RECEIVING:

Upon receipt, examine units carefully for in-transit 

damage or missing components as detailed in packing 

list. If damaged, report damage(s) to trucking company, 

take pictures, and contact Cambridge Air Solutions.

After uncrating unit, verify that it is the proper size and 

that all loose parts are included.

NOTE: Inspect the exterior and interior of the equipment 

carefully for any damage that may have occurred during 

shipment. Verify shipped loose parts are complete and 

undamaged. Ensure there is no damage to protruding 

exterior components such as door handles, disconnect 

switch handle, etc. or to internal components such as 

pumps, media, filters, louvers and drains.

INSTALLATION:

WARNING:

Do not remove unit from shipping skid until it 

is at the installation location. Moving these units 

when not properly secured to the skid can result in 

personal injury or death and can seriously damage 

the unit.

WARNING:

To prevent injury or death, and damage to unit, 

ensure the lifting capacity of the moving equipment 

exceeds the weight of the unit by an adequate 

safety margin.

NOTE: Ensure all local building and electrical codes are 

fully complied with in installing the unit. 

Take the following factors into consideration before 

selecting the location of installation:

  •   Ensure sufficient clearance, per the submittal, to 

allow easy access for maintenance and system 

operation.

  •   Unit must be installed on a level foundation 

that allows for proper flow of condensation into 

internal drains, sufficient to support continuous 

to full perimeter of base and cross members, and 

minimize deflection of unit base frame to no more 

than 1/16th “ (1.6mm) over the length and width of 

unit.

WARNING:

To prevent injury or death, disconnect electrical 

power source before completing connection to 

the unit. All wiring must comply with National 

Electrical Code (NEC) and state and local 

requirements. Outside the United States, the 

national and or local electrical requirements of 

other countries shall apply.

The installing contractor must connect appropriate 

power wiring to the terminal block or non-fused, 

unit-mounted disconnect in the power section of 

the unit control panel.

WARNING:

During installation, testing, servicing, and 

troubleshooting of this product, it may be necessary 

to work with    live electrical components. To 

prevent injury or death due to electrocution, take 

extreme care when performing service procedures 

with electrical power energized. Have a qualified 

licensed electrician or other individual who has 

been properly trained in handling live electrical 

components perform these tasks. Failure to 

follow all safety precautions when exposed to 

live electrical components could result in death or 

serious injury.

 

1.   All installation should be performed in accordance to 

local and state codes and with proper permits.

2.   Measure the unit for correct sizes compared to the 

submittal. Immediately contact Cambridge Air 

Solutions if the unit’s openings do not match.

3.   Check for proper air flow direction.

4.   Set the unit in place. Make sure the unit covers the 

entire air inlet opening.

5.   Fasten the unit in place with the self-drilling screws 

provided with the unit.

NOTE: Take care not to drill or screw into sump tank.

6.   Check for air leakage. Air leakage will lower the 

efficiency of the unit.

7.   Check that the unit is level for proper water transfer 

through the system.

8.   Check that the sump pump has a good seal to the 

floor.
