Initial Check IMPOR T ANT : Do not attempt to start unit, even mo- mentarily , until all items on the Start-Up Checklist and the following steps have been completed. 1. V erify unit has been installed per the Installation section of this literature. 2.
When the first-stage thermostat is satisfied, first-stage main gas valve and the pilot valve close. Induced-draft motor shuts of f. T ime-delay relay (built into constant volume control board) opens and timer sequence begins. When sequence is com- plete (after 1 10 ± 5 seconds) evaporator-fan motor shuts of f.
LIQUID SER VICE V AL VES, FIL TER DRIERS, AND SIGHT GLASSES Sizes 034 and 044 — Access to these components is through the access panel on the right side of the unit. See Fig. 34. There is also a Schrader port in each suction line that is ac- cessible through this same panel.
ECONOMIZER DAMPER MOTOR — On units so equipped, the economizer motor is located in the mixing box section. Access to it is through the doors labeled FIL TER SECTION on the sides of the unit.
NOTE: Only the heater element contactors are located in the heater box. The heaters are located in the unit airstream. 25% OUTDOOR-AIR DAMPER — Access to adjust the damper is through the hoods. Remove filters to gain access into unit to adjust linkage arms.
Adjustments EV APORA TOR F AN AND POWER EXHAUST MOTOR PLA TE — Adjust using a 15 ⁄ 16 -in. wrench on the adjusting bolts: 1. Loosen holddown bolts. (See Fig. 44.) 2. T urn the adjusting bolts to move the motor mounting plate toward or away from the fan to loosen or tighten the belts.
25% OUTDOOR-AIR DAMPER — See Manual Outdoor- Air Damper section on page 10 for adjustment details. REFRIGERANT CHARGE — All units are shipped with a complete operating charge of R-22.

AUTOMA TIC PILOT ADJUSTMENT (48 Series Units Only) 1. Set system selector switch at OFF position to shut of f unit. T urn of f power to unit. 2. Remove screw cap cover on pilot gas valve to expose adjusting screw . 3. T o ensure that main burners do not ignite, remove wire from gas valve terminal 2.
GAS V AL VE ADJUSTMENT (48 Series Units Only) — The gas valve opens and closes in response to the thermostat or limit control. When power is supplied to valve terminal 3 (D1 on low heat), the pilot valve opens to the preset posi- tion. When power is supplied to terminal 2 (W1 on low heat), the main valve opens to its preset position.
Moisture/Liquid Indicator — A clear flow of liquid refrigerant indicates suf f icient charge in the system. Bubbles indicate undercharged system or the presence of noncon- densables.
