PRE-INSTALLATION

Unpacking and Inspection

All  units  are  carefully  inspected  at  the  factory  throughout  the

manufacturing  process  under  a  strict  detailed  quality  assurance

program. All major components and sub-assemblies are carefully

tested for proper operation and verified for full compliance with

factory standards. Operational testing of some customer-furnished

components  such  as  DDC  (Direct-Digital  Controls)  controls,

pneumatic  control  valves  and  switches  may  be  a  possible

exception.

Each unit is carefully packaged for shipment to prevent damage

during normal transit and handling. Equipment should always be

stored  in  a  dry  and  covered  place,  and  in  proper  orientation

marked on the carton.

All shipments are made F.O.B. ex-factory and it is the responsibil

-

ity of the receiving party to inspect the equipment upon arrival.

Any obvious damage to the packaging and/or its contents should

be recorded on the bill of lading and a claim filed with the freight

carrier.

After inspecting condition of packaging exterior, carefully remove

each unit from the carton and inspect for hidden damage. Any hid

-

den  damage  or  missing  components  should  be  recorded  and

immediately reported to the carrier and a claim filed. In the event a

claim for shipping damage is filed, the unit, shipping carton, and

all packing must be retained for physical inspection by the freight

carrier. All equipment must be stored in the factory shipping car

-

ton with internal packing in place until installation.

At time of receipt, equipment type and arrangement must be veri

-

fied by review of order documents. Should any discrepancy be

found, the local Sales Representative must be notified immediate

-

ly so that proper action may be taken.

Should  any  questions  arise  concerning  field  warranty  repairs,

factory must be notified BEFORE any corrective action is taken.

When  repairs  or  alterations  can  be  accomplished  locally,  the

factory must be fully informed of the extent and expected cost

of repairs before work begins. When factory operations are re

-

quired, the factory must be contacted for authorization to return

equipment and a Return Authorization Number will be issued.

Unauthorized return shipments of equipment and shipments not

marked with an authorization number will be refused. In addition,

any claims for unauthorized expenses will not be accepted by the

manufacturer.

Prepare Job Site for Unit Installation

To save time and to reduce the possibility of costly errors, set up a

complete  sample  installation  in  a  typical  room  at  the  job  site.

Check all the critical dimensions such as field piping, wiring, and

duct connection to ensure they agree with job requirements. Refer

to job drawings and product dimension drawings as required. In

-

struct all trades in their part of the installation. Should any discrep

-

ancies be discovered, contact your local representative before con

-

tinuing with unit installations.

Identify and Prepare Units

For each unit, confirm incoming and control power requirements

match available power source. Refer to unit nameplate and wiring

diagram.

1. Review all tags on unit to determine if shipping screws are to

be removed. Remove screws as directed.

2. Rotate fan wheel by hand to ensure that fan is unrestricted

and can rotate freely. Inspect for shipping damage and fan

obstructions. Adjust blower wheel as required. 

Protect Units from Damage

Care must be taken to assure that no force or pressure is applied to

the coil, piping or drain stub-outs during handling. The equipment

covered in this manual IS NOT suitable for outdoor installations.

The equipment is never to be stored or installed where it may be

subjected to a hostile environment such as rain, snow, or extreme

temperatures.

Before,  during,  and  after  installation,  take  specific  caution  to

prevent foreign material such as paint, plaster, and drywall dust

from being deposited in the drain pan, on the motor or blower

wheels and cooling/heating coils. Failure to do so may have seri

-

ous adverse effects on unit operation, and in the case of motor

and blower assembly, may result in immediate or premature fail

-

ure and voiding all manufacturers’ warranties. Some units and/or

job  conditions  may  require  some  form  of temporary covering

during construction. While the manufacturer is not involved in

the design and selection of support methods and components, it

shall be noted that unacceptable system operating characteristics

and/or performance may result from improper or inadequate unit

structural support. After mounting, the unit is then ready for the

various service connections such as water, drain and electrical.

Verify which proper type of services are actually provided to the

unit. On  units  requiring chilled  water and/or  hot water, verify

proper line size and water supply availability.

INSTALLATION

Step 1 — Place Unit In Position

Install mixing box when ordered with unit. Follow mixing box in

-

stallation instructions outlined in the next section. 
HORIZONTAL UNITS
The horizontal blower coil units have 5/8 in. knockouts in each

corner of the top and bottom panels for 1/2 in. all threaded rods

(not  supplied  with  unit)  to  pass  through.  (See  Fig.  2.) Always

support the unit at the base until mounting is complete. 
VERTICAL UNITS
Vertical units need to be installed on a pad or on a base rail. The

height of the pad should be adequate to allow proper trapping for

condensate drain.

Sufficient  clearance must  be kept  for  service and  maintenance.

Minimum recommended clearance for maintenance of the motor

and blower wheel is 29 in. on the access side of the unit. Filters

can be removed from both sides and the bottom of the filter frame

(horizontal unit) or top of the filter frame (vertical unit). If side ac

-

cess to the filter is desired, the minimum clearance required is the

width of the filter rack plus 6 inches.

A minimum of 48 in. clearance is required between factory sup

-

plied electric heater and any combustible materials. See Fig. and

4 for additional clearances information. For drain pan or coil re

-

moval,  the  recommended  clearance  should  be  no  less  than  the

width of the unit plus connections.
