All installations and services must be performed by qualified personnel.

INSTALLATIONS OF A-COIL IN HORIZONTAL APPLICATION

For the AH1-A, in all A-coil applications (1024E, 1030E, 1036E, and 1224-30G1) except the 1236G1, the A-coil spacer must be used.

For the AH2-A, in all A-coil applications the A-coil spacer must be used.

1.Remove bottom door of air handler.

2.Remove middle door of air handler.

3.Slide primary drain pan out of unit.

4.Set A-coil spacer in primary drain pan if needed. See Figure B2, #1 inset.

5.Set A-coil in place on primary drain pan.

6.Secure coil installation strip with aluminum tape as indicated in Figure B2, inset #2. This makes a small ramp to slide the coil up and on the rear pocket brake.

7.Slide pan with coil into air handler making sure that the A-coil plastic pan is properly positioned in the primary drain pan. Insure the plastic coil pan on base of the A-coil slides into rear clip. See Figure B2.

8.Secure front of plastic pan to bottom of unit with supplied pan clip. See Figure B3 inset. An extension for nut driver may be of benefit.

9.Pan should rest on pocket brakes on each side of side casing when properly installed. IMPORTANT: When air handler is installed in attic above a finished ceiling, it is recommended that a safety overflow pan with its own separate drain be installed under the entire unit.

10.Remove trim plate from A-coil connections.

11.Cut out appropriate holes in insulation, remove appropriate knockouts, and realign coil access panel and secure into place

12.Make appropriate liquid and suction line connections to coil and braze connections. NOTE: A wet rag makes an excellent heat sink for tubing.

: If drilling or screwing into panel of plate is necessary, make certain drill does not penetrate into any part of evaporator coil or hot water coil to avoid personal injury and/or property damage.
