Inspect the coil for shipping damage- Notify the transporta-fiou company immediately ff the coil is damaged.

B. APPLICATION INFORMATIONL FURNACE AND COIL

NOTE:These _'ells are for use with outdoor products using R-410Arefrigerant only.

The following steps are to be ccu_dered when _ t_erefrigerantlh_es:

a. Determine the most practical way to run the ltocg.

b. Consider typesofbend_ to be made and spacelimitations.

1. Remove both seals from the indoor cog. The braze capsare son sold_.

2. Field supplied tublng should be cut square, toured andfree ofbun-e at'the cormectlilg end. Clean the tubing toprevent contaminant_ from enterlng the system.

3. Run the refrigerant tubing into the efl;ub tubesockets of the in_oor unit ceiL

6, Use good brazing technique to mnke leakproofjoint_.

7. Minhnlze the use o_ _arp 90" bends.

8. Insulato the suction line and its fittings.

9, Do NOT allow _minsu|at, ed lincs to come into contactwith each other.

Do not open refdgerent valve at the outdoor unit until therefftgerant lines and coil have been brazed, evacuated, andleak checked. This would cause contamination of therefrigerant or po_$1btedischarge of refdgeran! to theatmosphere.
