13 Achieving 1.4% Low Leakage Rate

Ensure all the gaskets remain intact on all surfaces as shipped

with the unit. These surfaces are areas between the upper

tie plate and blower access panel, blower access and coil

access panels, and between the coil access and filter access

panels. Ensure upon installation, that the plastic breaker

cover is sitting flush on the blower access panel and all ac-

cess panels are flush with each other and the cabinet. With

these requirements satisfied, the unit achieves less than 1.4%

airflow leakage when tested in accordance with ASHRAE Stan-

dard 193.

14 Start-Up Procedure

HIGH VOLTAGE!

Disconnect ALL power before servicing or

installing this unit. Multiple power sources may

be present. Failure to do so may cause property

damage, personal injury or death.

• Prior to start-up, ensure that all electrical wires are

properly sized and all connections are properly tight-

ened.

• All panels must be in place and secured. For Air Tight

application, gasket must be positioned at prescribed

locations to achieve 1.4% leakage.

• Tubing must be leak free.

• Condensate line must be trapped and pitched to al-

low for drainage.

• Low voltage wiring is properly connected.

• Auxiliary drain is installed when necessary and pitched

to allow for drainage.

• Unit is protected from vehicular or other physical dam-

age.

• Return air is not obtained from, nor are there any re-

turn air duct joints that are unsealed in, areas where

there may be objectionable odors, flammable vapors

or products of combustion such as carbon monoxide

(CO), which may cause serious personal injury or death.

15 Regular Maintenance

The only item required to be maintained on a regular basis

by the user is the circulating air filter(s). Filter should be

cleaned or replaced regularly, typically once per month. A

certified service technician must perform all other services.

IMPORTANT NOTE: If thumb screws are used to access the

filter, ensure the washer installed on the screw behind the

access panel remains in place after re-installation.
