Compressor Triac Replacement Relay - ASY-503-X2D

Compressor Triac Replacement Relay - ASY-503-X2D

These relays are normally used for replacing three terminal compressor control triac devices in Cruisair marine applications. They are required for use in 208 to 240-volt Cruisair marine EasyStart Applications but are not required for 100 to 120-volt applications. They can also be used in applications where triac noise or premature failure may occur.

Compressor Triac Replacement Relay

When used with a high-current triac that controls the compressor switching, EasyStart requires that the triac be replaced with a power relay. This replacement relay is design with mounting that matches the footprint of the Sanrex® TG35F40 triac, commonly used in marine air conditioners.

Specifications

Features

• The relay comes with two nylon standoffs and two screws for mounting in the same stud locations as the triac.

Installation 

1. ALWAYS COMPLETELY REMOVE AC POWER.
2. Remove the wires from the triac leaving the wires connected to the board.
3. Remove the triac and mounting hardware.
4. Wipe off any white grease that remains in the electrical box.
5. Install two #4-40 bolts in the holes where the triac was installed and install the board using the supplied standoffs between the board and the case.
6. Connect the wires as shown in figure 1. Support the underside of the board with your finger while inserting the push on connections to prevent breaking the board or the stand-off.

IMPORTANT INSTALLATION NOTE FOR CRUISAIR MARINE CUSTOMERS ONLY:

• When installing EasyStart into 220-240V SMX A-288/282/281 control applications that use the triac to switch power to the compressor, it is necessary to replace the triac with a relay. If the triac is not replaced, the EasyStart and any pump relay triggers may suffer damage and ultimately fail.
