HDG Series Air Handler

INSTALLATION INSTRUCTIONS

Heat Controller, Inc.

•The drain line should be insulated where necessary to prevent sweating and damage due to conden- sate forming on the outside surface of the line.

•Make provisions for disconnecting and cleaning of the primary drain line should it become neces- sary. Install a 3 inch trap in the primary drain line as close to the unit as possible. Make sure that the top of the trap is below connection to the drain pan to allow complete drainage of pan (See Fig. 5).

•Auxiliary drain line should be run to a place where it will be noticeable if it becomes operational. Homeowner should be warned that a problem exists if water should begin running from the auxiliary drain line.

•Plug the unused drain connection with the plugs provided in the parts bag, using a thin layer of tef- lon paste, silicone or teflon tape to form a water tight seal.

•Test condensate drain pan and drain line after installation is complete. Pour water into drain pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no leaks are found in drain line fittings, and water is draining from the termination of the primary drain line.

8.2 Flowrator Piston Change

In most applications, there is no need to change the piston (orifice). However, in some applications, changing the piston size is required. If the application requires a different piston/flowrator, change the piston in the distributor of indoor coil before installing the coil. See Table 1 for orifice size.

To change the piston, use following steps:

1.Remove cover panel.

2.Use Two wrenches.

Loosen one turn to release pressure. (High pressure gas)

3.After releasing pressure.

Loosen and carefully pull a part the two fittings to expose piston.

4.Remove factory installed piston and replace with recommended piston from Table 1 as shown in Fig.7.

5.Carefully reassemble assembly. (Hand tighten)

Be sure to use teflon tape on thread for a complete seal.

6.Hand tighten and make sure assembly is properly connected and then torque to 10-30 ft/lb. NOTE: Be careful not to bend tubing
