!WARNING !

Moving parts can cause personal injury. Exercise all due caution when test running the chassis.

!WARNING !

The correct condenser air baffles must be properly installed or performance will be impaired and/or the warrantywill be voided!!

PREPARATION FOR INSTALLATION

IMPORTANT: RetroAire Dual Motor PTACs are to be used with metal wallsleeves. The sleeves must employ front panels secured by screws that prevent contact with all parts with minor dimensions of openings not exceeding 1/2”.The final assembly must employ an indoor air discharge grill having dimensions not less than 26” x 4”, separating the top surface of the chassis from the top surface of the discharge grill by a minimum of 1”. For all models, the outdoor openingsmustpreventcontactofallmovingpartsbymeans of louvers or grills with minor dimension not exceeding 1”. All cord connected 265 Volt units must be plugged into receptacles within the unit subbase or chassis.

1.Remove the front of the existing room enclosure. This will expose the old chassis.

2.Disconnect the power supply. If a line cord and plug were used, remove it from the receptacle. If the chassis is hard wired, locate the circuit breaker, place it in the “OFF” position, and tag it, announcing work is being done. DO NOT TURN ON.

3.Loosen any tie down bolts or screws and remove the old chassis.

IMPORTANT: Dispose of old chassis per present state and federal regulations.

4.Inspect the wall sleeve/cabinet for rust, holes, and damage.Cleanthewallsleeveofanydirt,repairanydamage, and ensure proper drainage of condensate or rainwater to exterior of building.

5.Remove or repair old weather seals and note location for installation of any new seals.

6.Check the wall sleeve/cabinet to assure all drain holes are open and that (A) the unit is level left to right and (B) the back is pitched to the outside by 1/2” maximum.

7.Check the present voltage to verify the new chassis is a matching voltage and that the line cord and receptacle match.

8.Before installing the new chassis, inspect the outdoor louver for a minimum free area of 70% and remove any obstructions. Any variation will restrict air flow over the condenser coil and cause serious damage to the chassis. It will also void the warranty.
