into horizontal pan as shown with coil endplates fitting into “V” shaped supports in the
front and back of the horizontal pan. Mounting tabs on vertical drain pan fit over the
air inlet side of the horizontal pan with vertical pan inside horizontal drain pan.
Horizontal pan must be under indoor coil when in the installed position. Note primary
and auxiliary drain pan positions for horizontal right vs. horizontal left. Drain connec-
tion with 3/4” hole must be connected to primary drain. Connection with 3/8” knockout
is the secondary drain connection.
Electrical connections may be made from the top or bottom of the unit. Refrigerant
and condensate drain connections must be made on the front of the unit. (See unit
dimensions and horizontal right hand supply and horizontal left hand supply, Figures
3, 6 & 7.)
IMPORTANT: Units cannot be installed horizontally laying on or suspended from the
back of the unit. Horizontal units must be supported or suspended from one side or the
other when in the horizontal position.
• Support along the length of the unit, all units installed horizontally. Do not support or
suspend unit from both ends without support in the center of the cabinet. If unit is to
be supported or suspended from corners, run two reinforcing rails length of unit and
support or suspend from reinforcing rails.
NOTE: When converting a vertical upflow to horizontal, the foam tape must be removed
from both sides of the vertical pan going into the horizontal pan. When converting a
horizontal left-hand to horizontal right-hand, the foam tape must be moved to the
appropriate location.
3.0 ELECTRICAL WIRING
Field wiring must comply with the National Electric Code (C.E.C. in Canada) and any
applicable local ordinance.
3.1 POWER WIRING
It is important that proper electrical power is available for connection to the unit model
being installed. See the unit nameplate, wiring diagram and electrical data in the installa-
tion instructions.
• If required, install a branch circuit disconnect of adequate size, located within sight of,
and readily accessible to the unit.
• Units with factory installed circuit breaker(s) meet UL and CSA requirements as a ser-
vice disconnect and should make above requirement for a field installed branch circuit
disconnect unnecessary.
• IMPORTANT: Units may be equipped with one, two, or three 60 amp. circuit breakers.
These breaker(s) protect the internal wiring in the event of a short circuit and serve as
a disconnect. Circuit breakers installed within the unit do not provide over-current pro-
tection of the supply wiring and therefore may be sized larger than the branch circuit
protection.
• Supply circuit power wiring must be 75°C minimum copper conductors only. See elec-
trical data for ampacity, wire size and circuit protector requirement. Supply circuit pro-
tective devices may be either fuses or “HACR” type circuit breakers.
• Power wiring may be connected to either the right or left side (vertical) top or bottom
(horizontal). A 7/8”, 1-3/32” dia. concentric knockout is provided for connection of
power wiring to unit. If a larger opening is required, dependent upon kW electric heat
supplied, pull appropriate size hole required for conduit size being used. Using a con-
duit hole punch (Greenlee type), center punch using outside cabinet around 7/8”
knockout as a template to center punch location and punch desired hole size. Holes
may be punched for any size conduit up to a 2” hole for 1-1/2” con duit.
• Power wiring is connected to either the power terminal block or circuit breaker(s) in
unit control compartment.
• Single phase units above 10.5 kW may be supplied with circuit breaker(s) requiring
separate supply circuits. Units come standard with a jumper bar assembly connecting
separate circuits into one single supply circuit (excluding 18 kW and 21 kW “C” volt-
age units).
