERTICAL TRACKS OF FORK LIFT.

E. Optional Factory Service

Periodic service on any piece of mechanical 

equipment is necessary for efficient operation. L.J. 

Wing has a nationwide service organization available 

to provide quick and dependable servicing of heating 

coils. Wing also offers factory start-up service which 

includes the presence of a service engineer to 

supervise the initial start-up and adjustment of the 

equipment and provide instructions for the owner’s 

maintenance personnel in proper operations and 

maintenance. Consult factory for quotations on 

periodic or start-up service.

SECTION III - INSTALLATION AND MOUNTING PROCEDURE

A.   The Wing Coil must be installed with the tubes 

vertical for proper drainage. The coils are designed 

for vertical mounting only (horizontal air flow).

B.   At least 6" clearance should be provided above 

and below coil for access to tubes and headers in 

the event that future tube replacement or repairs are 

necessary. 6" clearance should also be provided on 

the damper motor and control linkage side of the coil 

for service access.

C.   The coils can be supported on the integral mounting 

flange or on angle iron legs attached to the duct mounting 

flanges. Additional supports may be required in the 

center for long coils.

D.   The Wing coil must be installed with headers 

level for proper condensate drainage. To insure 

proper leveling, use a spirit level. Do not level by 

measurement only.

E.   Return steam condensate or hot water header 

is securely bolted to the lower mounting bracket to 

prevent damage to the header and tubes during 

shipment. (See Figure 1.) Shipping bolts must be 

removed before applying steam or hot water, but 

after all piping connections are made. Failure to do 

so will void factory warranty.

Figure 1 - Shipping Bolt Locations (C-000703)

F.   Remove shipping braces before attaching 

ductwork.

G.   Ductwork can be attached to the coil flanges or the 

coil can stand in a duct with bulkhead plates blanking 

off spaces around the coil. The flanges must not be 

used to support the ductwork.

COIL INSTALLATION AND LOCATION

1.  Sheet metal isolation plates should be installed 

on the top and bottom of the coil to eliminate 

air flow over the supply and return headers, top 

and bottom headers should be insulated and/or 

isolated on both sides of the coil.

2.  Cooling coils should be located downstream at a 

distance no less than 36 inches from the outlet 

flange of the coil. Freezestat location should also 

follow this same guideline. Coils operating in VAV 

systems, or those operating at lower or higher than 

recommended air velocities, should be fitted with 

anti-stratification baffles.

3.   The installation of humidifiers with steam 

manifolds internal of an air handler may provide a 

temperature override to the system. Internal steam 

manifolds and piping should be insulated.

TEMPERATURE CONTROL

1.  The airstream thermostat control to the coils 

should be located a minimum of 36” downstream. 

Each coil should have its own temperature control 

system.

2.  Freezestats mounted on the face of the cooling 

coils should be located a minimum of 36” 

downstream of the coil flange. Optional anti-

stratification baffles are available to reduce this 

spacing to 24”.

3.  Coils operating at lower or higher than 

recommended air velocities or in VAV systems 

should be fitted with optional anti-stratification 

baffles.
