I. UNCRATING
Carefully examine the carton(s) for damage before opening. If
the carton is damaged, immediately notify shipping company.
If the unit(s) were shipped on wooden skids, remove protec-
tive wood and banding straps securing the carton(s) to the
skid. Open the carton(s) and remove all protective packaging.
Immediately verify that the electrical rating nameplate located
on the cover matches electrical power supply available. Retain
the shipping carton(s) until the unit(s) is installed and properly
operating.
ACCESSORIES: If the unit(s) was ordered with optional elec-
trical accessories, the accessories may be found in the carton
containing the unit or in a separate carton(s) accompanying
the unit(s). Check all of the cartons/skids for accessories before
discarding.
II. MOUNTING INSTRUCTIONS
(General Notes for All Mounting Congurations)
NOTE: Models with Electric Heat - INDOOR MOUNTING ONLY!
Environmental/Insect/Dust & Fume Control
The Drive-Thru Unit 3 air curtain is designed to be an eec-
tive barrier against cold drafts in the winter and hot air in the
summer. To achieve optimum protection, the unit should be
mounted on the inside of the building, as close to the top of
the window opening as possible. To ensure peak performance,
keep the air stream free of obstructions. The unit is equipped
with mounting brackets to ensure proper mounting in most
applications.
The air curtain will not perform properly if negative air
pressure exists in the building. Under these conditions,
a means for makeup air to the building must be provided
so that the air pressure on both sides of the opening is in
balance.
Before mounting the unit, check the supporting structure to
verify that it has sucient load-carrying capacity to support
the weight of the unit(s). The mounting hardware should be
capable of supporting a minimum of three (3) times the weight
of the unit (See Table 1). B. For optimum performance, the bottom of the unit (discharge
nozzle) should be no more than 1” above the top of the
drive-thru window opening with the unit mounted ush to the
wall. If the unit must be mounted higher, it must be spaced
out from the wall 3/8” for every inch the unit is above the
drive-thru window opening.
C. Electric heated units shall:
1. Have a minimum clearance of at least 1” between the sides
and top of the unit and any combustible material.
2. Have a minimum clearance of at least 18” between the bot-
tom of the unit and the counter.
TABLE 1
DRAWING 1
A. When determining the mounting location for the unit(s), make
sure that nothing interferes with the curtain of air developed
when the discharge vanes are directed from 0º to 20º toward
the drive-thru window opening. If the air stream strikes any
obstruction (the top edge of the window, a window open-
ing device, etc.), the eectiveness of the unit will be greatly
reduced (See Drawing 1).
